the distance the hand control is shifted. The foot throttle
or engine speed switch may also be used to increase
function speed when operating the boom function. When
released, the lever should return to neutral and the boom
motion should stop.
WARNING
Death or serious injury can result from two-blocking
the unit. The winch can break the load line if two-
blocked. Two-blocking may cause the load line to
fail and load/hook block to fall. Do not allow hook
block to contact boom tip by hoisting up, extending
or lowering boom.
Do not operate the winch function with the anti-two-block
switch disabled or the weight chain shortened. The weight
must be 30″ (76.20 cm) from the boom tip sheave.
Winch Control Lever
The lever on the near right controls the winch line.
To operate the winch function, move the handle from
neutral. Pushing the lever forward lowers the winch line
hook and pulling back on the lever raises the hook. As
the control is moved further from neutral, the function
speed is proportional to the distance the hand control is
shifted. The foot throttle or engine speed switch may also
be used to increase function speed when operating the
boom function. When released, the lever should return
to neutral and the winch line should stop.
On units equipped with dual winches, the right hand
control will have three levers instead of two. The lever
on the far right controls the auxiliary winch.
Winch Speed Selector Switch
The winch speed selector is located directly in front of
the right hand controls. This switch can be positioned to
select either low speed or high speed for the hydraulic
winch motor.
Drum Rotation Indicator
This crane is equipped with a drum rotation indicator,
which is located in the top of the winch control lever. It
provides a pulsating movement which can be felt by the
operator’s thumb, to indicate if the winch is turning and
how fast.
Radio Remote Switch
The radio remote switch transfers control of unit functions
between the seat control console and the radio remote
controls. By placing the switch in the On position, only
the radio remote can control unit operation. Placing the
switch in the Off position disables the radio remote and
returns control to the seat control console.
Signal Horn
The signal horn switch is located directly in front of the
right hand controls. When pressed, this momentary switch
sounds an audible signal.
Emergency Stop
The emergency hydraulic stop control stops the opera-
tion of all functions. Press the control down to engage
the emergency stop. Pull the control out to disengage
the emergency stop.
CAUTION
Injury and property damage can result from vehicle
movement if the transmission is not in neutral or
park when the engine is started. Make sure the
transmission is in neutral or park before remotely
starting the engine.
Engine Start/Stop
The engine start/stop switch (refer to Figure 6.4) may be
used to start and stop the vehicle engine from the control
panel. To start the engine, push the switch until the engine
is running and then release. If the engine does not start,
push the switch and release. Then repeat the procedure.
To turn off the engine, push the switch and release. The
switch is operational only when the cab ignition switch
is on and the emergency stop is not engaged.
Crane/Outrigger Functions Selector
Place the selector in the Crane Functions position to
operate the crane. Place the selector in the Outrigger
Functions position to operate the vertical outrigger con-
trols from the riding seat.
Winch Lockout
This control if equipped disables the winch function when
actuated.
Cab Tilt
This control if equipped tilts the operator’s cabin fore and
aft up to a maximum tilt angle of 20 degrees.
Throttle Hold
This control if equipped is a momentary switch which
holds a throttle setting similar to a cruise control. Using
the foot throttle, set the desired engine throttle setting,
and press and release the throttle hold switch. The foot
throttle may now be released and the engine rpm will
remain at the preset setting. To release the throttle hold
setting, press the throttle hold switch and release. The
engine will return to its idle setting.
