If the tool is not used with an in-line lubrication system on 
the air  supply it is necessary to periodically lubricate the 
tool with air tool lubrication.

USE  ONLY  THE  AIR  TOOL  LUBRICANTS  SUPPLIED  WITH 
THE  TOOL. 

Do  not  use  other  lubricants  as  they  may 

damage the tool.

Do not use detergent oil, WD-40, transmission fluid, motor 
oil, or other lubricants not specifically designated as air tool 
lubricants. These lubricants will cause accelerated wear to 
the  seals,  o-rings,  and  bumpers in the  tool,  resulting  in 
poor tool performance and frequent maintenance.

2-3 Drops of 

Air Tool Lubricant

CONNECTING AIR SUPPLY

Never use oxygen or other bottled gases as a power source. 

Explosion may occur. Combustible gases and other bottled 
gases are dangerous and may cause the tool to explode.

Never connect the tool to an air source that is capable of 
producing  air  pressure  exceeding  600PSI. 

Excessive 

pressure can cause abnormal operation or cause the tool to 
be burst, resulting in personal injury.

ADJUSTING AIR PRESSURE

Adjust  the  air  pressure  at  recommended  operating 
pressure 180-330PSI 

The correct air pressure is the lowest pressure which will 
do  the  job.  Using  the  tool  at  a  higher  than  required  air 
pressure  unnecessarily  over  stresses  the  tool. 

according to the length of nails and 

the hardness of workpiece.

Don't 

exceed330PSI.

Light weight, magnesium body reduces working fatigue.
A  rotating  switch  that  can  be  set  to  rapid-fire  or 
sequential fire.
Easy clear jam clearing.
Tool free depth of drive.
Nail lockout prevents dry fires.
Fast fire speed.
No-Mar tip protects work surface.

Under  low  use,  lubricate  once  a  day.  Under  heavy  use, 
lubricate  twice  a  day.  To  lubricate,  insert  2-3  drops  of 
lubricant  into  the  air  supply  fitting  attached  to  the  tool 
handle (FIG 2). Using too much oil will cause it to collect in 
the tool and be noticeable in the exhaust.

ASSEMBLY/INSTALLATION

Follow  the  instructions  below  to  prepare  your  tool  for 
operation.

All tool operators and their immediate supervisors must 
become  familiar  with  the  operator  safety  instructions 
before operating the tool. 
Included  with  each  tool  are  one  copy  of  these 
Operating/Safety Instructions. Keep this publications for 
future reference.
Install a filter, regulator, lubricator unit and moisture trap 

on  your  air  delivery  system  per  the  manufacturer's 
instructions  for  these  devices.  Additionally,  install  a 
pressure  gauge  as  close  as  practical  to  the  tool, 
preferably within 10 feet.
Select  hoses  with  a  minimum  inner  diameter  of  1/4 
inches and a maximum length of 100 feet.

To  reduce  the  risk  of  injury  from  a  hose  bursting,  select 
hoses that are rated at least 600PSI.

Select fittings that are appropriate size for the selected 
hoses. The tool and air hose must have a hose coupling 
so that all pressure is removed from the tool when the 
coupling joint is disconnected.

Never  use  non  relieving  couplers  and/or  female  quick 
disconnect couplings on the tool.

 Non relieving couplings 

and female couplings will trap high pressure air in the tool 
when the air line is disconnected. This will leave the tool 
charged with enough air after it has been disconnected to 
drive  a  nail.  Only  MALE  pneumatic  type  air  connectors 
should be fitted to the tool, so that high pressure air in the 
tool  is  vented  to  atmosphere  as  soon  as  the  air  line  is 
disconnected.

Set the regulator at the air delivery system to a PSI that 
falls within  the tool's operating  range  of 180-330PSI. 
The correct pressure is the lowest pressure that will do 
the job.
