3.2 STARTING INSTRUCTIONS

the beginning of this section.
2. Ensure the hydraulic controls are in the
neutral position (
T90059
).
3. Place the engine throttle control in the
low idle position ( T90059 ).
4. Make sure bystanders are clear of area.
5. Preheat the engine glow plugs, turn the
ignition key counter clockwise, for 10
seconds (

).
6. Engage the engine starter by turning the
ignition key fully to the clockwise posi-
tion (

engine has started.
Do not engage the starter for more
than 15 seconds intervals. Repeat the
preheat procedure if the engine fails to
start. Allow the starter to cool to
ambient temperature after 3 consecutive
starting attempts. Failure to do
so may cause premature starter
and / or engine stop solenoid failure.
