6.2 Engine Oil & Coolant
Check the oil level daily and top up if necessary.
Check the oil level when the engine is stationary and
on a level surface.
Do not overfill. The oil level should be as marked on
the dipstick when it is pushed into the engine.
Replace the oil as recommended. When changing the
oil or topping
-
up, use oil of grade suitable for the
prevailing ambient temperatures (Check engine
manuals).
Check the coolant level daily and top up if necessary.
Check the radiator and hoses for signs of damage or
leaks.
Check the cap and seal for signs of damage..
Check the coolant level when the engine is stationary
and on a level surface.
Do not overfill. The coolant level should be as marked
on the expansion bottle.
Replace coolant every 12 months or as specified.
Drain the waste fluids into suitable waste containers,
and follow HSE recommendations regarding the
handling and disposal of contaminated oil products.
6.3 Fuel System
Check the semi
-
transparent pre
-
filter for signs of water
contamination and replace is necessary.
Change the main filter in accordance with the engine
manufacturer’s schedule and instructions.
6.4 Valve Clearances
Valve Clearances should be checked as specified by
the engine manufacturer. Refit the rocker cover with a
new gasket.
6.5 Battery
Check the level of the battery electrolyte every day
(where possible). This should cover the plates. The
battery is a maintenance free unit and should not
require the electrolyte being topped up.
Check that the positive and negative terminals are tight
and secure, and free from corrosion. Lightly coat them
with petroleum jelly or similar to protect from corrosion.
Check that the battery securing strap/clamp is tight and
the battery is held firmly.
6.6 Alternator
Ensure that the cooling air vents do not become
blocked by dirt, debris etc.
6.7 Earth Leakage Unit / RCD
The earth leakage unit has a self test button which
can be used to apply a fault and to check that the unit
trips out when the generator is running.
6.8 Control Module Safety Shut Down
This module will prevent the generator from starting or
shut it down if faults occur. Check the following:
-
Hours Run Counter
: Confirm counter is working with
the engine running.
Over cranking
: Remove the 12V DC supply to the
starter motor solenoid and attempt to start. After 3
attempts the Control Module should stop and show an
alarm.
Low Oil Pressure
: With the engine off, remove the
connection to the normally closed oil pressure switch
and attempt to start the engine. The Control Module
should see an open circuit representing oil pressure
when there should be none and prevent starting.
With the engine running short the oil pressure switch
to the generator chassis to simulate loss of oil pres-
sure and the module should shut down the engine
and show an alarm.
Low Fuel Level
: The sensor is connected to the low
oil alarm circuit. With the engine running allow the fuel
tank to run out of fuel and the engine should stop and
the Low Oil alarm should be seen. Refill with fuel and
the engine should start and run normally.
