WHAT TO DO IN AN EMERGENCY
Any user of the Engine who follows the instructions
set out in this manual, and complies with the
instructions on the labels affixed to the engine are
working in safe conditions.
If operating mistakes cause accidents call for help
If operating mistakes cause accidents call for help
immediately from the EMERGENCY SERVICES.
In the event of an emergency, and while awaiting the
arrival of the EMERGENCY SERVICES, the
following general advice is given for the provision of
first aid.
FIRE

5
Put out the fire using extinguishers recommended by
the manufacturer of the machine or the installation.
BURNS
1) Put out the flames on the clothing of the
burns victim by means of:
drenching with water
use of powder extinguisher, making
sure not to direct the jets onto the
face
blankets or rolling the victim on the
ground
2) Do not pull off strips of clothing that are
sticking to the skin.
3) In the case of scalding with liquids, remove
the soaked clothing quickly but carefully.
4) Cover the burn with a special anti-burn
packet or with a sterile bandage.
CARBON MONOXIDE POISONING (CO)
Carbon monoxide contained in engine exhaust gases
is odorless and dangerous because it is poisonous and
with air, it forms an explosive mixture.
Carbon monoxide is very dangerous in enclosed
premises because it can reach a critical concentration
in a short time.
When attending a person suffering from CO
poisoning in enclosed premises, ventilate the
premises immediately to reduce the gas
concentration.
When accessing the premises, the person providing
the aid must hold his breath, not light flames, turn on
lights or activate electric bells or telephones so as to
avoid explosions.
Take the victim to a ventilated area or into the open
air, placing him on his side if he is unconscious.
CAUSTIC BURNS
1) Caustic burns to the skin are caused by acid
escaping from the batteries:
remove the clothes
wash with running water, being
careful not to affect injury-free areas.
2) Caustic burns to the eyes are caused by
battery acid, lubricating oil and diesel fuel.
Wash the eye with running water for
at least 20 minutes, keeping the
eyelids open so that the water runs
over the eyeball and moving the eye
in all directions.
ELECTROCUTION
Electrocution can be caused by:
1) The engine’s electrical system (12/24
VDC)
2) The electrical coolant pre-heating system
120/240 Volt AC (if supplied) AC current.
In the first case, the low voltage does not involve
high current flows through the human body;
however, if there is a short circuit, caused by a metal
tool, sparks and burns may occur.
In the second case, the high voltage causes strong
currents, which can be dangerous.
If this happens, break the current by operating the
switch before touching the injured person.
If this is not possible, bear in mind that any other
attempt is highly dangerous also for the person
assisting; therefore, any attempt to help the victim
must be carried out without fail using means that are
insulating.
WOUNDS AND FRACTURES
The wide range of possible injuries and the specific
nature of the help needed means that the medical
services must be called.
If the person is bleeding, compress the wound
externally until help arrives.
In the case of fracture do not move the part of the
body affected by the fracture. When moving an
injured person permission from that person must be
received until you can help him. Unless the injury is
life threatening, move the injured person with
extreme care and then only if strictly necessary.
WARNING LABELS
Warning labels, in picture form, are applied to the
engine. Their meanings are given below.
Important Note: Labels that show an exclamation
mark indicate that there is a possibility of danger.

2.2 ENGINE STORAGE
2.2.1 Storage less than 1 year
Storing engines requires special attention. Clarke
engines, as prepared for shipment, may be stored for
a minimum of one year. During this period, they
should be stored indoors in a dry environment.
Protective coverings are recommended provided they
are arranged to allow for air circulation. The stored
engine should be inspected periodically for obvious
conditions such as standing water, part theft, excess

7
dirt buildup or any other condition that may be
detrimental to the engine or components. Any such
conditions found must be corrected immediately.
2.2.2 Extended Storage Maintenance Procedure
After a one year storage period or if the engine is
being taken out of service for more than 6 months,
additional preservation service must be performed as
follows:
1) Drain the engine oil and change the oil filter.
2) Refill the engine crankcase with MIL-L-
21260 preservative oil.
3) Change the fuel filter.
4) Remove the protection from the intake and
exhaust openings.
5) Prepare a container as a fuel source using a
mixture of Mobilarma or Sta-Bil with Diesel
#2 fuel or “Red” diesel fuel (ASTM D-975)
or BS2869 Class A2.
6) Disconnect the coupling or drive shaft from
the pump.
7) Start and run the engine at a slow speed for
1-2 minutes being careful not to exceed the
normal operating temperature.
8) Drain the oil.
9) Replace the protective plugs that were used
for shipping and storage.
10) Attach to the engine a visible card, specifying
“ENGINE WITHOUT OIL” DO NOT
OPERATE”.
IMPORTANT: THIS TREATMENT MUST BE
REPEATED EVERY 6 MONTHS
************************
PUTTING ENGINE INTO SERVICE AFTER
ADDITIONAL PRESERVATION SERVICE:
To restore the normal operation running conditions of
the engine, carry out the following:
1) Fill the engine sump with the normal
recommended oil, to the required level.
2) Remove the protective plugs used for
shipping and storage.
3) Remove the card “ENGINE WITHOUT OIL,
DO NOT OPERATE”.
4) Follow all steps of the Installation
Instructions when the engine will be put into
service.
2.3 INSTALLATION INSTRUCTIONS
The correct installation of the engine is very
important to achieving optimum performance and
extended engine life.
In this respect, the engine has certain installation
requirements, which are critical to how it performs.
These requirements are generally associated with the
cooling, exhaust, induction air, and fuel systems.
This section of the manual should be read in
conjunction with the relevant Installation and
Operation Data Sheets. If there is any doubt about an
installation, contact should be made with Clarke
Customer Support giving exact details of the
problem.
All installations should be clean, free of any debris
and dry. Care should be taken to ensure that there is
easy access to the engine for maintenance and repair.
The safety of personnel who may be in the area of the
engine when it is running is of paramount importance
when designing the installation layout.
1) Secure pump set to foundation and complete
installation in accordance with pump
manufacturer’s instructions. Perform engine-
to-pump coupling alignment.
2) Engine with Air Cooling: Connect air duct
flange on the engine to the air outlet ducting
in the pump room. Discharge ducting should
be installed in accordance with applicable
codes. A flexible duct section should be
provided to isolate engine from building.
3) Connect raw water plumbing from fire pump
discharge to the cooling loop which comes to
the oil cooler on the engine.
4) Engine is shipped with oil installed. For
make-up oil specification refer to section 3.3
Lubrication System.
5) Connect fuel supply and return line to fuel
supply tank plumbing. Reference the Fuel
System section of the Installation and
Operation Data in the Technical Catalog, for
piping size, maximum allowable fuel pump
suction, and maximum allowable fuel head
requirements. Fill supply tank with #2 diesel
fuel (ASTM D-975) or BS 2869 Class A2
“Red” diesel fuel, bleed supply system of air
and check for leaks. Fuel supply level must
meet applicable code requirements. Do not
use a copper based or galvanized material for
any component of a diesel fuel system. The
fuel will chemically react with the zinc
resulting in clogged fuel filters and injector
systems.
6) Remove protective covering on air cleaner
element.
7) Connect space heater (if supplied) to AC
power source. The electrical supply

8
requirements are indicated on the AC
electrical wiring. Connect the supplied heater
connection wire directly to a customer
supplied electrical junction box. Supply
wiring should never be routed through the
engine gauge panel. Severe damage to
critical engine control components could
result.
8) Connect exhaust system to flexible
connection on the engine. The exhaust
system plumbing must be supported by the
building structure and not the engine. The
exhaust flexible connection is provided only
for the purpose of thermal expansion and
vibration isolation, not for misalignment or
directional change.
9) Make electrical DC connections between the
engine gauge panel terminal strip (if
supplied) and the controller per the controller
manufacturer’s instructions.
10) Fill batteries with electrolyte per battery
manufacturer’s instructions. Connect cables
between engine and batteries only after
electrolyte is installed. Refer to the wiring
diagram inside the engine gauge panel cover
(if supplied), or appropriate wiring diagram,
for correct positive and negative connections.
Connect negative cables directly to the
ground stud. Connect each positive cable to
the starter contactors.
11) Note: Clarke Operation and Maintenance
Instructions Manual and Clarke parts
illustration pages are furnished with the
engine.
12) IMPORTANT! In order to obtain prompt
Warranty Service, this engine must be
registered to the final installation name and
address. To register this engine, go to
www.clarkefire.com and select Warranty

2.4 COUPLING ALIGNMENT INSTRUCTIONS
Various types of couplings or drive shafts could be
used with these engines. Refer to coupling
manufacturer’s alignment procedure.
2.5 WEEKLY TEST
An experienced operator should be present during the
weekly test.
NOTE: This engine is designed to operate at rated
load conditions. For testing purposes the engine can
be run at lower load (lower flow) conditions.
Running times in any one period should not exceed
30 minutes maximum.
Before starting the engine make sure of the
following:
1) The operator has free access to stop the
engine in an emergency.
2) The plant room ventilation ducts are open
and the engine has good access for air.
3) All the guards are in position and, if not, for
whatever reason, any rotating parts will be
free and clear without restriction.
4) Battery covers are in place and there is
nothing on top of or touching the engine,
which is not part of the original supply
specification.
5) Air Cooling: The air supply for cooling and air
ducting to outside of the building have no
restrictions.
When engine is running make sure that the oil
coolant temperature, oil pressure and raw cooling
water flow are within the limits specified on the
relevant Installation & Operation Data Sheet.
If the coolant temperature is excessive, check the
cooling loop strainer and proper operation of water
solenoid valve.
2.6 STARTING/STOPPING THE ENGINE
2.6.1 Special Notes to Equipment Installer of an
LPCB Approved (LPS1239) Engine Model: Any

3.0 ENGINE SYSTEMS
3.1 FUEL SYSTEM
3.1.1 Bleeding the Fuel System
CAUTION: Escaping fluid under pressure can
penetrate the skin causing series injury. Relieve
pressure before disconnecting fuel or other lines.
Tighten all connections before applying pressure.
Keep hands and body away from pinholes and
nozzles, which eject fluids under high pressure.
Use a piece of cardboard or paper to search for
leaks. Do not use your hand.
If ANY fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor
familiar with this type injury or gangrene may
result. Doctors unfamiliar with this type of injury
may call the Deere & Company Medical
Department in Moline, Illinois, or other
knowledgeable medical source. Ref figure #10
Whenever the fuel system has been opened up for
service (lines disconnected or filters removed), it will
be necessary to bleed air from the system.
If engine will not start, it may be necessary to bleed
air from fuel system at fuel injection pump or
injection nozzles as explained next.
3.1.2 Changing the Fuel Filter
It may also be necessary to change filters out with the
recommendations in the event of:
1) The engine has had an overhaul.
2) The quality of the fuel is questionable.
3) The engine has been subjected to temporary
adverse conditions outwith it normal
operating parameters.
4) The fuel tank condensation trap has not been
drained in line with manufacturer’s
recommendations.
3.1.3 Fuel Tanks
Keep the fuel tank filled to reduce condensation to a
minimum. Open drain at the bottom of the fuel tank
once a week to drain off any possible water and/or
sediment. Fill tank after each test run.
3.2 AIR/EXHAUST SYSTEM
3.2.1 Ambient Conditions
Clarke engines are tested in accordance with SAE
J1349 (Clarke USA) or ISO 3046 (Clarke UK). In
this capacity they may be derated to meet certain site
conditions, failure to do so can seriously impede the
performance of the engine and could lead to
premature failure.
3.2.2 Ventilation
The engine must be provided with adequate
ventilation to satisfy the requirements of the
combustion system, radiator cooling systems where
fitted, and allow adequate dissipation of radiated heat
and crankcase emissions. For all this data refer to
Installation & Operation Data. This data can be used
for proper sizing of inlet and outlet louvers.
3.2.3 Standard Air Cleaner
Should a situation occur where the air cleaner
becomes plugged with dirt (starving the engine of
air), loss of power and heavy black smoke will result;
the air cleaner should be replaced immediately.
CAUTION: Do not attempt to remove the air
cleaner while an engine is running nor run the engine
while the air cleaner is off. Exposed components
could cause severe injury to personnel and major
internal engine damage could occur should any
foreign matter be drawn into the engine.
3.2.4 Crankcase Ventilation
3.2.4.1 Open Crankcase Ventilation
Vapors which may form within the engine are
removed from the crankcase and gear train
compartment by a continuous, pressurized ventilation
system.
A slight pressure is maintained within the engine
crankcase compartment. Vapors expelled through a
vent pipe.
3.2.5 Exhaust System
Figure #10

12
Excessive back pressures to the engine exhaust can
considerably reduce both engine performance and
life. It is therefore important that exhaust systems
should be the proper diameter and be as short as
possible within the minimum amount of bends. Refer
to Installation & Operating Data for exhaust data.
The installation of the exhaust system should consist
of the following:
Personnel protection from hot surfaces.
Adequate supports to prevent strain on the
engine exhaust outlet and minimize
vibration.
Protection against entry of water and other
foreign matter.
While the engine is running inspect exhaust pipe
outlet outside of the pump room itself for
environmental hazards such as excessive smoke
conditions. The following could be used as a guide
for general engine operating conditions.
1) Blue Smoke – Possible engine oil
consumption.
2) White Smoke – Possibility of water in
cylinders, water in fuel or internal engine
problem.
3.3 LUBRICATION SYSTEM
3.3.1 Checking Sump Oil
Check the sump oil level using the dipstick on the
engine. This level must always be between the
dipstick marks Min. and Max. with the engine not
running.
3.3.2 Changing Engine Oil
1) Operate the engine until it is warm.
2) Stop the engine. Remove the sump drain
plug and drain the lubricating oil from the
sump.
3) Fill the sump to the ‘FULL” mark on the
dipstick with new and clean lubricating oil of
an approved grade. Fit the drain plug tighten
the plug to 34 Nm (25lbf-ft) / 3.5 kgf-m.
4) Return the unit back into service by returning
the AEC selector to “automatic” position and
the manual operating lever to manual stop
position.
5) Dispose used oil properly.
3.3.3 Changing Oil Filter
1. Turn engine off.
2. Put a tray under the filter to retain spilt
lubricating oil.
3. Remove the filter with a strap wrench or
similar tool. Then dispose of the filter
properly.
4. Clean the filter head.
5. Add clean engine lubricating oil to the new
filter. Allow the oil enough time to pass
through the filter element.
6. Lubricate the top of the filter seal with clean
engine lubricating oil.
7. Fit the new filter and tighten it by hand only.
Do not use a strap wrench.
8. Ensure that there is lubricating oil in the
sump.
9. Operate the engine and check for leakage
from the filter. When the engine has cooled,
check the oil level on the dipstick and put
more oil into the sump, if necessary.
10. Return the unit back into service by returning
the main pump controller selector to
“automatic” position and the manual
operating lever to AUTO-OFF position.
3.3.4 Oil Specification
Important: Do not add makeup oil until the oil
level is BELOW the add mark on the dipstick.

IMPORTANT: Set main pump controller to “OFF”
while servicing engine. Before turning the main
pump controller to the "OFF" position, check with
the maintenance and security supervisors to verify
that all the departments concerned will be alerted of
the temporary interruption of their fire protection
equipment for normal maintenance or testing. Also,
alert the local fire department in the event that the
main pump controller is connected by silent alarm to
headquarters. When servicing is complete, return
main pump controller selector to "Automatic"
position and the mode selector on the engine to
“Automatic” position. Advise the appropriate
personnel the engine has been returned to the
