Unpacking, Mounting and Assembly
Operation
1. With the help of an assistant, carefully
uncrate the planishing hammer. A tab is
welded to the top t ube if you choose t o use
a hoist to set up the machine.
2. Determine the most suitable location for
your planishing hammer based on the
planned usage of the machine. Larger
workpieces require a larger space around
the planishing hammer.
3. Mount an y loose item s to the fr ame, suc h as
the die trays, using the pho to on page 7 and
the breakdown on page 10 as guides.
4. Lower the foot pads to contact the floor, using
the handwhee l.
5. Secure the planishing hammer to the floor
using fastener s (not inc luded) appr opriate f or
the floor type. These are inserted through the
holes on the frame’s back leg.
Referring to Figure 2:
6. Attach the pneumatic hammer to the frame
with the upper clamp (has rounded notch)
and lower clamp. Secure the clamps with
four M6x25 socket head cap screws and M6
lock washers.
Keep hands clear of hammer
and anvil area at all times! Failure to comply
may cause serious injury!
Referring to Figure 3:
1. Connect the air compressor to the quick
connector.
2. Set the d es ired air pres s ure bet wee n 90- 1 20
PSI using the pressure dial on the
filter/regulator (clockwise to increase). Lock
the setting by pushing down the pressure
dial. Pull up on the dial to r eadjust a s etting.
Note: A lower air pressure will provide a
softer hammer blow. Do not exceed 120 psi air pressure.
3. Adjust the oil flo w using the dial at th e top of
the lubricator. A setting of 2 drips per m inute
is sufficient for regular operation.
Referring to Figure 3:
7. Check the oil leve l in the lubricator. If the oil
level is low, refill. Refer to Maintenance
section for instructions.
8. Install a male 1/4" quick connector fitting
onto the air inlet of the planishing hammer.
Figure 3
Referring to Figure 4:
4. Adjust the anvil height with the handwheel,
and secure the anvil in position by snug ging
the lockcollar against the frame.
5. The lock handle can be inserted into an y of
the threaded holes in the collar, and
tightened using a wrench on the flats.

To remove the entire driver from the hammer
barrel, push the tab on the air ham mer housing
and pull down on the driver. To reinstall the
hammer drive, orient the notch toward the
general direction of the tab, and push driver
upward while still pushing back on the tab.
When the driver is properl y inserted, the tab will
snap back into place.
Make sure driver and di e s are
properly inserted before operating machine.
Figure 4
6. Plug the planishing hamm er into the power
supply.
7. With the workpiece between the hammer
and anvil (Figure 5), pres s the foot switc h to
begin planishing.
Note: Planishing blows-per-minute can be adjusted
by turning adjustment knob ( see Fig ure 2 ).

Maintenance
Figure 5
Changing Dies
Referring to Figure 6:
The PH-24T is shipped with one crowned anvil
(or lower) die, and one flat hammer (or upper)
die, which is already installed in the driver.
To remove an anvil die, loosen the set screw
and pull straight up on the anvil die. Install a new
anvil die and tighten set screw. The anvil post
accepts dies with a standard 0.79” insert end.
To remove a hammer die from the driver, use a
tool to separate them . W hen the die is rem oved,
check the condition of the o-ring inside the
driver. To reinstall a hammer die, insert it into
the driver and raise the anvil post up until it
contacts and pushes the die in.
Check the following before every use:
Oil level in the lubricator; refill as needed
with ISO 32/SAE 10W non-detergent, nonadditive oil. Remove oil plug with a
screwdriver to fill.
All mounting and component hardware and
fasteners; adjust/tighten as necessary.
All air connections; replace leaking or
defective connections.
Worn or shorted wiring; replace as
necessary.
Periodically check the filter/regulator bowl for
fluids or sediment ac cumulation, and empty it if
needed. To remove a bowl, shut off air supply
and bleed excess air; t hen press the tab, rotate
bowl to the left, and pull down. Reverse
procedure to reinstall bowl. Make sure bowl is
locked in position before applying air to the
system!
