BOOM LOWER KICK-OUT (OPTION)
Placing bucket lever in "L" position will lock
control lever in lower boom position. Boom will
move downward until trip plate (2, Figure 44)
makes contact with bucket lower limit switch (1).
When limit switch is tripped, boom will stop
lowering and bucket lever will automatically be
returned to "NEUTRAL" position. Trip plate can
be adjusted to control maximum height that
boom can be lowered.
ADJUSTMENT OF BUCKET POSITION SWITCH
When bucket lever is held in crowd detent
position, after bucket has been dumped, bucket
will pivot toward crowd position. Once full crowd
position has been reached, bucket lever will
automatically return to "NEUTRAL" position. If
bucket is lowered after lever returns to
"NEUTRAL," bucket will automatically position
itself to be in a preselected digging position
(usually flat). To adjust bucket to desired
preselected digging position, perform the
following steps.
1. Operate controls to place bucket on
ground and in desired digging position
(usually flat). Return bucket lever to its
"NEUTRAL" position.
2. Shut down engine.
3. Loosen bolts (4, Figure 45) on bracket (3).
4. Position bracket (3, Figure 45) so that end of arm (1) is aligned with center of magnetic switch (2).
5. Tighten bolts (4, Figure 45).
6. Start engine. Raise boom, dump bucket, then move bucket lever into crowd detent position. Now
lower boom and check to see that bucket has stopped at required position. A small readjustment of
bracket (3, Figure 45) may be necessary.
IMPORTANT
Trip plate must always be set to contact
limit switch before boom cylinders reach
maximum extension. Maximum extension
causes pump to force fluid over relief
valve.
