BOOM RAISE KICKOUT
Placing bucket lever in "Boom Raise Detent"
position will lock bucket lever in raise boom
position. Boom will raise until trip plate (1,
Figure 37) makes contact with bucket height
limit switch (2). When limit switch is tripped,
boom will stop raising and bucket lever will
automatically be returned to "NEUTRAL"
position. Trip plate can be adjusted to control
maximum height that boom can be raised.
To raise boom to maximum height, past preset
height, hold boom and bucket lever in "Raise" or
"Hold Raise" position until boom has reached
maximum height. Then remove your hand from
lever. Lever will automatically return to
"NEUTRAL" position. This prevents hydraulic
pump from working against relief valve
(maximum pressure).
BUCKET ANGLE
INDICATOR
Upper right side of bucket includes a bracket
that indicates angle of bottom of bucket. Top of
bracket is parallel with bottom of bucket. If
bottom of bucket is not visible, top of bracket will
be visible.
IMPORTANT
Trip plate (1, Figure 37) must always be set
to contact limit switch (2) before boom
cylinders reach maximum extension.
Maximum extension causes pump to force
fluid over relief valve.
