Description Of Machine and Controls
Boom Telescope Switch
- Pushing upward and forward on the rocker switch will extend the boom
sections. Pulling downward on the switch will retract the boom sections.
OPERATION WITH ONLY ONE WINCH
- Push forward on center rocker switch to extend the boom sections. The speed of the boom
extend is proportional to the throttle setting and movement of the switch.
- Pull back on center rocker switch to retract the boom sections. The speed of the boom
retract is proportional to the throttle setting and movement of the switch.
- Move to the right to turn the turrent clockwise. The swing speed is proportional to the throttle
setting and movement of the joystick.
- Move to the left to turn the turrent counterclockwise. The swing speed is proportional to the
throttle setting and movement of the joystick.
When the hand control is in the middle position (e.g. boom extension and turrent clockwise
rotation) the two functions are activated at the same time.
OPERATIONS WITH AUXILIARY WINCH (optional)
- Push “AUX WINCH ON/OFF” to “DISABLE” the Auxilary winch, LED green light will come
“ON”, winch function will be disabled. The Auxilary winch function when it is not being utilized
prevents damage to the cable when it is on the winch, but not rigged over the boom head.
(e.g. cable tied off to winch drum, etch)
- Depress switch to change Auxilary winch speed to “HI”, LED red light will come “ON” and
Auxilary winch wire rope take in and pay out speed will be in “HIGH” speed mode.
- Move to the right to turn the turrent clockwise
- Move to the left to turn the turrent counterclockwise
- Pull back to lift the load with the auxiliary winch
- Push forward to lower the load with the auxiliary winch
Release the main or auxiliary winch rope when extending the boom to prevent the
hoisting block head from tripping the limit stop device. Failure of this device can result
in serious damage to the boom head or telescopic extension and the rope. The rope
could break causing the load to drop, with resulting serious damage or fatal accidents.
Internal to the handle is a thumper indicator that is felt by the operators hand to assist in the speed
the winch drum is traveling when the Auxiliary winch joystick is moved forward or backward.
Manual superstructure rotation brake release switch
To release the friction swing brake manually and allow self-alignment of the boom end vertically
over the center line of the load being lifted, flip the
Swing Brake Switch
on the right armrest.
Do not change the winch speed if the winch joystick is not in the neutral position and
the drum is turning.
