•
Wipe the filter fitting face clean.
•
Apply a light coat of engine oil to the O-ring
and supply fuel to the new filters.
•
Turn the new filter until the filter O-ring is
fitted against the sealing face.
•
And the turn the filter cartridge about ¾ ~ 1
turn more with hands or filter wrench.
CAUTION: DO NOT LEAVE SELECTOR
LEVER IN ANY INTERMEDIATE POSITION
BECAUSE THIS WOULD INTERFERE WITH
THE FUEL SUPPLY.

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.
Note:
Per NFPA 25 standards, the fuel tank level
must never be less than 67% of its capacity.

3.1.5 Fuel Injection Pump Components
For Droop Spring and Run-Stop Solenoid (external to
Injection Pump) part numbers consult factory.
3.1.6 Priming Pump Strainer Cleaning
Clean the priming pump strainer on an annual basis.
The plastic strainer is incorporated in the priming
pump inlet side “banjo” bolt. Clean any debris from
the strainer with compressed air and rinse it with fuel.

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 (see Page 5). This data can
be used for proper sizing of inlet and outlet louvers.
3.2.3 Standard Air Cleaner
The standard air cleaner is a reusable type. 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; if equipped
air filter restriction indicator (ref. Fig. #17A); the air
cleaner should be serviced immediately. See
Figure
#39
for air cleaner part numbers by Clarke Engine
Model.
