SECTION 4 - MACHINE OPERATION
4-4 – JLG Sizzor – 3121100
TRAVEL GRADES IN “LOW” DRIVE SPEED ONLY. USE EXTREME
CAUTION WHEN DRIVING IN REVERSE AND AT ALL TIMES WHEN
DRIVING WITH PLATFORM ELEVATED AND ESPECIALLY WHEN
DRIVING WITH ANY PART OF MACHINE WITHIN 6 FEET (2 M) OF
AN OBSTRUCTION.
HIGH DRIVE SPEED IS CUT OUT WHEN PLATFORM IS RAISED
ABOVE STOWED POSITION. IF LIMIT SWITCH MALFUNCTIONS,
SHUT DOWN MACHINE AND HAVE AUTHORIZED SERVICE PER-
SONNEL REPAIR OR REPLACE LIMIT SWITCH PRIOR TO RESUM-
ING OPERATION.
THE 500RTS IS EQUIPPED WITH A 2 DEGREES TILT SWITCH
THAT ILLUMINATES A LIGHT ON THE PLATFORM CONTROL
CONSOLE AND SOUNDS AN AUDIBLE ALARM WHEN THE
MACHINE IS ON A SLOPE (OVER 2 DEGREES) WITH THE PLAT-
FORM RAISED. WHEN MACHINE IS ON A SLOPE (OVER 2
DEGREES) WITH THE PLATFORM COMPLETELY LOWERED,
ONLY THE WARNING LIGHT IS ILLUMINATED.
Traveling Forward
NOTE: On machines equipped with leveling jacks, leveling
jacks must be in the stowed position before opera-
tion of the drive system.
1. Position ignition/emergency stop switch to on. If
machine has been shut down, start engine and
allow warm-up period before beginning any lifting.
2. Position pump and engine control switches to
desired positions (high or low) and position drive
control switch to desired position (torque or speed).
3. Position controller to forward, squeeze red trigger
switch on the front of the controller, and hold con-
troller in position for duration of travel. The red trig-
ger switch must be depressed for the duration of
travel. Drive speed is determined by the distance the
controller is moved from the center off position.
Traveling in Reverse
NOTE: On machines equipped with leveling jacks, leveling
jacks must be in the stowed position before opera-
tion of the drive system.
1. Position ignition/emergency stop switch to on. If

4.8 PARKING AND STOWING
Park and stow machine as follows:
1. Drive machine to a reasonably well-protected and
well-ventilated area.
2. Ensure platform is fully lowered.
3. Position emergency stop switch to off position.
4. If necessary, cover the instruction placards, caution
and warning decals so that they will be protected
from hostile environment.
5. Chock at least two wheels when parking machine for
an extended period of time.
6. Turn ignition/emergency stop switch to off and turn
the Power selector switch to the center position and
remove key to disable machine from unauthorized
use.
4.9 PLATFORM LOADING
The platform maximum rated load capacity is shown on a
placard located on the platform and is based upon the fol-
lowing criteria.
1. Machine is positioned on a smooth, firm and level
surface.
2. All braking devices are engaged.
3. Refer to Section 3 for platform capacities.
4. Leveling Jacks properly set.
It is important to remember that the load should be evenly
distributed on the platform. The load should be placed
near the center of the platform when possible.
