Jaw grip force adjustment system for offset and 90 degree pulling heads

A method of adjusting a jaw gripping force of a pulling head, said method comprising:

• a) providing a power tool having a piston and a head;
• b) providing a pulling head having a frame having first and second ends and a jaw gripping assembly which is generally positioned within said frame;
• said first end of said frame being configured to receive a stem of a fastener therein, said piston of said power tool being operatively associated with said jaw gripping assembly of said pulling head;
• and
• c) providing an adjustment assembly which is operatively associated with at least one of said frame and said jaw gripping assembly;
• d) manipulating said adjustment assembly in a first manner to move said jaw gripping assembly closer to said first end of said frame in order to minimize an amount of jaw grip force generated by said jaw gripping assembly;
• and
• e) manipulating said adjustment assembly in a second manner to move said jaw gripping assembly distal to said first end of said frame in order to maximize an amount of jaw grip force generated by said jaw gripping assembly.
