99903514: TELESCOPIC CRANE: 1-8 SECTION 1: OPERATION
1-6-5: ELECTRIC CRANES
Electric cranes have no PTO or pumps, but
they do have tethered remote controls which are
similar in operation to the hydraulically controlled
cranes.
The telescopic remote controls operate the
crane boom extensions, crane rotation, winch,
engine speed, and crane and compressor
power. The remote controls also have an
ENGINE STOP function which is a safety
feature required on all cranes with remote
controls that use a PTO driven pump.
To operate the crane,
1) Turn on the power via the on/off switch of
the tethered remote handle. Press the “Engine
Start” toggle to start the vehicle engine to power
the crane.
2) Pull back on the trigger until the power unit
begins to run.
3) Using the decal as a guide, select the
required function on the crane handle to move
the crane as desired, making sure not to
release tension on the trigger assembly. You
must hold both the trigger and the crane
function toggle switch at the same time to make
the crane move.
4) When done with the function, continue to
hold the trigger assembly in until all immediate
movements of the crane have been completed.
5) If no further work with the crane is needed,
or if all immediate movements of the crane
have been completed, then release the trigger
assembly to return the power unit back to a
rested state.
6) Turn off power to the handset.
NOTE
EXCESSIVE OR RAPID “ON/OFF” CY-
CLING OF THE TRIGGER ASSEMBLY
SHOULD BE AVOIDED, PARTICULARLY IF
A FUNCTION IS ENGAGED. THIS WILL
CAUSE PREMATURE AGING OR EXTEN-
SIVE DAMAGE TO THE POWER UNIT
COMPONENTS.
Although you should not rapidly cycle the trigger,
which turns the motor on and off, you can cycle
the toggle switch to control the working speed of
the crane.
