755/760i Operating instructions
Starting the engine
Before starting the engine do the daily checks, see page 27. Adjust the seat and mirrors (if fitted) so that you have a good
working position and unrestricted field of vision from the driver’s seat. Check that all controls function correctly. See
to it that the operating area is safe. Read and follow operating and safety instructions.
Stopping the engine (Safe stopping procedure)
1. Lower the boom completely down. Place attachment firmly on the ground, engage parking brake, stop the attachment
(move auxiliary hydraulics control lever to neutral position, see page 23), set engine revs to idle.
Allow the engine to run at idle speed or without load for a couple of minutes to allow for the
turbocharger to cool down before switching off the engine. After heavy use this is particularly
important to ensure long service life for the turbocharger.
2. Stop the engine by turning the ignition key to the OFF position (to the left)
3. Release auxiliary hydraulics pressure (see page 15).
4. Prevent unauthorized use of the loader. Take off the ignition switch and turn the power off with the battery disconnect switch.
Stop the engine as soon as possible, if any of the following symptoms is observed. Find out the cause before restarting.
• The coolant temperature warning light, oil pressure warning light, or malfunction indication light turns on during operation.
• Engine rpm increases and decreases suddenly by itself, without touching the throttle lever
• A sudden and unusual noise is heard
• The colour of the exhaust fumes suddenly darkens or turns white.
1. Turn the battery disconnect switch to ON
2. Move the hand throttle lever to idle position
3. Make sure that auxiliary hydraulics is switched off (lever in neutral
position). Do not press on the drive pedals.
4. Turn the ignition key to the right, to ON position. All eight engine
related signal lamps will light up briefly for self-check. Check engine,
engine oil pressure, and charge indicator lights will remain lit.
5. Turn the ignition key further to the right, to glow position.
The ECU controls the grid heater, and in very cold ambient
temperatures the glow indicator lamp will light up. If lit, hold key in
this position until lamp has gone out.
6. Turn the ignition key further to the right, to start position and hold
until engine starts.

according to table
If auxiliary hydraulics is switched on during starting and there is a hydraulically operated attachment on
the machine, the attachment can move suddenly and cause a dangerous situation. Make sure that the
auxiliary hydraulics control lever is in neutral position during starting.
Do not actuate the starter for more than 15 seconds at a time. If the engine does not start, wait for one minute before
repeating attempt. If the engine does not start after a few attempts, or runs poorly, see troubleshooting on page 37 and
the engine owner’s manual.
After starting:
Allow the engine to warm up and engine oil to circluate in the
engine before loading the engine or increasing engine revs.
lmmediately increasing the engine speed upon start-up will
cause the turbocharger to run at high speed before proper
lubrication, which may shorten the life of the turbocharger.
Make sure that all the warning lights on the control panel are off
when the engine is running. If the engine does not start after a
few attempts, or runs poorly, see troubleshooting on page 37.
