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
