O PERATION
NOTE: Before operating work platform,
ensure that the pre-operation and safety
inspection has been completed, any defi-
ciencies have been corrected and the oper-
ator has been thoroughly trained on this
machine.
T RAVEL W ITH P LATFORM L OWERED
1. Verify chassis emergency stop switch is in the ON posi-
tion (turn counterclockwise), the drive enable indicator
is on, and that the platform/chassis switch is on PLAT-
FORM.
Note: If the drive enable indicator is off, ver-
ify that the platform is fully lowered and (if
so equipped) the outriggers are fully
retracted.
2. After mounting platform, close and latch gate. Check
that guardrails are in position and properly assembled
with fasteners properly torqued.
3. Check that route is clear of persons, obstructions,
holes and drop-offs and is capable of supporting the
wheel loads.
4. Check clearances above, below and to the sides of the
platform.
5. Pull controller emergency stop button out to ON posi-
tion.
6. Turn controller key switch fully clockwise to start
engine, releasing the key once the engine starts.
Note: If the engine is cold, on dual fuel
models, depress and hold the choke button
in while starting the engine. On diesel mod-
els, hold the glow plug button in for 6 sec-
onds to heat the glow plugs.
7. Set the drive/lift speed range switch to HIGH TORQUE.
8. Grasp the control lever so the interlock lever is
depressed (releasing the interlock lever cuts power to
controller). Slowly push or pull the control lever to
FORWARD or REVERSE to travel in the desired direc-
tion. The farther you push or pull the control lever from
center the faster the machine will travel.
9. While moving, push the drive/lift speed range switch to
HIGH SPEED for travel on level surfaces or to HIGH
TORQUE for climbing grades or traveling in confined
areas.
S TEERING
1. Push the steering switch RIGHT or LEFT to turn the
wheels. Observe the tires while maneuvering to insure
proper direction.
NOTE: Steering is not self-centering.
Wheels must be returned to the straight
ahead position by operating the steering
switch.
L EVELING THE P LATFORM (O UTRIG -
GER EQUIPPED MACHINES ONLY )
1. Look around the machine, make sure that there is noth-
ing obstructing the outriggers, and that the surface
beneath them is suitable to support the weight of the
machine.
2. Depress the interlock lever on the control handle and
operate the outrigger switches to extend each outrigger
until it is making firm contact with the ground.
3. While observing the bubble level on the front guardrail,
(Figure 3), extend the outrigger opposite the position of
the bubble until the platform is level. For example: if the
bubble is to the front and left in the orbit, extend the
rear right outrigger. Continue to adjust until the bubble
is centered in the small circle indicating that the plat-
form is level.
4. Outriggers must be in firm contact with the supporting
surface, observe each outrigger to verify.
T O R ETRACT THE OUTRIGGERS
1. Fully lower the platform.
2. Position each outrigger switch to RETRACT. Observe
the outriggers to ensure that they are fully retracted.
The drive enable indicator light will not come on until all
four outriggers are fully retracted.

R AISING AND L OWERING THE P LAT -
FORM
1. Position the drive/lift switch to LIFT.
2. While holding the control lever so the interlock lever is
depressed, push the control lever slowly to UP to raise
the platform. Pushing the control lever farther
increases the lift speed.
Never operate work platform with the parking
brakes released. Serious injury or damage
could result.
