Unpacking
Open shipping container 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 conta iner with the
following parts list to make sure all parts are
intact. Missing parts , if any, should be reporte d
to your distributor. Read the instruction manual
thoroughly for assembly, maintenance and
safety instructions.
Before proceeding with assembly, lubricate the
puller as follows: Apply oil to the puller
mechanisms while continuously operating the
reverse lever (see Figure 1). This will help
spread oil to interna l parts. Use special care to
oil pawls and links well. A wear-resistant oil is
recommended.
Without proper lubrication,
the pawls will fail to engage the wire rope,
and the wire rope will not move.
Inserting Wire Rope
1. Attach the eye of the swivel hook to the
fastening bolt on the pul ler. Be sure to install
the cotter pin through the fastening bolt.
Attach the hook to a suitable anchorage
point, as shown in Figure 2.
2. Release the clamp by pushing the clamp
lever securely into the notch on the puller
body.
3. Insert the end of the wire rope (the end is
welded to provide easy entrance) into the
rope inlet at the re ar of the puller. Feed the
wire rope through until it emerges at the
other end.
Figure 2

4. Pull the wire rope through by hand to take
up the slack and make sure that the exit
point is not obstructed.
5. While keeping the wire rop e taut, p us h do wn
on the clamp lever and allow it to spring
back to its natura l position. This will eng age
the wire rope within the puller.
6. 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.
7. The puller is now ready to operate.
Operation
The grip puller uses standard ASA wire rope
and may be used in any position to lift, pull,
lower or stretch hea vy 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 s afety latch. DO NOT attach
any cables outside the safety latch on either
the puller hook or the wire rope hook. See
Figure 5.
Figure 3
2. Lay out the wire rope correctly without
twisting. Twisting the wire rope reduces its
strength. See Figure 6.
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 she ar pin (#25 in the p arts list)
is installed in the for ward lever. If the load bein g
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 repl aced usin g one of
the spare shear pins whic h are found within the
hand grip of the 1-1/2 and 3-ton pullers (see
Figure 1) and in the telesc opic han dl e of the 3/4ton puller.

Before storing the grip puller:
5. 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.
6. After the wire rope is removed, push the
clamp lever out of the notc h 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.
7. Wipe off any sand or water from the puller
body, including internal mechanisms, and
the wire rope, then apply oil liberally to both.
8. Store the grip puller away from rain, dew,
high humidity areas or around acidic
chemicals, which will promote rusting.
Make sure hooks are not def ormed 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 shape d like a bask et or is kink ed
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 bask et-like shapes, kinks,
or any abnormal deformation.
• The rope is given an exceptionally heavy
shock during operat ion; this can fatigue the
rope even if the load is within puller
capacity.
•The entire rope is napped due to many small
cuts.
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.
• 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.
Wire rope will not
advance during
normal operation, or
advances with great
difficulty.
Puller is dirty.
Clamp lever is not in proper position.
Clamp lever is not in proper position.
Pawls are not lubricated.
Load is beyond puller capacity. Decrease load.
There is an obstruction within the wire
rope’s path.
Disassemble and clean out dust, dirt
or other foreign matter. Oil the puller
after reassembly.
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.
Oil the pawl linkages properly; the
pawls must engage the wire rope.
Remove the wire rope; clean and oil
the puller and the wire rope.
The reverse lever is engaging the
wire rope.
Clamp lever will not
engage the wire rope
properly.
Spring on clamp lever has become
stretched.
Check the position of the reverse
lever. Correct as needed.
Replace spring.
