2. Install the Washer (1A), Inlet Retainer Clip (21), Inlet
Bushing Seal (1B), Tilt Valve Spring (1C), Tilt Valve
(1D) Tilt Valve Seat (1E) and Tilt Valve Seat Support
(1F).
The Tilt Valve Seat Retainer (1G) must be properly
installed in the groove in the Inlet Bushing (20). 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.
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.
Install the Tilt Valve Seat Retainer.
When re–installing the Inlet Bushing Assembly
(20), pull the Trigger (28) outward and make sure
that the Reverse Button (4B) is depressed before
snapping the Inlet Bushing Assembly back into the
Housing.
3. 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.
The Reverse Button (left) (4B) must be pushed in
before the Trigger can be installed. Otherwise, the
Trigger will be damaged during installation.
