1. Read and understand the entire owner’s manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with
all of these warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. This planishing hammer is designed and intended for use by properly trained and experienced
personnel only. If you are not familiar with the proper and safe operation of a planishing hammer, do
not use until proper training and knowledge have been obtained.
5. Do not use this planishing hammer for other than its intended use. If used for other purposes, Walter
Meier (Manufacturing) Inc., disclaims any real or implied warranty and holds itself harmless from any
injury that may result from that use.
6. Always wear approved safety glasses/face shields while using this planishing hammer. Everyday
eyeglasses only have impact resistant lenses; they are not safety glasses.
7. Before operating this planishing hammer, remove tie, rings, watches and other jewelry, and roll
sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or
anti-skid floor strips are recommended.
8. Wear ear protectors (plugs or muffs) during extended periods of operation.
9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
•
•
•
Lead from lead based paint.
Crystalline silica from bricks, cement and other masonry products.
Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area and work with approved safety
equipment, such as face or dust masks that are specifically designed to filter out microscopic
particles.
10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
11. Make certain the machine is properly grounded.
12. Make all machine adjustments or maintenance with the machine unplugged from the power source.
13. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting
wrenches are removed from the machine before turning it on. .
14. Check damaged parts. Before further use of the machine, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting
and any other conditions that may affect its operation. A guard or other part that is damaged should
be properly repaired or replaced.
15. Provide for adequate space surrounding work area and non-glare, overhead lighting.
16. Keep the floor around the machine clean and free of scrap material, oil and grease.
17. Don't use in dangerous environment. Don't use power tools in damp or wet locations, or expose them
to rain. Keep work area well lighted.
18. Keep visitors a safe distance from the work area. Keep children away.
19. Make your workshop child proof with padlocks, master switches or by removing starter keys.

20. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
21. Do not overreach. Keep proper footing and balance at all times.
22. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for
which it was not designed. The right tool will do the job better and more safely.
23. Use recommended accessories; improper accessories may be hazardous.
24. Maintain tools with care. Follow instructions for lubricating and changing accessories.
25. Disconnect tools before servicing or changing accessories.
26. Use leather gloves when handling sheet metal.
27. Keep hands, fingers and arms away from the hammer and anvil during operation.
28. Do not exceed the maximum rated air pressure to the regulator.
29. Disconnect tool from air supply when not in use.
30. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do
not use your hands.
31. Do not stand on the machine. Serious injury could occur if the machine tips over.
32. Never leave the machine running unattended. Turn the power off and do not leave the machine until it
comes to a complete stop.
33. Remove loose items and unnecessary work pieces from the area before starting the machine.

Unpacking, Mounting and Assembly
Operation
1. With the help of an assistant, carefully
uncrate the planishing hammer. A tab is
welded to the top tube if you choose to use
a hoist to set up the machine.
Keep hands clear of hammer
and anvil area at all times! Failure to comply
may cause serious injury!
Referring to Figure 3:
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.
1. Connect the air compressor to the quick
connector.
2. Set the desired air pressure between 90-120
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 readjust a setting.
Note: A lower air pressure will provide a
softer hammer blow. Do not exceed 120
psi air pressure.
3. Mount any loose items to the frame, such as
the die trays, using the photo on page 7 and
the breakdown on page 10 as guides.
4. Lower the foot pads to contact the floor, using
the handwheel.
5. Secure the planishing hammer to the floor
using fasteners (not included) appropriate for
the floor type. These are inserted through the
holes on the frame’s back leg.
3. Adjust the oil flow using the dial at the top of
the lubricator. A setting of 2 drips per minute
is sufficient for regular operation.
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.
Referring to Figure 3:
7. Check the oil level 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 snugging
the lock collar against the frame.
5. The lock handle can be inserted into any 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 hammer 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 properly inserted, the tab will
snap back into place.
Make sure driver and dies are
properly inserted before operating machine.
Figure 4
6. Plug the planishing hammer into the power
supply.
7. With the workpiece between the hammer
and anvil (Figure 5), press the foot switch to
begin planishing.
Note: Planishing blows-per-minute can be adjusted
by turning adjustment knob (see Figure 2).
Figure 6
Maintenance
Check the following before every use:
ˆ Oil level in the lubricator; refill as needed
Figure 5
with ISO 32/SAE 10W non-detergent, non-
additive oil. Remove oil plug with
screwdriver to fill.
a
Changing Dies
Referring to Figure 6:
ˆ All mounting and component hardware and
fasteners; adjust/tighten as necessary.
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.
ˆ All air connections; replace leaking or
defective connections.
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.
ˆ Worn or shorted wiring; replace as
necessary.
Periodically check the filter/regulator bowl for
fluids or sediment accumulation, and empty it if
needed. To remove a bowl, shut off air supply
and bleed excess air; then 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!
To remove a hammer die from the driver, use a
tool to separate them. When the die is removed,
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.
