SAFETY INSTRUCTIONS

Always use approved SAFETY GLASSES and EAR PROTECTION when operating this stapler. The
operator and others in the work area should always wear approved FRONT and SIDE eye protection
when operating this stapler. Eye protection will help guard against fl ying staples and debris, which could
cause severe eye injury.

EYE AND EAR PROTECTION should be used to prevent hearing damage when there are high noise
levels in the work area.

ALWAYS use ear plugs with a noise reduction rated at 29 db or highter at a construction site.

Stapler noise ratings are at LPA-1sd=90.6,
LWA-1sd=99.3 and LPA-1s,1m=86.3.
Stapler vibration rating: m/s2=3.05.

Always DISCONNECT THE AIR SUPPLY before making any adjustments, repairing, clearing jams or when the
stapler is not in use. Do not use on scaff olding or ladders and disconnect stapler from air supply when transporting
between installation areas.

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.

Stapler requires an air source that can continuously deliver 80 to 110 psi at 3-1/2 cubic feet of air per minute for
operation.
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.

To prevent fi re or explosion, use only regulated compressed air—do not use bottled gases of any kind (no oxygen
or combustible gasses) to power this Stapler.

Stapler is intended for use installing wood fl ooring and is not to be used for purposes not specifi ed in the
operations manual.

Do not use any nails other than Powernail Powercleats Nails which are specifi cally designed for use in any
Powerstapler. Powercleats Nails are available in various lengths. Contact your Powernail Dealer for Powercleats
Nails.

Use only Powernail replacement parts in the repair or maintenance of this stapler. Parts or repair services are
available from the manufacturer or from agents authorised by the manufacturer. Repairs should be carried out
only by trained service personel in the fi eld of fastener driving tools who will observe proper safety controls while
performing maintenace. Service personel should be qualifi ed to to asses the safe working condition of fastener
driving tools.

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 cleats 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.

Whenever air is connected to the Stapler, keep body parts away from the nail 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.

OPERATING INSTRUCTIONS

Consult the staple depth chart for the appropriate
adapter pad to use with the thickness of fl ooring
you are installing and the selection of Powerstaple®
length.

Rack the fl ooring into place with the rubber end of the
mallet supplied with the Stapler

Place the Stapler Adapter Foot on the tongue-edge of
the fl ooring strip to be stapleed. Be sure the Adapter
Foot is pressed tightly against the edge of the fl ooring
strip above the tongue.

Be sure fl ooring strips are racked tightly. 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.

DO NOT USE THE METAL END OF THE MALLET
TO STRIKE THE PLUNGER, use the rubber capped

end only.
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.

Drywall Dust:

• Using Pneumatic PowerStaplers 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.

The air source must continuously deliver 80 to 110
psi at 3-1/2 cubic feet of air per minute to operate
the Stapler. For operation, 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 110 psi.

Check for air supply leaks that waste air and starve
the Stapler of air thereby reducing its performance.
There should be no orifi ce smaller than 1/4” in the air
path between the Regulator and the Stapler.

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 fl ooring,
walls or furnishings. Dry fi re the Stapler, without staples,
to purge excess oil, before you begin to staple down
fl ooring. Before storing the Stapler, lubricate and cycle
the Stapler in insure internal parts are oil protected from
corrosion.

WARNING: Detergent oil is not recommended and may
damage the seals.

TO LOAD MODEL 445FS:

Place two sticks (90 PowerStaples) into the Staple
Channel feed slot. Pull back the spring loaded Staple
Pusher over the staples until it contacts the last staple
and slowly release the Staple Pusher.

TO UNLOAD MODEL 445FS:

To remove staples from the Staple Channel, pull the two
round knobs on the Staple Pusher together. This will
clear it from the staple path. Then turn the Stapler over
so the staples slide out of the channel.

LUBRICATION:

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

OPERATING INSTRUCTIONS, continued

OPERATING STAPLER:

To use the Model 445FS, simply place the stapler on the
fl oor, pull nailer back so locating ears catch the edge
of the fl oor above the tongue, tap the plunger with the
rubber capped mallet end and let the stapler drive and
set the staple at the correct 45 degree angle.

Adjust stapler by adding shims between the adapter foot
and pad until there is a slight gap between the tongue of
the wood and the locating ears of the adapter foot. See
example 1B and 2A.

PARTS & SERVICE:

When ordering parts include the part number, part
description, PowerStapler model and serial number. Be
sure to state the quantity of the part(s) required. Contact
your Powerstaple Dealer for the necessary parts.

WARNING: Never work on the Stapler if the air line
is attached. Always disconnect the air line from the
Stapler fi rst.

Stapler DISASSEMBLY:

TO REPLACE RUBBER BUMPER (#24):

1.) Disconnect the air supply

2.) Remove the four (4) screws holding the Adapter
Foot, Foot and Staple Channel assembly to the main
Body.

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 Stapler.
Be sure to align the Driving Blade with the slot in the
Staple Channel Assembly while you reassemble the
Stapler.

NEVER FIRE THE Stapler WITHOUT THE RUBBER
BUMPER INSTALLED, IT WILL SEVERELY DAMAGE
THE STAPLER.

CHANGING A DRIVING BLADE (#15):

1.) Disconnect the air supply.

2.) Remove the four socket head cap screws (#40)
holding the Adapter Foot (#60), Foot (#30) and Staple
Channel Assembly (#27) to the body.

3.) Remove the Rubber Bumper (#24).

4.) Pull the Driving Blade (#15) with pliers until the
Piston (#20) is fully extended outward towards the
bottom of the cylinder.

5.) Use a 15/16” box wrench (Part #:
unscrew the Driving Blade Jam Nut (#22) and remove
it. Hold the Piston from turning while unscrewing the
Jam Nut by holding the piston hex with a 1-1/8” box
wrench
(Part #:

6.) Push out the 1/4” diameter blade retaining Dowel
Pin (#14) and remove the broken Driving Blade stub.

7.) Install a new Driving Blade in the slot and replace
the Dowel Pin (#14). Screw on the retaining Jam Nut
(#22) using the same tools. If the Jam Nut becomes
worn and loose after frequent removals, it should be
replaced.

8.) Check the fi 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.
