ADJUSTING THE BUCKET POSITIONER
1. Lower the bucket to the ground and set the bucket to the de-
sired digging angle. Set the bucket control lever to HOLD,
stop the engine and adjust as follows.
2. Loosen two bolts (1) and adjust mounting bracket (4) of the
proximity switch so that the rear tip of angle (2) is in line with
the center of the sensing surface of proximity switch (3).
Then tighten the bolts to hold the bracket in position.
3. Loosen two nuts (5) and adjust to make a clearance of 3 to 5
mm (0.12 to 0.20 in) between bar (2) and the sensing sur-
face of proximity switch (3). Then re-tighten the nuts.
Tightening torque: 15 - 20 Nm
4. After the adjustment, start the engine and raise the lift arm.
Operate the bucket control lever to the DUMP position, then
operate it to the TILT position and check that the bucket con-
trol lever is automatically returned to HOLD when the bucket
reaches the desired angle.
