Maintenance
The coolant is pressurised and at high
temperature with the engine switched on.
When the cap is removed, the liquid may
flow out violently and cause serious burns.
Make sure the engine is cold before
working on the cooling system.
Checking
1 Set the vehicle in the parking position.
2 Check the level in the expansion tank
placed above the radiator. The level is
correct when it is half-way on the
inspection window.
3 Open the tank, check the coolant additive
concentration ratio using the instrument
concerned (e.g. hydrometer,
refractometer)
4 If necessary, top up with a suitable
mixture depending on the use.
5 Refit the cap and make sure it is tightened
properly. Run the engine to bring it to the
required temperature. Switch off the
engine and check for leaks in the circuit.
A-4 Telescopic boom sliding
blocks - check
1 Extend the telescopic boom completely.
2 Check to make sure the boom movement
is smooth. Ensure that there are no
abnormal vibrations, unusual noises, and
no part of the boom gets heated due to
friction during the movement.
3 Remove the dust guard gaskets at the
head of the extensions and check to
ensure there is a sufficient layer of grease
on the sliding surfaces and on the sliding
blocks.
