SAFETY INSTRUCTIONS
Always use approved SAFETY GLASSES and EAR PROTECTION when operating this Nailer. The
operator and others in the work area should always wear approved FRONT and SIDE eye protection
when operating this Nailer. Eye protection will help guard against fl ying nails 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.
Nailer noise ratings are at LPA-1sd=90.6,
LWA-1sd=99.3 and LPA-1s,1m=86.3.
Nailer vibration rating: m/s2=3.05.
Always DISCONNECT THE AIR SUPPLY before making any adjustments, repairing, clearing jams or when the
Nailer is not in use. Do not use on scaff olding or ladders and disconnect nailer from air supply when transporting
between installation areas.
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.
Nailer 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 Nailer and seals may occur. Excess air pressure
can cause the Nailer 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 Nailer.
Nailer 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
Powernailer. 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 nailer. 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 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.
Whenever air is connected to the Nailer, keep body parts away from the nail discharge path.

Read these instructions carefully before you use the Nailer.
1. Loosen 2 hex screws.
2. Raise or lower the FLEX to your wood sample.
3. Match the triangle & 9mm roller to the nail 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 nail pocket.
To use the Powernail Flex Power Roller, adjust the nailer
FLEX foot to a sample of your fl ooring (Figure 1).
When the nailer foot is adjusted to your fl ooring, simply
place the nailer on the fl oor and pull nailer back so the
triangle & 9mm roller catch the edge of the fl oor above
the tongue. Tap the plunger with the rubber-capped
mallet-end to let the Nailer drive and set the nail at the
correct 45 degree angle.
To Load the 445 FLEX Power Roller:
Place up to one stick (100) of Powercleats® (16 gauge)
nails, 2" , 1-3/4" , or 1-1/2" long into the nail channel
feed slot. Pull back the spring loaded nail pusher over
the nails until it contacts the last nail and slowly release
the nail pusher.
To Unload
To remove nails from the nail channel, pull the two
round knobs on the nail pusher together. This will clear
it from the nail path. Then turn the nailer over so the
nails slide out of the channel.
First, loosen the two hex bolts under the FLEX foot with
the Allen Wrench supplied with the nailer. (Figure. 1.)
Next, set the nailer on a sample of your fl ooring.
Use the adjustment lever at the back of the nailer foot to
raise or lower the nailer to the wood.
Match the Adapter Foot triangle & 9mm roller 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 nail pocket, line up the triangle & 9mm
roller at the top of the nail 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 nail is driving into the nail pocket.
OPERATION
Adjust FLEX lever so the triangle & 9mm roller is above the fl ooring tongue
Figure 2.

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.
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 fi lter-regulator-
lubricator is required for proper Nailer performance
and should be placed close to the Nailer per
manufacturer’s recommendations.
The air source must continuously deliver 80 to 110
psi (but not over 120 psi) at 3-1/2 cubic feet of air per
minute to operate the Nailer. Connect a clean air hose
and air regulator to the Nailer.
Check for air supply leaks that waste air and starve the
Nailer of air thereby reducing its performance.
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
Pneumatic Light Air Tool Oil into the disconnected air
line male connector attached to the Nailer.
WARNING: Detergent oil is not recommended and
may damage the seals.
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
fl ooring, walls or furnishings. Dry fi re the Nailer,
without nails, to purge excess oil, before you begin to
nail down fl 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.
PARTS & SERVICE:
When ordering parts include the part number,
part description, Powernailer model and serial
number. Be sure to state the quantity of the
part(s) required. Contact your Powernail Dealer
for the necessary parts or visit our parts store
www.store.powernail.com
WARNING: Never work on the Nailer if the air
line is attached. Always disconnect the air line

16 Gauge Powercleats™
16 GA. Powercleats are designed for the hardwood fl ooring
industry and are FHA and VA approved. Powercleats nails are
superior-quality nails designed to ensure trouble-free nailer
operation and optimum construction results.
Powercleats nails are made from high-quality steel so they
do not bend while being driven into hard fl ooring materials.
They are made with a well-formed set of barbs along each
nail, providing the ultimate holding power. The design aids
in driving them into hard fl ooring materials, which helps to
eliminate split tongues in fl oorboards.
For use on 1/2″- 3/4" Tongue & Groove
