when required
1. Lower the bucket to the ground as shown
on the figure above in a stable position.
2. Check that the bucket dose not move,
and then set the safety lock lever to the
locked position and stop the engine.
3. Move the O-ring (1) to bring the gap (A)
into view and measure the width of the
gap (A).
The gap (A) should be 0.5 mm (0.02 in.).
Swing the upperstructure slightly to the left
and lightly press the arm point to the left

in.)
Be careful that the gap is no less than 0.5
mm (0.02 in.) after adjustment.
Note:
Example (for a gap of 2 mm or 0.08 in.):
2 mm - 0.5 mm (standard value)= 1.5 mm
(0.06 in.)
In the above example, three shims (5) should
be removed.
6. Insert the adjustment shim(s) (5) removed
in step 5 above between the end plate (3)
and the flange (4), and then fasten it in
