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 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 scaffolding 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 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 ooring and is not to be used for purposes not specied in the operations
manual.
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 any nails other than Powernail Powercleats Nails which are speci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 eld of fastener driving tools who will observe proper safety controls while
performing maintenace. Service personel should be quali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. 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.

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 Locating Ear to the nail pocket.
4. Tighten 2 hex screws.
5. Test wood sample with new adjustment.

Adjustment Lever
Figure 1.
FLEX Foot Adjustment:
Wood varies from one manufacturer to the next. The
different wood proles may be due to height and
length of the ooring tongue and whether or not there
is a nail pocket.
To use the Powernail Flex, adjust the nailer FLEX foot to
a sample of your ooring (Figure 1).
When the nailer foot is adjusted to your ooring, simply
place the nailer on the oor and pull nailer back so
locating locating ears catch the edge of the oor above
the tongue. Pull the safety trigger and 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 gage)
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 ooring (see
Figure 2).
Use the adjustment lever at the back of the nailer foot to
raise or lower the nailer to the wood.
Match the Adapter Foot Locating Ear so that it is
pointing into the 90° angle created
by the tongue and the top of the wood (see Figure 3).
For wood with a nail pocket, line up the Locating Ear
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

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
manufacturer’s recommendations.
The air source must continuously deliver 80 to 110
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
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.
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.
WARNING: Never work on the Nailer if the air
line is attached. Always disconnect the air line
from the Nailer rst.
