1-6-2: CHANGING THE BATTERY IN THE
RADIO REMOTE CONTROL
A button on the bottom of the radio remote
handset closes the battery compartment. Slide
the button toward the back of the handset, and
the battery compartment will open.
Remove the battery and replace with a charged
battery to continue operation.
Your telescopic crane comes with two re-
chargeable batteries as well as a charging unit
which plugs into the cigarette lighter of your
vehicle.
1-6-3: RADIO REMOTE BACKUP HAND-
SET
Each telescopic crane equipped with a radio
remote control also has a tethered backup in
case the radio fails.
To activate the backup handset, plug the hand-
set into 15-pin connection, labeled J17, located
at the base of the crane, behind the controls
valve bank shield. See Figure A-8 for the con-
nection location.
The backup handset is not proportional. When
the backup handset is plugged into the connec-
tor, it receives full flow.
1-6-4: TETHERED REMOTE CONTROLS
Your crane may come with a tethered rather
than a radio remote control. Tethered remote
controls are similar in operation to radio remote
controls with a few exceptions. To operate a
tethered remote:
1) Turn the power switch to “Crane”.
2) Turn the engine speed to “Fast”. Use “Fast”
for full hydraulic pressure, and use “Idle” when
the crane is on but not working.
3) Toggle and hold switches to the desired
position, and pull the trigger to move the crane.
4) When finished, return the crane to transport
position. See Section 1-10 for the crane shut-
down procedure.
Cranes with tethered remotes do not have
backup handsets.
