40 • Section 6 — Operation
The joystick or lever controls on the left hand control pod
provide for turntable rotation and boom extend/retract.
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.
CAUTION
Injury and property damage can result from abrupt
reversals in direction, starts, or stops. Operate the
controls smoothly.
On units equipped with the joystick control, pushing for-
ward on the joystick extends the boom and pulling back
on the joystick retracts the boom. Tilting the joystick to
the right rotates the turntable clockwise, and tilting the
joystick to the left rotates the turntable counterclockwise as
indicated on the joystick placard shown in Figure 6.4.
On units equipped with the two lever left hand control,
pushing forward on the right side lever extends the
boom and pulling back on the right side lever retracts
the boom. Pushing forward on the left side lever rotates
the turntable clockwise, and pulling back on the left-side
lever rotates the turntable counterclockwise as indicated
on the two-lever placard shown in Figure 6.4.
As the hand control is moved further from neutral, the
speed of the function is proportional to the distance the
hand control is shifted. The foot throttle or engine speed
switch may also be used to increase the speed of a func-
tion when operating the boom and winch functions.
Outrigger Up/Down Controls
When equipped with riding seat outrigger controls, the
outrigger/crane functions switch must be placed in the
Outrigger position to operate the outriggers. Only vertical
outrigger control is available from the riding seat.
Glide Swing
This control enables the glide swing if equipped.
Telescope Lockout
This control if equipped disables boom extend and retract
function when actuated.
Pole Guide
The pole guide if equipped may be opened or closed and
tilted forward or back with these controls.
Cabin Heater
When equipped with a cabin heater this control may be
used to adjust the cabin temperature.
Gauge
There is one gauge located on the control panel. This
gauge indicates the pressure in the hydraulic system.
The gauge for the hydraulic system can be used to give
the operator an idea of how hard the unit is working. To do
this, note the reading on the gauge when the load begins
to move. Compare this reading with the maximum system
pressure [3,300 psi (227.53 bar)]. Some troubleshooting
techniques, as described in the Maintenance Manual,
also use this gauge.
Right Hand Control Console
Two individual spring centered levers are located on the
right hand side of the control station.
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.
Each lever activates a pair of pressure reducing valves
using pilot pressure to activate the main control valves. The
handles may be operated individually or in combination.
CAUTION
Injury and property damage can result from abrupt
reversals in direction, starts, or stops. Operate the
controls smoothly.
Boom Lift Lever
The lever to the far right controls boom lift, except on
units equipped with dual winches, in which case boom
lift is controlled by the center lever. To operate the boom
lift function, move the handle from neutral. Pushing the
lever forward lowers the boom and pulling back on the
lever raises the boom. As the hand control is moved
further from neutral, the function speed is proportional to
