OPERATION
Machine Operation
3.Extend and retract each of the cylinders
several times with no load.
4.Slew slowly left and right several times.
5.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.
Warming Up the Machine
(Hydraulic Oil)
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, heat up the hydraulic oil
to at least 20
°C (68°F).
Normal Warm-up
1.Pull the throttle lever to the middle position,
then run the engine at medium speed for
about 5 minutes with no load.
: Release : Lock on
2.Set the safety lock lever to the released
position and lift the bucket from the ground.
