USE OF THE MACHINE
3.6.3 WARMING THE ENGINE
3.6.4 HEATING THE HYDRAULIC OIL
3.6.5 HOW TO MOVE THE MACHINE
1 - After starting the engine, let it warm up before starting work.
2 - The ideal warming up of the engine is achieved with the engine running at idling speed, which is obtained with
the hand accelerator.
IMPORTANT
☞
•
Do not accelerate completely or abruptly until the coolant temperature has reached at least 60°C.
3 - To reduce the time necessary to warm up the engine, accelerate now and then.
4 - During the warming up of the engine, check the colour of the exhaust gases and verify if abnormal noises or
vibrations can be noticed; any anomaly must be verified and its cause must be eliminated.
When warming up the engine, especially in the cold season, it is advisable to heat also the hydraulic system oil.
For this reason, when the coolant temperature has reached approximately 60°C, proceed as follows:
1 - Release the safety device of the controls (See “3.1 SAFETY LOCKS”).
2 - Slowly extend and retract the arm and the bucket completely for several times.
3 - Lower the bucket to the ground and lock the safety device again.
DANGER
•
Before moving the machine, make sure that you know the control functions and all the relevant safety
regulations perfectly.
•
Make sure that the upper structure is directed towards the blade and lock it in this position by means of
the rotation lock.
•
The operator must be sitting in the driving position with fastened safety belt.
•
Before moving the machine, make sure that there is no one within the operating radius of the machine
and that there are no obstacles in the surrounding area.
•
Be extremely careful when engaging the reverse and make sure that there are no persons, working
means or obstacles in the way.
•
Avoid manoeuvres or changes of direction when travelling at full speed, since the manoeuvres carried
out in these conditions cause abrupt movements.
•
Do not use the speed increase function when changing direction or carrying out a counter-rotation.
