General Instructions
1. Whenever grasping a tool or
part in a vise, always use leath-
er-covered vise jaws to protect
the surface of the part and help
prevent distortion. This is partic-
ularly true of threaded members
and housings.
NOTICE:
Always use leather-
covered vise jaws when clamp-
ing the handle in a vise. Leather
will conform to the shape of the
handle and allow the tool to be
held securely. To prevent dam-
age to the exhaust diffuser, nev-
er clamp only the bottom of the
handle.
2. Always clean every part and
wipe every part with a thin film
of oil before installation.
NOTICE:
Do not remove
grease from the impact mecha-
nism or Hammer Case (16). If
the impact mechanism has not
been disassembled, inject
Craftsman No. 18830 Grease
through the Hammer Case
Grease Fitting (18). When dis-
assembling and assembling the
impact mechanism, remove all
grease from the impact mecha-
nism and Hammer Case and lu-
bricate the impact mechanism
and Hammer Case Bushing
(17) with Craftsman No. 18830
Grease.
3. Apply a film of o-ring lubricant to
all O-rings before final assem-
bly.
