2. WORK AREA HAZARDS
(continued)

OPERATING PROCEDURE
1. Unpacking the Lift
Remove the lift from the shipping pallet by
cutting the bands and rocking the lift back
on the 8” transportation wheels. Carefully
roll the lift back off of the pallet onto a
smooth, level surface. Place the lift back
into it’s upright stored position.
The lift has been shipped with the Mast
Hold Down
Strap en-
gaged. The
purpose of
the Mast
Hold Down,
is to keep the
mast sec-
tions from
extending
during transportation. To use your lift, dis-
connect the Safety Latch attached to the
carriage.
2. 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 and the mast hold down strap must
be 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.
3. Moving Lift in Work Area
(With Load)
Although it is best to move the unit to the
job site unloaded, light loads may be trans-
ported as long as the stabilizer legs are in-
stalled and the unit is rolled on the eight
caster wheels and on a level surface. Al-
ways have the load in the lowest possible
position before moving the unit.
7
CAUTION
Always use proper lifting techniques.
CAUTION
If a load is being transported,
it should be secured to the fork
to avoid shifting.
The winch handles
have been placed in
the stored position.
To place the winch
handles in the oper-
ating position, pull up
on the locking pin
and slide the handle
off of the winch
shaft. Rotate the
handle assembly
around so that the
black plastic grip is
facing away from the
winch. While pulling
up on the locking
pin, slide the handle
back on to the winch
shaft. Repeat this
procedure for the
other handle.
When properly in-
stalled, the winch han-
dles should be
mounted 180 degrees
apart, as shown in the
picture. Do not attempt to raise or
lower a load with the handles
mounted in any other manner.

8
OPERATING PROCEDURE (continued)
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.
4. Reversing the Forks
Disengage 2 spring-loaded pins. Rotate
fork assembly 180 degrees. Engage the 2
spring-loaded pins.
Reverse step #4 to return the forks to their
normal position.
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.

5. Lifting and Lowering Loads
Use the winch to crank forks up or down
into the desired position. Then crank
winch handles up about 1/4 turn to set the
safety brake.
Any unstable load must be balanced and
secured to the forks prior to lifting.
Turn winch crank clockwise to elevate the
load, while watching for overhead obstruc-
tions.
After load is removed from the forks, lower
masts by turning winch crank counter
clockwise.
Lock caster brakes when leaving unit
unattended.
6. Storing Forks
Using two hands, pull out on the two
spring-loaded rings located above the fork
arms. Slide the fork assembly up off of the
carriage while pulling out the rings. The
fork can be placed behind the lift for stor-
age.
Lift may be stored in the upright, compact
position.

CAUTION
Make sure the floor surface is level.
WARNING
No riders allowed on this unit. This is
not a personnel lift and never should
be used for hoisting or moving people.
Lifting Lowering

7. Using the Stabilizer Legs
The lift will arrive with the stabilizers legs
in the stowed position in the leg storage
pocket. To remove the legs, pull the
plunger ring located on the back of the
storage pocket while lifting up on the leg.
Remove the leg from the storage pocket
and place on the ground next to the corre-
sponding leg mounting socket.
Repeat for each leg.
Note: The two longer legs mount
towards the front of the lift.
Insert each leg into its’ respective mount-
ing socket making sure that the locking
plunger fully engages.
Using the leveling screws, level the lift un-
til the bulls eye bubble level shows that
the unit is level.
All four of the base casters should be off
of the ground when the lift is level.
WARNING
Never operate lift during
high wind conditions.
10
WARNING
Never operate lift if you
cannot level unit.
WARNING
Use of the stabilizer legs is required at
all times when raising loads.
WARNING
When erected on carpeting, place a
plate of solid material beneath each
stabilizer leg to ensure
proper support.

8. Mast Hold Down Strap
Securing the Carriage:
Lower the carriage all the way down. With
the forks in place, engage the Mast Hold
Down Strap onto one of the Safety Latch
Loops on the side of the Fork Assembly.
Pull on strap to tighten Hold Down. To re-
move Hold Down, press lever on cam
buckle and slacken Hold Down strap. Re-
move Hold Down from Safety Latch Loop
on side of fork.
Operating Your Lift:
When operating the lift, the Safety Latch
can be looped onto itself for out of the way
storage.
Resetting Safety Latch:
In the event that you
accidentally crank on the winch before dis-
engaging the Mast Hold Down, the spring
latch may deform. A spare spring latch is
located in the Operators Manual tube to
allow a quick return to operation.
11
WARNING
Transporting the lift without the mast
hold down strap engaged can cause
injury and/or damage to the lift.

9. Safety Brakes
The Safety Brake will automatically engage
when the unit is horizontal, preventing disas-
sembly of the mast sections. When this oc-
curs, the masts will extend, but not retract. A
special tool, which can be found in the Op-
erator’s Manual tube, is required to release
the brakes. If the tool is lost or damaged,
one can be made simply from a piece of 1/8
to 1/4 inch diameter steel rod 9 inches long
with both ends bent into an “L” shape 1-1/4
inches long.
To release the brake, lay the lift back onto
the winch wheels and place the tool into
brake access slot located on the left side of
the lift, and through the hole in the counter-
weight.
Pull the tool down and the brake will release.
It may be necessary to push the locked mast
(or Carriage) up slightly while pulling down
on the tool. Once the brake is released,
maintain pressure on the tool and slide the
mast sections apart.
Repeat this procedure for each mast section.
When the brake is engaged, it will be pos-
sible to see the Brake Cam acting on the
adjacent mast section. Once the brake is
released, it will rotate around into its nor-
mal position and will not be visible.
10. Boom
To use Boom, pull spring-loaded ring and
slide out the outer boom arm to desired
station. Release spring-loaded ring, mak-
ing sure that the plunger engages into the
locating hole. To attach applied adapters,
slide adapter in to the socket and secure
with the set screw for no movement.

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 20.
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.

17
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 on page 12, into
the access slot and through the hole in the coun-
terweight. 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.
