Operation 3-15
To raise boom to maximum height, past preset
height, hold pilot control valve lever (joystick) 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).
BOOM LOWER KICKOUT (OPTION)
Placing bucket lever in “L” position will lock
control lever in lower boom position. Boom will
move downward until trip plate (1, Figure 32)
makes contact with bucket lower limit switch (2).
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.
IMPORTANT
Trip plate (1, Figure 30) 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.
