7 - MAINTENANCE
5. Start the engine. Position the bucket flat on the ground.
Shut the machine off. Loosen the bolts holding the
target bar to the target mounting bracket. Slide the
target bar towards the proximity switch until the face
of the proximity switch is completely covered. Align the
target bar parallel to the tilt cylinder, and tighten the
bolts.
6. Turn the ignition switch to the on position (not acces-
sory position). Do not start the engine. Position the
bucket control lever to the full roll back position. The
electromagnetic detent should hold the control lever in
this position.
7. Loosen the bolts holding the target bar to the target
mounting bracket. Slowly slide the target bar away
from the proximity switch. When the proximity switch
face is nearly uncovered, the switch will be activated,
and the control lever will return to the center position.
Tighten the bolts maintaining this location of the target
bar. Verify that the
3.5 - 5 mm ( 0.1 - 0.2 in ) gap is main-
tained between the target bar and the proximity switch.
8. Make sure the proximity switch and all the mounting
bolts are tight. Start the engine. Set the detent switch to
the on position, and set the return to travel/float detent
switch to the return to travel position. Raise the lift
arms to approximately the horizontal position. Position
the bucket to the fully dumped position. Put the loader
control lever in the roll back position, and verify that the
electromagnet holds it in that position until the end of
the target bar passes in front of the proximity switch.
Lower the lift arms to the ground, and verify the bucket
is flat on the ground.
