refer to the Assembly Diagram near the end of this manual.
Assembly
1.
Thread the Puller Sleeve (6) onto
the Puller Unit about halfway up the
threaded section of the Puller Unit.
2.
Determine if the best grip on the part
to be pulled is from the outside or the

inward when gripping the part from
the outside. They face outward when
gripping the part from the inside.
3.
The jaws have four different settings
(twoholes
and
then
ip
over
the
Jaws
for
the other two settings). Each can be for both
inside and outside pulling. Determine whether
to use the upper or lower holes in the Jaws
and which way the jaws should be turned.
WARNING!
Turn all the jaws the same
way to ensure even pulling.
4.
Assemble each of the three Jaws
onto the Puller Sleeve (6) using
two Connector
Plates

Functions
The tool is designed to pull items such as
bearings, pulleys, and chucks from shafts.
The
Jaws (1) can grip the object from the
inside or outside, whichever offers a better grip.
The
Piston

the Jaws pull away. This will remove the item from
the shaft by pulling it straight out evenly, without
hammering or binding from pulling at an angle.
