Machine Operation
Warming Up the Machine
(Hydraulic Oil)
WARNING
� Operating the working equipment
without warming up the machine
(hydraulic oil) is dangerous, as response
will be slow and the equipment may
move in unexpected ways and safety
devices may not operate properly.
Be sure to sufficiently warm up the
machine.
�
When traveling, do not step on the
travel pedal for the opposite direction.
Doing so is dangerous as it causes the
machine to stop suddenly.
IMPORTANT: D o n o t o p e r a t e t h e
levers suddenly when the hydraulic oil
temperature is below 20°C (68°F). The
proper hydraulic oil temperature during
operation is 50 to 80°C (122 to 176°F), but
if operations must be performed at lower
temperatures, heat up the hydraulic oil to
at least 20°C (68°F).
Normal Warm-up
1. Run the engine at medium speed (FC
mode) for about 5 minutes with no load.
2. Set the safety lock lever to the released
position and lift the bucket from the
ground.
3. Disengage the boom swing pedal and
blade lever locks.
4. Extend and retract each of the cylinders
several times with no load.
