Published 02-06-2014, Control # 495-00
Lowering the Boom (Dual Axis Option—Not Shown)
To lower the boom, push the joystick on the right hand
armrest to the right and hold until the boom is lowered to the
desired position.
Telescoping the Boom
NOTE:
When the crane is equipped with an auxiliary hoist
the telescope function is controlled by a foot pedal.
Telescope or Auxiliary Hoist Joystick (Single Axis)
The Telescope or Auxiliary Hoist (TELE or AUX) Joystick is
located on the left armrest. The joystick controls the
telescope functions when the crane is not equipped with an
auxiliary hoist. Push the joystick forward to telescope the
boom out, or pull the joystick back to telescope boom in.
When equipped with an auxiliary hoist, the joystick controls
the auxiliary hoist functions and the telescope functions are
controlled through a foot pedal. Push the joystick forward to
let out the hoist cable or pull the joystick back to reel the
cable in.
Extending the Boom (Dual Axis Option with Single
Hoist)
Push the joystick on the left hand armrest to the left, and hold
until the boom reaches the desired length.
Retracting the Boom (Dual Axis Option with Single
Hoist)
To retract the boom, push the joystick on the left hand
armrest to the right and hold until the boom retracts to the
desired position.
Telescope Control Pedal
The telescope control pedal is used on cranes equipped with
an auxiliary hoist. Push on the top of the pedal to extend the
boom and push on the bottom of the pedal to retract the
boom.
Lowering and Raising the Hoist Cable
NOTE:
When the load is stopped at the desired height, the
automatic brake will engage and hold the load as
long as the joystick remains in neutral.
Lowering the Cable
Push the main hoist (right hand armrest) or auxiliary hoist
(left hand armrest) joystick forward, away from the operator,
and hold until the hook or load is lowered to the desired
height.
WARNING
Long cantilever booms can create a tipping condition
even when unloaded and in an extended and lowered
position.
WARNING
Lower boom and let out cable simultaneously to prevent
two-blocking.
CAUTION
The closer the load is to the boom nose, the more
important it becomes to let out cable as the boom is
lowered.
WARNING
When extending the boom, simultaneously let out the
cable to prevent two-blocking the boom nose and hook
block.
DANGER
Check the load chart for maximum load at given radius,
boom angle, and length before extending boom with a
load.
WARNING
When retracting the boom, the load will lower unless the
cable is taken in at the same time.
WARNING
Keep the area beneath the load clear of all obstructions
and personnel when lowering or raising the cable (load).
WARNING
Do not jerk joystick when starting or stopping hoist.
Jerking causes load to bounce, which could result in
possible damage to the crane.
