EMERGENCY OPERATION
In the event of powered function failure, the elevat-
ing assembly may be lowered manually by the
following procedure.
NEVER climb down the elevating assembly.
If controls do not respond, ask someone on
the ground to lower the boom manually.
Lowering Elevating Assembly
1. Open the cover on the hydraulic module (opposite
side of the turret from the chassis control panel).
2. Remove the wire loop retainer from the hand
pump lever, and extend the handle upward to
gain leverage.
3. Operate the manual override (knurled knob) on the
appropriate valve (see fig. 4). Push in to lower /
extend, pull out to raise / retract as required.
4. While holding the appropriate valve in position,
pump the handle in and out until that section of
the elevating assembly is lowered / retracted.
5. Repeat as necessary operating each valve until
the elevating assembly is fully lowered.
Rotating Turret
1. Obtain a 7 /
8
inch ratcheting wrench.
2. Place the socket of the wrench onto the hex shaft
stub of the turret rotation gearbox.
3. Turn the wrench clockwise to rotate the turret
counterclockwise, turn counterclockwise to rotate
the turret clockwise.
EMERGENCY TOWING
Perform the following only when the machine will not
operate under its own power and it is necessary to
move the machine or when winching onto a trailer
for transportation.
The batteries must be connected to release the
brakes.
1. Insure that the platform is fully lowered, and that
the turret is rotated so the platform is to the rear
of the machine.
2. Attach chain / cable of sufficient strength for
towing the machine to front or rear tie down lugs.
3. Turn the keyswitch to the parking brake release
position. Alarm will sound.
4. Depress the electric motor start switch and hold
for 2 seconds, release.
5. After moving the machine, return the keyswitch to
the off position and remove the key to prevent
unauthorized operation.
DO NOT move the machine faster than
3 mph. Faster speeds will damage drive
components and void warranty.
AFTER USE EACH DAY
1. Ensure that the platform is fully lowered.
2. Park the machine on level ground, preferably
under cover, secure against vandals, children or
unauthorized operation.
3. Turn the key switch to OFF and remove all keys
to prevent unauthorized operation.
