Introduction

This manual covers SL-26/30 Narrow Work Plat­forms. This manual must be stored on the

machine at all times.

Electric Model inspection

1. Verify batteries are charged (see Battery
Maintenance, page 6).

2. Check that A.C. extension cord has been
disconnected from charger.

Pre-Operation and Safety

Inspection

Read, understand and follow all safety rules
and operating instructions and then perform
the following steps each day before use.

1. Remove module covers and inspect for dam­age, oil leaks or missing parts.

2. Check the level of the hydraulic oil with the
platform fully lowered. Oil should be visible in
the sight gauge. Add hydraulic oil, if necessary
(see Specifications, back cover).

3. Check that the fluid level in the batteries is
correct (see Battery Maintenance, page 6).

4. Carefully inspect the entire work platform for
damage such as cracked welds or structural
members, loose or missing parts, oil leaks,
damaged cables or hoses, loose connections
and tire damage.

5. Check that all guardrails are securely in place
with all fasteners properly torqued.

6. Check tire pressure (50 psi).

7. Place the Chassis Emergency Stop Switch to
the ON position.

Gas / Propane Model Inspection

1. Check fuel supply.

2. Check engine oil level with dipstick.

3. If equipped, check coolant level in radiator.
DO NOT check coolant when radiator or
engine is hot.

4. Set gasoline / propane selector to desired
position. Set to the center position to purge 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.

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.

1. Unhook Controller from front guardrail. Firmly
grasp Controller hanger in such a manner that
the Interlock Lever can be depressed, while
performing the following checks from the
ground.

2. Pull Controller Emergency Stop Button out to
ON position.

3. Turn Controller Key Switch clockwise to ON.
Turn fully clockwise to start engine (Gasoline /
Propane engine only).

Note: If the engine is cold, depress the choke
button and hold while starting. Diesel mod­els: depress and hold the glow plug button
for 6 seconds prior to starting to engage the
glow plugs.

4. Turn Drive/Lift Switch to DRIVE position.

5. With the Speed Range Switch first in HIGH
TORQUE and then in HIGH SPEED actuate
the Interlock Lever and slowly push the Control
Lever to FORWARD then REVERSE positions
to check for speed and directional control. The
farther you push or pull the Control Lever from
center the faster the machine will travel.

6. Push Steering Switch RIGHT then LEFT to
check for steering control.

7. Rehook Controller on front guardrail.

8. Push Chassis Lift Switch to UP position and
elevate platform while pushing the Tilt Sensor
off of level. The platform should only elevate
about one foot (.3 m) and the Tilt Alarm should
sound. If the platform continues to elevate and/
or there is no alarm STOP and remove the
machine from service until it is repaired.

9. Release the Tilt Sensor and fully elevate
platform.

10. Visually inspect the elevating assembly, lift
cylinder, cables and hoses for damage or
erratic operation. Check for missing or loose
parts.

11. Lower the platform partially by pushing Chas­sis Lift Switch to DOWN, and check operation
of the audible lowering alarm.

12. Open the Chassis Emergency Lowering Valve,
push in and turn counterclockwise, to check for
proper operation. Once the platform is fully
lowered, close the valve, push in and turn
clockwise until the detent engages.

13. Close and secure module covers.

14. Turn the Controller Key Switch counterclock­wise to OFF.

Operation

Before operating work platform, ensure that the
pre-operation 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.

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 position.

6. Set the Drive/Lift Switch to the DRIVE position
and turn the Key Switch to ON. On Gasoline /
Propane models, start the engine.

Note: If the engine is cold, depress the choke
button and hold while starting. Diesel models:
depress and hold the glow plug button for 6 sec­onds prior to starting to engage 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 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.

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. Push-
ing 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 and is 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

REVERSE for the desired direction of travel.

Emergency Lowering

The Emergency Lowering Valve is located on
the left hand side of the chassis through the
cutout in the Control Module cover.

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 the
key to prevent unauthorized operation.

Parking Brake Release (Figure 3)

Perform the following only when the machine will
not operate under its own power and it is neces­sary to move the machine or when towing the
machine up a grade or winching onto a trailer to
transport.

1. Close the needle valve by turning the knob
clockwise.

2. Pump the Brake Release Pump until the Parking
Brake Cylinder Rod clears the wheel rotor.

3. The machine will now roll when pushed or pulled.

4. Be sure to open the needle valve and verify
that the cylinder rod has extended before the
machine is operated.

Never operate work platform with the
Parking Brake inoperative. Serious injury or
damage could result.

Never tow faster than 1 ft./sec. (.3 m/sec).

1. Open the Emergency Lowering Valve by
pushing in and turning the knob counterclock­wise approximately ¼ turn, the knob will pop
out disengaging detent.

2. Once the platform is fully lowered, be certain
that the Emergency Lowering Valve is closed
again. The platform will not elevate if the
Emergency Lowering Valve has not been
closed.

3. To close the Emergency Lowering Valve, push
the knob in and turn approximately ¼ turn
clockwise until the detent engages.

Switching Fuels (Gas / Propane Only)

1. With engine running push the Fuel Selector
Switch to the center position.

2. After the engine has quit running select the
appropriate fuel supply.

3. Restart the engine.
