WARNING: When the steering wheel is turned, the
clearance between the front and rear frames becomes
narrower, possibly creating a hazardous situation such
as entanglement of limbs. Keep any personnel away
from the frame articulation point during inspection.
Check that play (1) in steering wheel stroke is correct and
that steering column tilt telescopic lever (2) and pedal (3) are
securely held.
In addition, check that the steering wheel column normally
comes in contact with the stopper when the steering wheel is
fully turned and that the steering cylinder operates 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 knob in both clockwise
and counterclockwise direction. Measure the moving
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 play amount of the steering wheel is
