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 fi 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 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.

Read these instructions carefully before you use the Nailer.
OPERATION
WARNING: Do not use any nails other than Powernail Powercleats® (18 gage) nails, which are specifically
designed for use in the Model 50P Powernailer.
Powercleats® (18 gage) nails are available in 1", 1-1/4", 1-1/2" or 1-3/4" lengths to accommodate 3/8",
1/2", 5/8" and some exotic 3/4" tongue and groove hardwood flooring. Contact your Powernailer® dealer for
Powercleats® nails.
To use the Model 50P, simply place the nailer on the
floor, pull nailer back so locating ears catch the edge of
the floor above the tongue, pull the safety trigger and
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.
To Load the Model 50P
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.
To Unload the Model 50P
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.

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 Mobile DTE Light Oil, supplied with your
Nailer, 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.
WARNING: Never work on the Nailer if the air line
is attached. Always disconnect the air line from the
Nailer first.

of the Return Cylinder when you reassemble the
Driving Blade Assembly.
2. Wipe off the O-Ring Gasket seal surface and
lubricate it generously with the supplied lubricant,
Mobile DTE Light air tool oil lubricant.
REASSEMBLING THE NAILER:
1. Be sure the Rubber Seat, Support Ring and
Cylinder are installed in the Body and are facing the
correct direction.
2. All seal surfaces must be clean and lubricated
generously with the supplied Mobile DTE Light air
tool oil lubricant.
Replace any part that shows signs of wear.
3. Use care when installing the seals into their
respective cavities. Be sure the Seals are contained
in their groove and do not come out as the parts slide
together. Generous cavity lead in chamfers have
been provided to help Seal installation.
4. Carefully insert the Piston Rod into the Return
Cylinder and screw the Piston onto the rod. Be sure
the Piston is facing the correct way, ears up, hex
down.
5. Assemble the Driving Blade, Dowel Pin and Jam
Nut on to the Piston Rod.

in the Foot before the Nailer is closed up.
13. NEVER FIRE THE NAILER WITHOUT
THE RUBBER BUMPER INSTALLED, IT WILL
DAMAGE THE NAILER BEYOND REPAIR.
TO CLEAR A NAIL JAM:
1. It helps to tap the Driving Blade back to the
retracted position before trying to remove a jammed
nail. A spare Driving Blade works best for this.
2. Try to pull the jammed nail out of the gate with
a pair of long nose pliers. If this does not work
remove the four (4) cap screws holding the Foot,
Gate and Nail Channel Assembly together.
3. Separate the Foot and Gate with a screw driver
just enough to clear out the jammed nail.
4. Put thread locking compound on all screws and
reassemble the components.
