GENERAL INFORMATION
6 Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN
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 Elite Genverter is switched off during maintenance and/or
repair activities, it should be secured against unexpected and
unintentional switching on:
• remove the AC supply;
• remove the connection to the batteries;
• be sure that third parties cannot reverse the
measures taken.
If maintenance and repairs are required, 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.
• Check all wiring at least once a year. Defects, such as
loose connections, burned cables etc. must be
repaired immediately.
• Do not work on the electrical system if it is still
connected to a current source. Only allow changes in
your electrical system to be carried out by qualified
electricians.
• Connection and protection must be done in
accordance with local standards.
2.1.6 Magnetism
WARNING!
The genverter incorporates powerful permanent
magnets. Cardiac patients, especially those living
with a pacemaker, should bear this in mind.
2.1.7 Operation
There are no external moving parts like fans and V-belts. The hot
parts of the engine are covered by the sound shield and
therefore the Elite Genverter is very safe when the sound shield
is closed.
Nevertheless take note of the signs on the Genverter which show
symbols in a triangle indicating 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, fit danger notices and
disconnect the battery positive (+) lead so that it
cannot be started until the condition is corrected.
• Do not attempt to operate the Genverter with a
known unsafe condition. Disconnect the battery
positive (+) lead prior to attempting any repairs or
cleaning inside the enclosure.
• Always consult the manual before carrying out
maintenance.
• Do not change the settings without consulting the
manufacturer. Keep a record of setting changes in this
manual.
2.1.8 Fire and explosion
Fuels can be flammable. Proper handling limits the risk of fire and
explosion.
WARNING
Never use the Elite Genverter in situations where
there is danger of gas or dust explosion or
potentially flammable products!
• Avoid refilling the fuel tank while the engine is
running. When oil or fuel is leaking do not use the
Elite Genverter.
• Hydrogen gas possibly generated by batteries being
charged is explosive. Ensure proper ventilation. Do
not smoke or allow sparks, flames, or other sources of
ignition around batteries.
• Keep a fire extinguisher on hand.
2.1.9 Chemicals
• Fuels, oils, coolants, and battery electrolyte can be
hazardous if not treated properly. Do not swallow or
have skin contact with these liquids. Do not wear
clothing that has been contaminated by fuel or
lubricating oil.
• On no account allow any unprotected skin to come
into contact with the injector spray as the fuel may
enter the blood stream with fatal results.
• Engines may be fitted with seals or O-rings
manufactured from "Viton" or similar material. When
exposed to abnormal high temperatures in excess of
400°C an extremely corrosive acid is produced which
cannot be removed from the skin. If signs of
decomposition are evident, or if in doubt, always
wear disposable heavy duty gloves.
2.2 TRANSPORT, LIFTING AND STORAGE
When lifting the Genverter avoid any risk of personal injuries, do
not stand under the Genverter.
• Use soft slings to avoid damage
• On the engine is a lifting hoist eye which can be used
to take the Genverter out of the capsule. It can also
be used to lift the complete Genverter including the
capsule.

GENERAL INFORMATION
Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN 7
• After transporting the Genverter check for damage
before installation.
• Long term storage can have detrimental effects on
engine and alternator. The engine should be put
through an engine preservation procedure. (Refer to
the maintenance chapter).
• The alternator windings tend to condense. To
minimize condensation, store the Genverter in a dry
and warm storage area.
• Follow the battery manufacturer’s instructions when
storing the battery.
2.3 FEATURES
2.3.1 General
The WhisperPower two and three cylinder Genverters combine
2 and 3 cylinder engines with highly efficient Permanent Magnet
alternators. The voltages and frequencies produced, however,
require Genverters to be connected to WhisperPower
PowerCubes or Power Modules producing clean DC or AC output,
as applicable. This is an original concept, which is cost-effective
as wells as easy on installation.
2.3.2 Construction
The Genverter incorporates a diesel engine which has a
permanent magnet alternator in the flywheel. The engine is
mounted on a steel base frame and mounted securely on a
double set of anti-vibration mounting pads in a sound attenuated
canopy. The output of the power from the alternator will be from
zero to 300V-400Hz and 400V-500Hz, depending on the engine
speed. The engine speed is set to strike a balance between fuel
efficiency and comfort. All cables and hoses are guided through
the capsule’s sides.
2.3.3 Control
The Digital Control system of the Genverter is based on
microprocessor technology. Several operating modes and
automatic start/stop functions can be programmed and
monitored (refer to Digital Diesel Control user’s manual).
All functions can be set from the remote control panel, which
comes as standard with the Genverter, including a 15 m cable.
2.3.4 Installation
The Genverter is not self-contained and is only operable after
proper installation using additional accessories and installation
materials such as a starter battery, fuel supply and an exhaust
system.
Installation accessories are listed in the installation manual and
are available through the supplier of the Genverter.
2.3.5 Documentation
Included in the delivery are:
• This user’s manual.
• An installation manual.
• A DDC operating manual.
• A DDC quick reference guide.
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.

TECHNICAL INFORMATION
Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN 12
3 TECHNICAL INFORMATION
3.1 EXPLANATION OF FUNCTIONAL PARTS
The WhisperPower two and three cylinder Genverters are highly
advanced systems. They combine new technologies from various
fields such as engine technology, PM alternator technology and,
in the PowerCubes and Power Modules, inverter technology.
3.1.1 Control system
The engine is monitored and controlled by microprocessors in
the Digital Diesel Control system (DDC). The standard electrical
engine control system is 12 Volt negative earth. Non-earth return
(ungrounded) is available as option. Check your identification
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. Highly advanced, the DDC controls the engine and
also operates as a management system to control the engine in
combination with the PowerCube.
3.1.2 AC Permanent Magnet Alternator
The Three Phase Permanent Magnet Alternator is incorporated
in the flywheel and has a very high efficiency 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
efficiency is very high, little cooling is needed. The alternator and
the engine use the same cooling system.
3.1.3 Engine
The Genverter has a Kubota engine fine-tuned by WhisperPower.
The engine has indirect injection and was designed to meet the
highest emission standards. The cooling system can be used for
CHP (Combined Heat and Power production). Contact
WhisperPower for additional information.
Further details are in the data sheet in 3.2.
3.1.4 Starter battery charging
The engine is equipped with a 12.5A (two-cylinder version) or
40A (three-cylinder version) alternator for charging the starter
battery. The voltage is regulated at ±14.4V.
3.1.5 Alarms and shut-down
In the event of malfunctioning this will be indicated by the failure
light, details will be shown on the display and the engine will be
shut down. Two parameters are being monitored: oil pressure
and oil temperature.
All alarm switches are closed when no malfunction occur. A
contact 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 Control
The Genverter can be operated by push buttons on the panel on
the unit or on the remote control. Pushing the START button will
activate the control system and will start the engine
automatically. Pushing the STOP button will stop the engine and
the electrical system will be deactivated. When using the
Genverter in an automatic mode the engine will start when
power is demanded, e.g. because of low batteries or another
“event” that triggers the starting operation. Various automatic
modes are available through the remote control panel. Refer to
the DDC Operating manual for more information.
Figure 7: Local control panel
3.1.7 Remote control panel
The remote control panel is used to make the various settings. It
also displays parameters such as Voltage, Hz, Amps, and many
others (refer to the DDC manual for details).
The connection between the remote control panel and the
Genverter control unit is made using plug-in connectors. A 10 m
communication cable is in the standard supply. If necessary, a
longer or shorter cable can be supplied. Multiple remote control
units can be put in parallel by using the connectors on the back
of the units (refer to installation instructions).

TECHNICAL INFORMATION
Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN 13
3.1.9 Fuel
Specification
The engine must only be used with diesel fuel oil conforming to
the standards for use in modern diesel engines. It is essential that
the fuel should be free from water and contaminants. The
following specifications must be complied with:
Diesel Fuel Specification
Location
EN590:96
European Union
BS 2869-A1 0r A2
UK
No. 2-R, No 1-D, ASTM D975-94
USA
GB252
China
ISO 8217 DMX
International
JIS K2204 Grade No.2
Japan
KSM-2610
South-Korea
Diesel pre-heater
Optionally, a diesel pre-heater can be installed. This is a useful
feature in extremely cold conditions. In this case the fuel filter
will be inside the canopy and there will be a heating element
upstream of the filter preventing the formation of paraffin
crystals in the diesel and clogged filters as a result. The system’s
operation is temperature-dependent and is controlled by a
separate switch to turn it “on” or “off”.
3.1.10 Bio-diesel
The use of diesel fuels to a maximum blend of 5% (by volume) of
Fatty 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.
Bio-fuels should be supplied by recognized and authorized
suppliers only. ”Self-blended fuels” may cause engine damage
and will affect warranty.
Please note that free methanol in FAME may result in corrosion
of aluminium parts. Free water in FAME may result in choked fuel
filters and injectors and may result in increased bacterial growth.
3.1.11 Lubricating oil
1 Specification:
The oil must be suitable for oil changes as specified in the
maintenance chapter. The engine must be run on heavy duty
lubricating oil meeting the requirements of API class CF, CF-4,
CH-4, CI-4 or CI-4 plus . It is recommended to use lubricating oil
from WhisperPower or a well-known brand.
It is very important to use the correct oil
specification. Do not mix different types of oil.
Higher API class oils and synthetic oils are to be
avoided.
2 Oil viscosity:
We recommend 15W40 multi grade oil. In very cold or hot
conditions, a special grade could be applied according to the
Viscosity Chart below:
Figure 8: Viscosity chart
3 Oil capacity:
The content of the crankcase and oil filter, is as specified below
(approximate data):
Elite 8 Kubota
2.1 L
Elite 10, 12 Kubota
3.2 L
Elite 15 Kubota
4.0 L
Do not overfill with lubricating oil as this may have
a detrimental effect on engine performance.
4 Lubricating 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).
3.1.12 Cooling liquid
The engine 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
litres. The capacities of the radiator and piping have to be taken
into account as well.
Initially, the engine can be filled via the filling cap on the exhaust
manifold. Fill up till the level is just below the filling cap. Filling of
the alternator cooling system and additional filling of engine
cooling system has to be done via the expansion tank. When the
engine is on temperature the liquid will expand and the
redundant liquid will be pressed into the expansion tank. This
tank has to be filled up till the mark. The tank has an overflow
connection, which can be used to connect an open hose to drain
the overflow of the cooling liquid to outside the vehicle.

OPERATION
16 Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN
4 OPERATION
4.1 GENERAL
The genverter is operational after full installation and filling up
with fuel, engine lubricating oil and cooling liquid, connecting the
battery and connecting the digital remote control panel.
4.2 PROGRAMMABLE SPEED
At the time of commissioning, the engine rpm are set to meet
the output requirements of the installation.
4.3 OPERATING INSTRUCTIONS
4.3.1 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 little oil may seize the engine's
rotating and sliding parts.
Procedure:
1 Check the engine oil level before starting or more than 5
minutes after stopping the engine.
2 Remove the oil dipstick, wipe it clean and reinsert it.
Take the dipstick out again, check the oil level gauge and
reinsert the dipstick.
Figure 10: Oil dipstick (similar on all models)
3 If the oil level is too low, remove the oil filler plug, and add
new oil to the prescribed level.
4 After adding oil, allow the oil to come down to the oil pan
before checking the oil level again.
4.3.2 Summarized operating instructions (daily use)
Routine "pre-start" checks:
1 Check oil level and cooling liquid level.
2 For systems incorporating PMG: power source selector
switch (off/shore power/generator power) in “off” position,
or switch of all consumers in the usual way. If a Whisper
Switch of Transfer System Switch is installed, this operates
automatically.
3 Switch on battery switch (if installed).
4 Fuel valve: open.
Starting:
Push the start button and hold for a second to initiate the fully
automatic starting procedure.
In operation checks:
1 Check for abnormal noise or vibration
2 Check the output parameters on the remote control display
3 For systems incorporating PMG: switch power source
selector to “generator” position. If a Whisper Switch of
Transfer System Switch is installed, this operates
automatically.
4 Before loading the generating set up to its maximum, have
it run warm. Continuous 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 button.
3 Switch to another AC power source, if available
4.3.3 Extended operating instructions
Check when starting the first time or after a longer period of rest:
1 If there is any damage caused by transport or installation.
2 Check if the installation conforms to the installation
instructions.
3 Ensure the engine is free to turn without obstruction.
4 Check all hoses and hose connections for leaks.
5 Check all cables and terminal connections.
Routine "pre-start" checks:
1 Check engine oil level. The genverter switches off in the
event of insufficient 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
contaminated considerably quicker than a larger volume.
Moreover, a low level may affect cooling. Therefore, we
recommend daily oil-checks. Check oil level prior to starting
the engine or at least 5 minutes after the engine has
stopped.
2 Check for leakages.
3 Switch off all devices.
4 Switch on the battery switch (when installed).
Starting the genverter:
By pushing the start button and holding it for a second, the
electric system is activated. 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 (settable); the
starter will then crank the engine until it starts. While
starting the alarms are blocked (this is achieved by pushing
A

OPERATION
Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN 17
the Start/Stop button). The alarms are reactivated after 10
seconds.
Warm up the engine without load for 3 minutes. A restart
protection 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 operation:
1 Check for abnormal noise or vibration.
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
investigating the cause, as this may result in an expensive
breakdown.
Engine load during longer operation:
During the first 50 hours of running, the continuous load
should be restricted to 70 % of the maximum load. Running
at no load or light load for long periods in the first 50 hours
may cause cylinder glazing and high oil consumption.
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 devices that need a
high current for starting especially electric motors and
compressors (from a still 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 switching on your electrical equipment!
Nevertheless, the genverter is designed so as not to
overheat, even under extreme conditions.
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 battery while the engine is
running nor remove any electrical cable while the
battery is connected to the circuit. Only
disconnect the battery with the engine stopped
and all switches in "OFF" position.
Stopping the genverter:
1 Avoid stopping the genverter abruptly after a long period of
operation at high load. Prior to switching off the genverter,
decrease the load (i.e. turn off most electrical consumers)
and let the genverter run at low load for approx. 5 minutes
to allow the engine to cool down sufficiently. Another
reason to switch off electrical consumers prior to stopping
the genverter is the voltage drop that occurs as the engine
comes to a halt.
If the genverter is operating 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 restarting
of the engine for some time.
2 Press the STOP button.
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 button
in order to prevent the starter battery from being
drained.

5.2 ALTERNATOR
The alternator does not require maintenance.
5.3 ENGINE
5.3.1 Preliminary instructions
The first service on the engine should be carried out after 50
running hours. This period also applies after a major overhaul.
During the first 50 hours, the engine should receive special
attention:
• Long periods of light or no load running in the first 50 hours
may lead to cylinder glazing and high oil consumption.
• For the same reason it is of the greatest importance to use
the right oil specification.
5.3.2 Bleeding the fuel lines
When the engine is started up for the first time or after it has run
out of fuel, the fuel system may need to be primed. Push the start
button activating the electric system and activating the fuel
pump. When more time is needed to bleed, hold the “Start/Stop”
button on the local control panel (so not on the remote panel).
While the button 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 precautions
All regular maintenance can be carried out when the enclosure
is open. When oil and dirt have gathered in the enclosure,
measures have to be taken to prevent oil from being spilled.
CAUTION!
Risk of personal injury, fire and/or electric shock
• Be sure to conduct daily checks, periodic maintenance,
refuelling or cleaning on a level surface with the engine shut
off and the control system fuse removed.

MAINTENANCE
Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN 19
• Do not touch muffler or exhaust pipes while they are hot;
Severe burns could result.
• Allow the engine to cool down sufficiently, especially before
changing the oil or the oil filter 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 off immediately.
• When changing engine oil, dispose it according to local
regulations.
• When cleaning any parts, do not use gasoline but use
regular cleanser.
• Always use proper tools, that are in good condition. Make
sure you understand how to use them, before performing
any service work.
• Be sure to tighten all bolts lest they should be loose. Tighten
the bolts by the specified torque.
• Do not put any tools on the battery, or battery terminals
may short out. Severe burns or fire could result. Detach the
battery from the engine before maintenance.
5.4.2 Servicing after break-in
• Change engine oil and replace the oil filter (refer to 5.4.3).
• Check and tighten nuts, bolts, and unions, paying particular
attention to the fuel system and using the torque chart
below.

* Apply 80% torque when tightening 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 investigating the cause as this may
result in an expensive breakdown. When ramping up RPM
the engine will probably produce some smoke. After
stabilizing on the right RPM for the load the exhaust should
be free from soot.
• Check the electrical connections.
5.4.3 Changing engine oil and oil filter cartridge
1 Run the engine until it is on temperature, stop it and let it
cool down sufficiently to allow safe working.
2 Drain oil through the dipstick hole using a vacuum pump as
commonly used in garages.
3 Put some tissues under the oil filter cartridge.
4 Remove the old cartridge with a filter wrench.
5 Apply a film of oil to the gasket for the new cartridge.
6 Screw in the cartridge by hand. When the gasket contacts
the seal surface, tighten the cartridge not too firmly, by
hand.
7 Remove the oil filler cap on top of the engine, refill the
engine with oil (refer to 3.1.11 for specifications and
quantity). 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 battery
• Check battery terminals for corrosion
• Check the battery acid level (not applicable when sealed
batteries are used).
5.4.5 Adjusting the V-belt tension
Before adjusting 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 deflection should be between 7 mm and 9 mm.
2 If the tension is incorrect, loosen the alternator mounting
bolts and, using a lever placed between the alternator and
the engine block, pull the alternator out until the deflection
of the belt falls within acceptable limits, then tighten the
alternator mounting bolts.

5.4.6 Draining water from the fuel tank
NOTE:
This procedure is unusual on mobile installations.
It is included for completeness.
When handling fuel, make sure there are no open
flames or other fire hazards near the engine. Wipe
off any spilled fuel completely. Spilled fuel can
ignite and cause fire.

MAINTENANCE
20 Elite GV 2, 3, 3+, 8, 10 and Elite GV 15 — June 2020 — EN
If fuel gets mixed with particles of foreign matter such as dust,
dirt, or water, it can cause not only a decrease of output but also
malfunctions of the fuel system. To avoid such problems, drain
fuel tank as described below.
1. Position 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 particles of foreign matter are
discharged with the fuel. Close the drain cock.
Figure 11 : Draining water from fuel tank
5.4.7 Replacing the fuel filter
Filter change depends on the level of contamination of the fuel,
but should be done at least every 400 running hours. A clogged
filter results in a lack of output of the engine and irregular
running. Before changing the filter, clamp off the supply line. The
arrow on the filter housings indicates the flow direction. Remove
the hoses from the old filter and fit the new filter.
Figure 13: Fuel filter (similar on all models)
5.4.8 Changing the air filter element
The genverter is standard supplied with an air inlet filter
element. Filter change depends on air quality.
Procedure:
1. Unscrew the cover in order to gain access to the filter.
2. Clean the foam around the element with compressed air
and clean the strainer element.
3. Check the air filter and replace it when necessary (do not
clean the air filter element).
4. Put back the cover and retighten the screws.
5.4.9 Checking hoses and electrical connections
Visually check cooling hoses, fuel hoses and electrical wiring,
paying particular attention to abrasion, wear and corrosion.
Have items replaced when necessary.
5.4.10 Servicing after 800 hours and beyond
This includes the items described above, but also procedures
requiring a professional diesel mechanic. Contact your
WhisperPower Service Centre. Please find some essential data
for Kubota-based genverters below:
‒ Valve clearance: from 0.145 mm to 0.185 mm when the
engine is cold.
‒ Rocker arm bracket nut M6 × 1: from 9.81 nm to 11.2 Nm
‒ Cylinder head screw M8 × 1.25: from 38 Nm to 42 Nm.
5.5 PUTTING OUT OF SERVICE
When not using the genverter for a longer period it is
recommended to perform an engine preservation procedure.
1. Clean the engine.
2. Loosen the fuel suction pipe and fuel return and put them
in a can with preservation diesel fuel.
3. Run the engine until it is on temperature, stop it and let it
cool down sufficiently to allow safe working.
4. Drain the hot engine oil and refill with preservation oil.
5. Disconnect the battery and store it in a dry place free of
frost and charge it regularly.
6. Close inlet and outlet openings with tape.
7. Protect the genverter against the influences of bad weather
conditions.
This method of preservation will be sufficient for 6 months.
Change oil before using the engine again.
