Operation & Maintenance Manual

FUEL FILTER WATER SEPARATOR

The fuel filter water separator contains a filter element which should be replaced at regular
intervals (see the SERVICE/MAINTENANCE CHART).

CHARGE AIR COOLER PIPEWORK

Inspect all hoses and clamps on the charge cooler pipe work.
Engine damage will occur if the charge cooling system leaks.

HOSES

All components of the engine cooling air intake system should be checked periodically to keep
the engine at peak efficiency.
At the recommended intervals, (see the MAINTENANCE CHART), inspect all of the intake
lines to the air filter, and all flexible hoses used for air lines, oil lines and fuel lines.
Periodically inspect all pipework for cracks, leaks, etc. and replace immediately if damaged.

ELECTRICAL SYSTEM

Disconnect the battery cables before performing any maintenance or
service.
Check the security of electrical terminals on the switches and relays i.e. nuts or screws loose,
which may cause local hot spot oxidation.
Inspect the components and wiring for signs of overheating i.e. discolouration, charring of
cables, deformation of parts, acrid smells and blistered paint.

BATTERY

Keep the battery terminals and cable clamps clean and lightly coated with petroleum jelly to
prevent corrosion.
The battery restraint should be kept tight enough to prevent the battery from moving.

PRESSURE SYSTEM

Regularly, it is necessary to inspect the external surfaces of the system (from the airend
through to the discharge valve(s)) including hoses, tubes, tube fittings and the separator tank,
for visible signs of impact damage, excessive corrosion, abrasion, tightness and chafing. Any
suspect parts should be replaced before the machine is put back into service.
