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 flying 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 fire 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 flooring and is not to be used for purposes not specified 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 fire 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 specifically 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 field of fastener driving tools who will observe proper safety controls while
performing maintenace. Service personel should be qualified 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. POWERNAIL COMPANY, INC.

Figure 1.
FLEX Tri-Glide Foot Adjustment:
Wood varies from one manufacturer to the next. The
different wood profiles may be due to height and
length of the flooring 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 flooring (see instructions below).
When the nailer foot is adjusted to your flooring, simply place the nailer on the floor and pull nailer back so the
locating ears (Figure 3) catch the edge of the floor above the tongue. Pull the safety trigger and hit 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 Powernail Flex:
Place up to one stick (100) of Powercleats® (18 gage) nails, 1" , 1-1/4" , 1-1/2" or 1-3/4" 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.
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 flooring
Use the adjustment lever at the back of the nailer foot to
raise or lower the nailer to the wood.
Match the Adapter Foot Triangles 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 Triangles 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 so the Triangles
sit slightly above flooring tongue

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 filter-
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
flooring, walls or furnishings. Dry fire the Nailer,
without nails, to purge excess oil, before you begin to
nail down flooring. 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 service.
