Always wear approved front and side 

EYE PROTECTION

when operating this Nailer. Others in the work area 

should also wear front and side 

EYE PROTECTION

. Eye 

protection will help guard against flying nails and debris, 

which could cause severe eye injury.

EAR PROTECTION

 may be required to prevent hearing 

damage when there are high noise levels in the work 

area.
Always 

DISCONNECT THE AIR SUPPLY

 before making 

any adjustments, repairing, clearing jams or when the 

Nailer is not in use.
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
Use only regulated compressed air, do not use bottled 

gases of any kind to power this Nailer. Normal air 

pressure should not exceed 110 psi or damage to the 

Nailer and seals may occur. Excess air pressure can 

cause the Nailer to explode.

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.

DO NOT USE THE METAL END OF THE MALLET TO 

STRIKE THE PLUNGER,

 use the rubber capped end 

only.
Never place any part of the body in the discharge path 

of the Nailer when air is connected to the Nailer. Always 

connect air hose to unloaded Nailer to prevent any 

accidental discharge from occurring.
Never leave the Nailer unattended while it is connected 

to an air supply.

DESCRIPTION

OPERATION

TO PREVENT ACCIDENTAL INJURIES:

The Powernailer® Model 50P Pneumatic Nailer is the 

latest model designed to bring Powernail quality to a 

pneumatic nailer. For those looking for the ease of use of 

a pneumatic tool, the Powernailer® Model 50P designed 

for use with only 1" , 1-1/4", 1-1/2" and 1-3/4" (18 gage) 

Powercleats® nails provides several distinct advantages. 

The Model 50P can nail down 3/8", 1/2", 5/8" and 

some exotic 3/4" tongue and groove hardwood flooring 

through the use of easy to change, no mar pad and 

shims. For a superior pneumatic Nailer, look to the 

company that has been the industry’s quality leader for 

over 50 years, POWERNAIL® COMPANY, INC.

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 Model 50P LS or SS 

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 

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.

Read these instructions carefully before you use the Nailer.
