•
It can be choosing pump freely.
•
The jaws with three can be adjusted form high to low point.
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 (8) will push
on the central shaft while 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.
Assembly
Note:For additional information regarding the parts and assembly, refer to the Assembly
Diagram near the end of this manual.
Assemble each of the three Jaws onto the Puller Sleeve (6) using Connector Plates (5) and Bolt Sets
(19) as shown. Insert the Handle (11) into the Pump Handle Socket (12).
Determine if the best grip on the part to be pulled is from the outside or the inside. The hooks on the
Jaws (1) face inward when gripping the part from the outside. They face outward when gripping the
part from the inside. 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.

•
Pump the Handle (11) up and down to force the Piston down, causing the Jaws to pull upward
•
Continue pumping the Handle, being sure the Jaws stay in place on the object and the object is
not being damaged.
