LIFT KICKOUT ADJUSTMENT PROCEDURE
1.
2.
3.
4.
5.
6.
Lift the bucket to the desired height.
Adjust magnet assembly (1) on lift arm (3) so
that the lower edge of the magnet is even with
the lower edge of switch assembly (2).
Adjust switch assembly (2) to get a clearance
between the switch and magnet assembly (1) of
6 to 10 mm (.24 to .39 in.).
Tighten the bolts that hold the magnet assembly
in place.
Start and run the engine. The lift kickout switch
action must move the lift control lever from
RAISE to HOLD position before the lift arm
assembly gets to the top of its travel.
If the kickout was too soon, move magnet assem-
bly (1) away from switch assembly (2). If the
kickout was not soon enough (cylinder rods hit
the heads inside the lift cylinders), move magnet
assembly (1) toward switch assembly (2).

BUCKET POSITIONER ADJUSTMENT
PROCEDURE
1.
2.
With the engine running, move the tilt control
lever to put the bucket in the correct angle to dig
and then move the tilt control lever to the HOLD
position. Lower the bucket to the ground and
stop the engine.
Make sure that magnet assembly (2) has its
longer length perpendicular (in a vertical posi-
tion) to tube assembly (1). Tighten the set
screws in the magnet assembly.
3. Measure dimension (A) between magnet assem-
bly (2) and switch assembly (3). The correct
dimension is 6 to 10 mm (.24 to .39 in.).
4. To change dimension (A), loosen bolts (5) then
tighten screw (4) just enough and move tube
assembly (1) and the switch away from magnet
assembly (2). Switch assembly (3) must be verti-
cally centered with magnet assembly (2).

bly (under cover). 4. Screw. 5. Bolt (two). A. Dimension
6 to 10 mm (.24 to .39 in.).
5. Move tube assembly (1) until the front edge of
switch assembly (3) is even (flush) with the front
edge of magnet assembly (2).
6. Loosen screw (5) and tighten two bolts (6) to a
torque of 15 ± 4 N.m (11 ± 3 lb. ft.).
7. Start and run the engine. Put the lift arm assem-
bly parallel to the ground with the bucket in a
full dump position. Put the tilt control lever in
the TILT BACK (detent position). The action of
the bucket positioner moves the control lever
from TILT BACK to HOLD position when the
bucket is at the correct angle to dig.
8. If the bucket angle to dig was too flat, move tube
assembly (1) and the switch toward the bucket.
If the angle to dig was too much, move tube
assembly (1) and switch toward the tilt cylinder.
