3.3.3.2 WARMING-UP OPERATIONS
IMPORTANT
q
Do not carry out any operation and do not shift the levers suddenly when the hydraulic oil temperature
is too low. Always carry out the warming up operations. This will lengthen the life of the machine.
q
Do not accelerate abruptly before completing the warming-up operations. Do not let the engine run at
low idling or high idling speed for more than 20 minutes without interruption. If it is necessary to let the
engine idle, accelerate every now and then or increase the speed up to an intermediate value.
After starting the engine, let it warm up before starting work. Carry
out the operations and checks indicated below.
1. Shift the accelerator lever (1) from the idling (A) to the
intermediate speed position (B), and let the engine idle at
medium speed for at least 5 minutes.
NOTE
q
When the ambient temperature is below 0°C, let the engine run
at low idling speed during the warming-up operations.
q
Do not accelerate completely or abruptly until the coolant
temperature has reached at least 60°C.
2. Move the safety lever (2) to working position (F) and lift the
bucket from the ground.
