Installation
Mounting “C” Frame
1.
Select a workbench in the shop area able to support the weight of the Planishing
Hammer, the metal being worked on, and the vibration of the planishing process.
2.
Mount the “C” Frame (1) to the workbench using hardware (not supplied).
The “C” Frame should be positioned so that the mounted Air Hammer (10) is
extended slightly over the edge of the workbench. This will accommodate various
shapes of metals being planished. Hardware should consist of nuts, bolts, flat
washers, and lock washers.
Note: There is an entry hole on the side of “C” Frame (1) where sand can be inserted to
reduce noise and vibration.
Air Connection
1.
Attach a Union fitting (not supplied) into the Switch Assembly Inlet (13) fitting.
A Union fitting is necessary before a connection can be made to an Air Compressor.
2.
For easy connection or removal, attach an Air Coupler (not supplied) to the Union
fitting, if quick-coupling is desired.
3.
Retighten all couplings and fittings.
4.
Attach the Air Hose (not supplied) from the Air Compressor (not supplied) to the

Oiler and Filter Connection
Dirt, water, and the lack of pneumatic tool oil are major causes for tool wear. Install an
optional oiler-filter (not supplied), as illustrated below for better performance.

illustrated below. Use pipe thread seal or Teflon tape on all threaded connections.
The filter and oiler (not supplied) are recommended but not mandatory for operation.
If the filter and oiler are not used, connect the air hose directly to the 1/4 inch, 18 NPT
connector located at the Air Switch Assembly Inlet (13) fitting. Also, a few drops of
pneumatic tool oil must be added through the air line before each use.
