Powernail Parts Store at http://www.powernail.com

Always wear approved front and side EYE
PROTECTION when operating this Nailer.
Others in the work area should also wear front
and side EYE PROTECTION. Eye protection will
help guard against ying nails 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 Nailer is not in use.
Never attach the female end of a quick
disconnect to the Nailer. This will trap air inside
the Nailer and permit it to be discharged. Only
the unrestricted male connection should be
attached to the Nailer.
Use only regulated compressed air, do not use
bottled gases of any kind to power this Nailer.
Normal air pressure should not exceed 120 psi
or damage to the Nailer and seals may occur.
Excess air pressure can cause the Nailer to
explode.
THE TRIGGER IS A SAFETY DEVICE and should
only be pulled when the Nailer 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 Nailer could discharge
if dropped on the plunger. The Nailer will not re
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
Nailer body. It will severely damage the mechanism
and the Nailer. Use the mallet to rack the wood
strip, not the Nailer.
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 Nailer when air is connected to the
Nailer. Always make sure Nailer is empty of cleats
before connecting air hose so as to prevent any
accidental discharge from occurring.
Never leave the Nailer unattended while it is
connected to an air supply.
The Powernailer®Model 445 Mallet Actuated
Pneumatic Nailer is the latest model designed
to bring Powernail quality to a pneumatic Nailer.
For those looking for the ease of use of a
pneumatic tool, the Powernailer Model 445—
designed for use with 1-1/2”, 1-3/4” and 2”
Powercleats®nails—provides several distinct
advantages. Like our Model 45, the Model 445
can nail down 1/2”, 3/4” and 33/32” tongue and
groove hardwood ooring through the use of
easy-to-change, no-mar adapter plates.

TO PREVENT ACCIDENTAL INJURIES:
DESCRIPTION
To use the Model 445, simply snug up the ooring with
the rubber mallet, pull the safety trigger and tap the
plunger with the rubber capped mallet end and let the
Nailer drive and set the nail at the correct 45 degree
angle.
For a superior pneumatic Nailer, look to the company
that has been the industry’s quality leader for over 50
years, POWERNAIL®COMPANY, INCORPORATED.

WARNING Whenever air is connected to
the Nailer, keep body parts
away from the nail discharge path. Disconnect the
air line before making adjustments or repairs on the
Nailer. Only connect air to an unloaded Nailer so
as to prevent accidental discharge.
Consult the drawing for the appropriate adapter
pad to use with the thickness of ooring you are
installing.
Rack the ooring into place with the rubber end of
the mallet supplied with the Nailer
Place the Nailer Adapter Foot on the tongued
edge of the ooring strip to be nailed. Be sure the
Adapter Foot is pressed tightly against the edge of
the ooring strip above the tongue.
Be sure ooring strips are racked tightly. Pull the
Safety Trigger and tap the Nailer Plunger Rubber
Cap with the rubber capped end of the mallet to
discharge the Nailer.
WARNING It is not necessary to hit the
Nailer hard to activate it. Never hit the Nailer with
excessive force or with the metal end of the mallet,
this will damage the Nailer.
Never use the Safety Trigger interlock to lock up
the plunger and rack the wood with blows to the
Nailer body. This will severely damage the safety
mechanism and Nailer. 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 Nailer. A combination lter-
regulator-lubricator is required for proper Nailer
performance and should be placed close to the
Nailer per manufacturers’ recommendations.
Drywall Dust:
• Using Pneumatic Powernailers in drywall dust
conditions will dramatically decrease the life of
the Nailer.
• Drywall dust is abrasive, when cycled through
the Nailer 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 Nailer, as
excess oil will be discharged with the spent air and
could stain the wood ooring, walls or furnishings.
We will not be responsible for oil stains.
WARNING Detergent oil is not
recommended and may damage the seals. Consult
the lter 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 Nailer Connect a 1/4” minimum internal diameter
and clean air hose to the Nailer. Be sure the air
regulator is set at 90 psi. If the nail 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 Nailer of air thereby reducing its performance.
There should be no orice smaller than 1/4” in the air
path between the Regulator and the Nailer.
LUBRICATION:
If you do not use an in line lubricator, you must
lubricate the Nailer manually. The frequency of
lubrication is dependent upon the duty cycle of the
Nailer. 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 Nailer, into the
disconnected air line male connector attached to the
Nailer.
WARNING Do not over lubricate the Nailer,
excess oil mist or drops will be vented with spent air
when over lubricated. Excess oil could stain the wood
ooring, walls or furnishings. Dry re the Nailer,
without nails, to purge excess oil, before you begin to
nail down ooring.
We will not be responsible for oil stains. Before
storing the Nailer, lubricate and cycle the Nailer in
insure internal parts are oil protected from corrosion.
