MAINTENANCE NOTES
157
4.2.1.3 FUEL
q
Always use fuel suitable for the engine. Other fuels with different specifications may damage the engine or redu-
ce its power.
q
Always refuel at the end of the work day.
q
When refuelling, make sure that there is no water on the fuel drum cover and take care not to draw the conden-
sate from the drum bottom.
q
If fuel runs out, or if the fuel filter has been replaced, it is necessary to bleed the pipes.
4.2.2 NOTES REGARDING THE HYDRAULIC SYSTEM
q
Be extremely careful when performing maintenance operations on the hydraulic system, since soon after work
the oil is very hot.
The circuit is pressurized not only during work, but also at the end of work.
q
The maintenance operations required for the hydraulic system are the following:
1 - daily check of the oil level in the tank;
2 - periodical change of the oil filter;
3 - periodical change of the oil.
q
Always bleed the circuit after changing the oil filter or the oil.
q
When a component is removed from the circuit, check the gaskets and O-rings and change them if they are da-
maged.
q
When a cylinder or a component of the hydraulic circuit is removed, after reassembly bleed the circuit by proce-
eding as follows:
1 - start the engine and let it idle;
2 - make all the cylinders perform 4-5 movements, stopping them at approx. 100 mm from the end of their stroke;
3 - slowly make all the cylinders reach the end of their stroke for 3-4 times.
4.2.3 NOTES REGARDING THE ELECTRICAL SYSTEM
q
If the cables are wet or their insulating material is damaged, the electrical system leaks and this may result in
malfunctions of the machine.
q
The maintenance operations required for the electrical system are the following:
1 - check of the alternator belt tension;
2 - check of the alternator belt for damage or breakages;
3 - check of the battery electrolyte level.
q
Do not remove or eliminate any electrical component installed on the machine and do not install any electrical
component with characteristics different from those specified and approved by Komatsu.
q
Be careful to keep the electrical system dry.
q
When working on seashores or river or lake banks, protect the jack plugs from corrosion.
q
Do not connect any optional device to the fuses, ignition switch, battery, relays, etc.; for the installation of any op-
tional equipment, contact your Komatsu Dealer.
q
If any electric welding operation has to be carried out, disconnect the battery and the alternator.
