Fuel System
The fuel tank should be filled daily or every eight hours. To minimize condensation in the fuel
tank(s), it is advisable to top up after the machine is shut down or at the end of each working
day. At six month intervals drain any sediment or condensate that may have accumulated in
the tank(s).
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 clips 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 SERVICE/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 pipe work for cracks, leaks, etc. and replace immediately if damaged.
Electrical System
WARNING
!
Always disconnect the battery cables before performing any
maintenance or service.
Inspect the safety shutdown system switches and the instrument panel relay contacts for
evidence of arcing and pitting. Clean where necessary.
Check the mechanical action of the components.
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. discoloration, charring of
cables, deformation of parts, acrid smells and blistered paint.
