Assembly and Set-Up
Pre-Lubrication
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 internal 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 puller. 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 rear of the puller. Feed the
wire rope through until it emerges at the
other end.
