Warm up the engine (hydraulic oil)
It's really dangerous to operate the working
device without warm-up (Hydraulic oil), as
the working device can't respond quickly to
the controls or will motion probably in
unexpected manner and the safety devices
can't work normally probably. Therefore,
ensure to warm up the machine sufficiently.

temperature is <20℃, do not operate any
joystick quickly. During the operations, the
appropriate hydraulic oil temperature is
50~80℃. If it's necessary to operate under
low temperature, warm up the hydraulic oil
to at least 20℃.
Normal Warm-up
1. Pull the accelerator joystick to neutral
position. Then, run the engine at medium

speed under no-load condition for
approximately 5min.
2. Completely lower down the safety lock
handle to unlock and lift the bucket from
the ground.
3. Slowly telescope all cylinders for several
times under no-load condition.
