LOADING
1. Raise the loader support brackets and engage the retaining pin in the top hole of the loader
channel.
2. Secure the loader to the loader support bracket with the gravity hook.
3. Position the unit so that the back of the machine comes into contact with the tailgate or vehicle
bed.
4. Release the gravity hook and slide the loader down until it comes into contact with the tailgate
or vehicle bed. Then, re-position the loader support bracket so that the retaining pin is in the
rst available hole above the loader.
5. Release the locking pin and pull the T-handle out until the locking pin engages the hole in the
end of the T-handle.
6. Lift up on the T-handle using the loader as a pivot until the unit rotates to a horizontal position
in the vehicle bed.
7. Push the base of the unit towards the front of the vehicle bed. The machine will slide on the
loader until the rear wheels are on the bed. The unit may then be rolled on the rear wheels and
upper casters.
8. Re-turn the T-handle to the stored position making sure that the locking pin engages the Thandle.
9. Secure the unit with suitable tie straps using the forklift pockets located under the base of the
tilt back frame.

C A U T I O N
!
To prevent damage to the mast assembly, do not place
rope or tie straps across the mast assembly when secur-
ing the unit for transportation.
DO NOT overtighten the rope or tie straps otherwise
damage to the machine will result.
UNLOADING
1. Unsecure the unit.
2. Release the locking pin and pull the T-handle out until the locking pin engages the hole at the
end of the T-handle.
3. Roll the unit back until the rear wheels are off the edge of the tailgate or vehicle bed.
4. Pull downward on the T-handle allowing the unit to slide on the loader.
• As the unit stops sliding on the loader, it will pivot on the loader to an upright position.
• Gradually counterbalance the unit’s weight by applying an upward force on the T-handle.
This allows the unit to settle gently on the wheels avoiding undue impact on the unit.
5. Return the T-handle to the stored position making sure that the locking pin engages the T-handle.

PASSAGE THROUGH A DOORWAY
The UL machine is equipped with a castered rear tilt back assembly. When the unit is tilted back
onto this support frame, the overall height is reduced to allow the unit to pass through a standard
doorway.
LOWERING
!
C A U T I O N
!
Before tilting the machine unto the rear tilt back as-
sembly, be sure that the retaining pin is fully inserted
with the hair pin retainer and the cylinder assembly is
fully extended.
DO NOT drop the tilt back frame. Keep out from under
the tilt back frame and machine when tilting.
1. Ensure that the area is clear of personnel and obstructions.
2. While holding the tilt back frame, remove the hair pin retainer and the retaining pin.
3. Lower the tilt back frame until the hole in the cylinder assembly align with the upper mounting
bracket pin hole. Secure the cylinder assembly to the upper mounting bracket using the retaining pin and hair pin retainer.
4. Extend the tilt back handle to the tilt/lift position by releasing the locking pin and pulling the
handle out of the tilt back assembly until the locking pin engages.
5. Push down on the tilt back handle until the unit comes to rest on the tilt back frame.
• As the mast tilts back, counterbalance the machine’s weight by increasing upward force
on the end of the tilt back handle. This allows the machine to gently come to rest on the tilt
back casters.
6. Pull down on the handle on the back of the mast to compress the cylinder assembly.
7. Return the tilt back handle to the storage position, making sure that the locking pin engages
the handle.
RAISING
1. Lift up on the mast handle to extend the cylinder assembly.
2. Fully engage the tilt back handle until the locking pin engages.
3. Lift up on the tilt back handle.
• As the mast approaches vertical, counterbalance the machine’s weight by increasing
downward force on the end of the tilt back handle. This allows the machine to settle gently
on the front casters.
4. Return the tilt back handle to the storage position, making sure that the locking pin engages
the handle.
5. While holding the tilt back frame, remove the retaining pin and raise the tilt back assembly to
the stowed position.
6. Secure with the retaining pin, making sure that the retaining pin is fully inserted and that the
hair pin retainer is installed.

Hazard of explosive gas mixture. Keep sparks, ame and smoking
material away from batteries.
Always wear safety glasses when working near batteries.
Battery uid is highly corrosive. Thoroughly rinse away any spilled uid with
clean water.
Always replace the batteries with Snorkel batteries or manufacturer approved replacements weighing 22 kg (48 lbs.) each.
Use the following procedure to ensure battery maintenance.
1. Check the battery uid level daily especially if the work platform is being used in a warm, dry
climate.
2. If the electrolyte level is lower than 10 mm (3/8") above the plates, add distilled water only. Do
not use tap water due to its high mineral content since it will shorten battery life.
3. Keep the terminals and tops of the batteries clean.
4. Refer to the service manual to extend battery life and for complete service instructions.
BATTERY CHARGING
!
W A R N I N G
!
Charge the batteries in a well ventilated area. Do not charge the batteries when
the work platform is near a source of spark or ames.
Permanent damage to the batteries will result if the batteries are not
immediately recharged after discharging. Never disconnect the cables from the
batteries when the charger is operating. Keep the charger dry.
Use the following procedure to charge the batteries after use.
1. Check the battery uid level. If the battery uid level is lower than 10 mm (3/8") above the
plates, add distilled water only.
2. Verify the charger voltage switch is set to 12 volts.
3. Connect an appropriate extension cord to the charger plug. Plug the extension cord into a
properly grounded outlet of proper voltage and frequency.
NOTE: The battery charger circuit must be used with a GFI (Ground fault interrupt) outlet.
NOTE: Do not operate the machine while the charger is plugged in.
