ADJUSTING WORK EQUIPMENT POSTURE 3
WARNING
q Stop the machine on flat ground and put blocks in
front and behind the wheels.
q Set parking brake lever to the LOCK position.
q Secure the front and rear frames with the safety bar.
q Always attach the warning tag to the work equipment
control lever.
q Do not go under the work equipment when the arm is
raised. To support the work equipment securely, use a
strong support that can withstand the weight of the
work equipment and prevent the arm coming from
down.
The boom kickout makes it possible to set the bucket so that it
automatically stops at the desired lifting height (lift arm higher
than horizontal) and the bucket positioner makes it possible to
set the bucket so that it automatically stops at the desired dig-
ging angle. The setting can be adjusted to match the working
conditions.
ADJUSTING BOOM KICKOUT 3
1. Raise the bucket to the desired height, set the lift arm con-
trol lever at HOLD, then set the safety lever to the LOCK
position and stop the engine.
2. Loosen two bolts (1), and adjust plate (2) so that the bot-
tom edge is in line with the center of the sensing surface of
proximity switch (3). Then tighten the bolts to hold the
plate in position.
3. Loosen two nuts (4) to make a clearance of 3 to 5 mm
(0.118 to 0.197 in) between plate (2) and the sensing sur-
face of proximity switch (3). Then tighten the nuts to hold
in position.
Tightening torque: 14.7 to 19.6 N·m (1.5 to 2.0 kgf·m, 10.8
to 14.5 lbft)
4. After adjusting, start the engine and operate the lift arm control lever. Check that the lever is automatically
returned to HOLD when the bucket reaches the desired height.
