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.

NAILER DISASSEMBLY:
TO REPLACE RUBBER BUMPER (#20 or #65):

1. Disconnect the air supply

2. Remove the four (4) cap screws holding the
Adapter Foot, Foot and Nail Channel assembly to

the main Body (see illustration).

3. Pull the Rubber Bumper out of the cylinder bore.
Replace the old Bumper if it shows signs of wear or

it is split.

4. Reverse these steps to reassemble the Nailer. Be
sure to align the Driving Blade with the slot in the

Nail Channel Assembly while you reassemble the
Nailer.

NEVER FIRE THE NAILER WITHOUT THE

RUBBER BUMPER INSTALLED, IT WILL

SEVERELY DAMAGE THE NAILER.

TO REPLACE DRIVING BLADE (#14):

1. Disconnect the air supply.

2. Remove the four socket head cap screws holding
the Adapter Foot, Foot and Nail Channel Assembly to
the body.

3. Remove the Rubber Bumper.

4. Pull the Driving Blade with pliers until the Piston

is fully extended outward towards the bottom of the
cylinder.

5. Use the 15/16” box wrench supplied to unscrew

the Driving Blade Jam Nut and remove it. Hold the
Piston from turning while unscrewing the Jam Nut

by holding the piston hex with the 1-1/8” box wrench
supplied.

6. Push out the 1/4” diameter blade retaining Dowel

Pin and remove the broken Driving Blade stub.

7. Install a new Driving Blade in the slot and replace
the Dowel Pin. Screw on the retaining Jam Nut using
the same tools. If the Jam Nut becomes worn and

loose after frequent removals, it should be replaced.

8. Check the t, there should be some sideways
movement between the Driving Blade and the Jam

Nut assembly. This is desirable and helps the blade
to align itself with the mating parts.

9. Reassemble the components. Be sure to align
the Driving Blade with the slot in the Adapter Foot

Assembly.
