WARNING:
 Avoid sudden steering while moving the machine
at high speeds, while moving on a steep slope, or
while raising the lift arms. Failure to do so may
cause the machine to turn over.
 Never attempt to stop the engine while steering
the machine. If the engine is stopped, the
steering wheel will lock and the parking brake
will be applied so that steering will be impossible.
Never stop the engine while moving the machine.
 Never steer while raising the lift arm high as it is
extremely dangerous and may cause the machine
to turn over.
IMPORTANT: When the steering wheel is fully turned,
the front and the rear chassis come in contact
with the stoppers so that the steering wheel does
not rotate further. If the steering wheel is forcibly
turned further, the engine may stall or steering
system problems may result.
Turn the steering wheel toward the direction you intend to
steer the machine during operation.
f
NOTE: This machine has an articulated frame design.
The front and rear chassis are coupled by connection pins
(center pins) so that the rear wheels follow the tracks of
the front wheels.
Turn the steering wheel slowly so as to follow the motion
of the machine.
