1 INTRODUCTION
1�1 GENERAL
This manual serves as a guideline for the safe and eecve op-
eraon, maintenance and possible correcon of minor malfunc-
ons of genverters for marine applicaons manufactured and
marketed by WhisperPower.
It is therefore essenal that every person who works on or
with the genverters should be familiar with the contents of this
manual, and that he/she should carefully follow the instrucons
contained herein. Both safety and durability depend very much
on the correct idencaon, installaon and the correct under-
standing of rangs, features, design, maintenance and operaon
procedures.
The informaon, specicaons, illustraons and statements con-
tained within this publicaon are given with our best intenons
and are believed to be correct at the me of going to press.
All of the specicaons, provisions and instrucons contained
in this manual apply solely to standard versions of genverters
delivered by WhisperPower.
This manual is valid for the following models:

Our policy is one of connued development and we reserve the
right to amend any technical informaon without prior noce.
Whilst every eort is made to ensure the accuracy of the parc-
ulars contained within this publicaon neither the manufacturer
nor the distributor or dealer in any circumstances shall be held
liable for any inaccuracy or for the consequences thereof.
1�2 SERVICE AND MAINTENANCE
Regular service and maintenance should be carried out according
to the direcons in this manual. For service and maintenance,
turn to the manufacturer or a dealer.
1�3 GUARANTEE
WhisperPower guarantees that this genverter has been built
according to the principles of good workmanship, according
to the specicaons in this manual and according to European
Community safety regulaons.
During producon and prior to delivery, all of our genverters are
tested and inspected.
This genverter’s correct operaon is subject to guarantee. The
period and condions of this guarantee are laid down in the
general condions of delivery as registered with the Chamber
of Commerce and Industries for the North of the Netherlands
number 01120025 and are available on request. The guarantee
period is two years, limited to 1000 running hours. Some aspects
of our guarantee scheme are given here in more detail.
Guarantee does not cover failures caused by misuse, neglect or
faulty installaon.
Example 1: Faulty installaon
Seawater entering the engine is the most common cause of
damage to combuson engines (both propulsion and generator
engines) in boats. The entry of water must be avoided under all
condions. Be aware that the condions in blue water sailing can
be extreme. Refer to the installaon manual for instrucons but
remember these are for guidance only as many factors inuence
the installaon of the genverter. The ulmate responsibility will
always be with the owner. If in doubt, ask!
Example 2: Misuse
Long term running with no load or too lile load can cause the
exhaust to get choked with soot or carbon. Cleaning the exhaust
is not covered by guarantee.
Example 3: Neglect
Somemes the seal of the raw water pump starts leaking. Mostly
this begins with a lile drip and it slowly gets worse. Regular
visual inspecon of the genverter is necessary to prevent damage
from occurring due to a leaking water pump. When serious
damage is discovered aer weeks of neglect, guarantee claims
will not be honoured.
Example 4: Neglect
A WhisperPower genverter has an opon for an auto start/stop
mode or interval mode. WhisperPower cannot be held respon-
sible for damage caused by the genverter running unaended.
Oil changes must be carried out according to the maintenance
schedule.
Guarantee means that faulty parts are repaired or replaced free
of charge. If necessary the whole genverter unit will be ex-
changed. Labour necessary to complete repairs on board a vessel
by an authorized service engineer is covered, but is limited to a
reasonable number of hours and reasonable rates in relaon to
the actual repair work that has to be done.
Travel expenses and travel hours are not covered, neither is the
labour required to take a genverter out of a vessel or for rein-
stallaon. There is no cover for labour needed to get access to
the genverter, for example to remove equipment or parts of the
vessel’s structure or hull.
Goods to be delivered under guarantee will be invoiced. Only
aer the faulty goods are returned will the invoice be credited.

Piccolo Marine Diesel Genverter 2 | 3 | 3+ | 8 | 10 | 12 | 15 | 18 5
Payment in advance may be required or guaranteed by credit
card. If the faulty goods show that the failure was not covered by
guarantee, a credit will not be issued. For example, if a Printed
Circuit Board is returned with clear damage caused by water,
guarantee will be refused.
Freight costs to deliver spares by normal mail or carriers are
covered under guarantee. Special services like express mail,
overnight delivery, etc. are not covered. Taxes and dues are
not covered. For shipments to remote areas any addional costs
incurred over normal carriage will be invoiced to the customer.
The cost for returning faulty goods is not covered by guarantee.
If any problem arises which could be subject of guarantee,
procedures should be followed as described in the guarantee
condions, unauthorized repairs could lead to further damage
and violate the guarantee condions.

1�4 LIABILITY
WhisperPower does not accept responsibility for damage,
injuries or casuales which are the result of operaon of the
genverter in specic condions bringing dangers which could not
be foreseen, or could be avoided by addional measures. Whis-
perPower does not accept liability for damage due to use of the
genverter, possible errors in the manuals and the results thereof.
Automacstart/stop: WhisperPower cannot be held
responsible for damage caused by the genverter
running unaended using the auto- start/stop mode
or interval mode.
1�5 IDENTIFICATION
1�5�1 General
Before using this genverter it is very important to idenfy the
model correctly. To communicate for service or ordering parts
it is also essenal to correctly idenfy the genverter. For the
daily operaon of the genverter it is necessary that the operator
knows the correct specicaons as well.
1�5�2 Idencaonplate
All required idencaon data are on the idencaon plate.
The idencaon plate also menons some basic features of the
genverter.
SERIAL NUMBER: The identy of the genverter is given by the
serial number. Using this number, the manufacturer can trace the
specicaons of the genverter.
POWER: The idencaon plate gives the maximum load in kW,
i.e. kVA calculated with power factor one. When calculang a
load one should always take into account the power factor or cos
phi of this load. The resulng load should not exceed the nominal
power as shown on the idencaon plate. Power is rated at
an ambient temperature of 25°C. For higher temperatures the
genverter has to be de-rated.
Figure 1: Idencaon plate
VOLTAGE: The Permanent Magnet Alternator (PMA) generates
a variable voltage between 250V and 400V. Depending on the
type of installaon, this is converted by a DC PowerCube or an AC
Power Module for Genverter
FREQUENCY: The Permanent Magnet Alternator output frequen-
cy is considerably higher than in in common alternang current
installaon. The DC PowerCube and WP-PMG (Power Module for
Genverter), however, are designed to generate very stable DC
and AC outputs from the PMA output.
CURRENT: The maximum allowed current at the specied voltage
and power factor.
PHASE: The number of live wires running from the genverter.
WEIGHT: The net dry weight (approximately) in kg. This is with-
out fuel, oil, cooling liquid, packaging and external installaon
equipment.
CE-MARKING: The “CE” symbol shows that the genverter is
built according to European Community safety regulaons. This
includes the regulaons regarding safety of pleasure cra, elec-
tric safety and electric magnec compability (EMC) and other
relevant direcves. Under the Machinery Direcve, the genverter
is an incomplete machine and can only comply aer installaon;
refer to the Declaraon included in this manual.
Safety is also a maer of installaon, ulizaon and operang
condions. See also 2.1.
It is recommended to consult the manufacturer before changing
a factory seng. If the genverter involved is not new, former
users may have changed the sengs. Check the sengs when
there is any doubt.

aenon.
2�1�3 Scopeofregulaons
When correctly installed and used under normal condions, this
genverter fulls EC safety regulaons. This genverter could be
part of an installaon or could be used in a way that addional
regulaons of the EC or other authories have to be taken into
account. Refer to the declaraon of conformity/incorporaon
included in this manual.
WARNING
In certain situaons, addional measures may be
necessary. Be aware of wet condions, explosion
hazards, etc.
2�1�4 Maintenance & repair
WARNING!
When service has to be carried out while the engine
is running, be aware of moving parts.
If the genverter is switched o during maintenance
and/or repair acvies, it should be secured against
unexpected and unintenonal switching on:
• remove the DDC fuse from the local control panel
• remove the connecons to the baeries
• be sure that third pares cannot reverse the measures
taken.
Use original spare parts only. Always consult the manual before
carrying out maintenance.
2�1�5 Electrical safety
Warning signs indicate parts which could be live.
The alternator output (which is the inverter input)
can be as high as 400 Volt and is very dangerous.
The only way to get access to the high voltage parts
is with the help of tools. Never run the genverter
when there is access to these parts. Touching these
parts may result in electrical shock which will result
in severe personal injury or loss of life.
• Check all wiring at least once a year. Defects, such as loose
connecons, burned cables, etc. must be repaired immedi-
ately.
• Do not work on the electrical system if it is sll connected
to a current source. Only allow changes to your electrical
system to be made by qualied electricians.
• Connecons and protecon must comply with local stan-
dards.
2�1�6 Installaon
WhisperPower genverters are not self-contained and have to
be properly installed. Installaon involves proper venlaon,
safe electric connecons, safe installaon of the starng bat-
tery, proper ng of the cooling system and fuel pipes etc. In
enclosed areas, installaon includes taking measures to outlet
exhaust fumes. Containing carbon monoxide, these are extreme-
ly dangerous. Carbon monoxide (CO) is an invisible and odourless
gas. Inhalaon produces headache, nausea or death. Refer to the
installaon manual.
Do not use the genverter when the vessel is inside a
boat house or in other enclosed areas.
2�1�7 Operaon
WhisperPower genverters have no external moving parts like
fans and V-belts. The fan of the radiator unit is covered by a grid.
The hot parts of the engine are covered by the sound shield and
therefore these genverters are very safe when the sound shield
is closed.

Piccolo Marine Diesel Genverter 2 | 3 | 3+ | 8 | 10 | 12 | 15 | 18 7
Nevertheless take note of the triangular signs on the
genverter indicang danger.
• The genverter should be operated by authorized personnel
only.
• Be aware of hot parts and especially parts of the exhaust
system and the cooling system.
• If the genverter is unsafe, t danger noces and disconnect
the baery posive (+) lead so that it cannot be started unl
the condion is corrected.
• Do not aempt to operate the genverter with a known un-
safe condion. Disconnect the baery posive (+) lead prior
to aempng any repairs or cleaning inside the enclosure.
• Always consult the manual before carrying out mainte-
nance.
• Do not change the sengs without consulng the manufac-
turer. Keep a record of seng changes in this manual.
2�1�8 Fire and explosion
Fuels can be ammable. Proper handling limits the
risk of re and explosion.
WARNING
Never use the genverter in situaons where there is
danger of gas or dust explosion or where potenally
ammable products are present!
• Avoid relling the fuel tank while the engine is running.
When oil or fuel is leaking do not use the genverter.
• Hydrogen gas generated by charging baeries is explosive.
Ensure proper venlaon. Do not smoke and do not allow
sparks, ames, or other sources of ignion around baeries.
• Keep a re exnguisher on hand.
• In case of re, do not open the sound shield. To avoid seri-
ous injury or death from re, shut down engines, generator
sets and blowers. However, if you do open the sound shield,
immediately discharge the enre contents of a portable re
exnguisher into the enclosure.
• Poor electrical connecons or using wiring which is not
suited for the rated currents can cause overheang and pos-
sibly re.
2�1�9 Dangerous substances
Fuels, oils, coolants, and baery electrolyte can be hazardous to
personnel if not handled properly. Do not swallow or have skin
contact with these liquids. Do not wear clothing that has been
contaminated by fuel or lubricang oil.
The gaskets used in the genverter are free of asbestos. However,
gaskets containing asbestos can sll be found. Avoid inhaling
parcles of this material as this may result in fatal diseases.
Therefore it is a good habit to be careful with gaskets.
On no account allow unprotected skin to come into contact with
the injector spray as the fuel may enter the blood stream with
fatal results.
Engines may be ed with seals or O-rings manufactured from
“Viton” or similar material. When exposed to abnormally high
temperatures in excess of 315°C an extremely corrosive acid is
produced which cannot be removed from the skin. If signs of
decomposion of the material are evident, or if in doubt, always
wear heavy duty disposable gloves.
2�1�10 Warningregardinglifesupportapplicaons
The WhisperPower genverters are not intended to be used as a
component of any life support system unless a specic wrien
agreement pertaining to such intended use is executed between
the manufacturer and WhisperPower. Such agreement will
require the medical equipment manufacturer either to contract
addional reliability tesng of the genverter and/or to commit to
undertake such tesng as a part of the manufacturing process.
In addion the medical equipment manufacturer must agree to
indemnify and not hold WhisperPower responsible for any claims
arising from the use of the genverter in the life support equip-
ment.
2�2 TRANSPORT, LIFTING AND STORAGE
When liing the genverter avoid any risk of personal
injuries. In parcular, do not stand under the
genverter.
• Use so slings to avoid damage
• The engine has a liing eye which can be used to take the
genverter out of the enclosure. It can also be used to li the
complete genverter including the enclosure.
• Aer transporng the genverter check for damage before
installaon.
• Long term storage can have detrimental eects on engine
and alternator. The engine should undergo an engine pres-
ervaon procedure (refer to the maintenance chapter.)
• Condensaon may occur on alternator windings. To mini-
mize condensaon, store the genverter in a dry and warm
storage area.
• While the baery is stored it should be recharged every 12
weeks.

2�3 FEATURES
2�3�1 General
The WhisperPower genverters combine carefully selected
engines with highly ecient Permanent Magnet alternators.
The voltages and frequencies produced, however, require the
genverter to be connected to a WhisperPower DC PowerCube
or Power Module producing clean DC or AC output. This is an
original concept, which is cost-eecve as wells as easy on
installaon.
2�3�2 Construcon
The genverter incorporates a diesel engine which has a perma-
nent magnet alternator in the ywheel. The engine is mounted
on a steel base frame and mounted securely on a double set of
an-vibraon mounng pads in a sound aenuated enclosure.
The output of the power from the alternator will be between
300V-400Hz and 400V-500Hz, depending on the engine speed.
The engine speed is set to strike a balance between fuel e-
ciency and comfort. All cables and hoses are guided through the
enclosure’s sides.
2�3�3 Control
The genverter’s control system is based on microprocessor
technology. On models featuring Digital Diesel Control (DDC),
several operang modes and automac start/stop funcons can
be programmed and monitored (refer to Digital Diesel Control
user’s manual).
All funcons can be set from the remote control panel, which
comes as standard with the genverter, including an RJ12 connect-
ing cable.
2�3�4 Installaon
The genverter is not self-contained and is only operable aer
proper installaon using addional accessories and installaon
materials such as a starter baery, fuel supply and an exhaust
system.
Installaon accessories are listed in the installaon manual and
are available through the supplier of the genverter.
2�3�5 Documentaon
Included in the delivery are:
• This user’s manual (no. 40200421)
• An installaon manual (no. 40200701)
• A DDC operang manual (no. 40200801), as applicable
• A DDC quick reference guide (no. 40200142), as applicable
The user’s manual contains a list of important maintenance and
spare parts as well as a chapter on maintenance and problem
solving. Manuals in other languages are available on request.

3 TECHNICAL INFORMATION
3�1 EXPLANATION OF FUNCTIONAL PARTS
WhisperPower genverters are highly advanced systems. They
combine new technologies from various elds such as engine
technology, PM alternator technology and, in the PowerCubes
and Power Modules, inverter technology.
3�1�1 Control system
The standard electrical engine control system is 12 Volt negave
earth. Non-earth return (ungrounded) is available as opon.
Check your idencaon data to determine which system is
being used. Either system is of the “energize to run” type: it stops
when the 12 V DC voltage is taken away.
3�1�2 AC Permanent Magnet Alternator
The Three Phase Permanent Magnet Alternator is incorporated
in the ywheel and has a very high eciency of at least 94%. The
output of the power from the alternator will be between 250V-
300Hz and 400V-500Hz, depending on the engine speed. As the
eciency is very high, lile cooling is needed. The alternator and
the engine use the same cooling system.
WARNING!
The alternator magnets are very powerful. Prevent
drilling chips or metal parts from entering into the
sound shield as these may be drawn into the
alternator and cause the alternator to fail.
WARNING!
The alternator’s magnec eld may cause false
compass readings. This should be taken into account
when installing a compass.
3�1�3 Engine
The genverter has a Kubota engine ne-tuned by WhisperPower.
The engine has indirect injecon and was designed to meet the
highest emission standards. The cooling system can be used for
CHP (Combined Heat and Power producon). Contact Whisper-
Power for addional informaon.
Further details are in the data sheet in 3.2.
3�1�4 Starterbaerycharging
The engine is equipped with a 12.5A (Piccolo 8) or 40A (Piccolo
10) alternator for charging the starter baery. The voltage is
regulated at ±14.4V.
3�1�5 Piccolo PMG control
WP-PMG POWER MODULE GENVERTER (PICCOLO 8)
Through the WP-PMG Power Module Genverter, the user can
control and operate the genverter.
By pushing the START buon on the PMG control panel (refer
to Figure 10) for two seconds, the control system is acvated
and will start the engine automacally. Pushing the STOP buon
(again hold two seconds) will stop the engine and the electrical
system will be deacvated.
Figure 10: WP-PMG control panel (230V model shown)
The various control panels indicate the AC load. As far as PMG
operaon and funconality is concerned, the reader is referred
to the PMG User’s Manual.
3�1�6 Piccolo DDC and Piccolo 10, 12, 15 and 18 control
3.1.6.1 Alarms and shut-down
In the event of malfunconing this will be indicated by the failure
light, details will be shown on the display and the engine will be
shut down. Three parameters are being monitored: oil pressure,
oil temperature and exhaust temperature.
Exhaust temperature too high indicates that the injecon of
cooling water into the exhaust is being blocked .
All alarm switches are closed when no malfuncon occurs. A con-
tact is cut in the event of an alarm. This means that the genverter
will not work when the alarm switches are broken or when there
is a loose wire. The system therefore is intrinsically safe. The
panel will display details about the alarm.
3.1.6.2 Control
The genverter can be operated by push buons on the panel on
the unit or on the remote control. Pushing the START buon will
acvate the control system and will start the engine automacal-
ly. Pushing the STOP buon will stop the engine and the electrical
system will be deacvated. When using the genverter in an
automac mode the engine will start when power is demanded,
e.g. because of low baeries or another “event” that triggers
the starng operaon. Various automac modes are available
through the remote control panel. Refer to the DDC Operang
manual for more informaon.

Figure 11: Local control panel
3.1.6.3 Remote control panel
The remote control panel is used to make the various sengs.
It also displays parameters such as Voltage, Hz, Amps, and many
others (refer to the DDC manual for details).
The connecon between the remote control panel and the
genverter control unit is made using plug-in connectors. A 10 m
communicaon cable is in the standard supply. If necessary, a
longer or shorter cable can be supplied. Mulple remote control
units can be put in parallel by using the connectors on the back
of the units (refer to installaon instrucons).

3�1�7 FuelSpecicaon
The engine must only be used with diesel fuel oil conforming to
the standards for use in modern diesel engines. It is essenal
that the fuel should be free from water and contaminants. The
following specicaons must be complied with:
DieselFuelSpecicaon Locaon
EN590 European Union
Biodiesel: EN 14214
BS 2869-A1 or A2 UK
No. 2-R, No 1-D, ASTM D975-94 USA
Biodiesel: ASTM D-6751
GB252 China
ISO 8217 DMX Internaonal
JIS K2204 Grade No.2 Japan
KSM-2610 South-Korea
Diesel pre-heater
Oponally, a diesel pre-heater can be installed. This is a useful in
extremely cold condions. In this case the fuel lter will be inside
the enclosure and there will be a heang element upstream
of the lter prevenng the formaon of paran crystals in the
diesel and clogged lters as a result. The system’s operaon is
temperature-dependent and is controlled by a separate switch to
turn it “on” or “o”.
3�1�8 Biodiesel
The use of diesel fuels to a maximum blend of 5% (by volume)
of Fay Acid Methyl Esters (FAME) known on the market as B5
diesels is allowed as far as these fuels comply with EN 14214
(Europe) or ASTM D-6751 (USA), as appropriate.
Biofuels should be supplied by recognized and authorized suppli-
ers only. ”Self-blended fuels” may cause engine damage and will
aect warranty.
Please note that free methanol in FAME may result in corrosion
of aluminium parts. Free water in FAME may result in choked fuel
lters and injectors and may result in increased bacterial growth.

3�1�9 Lubricangoil
1 Specicaon:
The oil must be suitable for oil changes as specied in the
maintenance chapter. The engine must be run on heavy duty
lubricang oil meeng the requirements of API class CF, CF-4, CH-
4, CI-4 or CI-4 plus . It is recommended to use lubricang oil from
WhisperPower or a well-known brand.

the fuel should be free from water and contaminants. The follow-
ing specicaons must be complied with:
2 Oil viscosity:
We recommend 10W50 mul grade oil. In very cold or hot
condions, a special grade could be applied according to the
Viscosity Chart below:
Figure 13: Viscosity chart
3 Oil capacity:
The content of the crankcase and oil lter, is as specied below
(approximate data):
Piccolo 2/8 2.1 L
Piccolo 3/10/12 3.2 L
Piccolo 3+/15 4.0 L
Piccolo 18 6.0 L
Do not overll with lubricang oil as this may have a
detrimental eect on engine performance.
4 Lubricangoilpressure:
• Minimum at idle: 49 kPa (0,5 kgf/cm2 - 7psi).
• Normal at 3000 rpm: between 147 and 490 kPa
(1,5 up to 5 kgf/cm2 - 21 up to 71 psi).
• Minimum at 3000 rpm: 98 kPa (1,0 kgf/cm2 - 14 psi).
3�1�10 Cooling liquid
The genverter is cooled by cooling liquid. Use only long-life
type G12+ cooling liquid in order to minimize maintenance. The
capacity of the engine’s cooling system is approximately 3.5
-4.0 litres. When the cooling is based on keel cooling or radiator
cooling the capacity of these coolers and piping has to be taken
into account.
Inially, the engine can be lled via the lling cap on the exhaust
manifold. Fill up ll the level is just below the lling cap. Filling
of the alternator cooling system and addional lling of engine
cooling system has to be done via the expansion tank. When the
engine is on temperature the liquid will expand and the redun-
dant liquid will be pressed into the expansion tank. This tank has
to be lled up ll the mark.

4�4 OPERATING INSTRUCTIONS
4�4�1 Daily check of oil level
Be sure to keep the oil level between upper and lower limits
of the oil gauge. Too much oil may cause a drop in output or
excessive blow-by gas, while too lile oil may seize the engine’s
rotang and sliding parts.
Procedure:
1. Check the engine oil level before starng or more than 5
minutes aer stopping the engine.
2. Remove the oil dipsck, wipe it clean and reinsert it. Take
the dipsck out again, check the oil level gauge and reinsert
the dipsck.

5. Before loading the generang set up to its maximum, have
it run warm. Connuous load should be restricted to 70 %
of maximum load.
Stopping the genverter:
1. If the genverter has been running under full load for a
longer period, do not shut it down abruptly. Reduce the
electrical load to about 30% of the rated load and let it run
for around 5 min.
2. Press the STOP buon and hold for one (DDC) or two
(PMG) seconds.
3. Close the inlet sea water valve.
4. Switch to another AC power source, if available.

rest:
1. If there is any damage caused by transport or installaon.
2. Check if the installaon conforms to the installaon instruc-
ons.
3. Ensure the engine is free to turn without obstrucon.
4. Check all hoses and hose connecons for leaks.
5. Check all cables and terminal connecons.
Roune“pre-start”checks:
1. Check engine oil level. The genverter switches o in the
event of insucient oil pressure. Even when the oil level is
too low, the oil pressure can be high enough not to trip an
alarm. Do not run the engine with the oil below the lowest
mark, because a smaller volume of oil will become contami-
nated considerably quicker than a larger volume. Moreover,
a low level may aect cooling. Therefore, we recommend
daily oil-checks. Check oil level prior to starng the engine
or at least 5 minutes aer the engine has stopped.
2. Check for leakages.
3. Switch o all devices.
4. Switch on the baery switch (if installed).
Starngthegenverter:
By pushing the start buon and holding it for one (DDC) or two
(PMG) seconds, the electric system is acvated. You can monitor
the procedure on the display of the remote control panel. First,
the fuel pump will prime the fuel for a few seconds (seable); the
starter will then crank the engine unl it starts. While starng the
alarms are blocked (this is achieved by pushing the Start buon).
The alarms are reacvated aer 10 seconds.
Warm up the engine without load for 3 minutes. A restart pro-
tecon prevents cranking the engine when it is already running,
which could cause damage.
Never use ether or gasoline to facilitate a cold start
as it could damage the engine.
Checksoncetheengineisinoperaon:
1 Check for abnormal noise or vibraon.
2 Check the output parameters on the remote control display.
3 Observe the exhaust at the rated load.
The exhaust must be free from soot. Do not allow the engine to
run with visible smoke from the exhaust without invesgang the
cause, as this may result in an expensive breakdown.
Engineloadduringlongeroperaon:
During the rst 50 hours of running, the connuous load should
be restricted to 70 % of the maximum load. Running at no load or
light load for long periods in the rst 50 hours may cause cylinder
glazing and high oil consumpon.
Avoid overloading the genverter. Overloading occurs when the
electrical load (demand) is so high that by the diesel engine has
trouble driving the alternator. It causes the engine to run rough,
while using oil and excessive fuel and producing soot. The engine
may even stop. The genverter should therefore be loaded at the
maximum rated power for short periods (2-3 hours) only! The
high peak current is meant for the ability to start electrical devic-
es that need a high current for starng especially electric motors
and compressors (from a sll stand state).
In order to prolong the genverter’s life expectancy, the nominal
electrical demand of the system should not exceed 70% or the
genverter’s rated maximum load. Please note this when switch-
ing on your electrical equipment! Nevertheless, the genverter is
designed so as not to overheat, even under extreme condions.
Do not run the genverter for very long periods at no load or at
very low load. When this is necessary, increase the load to at
least 70% for one hour in 10 hours. Long term running at too low
load will cause the exhaust to be choked by carbon (soot).
Neither remove the baery while the engine is
running nor remove any electrical cable while the
baery is connected to the circuit. Only disconnect
the baery with the engine stopped and all switches
in “OFF” posion.
Stopping the genverter:
1. Avoid stopping the genverter abruptly aer a long period of
operaon at high load. Prior to switching o the genverter,
decrease the load (i.e. turn o most electrical consumers)
and let the genverter run at low load for approx. 5 minutes
to allow the engine to cool down suciently. Another
reason to switch o electrical consumers prior to stopping
the genverter is the voltage drop that occurs as the engine
comes to a halt.
If the genverter is operang in a hot environment and is not
allowed to cool down, excessive heat in the engine may trip
the “high temperature” alarms. This will prevent restarng
of the engine for some me.
2. Press the STOP buon for one (DDC) or two (PMG) seconds.
3. Switch to another 230V power source, if available.
If the engine is not running and the ‘failure’ and
‘charging’ LEDs are blinking, press the stop buon in
order to prevent the starter baery from being
drained.

The alternator does not require maintenance.
5�3 ENGINE
5�3�1 Preliminaryinstrucons
The rst service on the engine should be carried out aer 50
running hours. This period also applies aer a major overhaul.
During the rst 50 hours, the engine should receive special
aenon:
• Long periods of light or no load running in the rst 50 hours
may lead to cylinder glazing and high oil consumpon.
• For the same reason it is of the greatest importance to use
the right oil specicaon.
5�3�2 Bleeding the fuel lines
When the engine is started up for the rst me or aer it has
run out of fuel, the fuel system may need to be primed. Push the
start buon acvang the electric system and acvang the fuel
pump. When more me is needed to bleed, hold the “Start/Stop”
buon on the local control panel (so not on the remote panel).
While the buon is held, the pump will work, but the unit will not
start. Hold as long as necessary to bleed the system
5�4 REGULAR MAINTENANCE
5�4�1  Generalprecauons
All regular maintenance can be carried out when the enclosure
is open. When oil and dirt have gathered in the enclosure, mea-
sures have to be taken to prevent oil from being spilled.

Piccolo Marine Diesel Genverter 2 | 3 | 3+ | 8 | 10 | 12 | 15 | 18 19
CAUTION!
Riskofpersonalinjury,reand/orelectricshock
• Be sure to conduct daily checks, periodic maintenance,
refuelling or cleaning on a level surface with the engine shut
o and the control system fuse removed.
• Do not touch muer or exhaust pipes while they are hot;
Severe burns could result.
• Allow the engine to cool down suciently, especially before
changing the oil or the oil lter cartridge. Oil can be hot and
cause burns.
• Contact with engine oil can damage your skin. Put on gloves
when using engine oil. If you come in contact with engine
oil, wash it o immediately.
• When changing engine oil, dispose it according to local
regulaons.
• When cleaning any parts, do not use gasoline but use regu-
lar cleanser.
• Always use proper tools, that are in good condion. Make
sure you understand how to use them, before performing
any service work.
• Be sure to ghten all bolts lest they should be loose. Tighten
the bolts by the specied torque.
• Do not put any tools on the baery, or baery terminals
may short out. Severe burns or re could result. Detach the
baery from the engine before maintenance.
5�4�2 Servicingaerbreak-in
• Change engine oil and replace the oil lter (refer to 5.4.3).
• Check and ghten nuts, bolts, and unions, paying parcular
aenon to the fuel system and using the torque chart
below.
Standard torque chart
Size M6x1.0 M8x1.25 M10x1.5
Nm* 10.8+1.0 25.5+2.9 49.0+4.9
* Apply 80% torque when ghtening bolts to aluminium alloy.
• Observe the exhaust at the normal full load. The exhaust
must be free from soot. Do not allow the engine to run with
a dirty exhaust without invesgang the cause as this may
result in an expensive breakdown. When ramping up RPM
the engine will probably produce some smoke. Aer stabiliz-
ing on the right RPM for the load the exhaust should be free
from soot.
• Check the electrical connecons.
5�4�3 Changingengineoilandoilltercartridge
1. Run the engine unl it is on temperature, stop it and let it
cool down suciently to allow safe working.
2. Drain oil through the dipsck hole using a vacuum pump as
commonly used in garages.
3. Put some ssues under the oil lter cartridge.
4. Remove the old cartridge with a lter wrench.
5. Apply a lm of oil to the gasket for the new cartridge.
6. Screw in the cartridge by hand. When the gasket contacts
the seal surface, ghten the cartridge not too rmly, by
hand.
7. Remove the oil ller cap on top of the engine, rell the en-
gine with oil (refer to 3.1.9 for specicaons and quanty).
Allow the oil to come down to the oil pan and check the oil
level.
.8 The oil level should be as close as possible to the maximum
level. Add (or drain) oil as necessary.
NOTE: When the genverter runs less than 200 hours a year, the
oil should be changed yearly.
5�4�4 Checkingthebaery
• Check baery terminals for corrosion
• Check the baery acid level (not applicable when sealed
baeries are used).
5�4�5 AdjusngtheV-belttension
Before adjusng belt tension, inspect the belt for glazing, cracks,
or dryness. A worn or damaged belt should be replaced.
1. Apply moderate thumb pressure to the belt between the
pulleys. When the belt is pressed in the middle of the span,
the deecon should be between 7 mm and 9 mm.
2. If the tension is incorrect, loosen the alternator mounng
bolts and, using a lever placed between the alternator and
the engine block, pull the alternator out unl the deecon
of the belt falls within acceptable limits, then ghten the
alternator mounng bolts.

5�4�6 Draining water from the fuel tank
When handling fuel, make sure there are no open
ames or other re hazards near the engine. Wipe o
any spilled fuel completely. Spilled fuel can ignite and
cause re.
If fuel gets mixed with parcles of foreign maer such as dust,
dirt, or water, it can cause not only a decrease of output but also
malfuncons of the fuel system. To avoid such problems, drain
fuel tank as described below.
1. Posion an oil pan (capacity of 2 litres or more) under the
drain cock of fuel tank.
2. Open the drain cock of fuel tank and drain at least 1 or 2
litres of fuel.
3. Make sure that all water and parcles of foreign maer are
discharged with the fuel. Close the drain cock.
Figure 18: Draining water from fuel tank
5�4�7 Replacing the raw water pump impeller
Both the impeller and the gasket between the pump case and
the cover should be replaced. So when ordering the impeller, or-
der a gasket, too (see Secon 7, Spare parts). Remove the cover
to get access to the impeller. Remove the old impeller with the
help of two screwdrivers. Install the new impeller and add some
grease. Turn the blades in the direcon of rotaon of the pump
i.e. an-clockwise looking at the impeller.
On M-GV 8 Piccolo genverters, the pump housing needs to be
taken from the engine in order to gain access to the cover. This is
achieved by removing the bolts shown in Figure 19. Remount the
pump aer changing the impeller.
Figure 19: Pump housing: bolts to be unscrewed
5�4�8 Replacingthefuellter
Filter change depends on the level of contaminaon of the fuel,
but should be done at least every 400 running hours. A clogged
lter results in a lack of output of the engine and irregular
running. Before changing the lter, clamp o the supply line. The
arrow on the lter housings indicates the ow direcon. Remove
the hoses from the old lter and t the new lter.
Figure 20: Fuel lter (similar on all models)
5�4�9 Changingtheairlterelement
The genverter is standard supplied with an air inlet lter element.
Filter change depends on air quality.
Procedure:
1. Unscrew the cover in order to gain access to the lter.
2. Clean the foam around the element with compressed air
and clean the strainer element.
3. Check the air lter and replace it when necessary (do not
clean the air lter element).
4. Put back the cover and reghten the screws.
5�4�10 Checkinghosesandelectricalconnecons
Visually check cooling hoses, fuel hoses and electrical wiring,
paying parcular aenon to abrasion, wear and corrosion. Have
items replaced when necessary.
