SAFETY INSTRUCTIONS
When operating this Nailer, the operator and others in the work area should ALWAYS wear approved
SAFETY GLASSES, with front and side eye protection. Eye protection will help guard against flying
nails and debris, which could cause severe eye injury.
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 higher at a
construction site.
Noise characteristic values in accordance with ENxx1:
A-weighted single-event sound pressure level at operator’s position: LPA, ls94dBA
A-weighted single sound pressure level:LpA,ls,lm89dBA
Vibration characteristic values in accordance with ISO 8662, PART II
Weighted root mean square acceleration 3.2m/s²
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 70 to 100 psi at 3-1/2 cubic feet of air per minute
for operation.
Normal air pressure should not exceed 100 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.
Do not use any nails other than 18 gauge straight brad finish nails which are designed specifically for your
nailer.
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 authorized 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 maintenance. Service personel should be qualified to assess the safe working condition of
fastener driving tools.
Always make sure nailer is empty of nails before connecting an air hose, so as to prevent any accidental
discharge from occurring. ONLY CONNECT AIR TO AN UNLOADED NAILER.
Do not depress the trigger when loading. If the fasteners are jammed, disconnect the tool from the air supply
before you remove the jammed nails.
Never place any part of the body in the discharge path of the Nailer when air is connected to the
Nailer. Never point the tool at yourself or others, even if the tool is not loaded. For safety, keep out
of reach of children. Never leave the Nailer unattended while it is connected to an air supply.
Do not fire into hard materials or attempt to use on hard or brittle material such as concrete, steel
or tile. Before using this tool, carefully check that all parts are working correctly. Do not use the tool if it is not
operating correctly, check for causes and adjust as necessary for proper operation. When not in use, the tool
should be cleaned, fully assembled and then stored in a dry location. This will extend the life of the tool and
reduce any oxidation.

OPERATION
APPLICATIONS: The Model BR50 nails from 1/2” to 1-3/4” board and trim.
*Only use tool for its intended purposes. Drive fasteners into work surfaces only;
never into materials too hard to penetrate.
Single-fire Procedure
1. Set the nailer to the work surface with the nose pressed down
to release the safety.
2. Squeeze the trigger once for single-fire operation.
“Bump-fire” Procedure
1. First squeeze and hold the trigger in the fire position.
2. Then push nailer-nose to the surface you wish to nail. The
nailer will fire each time the nailer nose is pushed to the work
surface while keeping the trigger in the fire position.

OPERATION, continued...
QUICK
CONNECTOR
CONNECTING THE TOOL TO AN AIR SUPPLY
Your air tool is fully assembled when you
receive it. Before using it, attach the air line
and desired air system accessories. Be
sure the air hose is depressurized when
installing or removing adapters to the air
line. To prevent misfire, do not connect air to
a loaded nailer.
AIR HOSE
Figure 1
1. An automatic airline oilier is recommended but oil may be added
manually before every operation or after about 1 hour of continuous
use.
2. Place two (2) drops of air-tool oil (figure 2) into the air plug at the
rear of the nailer. If you are using an automatic in-line oiler, check
and add oil if necessary.
3. Turn your compressor on and set the compressors pressure
regulator to the proper pressure for the size and type of fastener
being used. Normal operating pressure should be adjusted between
70-100 psi based on fastener and wood being used.
Figure 2
4. Connect the tool to the air supply (Figure 1).
OPERATING TIPS
Before using this tool, carefully check that all parts are working correctly. Do not use
the tool if it is not operating correctly, check for causes and adjust as necessary for
proper operation.
Secure your work. Use clamps or a vise to hold your work project in place. It is safer
than using your hands and it frees both hands to operate tool.
Do not drive fasteners on top of other fasteners or with tool at too steep of an angle; the
fasteners may ricochet and injure someone.
Do not drive fasteners too close to the edge of the work surface. The work piece is likely
to split and the fastener could fly free or ricochet and injure someone.
Do not fire into hard materials or attempt to use on hard or brittle materials such as
concrete, steel or tile.
