ePlacement
1. Using Dial Calipers or an interchangeable Anvil
Micrometer, measure the Puller to determine if it is
worn out or new. (The Puller does not have to be
removed from the tool to be measured.)
2. Remove the setscrews from the anvil holder, and
unscrew the anvil holder from the tool.
3. Unscrew the setscrews from the Puller, then
unscrew the Puller from the piston.
4. After the Puller has been unscrewed from the
Piston,
remove and clean all its components
.
NOTE
:
To add life to the Puller, always clean
components upon changing or checking Puller.
a) Insert the spring into the piston.
b) Insert the actuator rod into the piston.
c) Insert the rod guide into the piston.
d) Screw the puller onto the piston.
5. Reinstall the components before screwing a NEW
Puller onto the Piston.
6. Apply Loctite Anti-Seize or
an equivalent lubricant to
the Puller to keep it from
wearing against the Anvil
during the first several
drives.
7. a) Bottom the anvil holder
on the piston.
b) Back off the anvil holder until a groove is visible
through the setscrew hole.
c) Install the setscrew.
8. Check the Limit Switch setting using the Controller
or a Light Box and the depth micrometers. Adjust
within the specification of .430”–.435”. See
