the system when switching fuels. If the machine is
to be operated on propane, open the supply valve
on the tank.

Note: When using LP gas, use clean, water free liquid
petroleum gas, preferably from a bulk storage tank.
Follow the instructions located on the power module
tray for filling the tank.

.

PLATFORM

If you smell propane, close the supply valve
on the tank immediately until you have
located and corrected the leak.

12. While the engine is cool check the engine coolant
level.

DO NOT check coolant when engine or
radiator is hot, hot coolant can cause severe
burns.

System Function Inspection

STAND CLEAR of the work platform while
performing the following checks.

Before operating the work platform survey
the work area for surface hazards such as
holes, drop-offs, bumps and debris.

Check in ALL directions, including above the
work platform, for obstructions and electrical
conductors.

Protect control console cable from possible
damage while performing checks.

Operation

Before operating work platform, ensure that the pre­operation and safety inspection has been completed,
any deficiencies have been corrected and the opera­tor has been thoroughly trained on this machine.

Travel With Platform Lowered

1. Verify chassis emergency stop switch is in the
ON position (turn counterclockwise), the drive
enable indicator is on, and that the platform/
chassis switch is on PLATFORM.

Note: If the drive enable indicator is off, verify
that the platform is fully lowered.

2. After mounting platform, secure the chain (close
and latch gate on Euro machines). 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
position.

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 models, depress and hold
the glow plug button for 6 seconds to engage the
glow plugs.

7. Set the drive speed range switch to;
2-wheel drive - HIGH TORQUE
4-wheel drive - Middle Position.

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 direction. 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.

10. On 4-wheel drive machines, use HIGH TORQUE
position for steep grades or muddy conditions
where more torque is required.

Steering

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.

Raising and Lowering the Platform

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.

3. When the work task is completed, position the
drive/lift switch to LIFT and lower the platform
by pulling back on the control lever until the
platform is fully lowered.

Travel with Work Platform Elevated

Travel with platform elevated ONLY on firm and
level surfaces.

Note: The work platform will travel at reduced
speed when in the elevated position.

1. Check that the route is clear of persons, obstruc­tions, holes and drop-offs, is level and capable of
supporting the wheel loads.

2. Check clearances above, below and to the sides of
platform.

3. Position the drive/lift switch to the DRIVE
position.

4. Push the control lever to FORWARD or RE-

VERSE for the desired direction of travel.

If the machine quits driving and the tilt alarm
sounds, immediately lower the platform and move
the machine to a level location before re-elevating
the platform.
