STARTING AND SWITCHING OFF THE ENGINE
5-14
WARMING UP THE ENGINE
☞
• You must not accelerate the engine abruptly before the
warm-up phase is finished.
• Do not let the engine run idle for longer than 20 minutes at
its lower or top speed. If it is necessary to let the engine
run idle for a longer time, you must load the engine briefly
from time to time or let it run idle at medium speed.
Do not immediately begin with work after starting the engine.
Prior to operation, perform the following preparations and
checks:
1. Press down slightly the accelerator pedal and let the engine
run without load at medium speed for approx. 5 minutes.
2. Proceed as follows in order to heat up the hydraulic oil at low
ambient temperatures:
Allow the engine to run consistently during the warm-up
phase. For warming the hydraulic oil, reset the multi-function
lever for the work hydraulic system in short intervals from
position ‘0’ (holding) into position ‘E’ (tip-in position). Then
resetittoits‘0’ position. Make sure not to exceed the maxi-
mum time (10 seconds) permitted for the multi-function lever
in the tip-in position.
3. While the engine is warming up, observe all measuring in-
struments and warning lights and eliminate immediately any
fault.
4. Let the engine run with lightweight load further until the en-
gine coolant temperature indicator (1) lights up in the green
range.
5. Ensure that the exhaust gas colour is normal and that the
exhaust pipe produces neither abnormal noises nor vibra-
tions. Eliminate possible defects.
