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 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 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.
Nailer is activated by striking the plunger. Do not work on scaffolding, ladders, elevated
or uneven surfaces where the nailer could fall and self-activate. Do not leave air
attached to the Nailer when moving from one install location to another.

OPERATION
Read these instructions carefully before you use the Nailer.
To use the Powernail 50P Flex, adjust the nailer FLEX foot to a sample of your fl ooring (see instructions below).
When the nailer foot is adjusted to your fl ooring, simply place the nailer on the fl oor and pull nailer back so the
triangles (Figure 2) catch the edge of the fl oor above the tongue. Hit the plunger with the rubber-capped mallet-end
to let the Nailer drive and set the nail at the correct 45 degree angle.
FLEX
FLEX Tri-Glide Foot Adjustment:
Wood varies from one manufacturer to the next. The
different wood profi les may be due to height and
length of the fl ooring tongue and whether or not there
is a nail pocket.
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.
Figure 1.
Adjustment Lever
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.
Hex Allen Wrench
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.
Figure 2.
Set the nailer on a sample of your fl ooring.
Raise the nailer foot above the tongue
to line up the nail pocket.
Adjust so the Triangles
sit slightly above fl ooring tongue

OPERATION, continued...
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 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.
