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.
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 (FC
mode) for about 5 minutes with no load.
2. Fully lower the safety lock lever to
disengage the lock and lift the bucket from
the ground.
3. Extend and retract each of the cylinders
several times with no load.
4. Slew slowly left and right several times.
