(continued)

OPERATING PROCEDURE
1. Moving Lift to Work Area
(No Load)
The lift is normally moved to the job site
by rolling on its four caster wheels. Note:
Do not pull by the load lifting cable.
IMPORTANT Before tilting unit to reclined
position, the carriage must be in the down
position below the red arrows, and ensure
that the safety latch is engaged.
To Tilt the unit into position for transport;
from a squatting position, grasp the legs
just past the front casters and while keep-
ing your back straight, lift upwards to a
standing position while someone supports
the unit from behind. The unit is now
ready to transport.
2. Moving Lift in Work Area
(With Load)
Although it is best to move the unit to the
job site unloaded, light loads may be
transported as long as the stabilizer legs
are installed and the unit is rolled on the
eight caster wheels and on a level sur-
face. Always have the load in the lowest
possible position before moving the unit.
If it is necessary to move the unit with an
elevated load:
 Make sure the area is clear of obstruc-
tions
 Keep personnel away from the load
and behind the operator’s position.
 Move the unit slowly, avoiding sudden
jerky starts and stops
 Make sure the load is secure and prop-
erly balanced Note load capacity at
given centers below.
 Make sure the stabilizer legs are in-
stalled and locked into position.
7
CAUTION
Always use proper lifting techniques.
CAUTION
If a load is being transported,
it should be secured to the fork
to avoid shifting.
WARNING
Moving the unit with elevated loads
should be contained to short
distances; i.e., 10-15 feet/4-5 meters.
WARNING
Do not extend load centers beyond
fork ends by modifying the lift.
Lift may become unstable.

Before each use:
1. Inspect the cable for kinks and frays. If kinked
or more than 3 wire strands are broken (small
wires) do not use the lift until the cable has
been replaced.
2. Make certain winch operates freely and cable
is not tangled on the winch drum.
3. Check forks, legs, and base for bends.
4. Make sure caster wheels move freely.
5. Make sure stabilizer legs slide freely into
mounting sockets and plunger pins lock legs
into position.
6. Check to ensure that leveling screws turn eas-
ily.
Recommended Inspection Every 6 Months:
1. Inspect cable for frays and kinks (see point 1
above)
2. Make certain winch works freely and that there
are no loose or damaged parts.
3. Brake Inspections
4. Manually raise and support each movable
mast section and carriage a minimum of 6”
above their lowest position. Use a wooden
block with a rope attached to the bottom end to
quickly pull on rope to remove wooden block
support from mast sections being tested.
Brakes should engage before mast section
reaches bottom stop. Use winch to crank up
mast sections to release the safety brakes.
Winch Maintenance:
1. Refer to the winch assembly drawings in this
Operators Manual.
2. Be sure that both winch covers are on the
winch.
3. Check ratchet dog and brake ratchet for wear.
If any wear is visible, replace the part. If not,
lubricate the holes in both parts with a light oil.
4. Inspect gear teeth for wear. If there is no sign
of visible wear, brush teeth with 50-wt. Motor
oil.
5. For proper brake adjustment see
“Troubleshooting” section on page 19.
Replacing the Cable:
1. Lower the carriage to engage the safety latch.
2. Remove the large gear cover from the winch
3. Unwind the cable from the load drum, loosen
the set screw and remove the cable.
4. Unbolt the cable from the top of the top mast.
5. Cut the looped end off the old cable assembly,
using cable cutters or a cutting torch.
6. Fusion weld the plain end of the new cable to
the cut end of the cable. Note: The fused
joint must be straight and smooth or it will
not pass through the pulley assemblies
inside the unit.
7. Use the winch to pull the old cable from the
winch side while feeding the new cable
through the carriage until the old cable is
completely out of the unit. Cut the cables
apart approximately 2” from the weld on the
new cable and fuse the end of the new cable
to prevent unraveling.
8. Bolt the new cable (looped end) to the top of
the top mast.
9. Thread the plain end of the cable through the
drum into the roper keeper and tighten the set
screw. Note: The cable must be fed from
the bottom of the winch between the winch
and the mast sections, over the drum and
into the slot on the wide plate.
10. Wind the slack cable tightly and evenly across
the load drum.
11. Replace the winch covers.

MAINTENANCE INSTRUCTIONS
old cable new cable
Trim all loose strands before pulling cable
through unit. Make sure that welded area is not
too bulky to pass between the rope guards and
pulley wheels.

General Maintenance:
1. Check both winch handles for wear or bends.
2. Inspect 3” roller wheels mounted on the winch
and top mast for damage and smooth rotation.
3. Examine all bolts and nuts to be sure they are
tight.
4. Legs, forks, braces and base should be dent
free and damage free.
5. Check pulley covers for damage (indentations)
which can restrict the rotation of the pulleys.
6. Make sure load line is seated in all pulleys and
that pulley rotates without obstruction.
7. Make sure stabilizer legs slide freely into
mounting sockets and plunger pins lock legs
into position.
8. Check all roller wheels for free rotation.
9. Inspect masts and carriage hold-down device.
10. Raise mast sections to inspect for free,
smooth sliding action. Make sure wire slide-
ways are free of dust and oxidation and spray
a light coat of silicone lubrication in slideways.
11. Make sure all caster wheels rotate freely and
are undamaged.
12. Inspect all plunger mechanisms and apply
light grease as required.
13. Check to be sure that all three mast covers are
attached to the lift.
14. Check the safety brake operation.
Safety Brake Maintenance:
The safety brake will automatically engage when
the unit is horizontal, preventing disassembly of
the mast sections. When this occurs, the masts
will extend, but not retract. A special tool which
can be found in the Operator’s Manual tube is re-
quired to release the brakes and disassemble the
unit. If the tool is lost or damaged, one can be
made simply from a piece of 1/8 to 1/4 inch diame-
ter steel rod 9 inches long, with both ends bent
into an “L” shape 1-1/4” long.
To release the brake, place the tool in the right
side (looking at the lift from the bottom) of the mast
assembly (or carriage) as shown, into the access
slot and through the hole in the counterweight.
Pull the hook tool toward you and the brake will be
released.
It may be necessary to push the locked mast (or
carriage) up slightly while pulling on the tool.
Once the brake is released, maintain pressure on
the tool and slide the mast sections (or carriage)
apart.
Repeat this step for each mast section.
