USER-MAINTENANCE 

INSTRUCTIONS

  Procedures not specifically 

explained in this manual 

must be performed only by a 

qualified technician.

 

TO PREVENT 

SERIOUS INJURY 

FROM ACCIDENTAL 

OPERATION: 

Turn off the tool, detach the 

air supply, safely discharge 

any residual air pressure in 

the tool, and release the 

Trigger before performing any 

inspection, maintenance, or 

cleaning procedures.
TO PREVENT SERIOUS 

INJURY FROM TOOL 

FAILURE: 

Do not use damaged 

equipment.  If abnormal 

noise, vibration, or leaking 

air occurs, have the problem 

corrected before further use.

Cleaning, Maintenance, and 

Lubrication

Note:

  

Anytime inspection, maintenance 

and cleaning are done:

1. 

Disconnect the Floor Nailer from 

its air supply.

2. 

Empty the Magazine (71) complete-

ly.

3. 

Try to fire the Nailer into a piece of 

scrap wood or flooring to ensure 

that it is disconnected and inca-

pable of firing any nails/staples. 

4.  Inspect the air supply screen located 

in the End Cap (82) before each use. 

Clean or replace as necessary. Dirt 

in the air supply is a major cause of 

pneumatic tool wear. Use a filter in 

the compressed air system for better 

performance and longer tool life. The 

filter must have adequate flow capac-

ity for the specific application.

5.  Clean the external parts of the Nailer 

with a clean cloth and mild detergent 

or non-flammable solvent.  Then dry.

6.  Store in a clean, dry and safe location 

out of reach of children. 

 

 

 

All maintenance, service or repairs 

not listed in this manual are only 

to be attempted by a qualified ser-

vice technician.
