WARNING: Pinch point. When the steering wheel
is turned, the clearance between the front and rear
chassis closes, creating a hazardous situation. Keep
personnel away from the chassis articulation point
during inspection.
Check that play (1) in steering wheel movement is correct
and that steering column tilt telescopic lever (2) and pedal
(3) are held securely. In addition, check that the chassis
steering stoppers come in contact with the opposing
chassis surface stopper when the steering wheel is fully
turned and that the steering cylinders operate normally.
1. Start the engine. Turn the parking brake switch ON.
2. Slightly lift the bucket above the ground. Place the
control lever lock in the lock ( ) position.
3. While running the engine at slow speed,
slightly rotate the steering wheel clockwise and
counterclockwise. Measure the beginning movement
distance along the steering wheel circumference
until both right and left steering cylinders start
moving (check the movement of the bucket and/or
tires).
Play amount (1): 5 to 15 mm (0.2 to 0.6 in)

NOTE: If too much steering wheel play is found or if the
steering wheel does not move smoothly, consult your
nearest authorized dealer for checking.
