4. Return the piston assembly (#41 to

CLEANING AND CHANGING
THE JAWS
1. Use the wrench (#51) to unscrew and remove the outer cylinder (#2) from
the housing (#15).
2. Unscrew and remove the jaw case (#3) using the wrench (#51).
IMPORTANT! Be careful when removing the jaw case (#3) as there is a jaw
pusher spring (#12) located behind the jaw case (#3) that could fly out.
3. Remove the jaws (#4 or 5) and jaw pusher (#11) from between the jaw
cases (#3).
4. Cleaning and changing the jaws:
a. Cleaning the jaws: Clean the jaws using a steel brush and mild
solvent. Before returning the jaw to the tool, apply a light coat of
machine oil to the jaws.
b. Replacing the jaws: If you are replacing the jaws (#4 or 5), the entire
assembly (#3, 4, 5, 11, 12) must be replaced at the same time. This is
a precaution in the event that other parts had become damaged when
the jaws were damaged.
5. Reinsert the jaws (#4, 5) and jaw pusher (#11) into the jaw case (#3).
IMPORTANT! The wedge on the jaw pusher’s (#11) head must line up
between the jaws (#4,5), pushing them slightly
apart, when reassembling the jaw case (#3).
6. Using the wrench gauge (#50), check the
distance from the head of the jaw case (#3)
to the mounting threads of the outer cylinder
(#2). With the gauge held at a small slant,
