BOOM RAISE KICK-OUT
Placing bucket lever in "Boom Raise Detent" position will
lock bucket lever in raise boom position. Boom will raise
until trip plate (1, Figure 43) 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 43) 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.
