WARNING:
The Tilt Valve Seat Retainer
(32) must be properly installed
in the groove in the Inlet Bush-
ing (23). Failure to do so could
result in injury. To check for cor-
rect installation of the Retainer,
insert a pin into one of the holes
in the Retainer and rotate the
Retainer. A correctly installed
Retainer will rotate freely but
with some resistance in the
groove of the Inlet Bushing. An
incorrectly installed Retainer will
pop out of the Inlet Bushing
when the Retainer is rotated.
WARNING:
Do not use compressed air to
check installation of the Tilt
Valve Seat Retainer or Inlet
Bushing Screen unless the en-
tire Inlet Bushing Assembly is
installed in the tool with the
Hammer Case installed and
properly secured to the Motor
Housing. Failure to do so could
result in injury.

tainer.
