TO PREVENT ACCIDENTAL INJURIES:
DESCRIPTION
The Powernailer®Model 445 FS Mallet Actuated
Pneumatic Stapler is the latest model designed to
bring Powernail quality to a pneumatic Stapler. For
those looking for the ease of use of a pneumatic tool,
the Powernailer Model 445FS—designed for use
with 1-1/2”, 1-3/4” and 2” PowerStaples®—provides
several distinct advantages. Like our Model 45 and
445, the Model 445FS can staple down 1/2”, 3/4” and
33/32” tongue and groove hardwood flooring through
the use of easy-to-change, no-mar adapter plates.
To use the Model 445FS, simply snug up the
flooring with the rubber mallet, pull the safety
trigger and tap the plunger with the rubber capped
mallet end and let the Stapler drive and set the
staple at the correct 45 degree angle.
For a superior pneumatic Stapler, look to the
company that has been the industry’s quality
leader for over 50 years, POWERNAIL®
COMPANY, INCORPORATED.
Always wear approved front and side EYE
PROTECTION when operating this Stapler. Others
in the work area should also wear front and side EYE
PROTECTION. Eye protection will help guard against
flying staples and debris, which could cause severe
eye injury.
EAR PROTECTION may be required to prevent
hearing damage when there are high noise levels in
the work area.
Always DISCONNECT THE AIR SUPPLY before
making any adjustments, repairing, clearing jams or
when the Stapler is not in use.
Never attach the female end of a quick disconnect to
the Stapler. This will trap air inside the Stapler and
permit it to be discharged. Only the unrestricted male
connection should be attached to the Stapler.
Use only regulated compressed air, do not use bottled
gases of any kind to power this Stapler. Normal air
pressure should not exceed 120 psi or damage to the
Stapler and seals may occur. Excess air pressure can
cause the Stapler to explode.
THE TRIGGER IS A SAFETY DEVICE and
should only be pulled when the Stapler is in
proper position on the work surface and before
the plunger is struck with the mallet. Do not tie or
tape down the safety trigger as the Stapler could
discharge if dropped on the plunger. The Stapler
will not fire unless the trigger is pulled before the
mallet blow.
Do not use the trigger safety as a lock up for
the plunger then rack the wood using the locked
up Stapler body. It will severely damage the
mechanism and the Stapler. Use the mallet to
rack the wood strip, not the Stapler.
DO NOT USE THE METAL END OF THE
MALLET TO STRIKE THE PLUNGER, use the
rubber capped end only.
Never place any part of the body in the discharge
path of the Stapler when air is connected to the
Stapler. Always make sure Stapler is empty
of staples before connecting air hose so as to
prevent any accidental discharge from occurring.
Never leave the Stapler unattended while it is
connected to an air supply.

WARNING Whenever air is connected
to the Stapler, keep body
parts away from the staple discharge path.
Disconnect the air line before making adjustments
or repairs on the Stapler. Only connect air to an
unloaded Stapler so as to prevent accidental
discharge.
Consult the drawing for the appropriate adapter
pad to use with the thickness of flooring you are
installing.
Rack the flooring into place with the rubber end of
the mallet supplied with the Stapler
Place the Stapler Adapter Foot on the tongued
edge of the flooring strip to be stapled. Be sure
the Adapter Foot is pressed tightly against the
edge of the flooring strip above the tongue.
Be sure flooring strips are racked tightly. Pull the
Safety Trigger and tap the Stapler Plunger Rubber
Cap with the rubber capped end of the mallet to
discharge the Stapler.
WARNING It is not necessary to hit the
Stapler hard to activate it. Never hit the Stapler
with excessive force or with the metal end of the
mallet, this will damage the Stapler.
Never use the Safety Trigger interlock to lock up
the plunger and rack the wood with blows to the
Stapler body. This will severely damage the safety
mechanism and Stapler. This abuse and damage
is not covered by the warranty.
Before each use check all screws to be sure they
are tight. Shock and vibration can loosen screws.
Do not over tighten any screw.
AIR SUPPLY:
The air must be clean and dry. Dirty and/or wet
air will damage the Stapler. A combination filter-
regulator-lubricator is required for proper Stapler
performance and should be placed close to the
Stapler per manufacturers’ recommendations.
Drywall Dust:
• Using Pneumatic PowerStapler in drywall
dust conditions will dramatically decrease the
life of the Stapler.
• Drywall dust is abrasive, when cycled through
the Stapler it will cause excessive wear.
Fill the lubricator with a high-quality Air Tool
Oil. Adjust the lubricator to the manufacturers’
recommendations. Do not over oil the Stapler, as
excess oil will be discharged with the spent air and
could stain the wood flooring, walls or furnishings.
We will not be responsible for oil stains.
WARNING Detergent oil is
not recommended and may damage the
seals. Consult the filter regulator lubricator
manufacturer’s recommendations for proper
operation, settings and unit maintenance.
The air source must continuously deliver 100
to 120 psi and 3-1/2 cubic feet of air per minute
to operate the Stapler Connect a 1/4” minimum
internal diameter and clean air hose to the Stapler.
Be sure the air regulator is set at 90 psi. If the
staple is not countersunk below the surface of the
wood, turn up the air pressure, but not over 120
psi.
Check for air supply leaks that waste air and
starve the Stapler of air thereby reducing its
performance. There should be no orifice smaller
than 1/4” in the air path between the Regulator
and the Stapler.
LUBRICATION:
If you do not use an in line lubricator, you must
lubricate the Stapler manually. The frequency of
lubrication is dependent upon the duty cycle of the
Stapler. Continuous duty requires more frequent
oiling than intermittent duty.
At least every eight (8) hours place two to four
drops of Air Tool Oil, supplied with your Stapler,
into the disconnected air line male connector
attached to the Stapler.
WARNING Do not over lubricate the
Stapler, excess oil mist or drops will be vented
with spent air when over lubricated. Excess oil
could stain the wood flooring, walls or furnishings.
Dry fire the Stapler, without nails, to purge excess
oil, before you begin to staple down flooring.
We will not be responsible for oil stains. Before
storing the Stapler, lubricate and cycle the Stapler
in insure internal parts are oil protected from
corrosion.
