Install the Inlet Retainer Clip (26), Inlet Bushing Seal (28), Tilt Valve
Spring (29), Tilt Valve (30) Tilt Valve Seat (31) and Tilt Valve Seat

WARNING
The Tilt Valve Seat Retainer (33)must be properly installed in the
groove in the Inlet Bushing (24). To check for correct 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 entire 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.

NOTICE
When re-installing the Inlet Bushing Assembly, pull the Trigger (34)
outward and make sure that the Reverse Button (41) is depressed
before snapping the Inlet Bushing Assembly back into the Housing.

Install the Inlet Bushing Assembly by pushing it into the hole in the
Housing until you see and hear the tabs on Inlet Retainer Clip snap
into place through the slots in Housing handle.
NOTICE
The Reverse Button (left) (41) must be pushed in before the Trigger
can be installed. Otherwise, the Trigger will be damaged during
installation.
