2-2
Published 5-27-2018 Control # 039-06
Power Shift Control – If the vehicle is equipped with
automatic transmission, the power take-off must be engaged
with the engine at idle. Refer to transmission manufacturer’s
instructions for special procedures.
Park Brake
The truck brake must be firmly set before leaving cab to
begin operation. If the ground surface is icy or slick or is
sloped, you may be required to help immobilize the truck with
wheel chocks.
CRANE CONTROLS
The unit is equipped with control stations on each side of the
main frame. Placards on the control knobs or next to the
lever indicate the direction to actuate the controls for the
various unit functions. Each station is complete and provides
complete control of boom rotation, boom elevation, boom
extension, hoist, outriggers, engine foot throttle, the engine
emergency stop switch and a horn switch. All control handles
except the outrigger controls are positioned in the same
order at both control stations. The hydraulic system pressure
gauge is located at only one operator’s station.
Control Functions
Turn – Operate the lever to RIGHT to rotate the boom in a
clockwise direction. Operate the lever to LEFT to rotate the
boom in a counterclockwise direction as viewed from the top
of the crane.
A mechanical rotation stop pulls the turn control lever back to
the center position when engaged. The boom rotation is
stopped over the front of the chassis. On rear mounted
cranes, rotate the boom over the passenger side of the
chassis when stowing and unstowing to prevent immediate
contact with the mechanical rotation stop.
Swing Speed Adjustment – Located on turn motor inside
frame. Turn knob in to increase maximum swing speed. Turn
knob out to decrease maximum swing speed.
Boom – Operate the lever to DOWN to lower the boom.
Operate the lever to UP to raise the boom.
Boom Telescope – Operate the lever to OUT to extend the
boom. Operate the lever to IN to retract the boom.
Hoist – Operate the lever to DOWN to payout and lower the
loadline. Operate the lever to UP to reel in and raise the
loadline. Refer to hoist system operation section for
additional information.
Payout loadline before extending boom. Failure to do so
may cause the loadline to break or damage the crane.
Stabilizers – Up/Down – Operate the lever to DOWN to
lower and UP to raise.
Stabilizers – Extend/Retract – Operate the lever to
EXTEND to move beams out and to RETRACT to move
beams in.
Outriggers – Operate the lever to UP to raise the outrigger
legs. Operate the lever to DOWN to lower the outrigger legs.
Foot Throttle – Depress the foot throttle to accelerate the
truck engine speed. Release to return to idle speed.
Increasing truck speed increases operating speed.
Engine Emergency Stop Switch – Operate the switch to
stop the truck engine under emergency conditions. Switch
must be reset to on to operate truck from cab.
Horn – Operate horn button to warn fellow workers on
construction site of pending movement of crane.
Pressure Gauge – Observe pressure gauge while booming
up or down at end of stroke to determine system pressure.
Note: RCL required on cranes with jibs and/or personnel
platforms.
RCL Display Console – Acts as interface between
operation and load moment system. It’s used to import
operating conditions and display boom and load information.
Refer to RCL manual.
RCL CPU – Processes load information to give operator
crane capacities and boom information. Refer to RCL
manual in this owners manual.
ATB Light – Indicator light illuminates when a two block
condition is detected.
Override Key Switch – The Override Key Switch
continuously overrides HCA/ATB lockout conditions in
emergency situations. When the key switch is turned to the
ON position, the system overrides HCA/ATB lockout
condition until the key is turned to the OFF position. Some
units may be equipped with a Manual Reset Valve option that
does not have Override Key Switch. Do not use override to
continue lifting operations in an overload or two blocked
condition.
