OPERATION
WARMING UP THE MACHINE
(HYDRAULIC OIL)
Operating the working equipment without
warming up the machine (hydraulic oil) is
dangerous, as the working equipment
cannot response to controls quickly or
may move in unexpected ways, and the
safety devices may not operate properly.
Be sure to sufficiently warm up the
machine.
IMPOR
TANT: Do not operate the levers
too quickly when the hydraulic oil
temperatur
e is below 20°C (68°F). The
proper hydraulic oil temperature during
operation is 50 to 80°C (122 to 176°F). If
operations must be performed at lower
temperatures, heat up the hydraulic oil to
at least 20°C (68°F).
Normal warm-up
OPERATING THE MACHINE
1. Pull the throttle lever to the middle
position, then run the engine at medium
speed 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
slowly several times with no load.
4. Slew slowly to the left and the right several
times.
