TMS800E OPERATOR’S MANUAL
OPERATING CONTROLS AND PROCEDURES
Lowering the Boom
Retracting The Boom (With Single Hoist) (Optional)
To lower the boom, push the controller on the right hand armrest to the right and hold until the boom is lowered to the desired position.
WARNING When retracting the boom, the load will lower unless the cable is taken in at the same time.
WARNING Long cantilever booms can create a tipping condition even when unloaded and in an extended and lowered position.
To retract the boom, push the controller 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.
DANGER Lower boom and let out cable simultaneously to prevent two-blocking.
Lowering And Raising The Hoist Cable
CAUTION
WARNING
The closer the load is to the boom nose, the more important it becomes to let out cable as the boom is lowered.
Keep the area beneath the load clear of all obstructions and personnel when lowering or raising the cable (load).
Telescoping The Boom NOTE:
When the crane is equipped with an auxiliary hoist the telescope function is controlled by a foot pedal.
Extending The Boom (With Single Hoist) (Optional)
WARNING Do not jerk controller when starting or stopping hoist. Jerking causes load to bounce, which could result in possible damage to the crane. NOTE:
WARNING When extending the boom, simultaneously let out the cable to prevent two-blocking the boom nose and hook block.
When the load is stopped at the desired height, the automatic brake will engage and hold the load as long as the controller remains in neutral.
Lowering The Cable Push the main hoist (right hand armrest) or auxiliary hoist (left hand armrest) controller forward, away from the operator, and hold until the hook or load is lowered to the desired height.
DANGER Check the load chart for maximum load at given radius, boom angle, and length before extending boom with a load. Push the controller on the left hand armrest to the left, and hold until the boom reaches the desired length.
GROVE
Raising the Cable Pull the main hoist (right hand armrest) or auxiliary hoist (left hand armrest) controller, toward the operator, and hold until the hook or load is raised to the desired height.
