OPERATING THE ENGINE
3-11
1
Warm Up
IMPORTANT: At starting the engine, the engine RPM
(min
-1
) is kept at low idle for maximum 35 seconds to
warm up the coolant, transmission oil or hydraulic oil.
After this period, the engine RPM will increase by
applying the accelerator pedal (3).
WARNING: Do not operate the machine while the
engine RPM is being kept at low idle, otherwise, the
machine or the front attachment could unexpectedly
move that may result in serious injury.
CAUTION: Operating the machine without warm
up causes damage to the engine and hydraulic
components. Be sure to perform warm up not only
to protect the hydraulic components from being
damaged but also to ensure safe operation.
If the machine is operated with the hydraulic oil temperature
below 20 °C (68 °F), damage to the hydraulic components
may result. After starting the engine, perform warm up as
described below before operating the machine until the
hydraulic temperature is above 20 °C (68 °F).
1. While releasing accelerator pedal (3), run the engine at
low idle speed for about 3~5 minutes with no load.
2. Increase the engine revolutions to 1200 min
-1
(RPM's).
Raise the bucket above the ground and hold bucket
control lever (1) in the tilt position for 10 seconds. (Do
not operate control levers other than the bucket control
lever at this time.)
