OPERATION
Machine Operation
Warming Up the Hydraulics
WARNING
Operating the working equipment without
warming up the hydraulics is dangerous,
because response will be slow and the
equipment may move in unexpected
ways. Be sure to sufficiently warm up the
hydraulics.
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, heat 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 bar to the released position
and lift the bucket from the ground.
3. Extend and retract each of the cylinders
several times with no load.
4. Travel slowly forward and backward
several times.
Warming Up in Cold Weather
1. Perform the normal warm-up procedure.
2. Set the bucket cylinder at the stroke end
and keep it there.
Do not do this for more than 30 seconds.
3. Repeat step 2 until the bucket operating
speed is normal.
