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. 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.

OPERATING INSTRUCTIONS
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 from the Nailer
fi rst.
LOADING CLEATS INTO THE NAIL CHANNEL:
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.
UNLOADING CLEATS:
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.
OPERATING NAILER:
To use the Model 445, simply place the nailer 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 Nailer drive and
set the nail at the correct 45 degree angle.
Adjust nailer 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.
