Quick Wrench
To attach or remove downhole tools, use quick wrench to join or break the joint.
Attach quick wrench in either the join or break position.
• Place jaws (1) on wrench flats on both sides of joint.
• Pin handles (3) to wrench jaws. Be sure handles are both up.
• Attach pivot nuts (4) to wrench handles so that screw drive handle (5) is over joint.
Moving tools will injure or kill. Shut off drill string power when anyone can
be struck by moving or thrown tools. Never use pipe wrenches on drill string.
IMPORTANT: Apply TJC to threads and hand-tighten joint before attaching quick wrench components to
tighten joint.
