• A .... side raises the height.
B ..... side lowers the height.
If the correct height J cannot be obtained by
adjusting the switch box position, adjust the
cam plate (2).
• Slow down the engine’s rotational speed and
confirm that the height J is within the specified
range. Confirm the height J again at the engine’s
rated rotational speed.
Never try to adjust the boom raise stop position
using the switch setting adjustment. Otherwise,
the adjusted position may deviate and cause
interference between the boom and the cab.
Adjusting of the boom left offset stop position
1. Remove the installation bolts and the cover.
2. Adjust the offset switches R and L.
• The offset switches R and L should be adjusted
at the position where the cam roller (3) is on the
angle (1) and the switch stroke is shortened by
4 mm from the free position and set.
3. Adjust the angle (1) and confirm that the clear-
ance H between the boom and the cab in the left
offset state is within the specified range.
For the inspection of the clearance H, see the
section “Inspection when there is no interference
between the bucket and the cab.”
• The clearance H should be adjusted by shifting
the angle (1) upward or downward.
Moving the angle (1) upward narrows the
clearance H.
Moving the angle (1) downward widens the
clearance H.
• Slow down the engine’s rotational speed and
confirm the clearance H is within the specified
range.
Confirm the clearance H again at the engine’s
rated rotational speed.
• After adjustment, if the clearance H is still less
than 90 to 100 mm, place a shim (4) such as a
washer between the angle (1) and the link arm
(2).
