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. Be sure to sufficiently warm up the
machine.
IMPORTANT: Do not operate the
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, warm up the hydraulic oil
to at least 20°C (68°F).
Normal Warm-up
1. Run the engine at medium speed for
about 5 minutes with no load.
2. Set the safety lock lever to the released
position.
3. Extend and retract the dump cylinders
several times with no load.
4. Slowly swing the dump body several
times.
5. Slowly travel forward and backward
several times.
Warming Up in Cold Weather
1. Perform the normal warm-up procedure.
2. Set the dump cylinders at the stroke end
and keep them there.
Do not do this for more than 30 seconds.
3. Repeat step 2 until the dump body
operating speed is normal.
