Maintenance
before Every Use
•
If lubricating manually, place 5 drops of pneu-
matic tool oil in the foot switch air fitting and
the hammer assembly air fitting.
• If you are using an in-line lubricator, check
the oil level; refill as needed with pneumatic
tool oil.
• Check all mounting and component hardware
and fasteners; adjust/tighten as necessary.
• Check all air connections; replace leaking or
defective connections.
Operation
The basic operation of a planishing hammer con-
sists of inserting a piece of sheet metal between
the hammer and die, then actuating the planishing
hammer while moving the sheet metal around to
shape it.
There are three main variables that can be
adjusted to alter the results of your work:
• Die Radius: Controls the curve of the shaped
workpiece. Change this by installing dies with
different radii.
• Air Supply PSI: Controls the force of each
blow of the hammer. Change this by adjust-
ing the air pressure between 50-100 PSI.
• Hammer Speed: Controls how fast and hard
the hammer strikes the die while the foot
switch is pressed. This is measured in BPM's
(beats per minute). Change this by adjusting
the speed adjustment knob on the hammer
assembly.

4. Connect the air pressure and adjust the air
supply PSI between 50-100, using your air
regulator.
5. Adjust the hammer speed, using the speed
adjustment knob on the hammer assembly.
6. Insert the workpiece between the hammer
and die, press down on the foot switch, and
move the workpiece around to shape it.
7. When a shaping task is complete, remove
your foot from the pedal to stop the planishing
hammer.
8. At the end of the day, or before leaving the
planishing hammer unattended, disconnect
the air supply from the foot switch and press
the foot switch to release any remaining air
pressure.
To perform a basic operation with the planish-
ing hammer:
1. DISCONNECT THE AIR PRESSURE!
2. Insert the desired die size into the housing.
3. Adjust the height of the die, using the die
elevation lever ( Figure 13) to accommodate
the thickness or gauge of your workpiece
