PRECAUTIONS FOR OPERATION

START ENGINE

USE WARNING TAGS

If there is a "DANGER! Do NOT operate!" warning tag dis-
played, it means that someone is performing inspection and
maintenance of the machine. If the warning tag is ignored and
the machine is operated, the person performing inspection or
maintenance may be caught in the rotating parts or moving
parts. It is dangerous and may cause serious personal injury or
death. Do not start the engine or touch the levers.

CHECKS AND ADJUSTMENT BEFORE STARTING ENGINE

Perform the following checks before starting the engine at the beginning of the day's work to ensure that there is
no problem with the operation of the machine. If these checks are not performed properly, problems may occur
with the operation of the machine, and there is a danger that may lead to serious personal injury or death.

Perform the walk-around check securely according to "METHOD FOR WALK-AROUND CHECK (3-150)".
Remove all dirt from the surface of the lens of the headlamps, working lamps, and combination lamps, and
check that they light up correctly.
