Setup (cont'd)
Pipe Adapter (cont'd)
Install the vise chains properly.
• Follow the vise chain tightening instructions care-
fully. Improperly tightened chains can allow the
puller to slide or break loose and strike nearby
personnel.
• Do not allow the vise chains to bind at the corners
when mounting the puller to a square or rectangular
support. The vise chain must be uniformly tight at
all points.
Failure to observe these warnings can result in severe
injury or death.
3. On each vise chain unit:
a. Rotate the vise chain handle counterclockwise to
expose most of the threads. Leave only three or
four threads engaged in the handle.
b. Insert the chain into the slot in the frame. Wrap
the chain around the conduit, pipe sheave adapt-
er, or structural element.
c. Set the positioner against the positioning blocks
that protrude from the frame.
d. Pull the vise chain tight and insert the chain pins
into the chain pockets, or recesses.
e. Turn the handle clockwise to slightly tighten the
chain.

to tighten the chain. Do not use tools, extensions or

and hitch pin clip.

structures, install a 12" sheave (Greenlee 00843).
