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,

OPERATING INSTRUCTIONS
Read these instructions carefully before you use the Stapler.
1. Loosen 2 hex screws.
2. Raise or lower the FLEX to your wood sample.
3. Match the
9mm rollers to the staple pocket.
4. Tighten 2 hex screws.
5. Test wood sample with new adjustment.
Hex Allen Wrench
FLEX
Adjustment Lever
Figure 1.
FLEX Power Roller Foot Adjustment:
Wood varies from one manufacturer to the next. The
diff erent wood profi les may be due to height and
length of the fl ooring tongue and whether or not there
is a staple pocket.
To use the Powernail Flex Power Roller, adjust the
stapler FLEX foot to a sample of your fl ooring (Figure 1).
When the stapler foot is adjusted to your fl ooring, simply
place the stapler on the fl oor and pull stapler back so the
9mm rollers catch the edge of the fl oor above the tongue.
Tap the plunger with the rubber-capped mallet-end to
let the stapler drive and set the staple at the correct 45
degree angle.
To Load the 445FS FLEX Power Roller:
Place up to two sticks (90) of Powerstaples® (15.5
gauge) staples, 2" , 1-3/4" , or 1-1/2" long 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
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.
First, loosen the two hex bolts under the FLEX foot with
the Allen Wrench supplied with the stapler. (Figure. 1.)
Next, set the stapler on a sample of your fl ooring.
Use the adjustment lever at the back of the stapler foot
to raise or lower the stapler to the wood.
Match the Adapter Foot 9mm rollers so that it is pointing
into the 90° angle created
by the tongue and the top of the wood (see Figure 2).
For wood with a staple pocket, line up the 9mm rollers
at the top of the staple pocket.
When the adjustment lever is in the correct position
for your wood sample, tighten the two hex bolts to
lock the FLEX foot into place.
Always check your adjustment with a sample to
ensure the staple is driving into the staple pocket.
Figure 2.
Adjust FLEX lever so the 9mm rollers are above the fl ooring tongue

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) cap 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
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.
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
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.
