These general instructions deal with
the normal installation, operation and
maintenance situations encountered
with the Grip Puller described herein.
The instructions should not be
interpreted to anticipate every possible
contingency or to anticipate the final
system or configuration that uses
these Grip Pullers.
These instructions include information
for a variety of hand chain hoists.
Therefore, all instructions and
information may not apply to one
specific Grip Puller. Disregard those
portions of the instructions that do
not apply.
1. Read and understand owner’s manual before
operating grip puller. Familiarize yourself with the
content of the warning label on your puller.
2. Do not exceed rated capacity.
3. Supporting structure used with this device must
provide adequate support to handle all puller
operations plus the weight of the puller and attached
equipment. If in doubt, consult a registered structural
engineer.
4. Never use handle extensions (cheaters).
5. Do not use with twisted, kinked, frayed or otherwise
damaged wire rope.
6. Do not use if grip puller is damaged or malfunctioning.
7. Do not lift people or loads over people. Always keep
people clear from load path.
8. When using grip puller to lift vertically, make sure hook
is centered under the puller.
9. Do not use as a tow line.
10. Do not use with a hook that is open or twisted, or
without safety latch.
11. Never run wire rope over a sharp edge.
12. Never leave a suspended load unattended.
13. Do not swing a suspended load.
14. Always inspect the puller before each use. Replace if

15. Always use gloves when handling wire rope. Do not
wear loose clothing which can become entangled in
moving parts.
16. Do not use this grip puller in an explosive
environment.
17. Give your work undivided attention. Looking around,
carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
18. Do not operate this tool while tired or under the

UNPACKING
Open carton and check for shipping damage. Report any
damage immediately to your distributor and shipping agent.
Do not discard any shipping material until the Grip Puller is
assembled and operating properly.
Compare the contents of your container with the following
parts list to make sure all parts are intact. Missing parts, if any,
should be reported to your distributor. Read the instruction
manual thoroughly for assembly, maintenance and safety
instructions.
ASSEMBLY AND SETUP
Pre-Lubrication
Before proceeding with assembly, lubricate the puller as
follows: Apply a lubricating oil to the puller mechanisms while
continuously operating the reverse lever. This will help spread
the oil to the internal parts. Use special care to oil pawls and
links well. A wear resistant oil is recommended.
CAUTION: Without proper lubrication, the pawls will fail to
engage the wire rope, and the wire rope will not move.

INSERTING WIRE ROPE
1. Release the clamp by pushing the clamp lever securely into
the notch on the puller body.
2. Insert the end of the wire rope into the rope inlet at the
rear of the puller. Feed the wire rope through until it emerges
at the other end.
3. Pull the wire rope through by hand to take up the slack and
make sure the exit point is not obstructed.
4. While keeping the wire rope taut, push down on the clamp
lever and allow it to spring back to its natural position.
This will engage the wire rope within the puller.
5. Mount the telescopic handle to either the forward or reverse
lever, according to the action desired. Rotate the handle
until it is secure on the lever.
6. The puller is now ready to operate.
Insert Wire Rope
Figure 2.
OPERATION
The grip puller uses standard ASA wire rope and may be used
in any position to lift, pull, lower or stretch heavy loads. Before
attempting operation of this product, you should become
thoroughly familiar with the warnings on page 3.
To operate the grip puller:
1. Place load cable(s) in the middle of the hook and inside the
safety latch. DO NOT attach any cables outside the safety latch
on either the puller hook or the wire rope hook.
2. Lay out the wire rope correctly without twisting. Twisting the
wire rope reduces its strength. See Figure 5.
3. To send the wire rope forward, set the telescopic handle on the
forward lever and move it back and forth.
4. To send the wire rope backward, set the telescopic handle on
the reverse lever and move it back and forth.
IMPORTANT: A shear pin is installed in the forward lever. If the
load being handled is too excessive for the puller’s capacity,
the shear pin is designed to break. If this occurs, decrease the load or use other equipment of higher pulling capacity.
The broken shear pin is easily replaced using one of the spare
shear pins which are found within the hand grip of the pullers.

Safety Latch
Correct
Before storing the grip puller:
1. After use, remove the wire rope from the main body by setting
the clamp lever into the notch (disengage clamp), then pulling
the wire rope from the inlet side at the rear of the puller.
2. After the wire rope is removed, push the clamp lever out of the
notch and let it snap back to its original position. If the clamp
lever is kept in the notch for an extended time period, its spring
may become stretched.
3. Wipe off any sand or water from the puller body, including
internal mechanisms, and the wire rope, then apply oil
liberally to both.
4. Store the grip puller away from rain, dew, high humidity areas
or around acidic chemicals, which will promote rusting.

MAINTENANCE
Make frequent and careful inspections of the puller. Make
sure puller and wire rope are sufficiently oiled, and that
they are free of any sand, dirt, dust or other obstruction or
abnormality.
Make sure hooks are not deformed and that the puller body
has not been warped or damaged.
Use care to prevent the wire rope from kinking. If the rope
is left shaped like a basket or is kinked many turns at a
single point, its strength is greatly diminished and may
result in failure.
Replace the wire rope immediately if:
• The thickness of the rope becomes less than
half of the original value due to abrasion.
• The rope exhibits basket-like shapes, kinks,
or any abnormal deformation.
• The rope is given an exceptionally heavy shock during
operation; this can fatigue the rope even if the load is
within puller capacity.
• The entire rope is napped due to many small cuts.
• The eye section (thimble) of the wire rope becomes
elliptical in shape.
• The clamp is deformed.
TROUBLESHOOTING
Trouble Probable Cause Remedy
Insufficient lubrication. Oil the puller and wire rope.
Wire rope will not move in
either direction.
Puller is dirty. Disassemble and clean out dust, dirt or other
foreign matter. Oil the puller after reassembly.
Wire rope will not advance
during normal operation, or
advances with great difficulty.
Clamp lever will not engage
the wire rope properly.
Clamp lever is not in proper
position.
Clamp lever is not in proper
position.
Pawls are not lubricated. Oil the pawl linkages properly;
Load is beyond puller capacity. Decrease load.
There is an obstruction within the
wire rope’s path.
The reverse lever is engaging the
wire rope.
Spring on clamp lever has
become stretched.
Release clamp lever from notch,
and allow it to return to engaged position.
Release clamp lever from notch,
and allow it to return to engaged position.
the pawls must engage the wire rope.
Remove the wire rope; clean and oil the puller
and the wire rope.
Check the position of the reverse lever.
Correct as needed.
Replace spring.
