EMERGENCY OPERATION
In the event of powered function failure, the elevating
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. Operate the emergency control pump four full
strokes to release brakes.
5. After moving the machine, return the keyswitch to
the off position and remove the key to prevent
unauthorized operation. Brakes are now reset. Alarm
will stop.
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.
