OPERATIONAL AND SAFETY INSTRUCTIONS: 
 

BE SURE TO READ ALL INSTRUCTIONS BEFORE ASSEMBLING 
AND OPERATING THIS EQUIPMENT. 

 

* All CS Unitec pneumatic saws are designed to be operated @ 90 P.S.I. 
min. (6.2 bar) air pressure, 85 CFM min., with a minimum 1/2” (13 mm) 
I.D. air hose. Using higher pressure to attain more horsepower will 
drastically shorten tool life. 
 
* The Saw motor is factory pre-set at 2900 RPM. Be sure your blade will 
operate at that speed. 
 
* After every 40 hours of operation, or as experience indicates, inject 1 to 
2 cc’s (2-3 pump strokes) of a quality gear grease into the saw’s zerk 
fittings. 

 

 

W  A  R  N  I  N  G  S  ! ! 

 

 

* Always turn off the air supply and disconnect the air supply hose before 
installing, removing, or adjusting any accessory on this tool — especially 
the cutting blade — or before performing any maintenance on this tool.  
Failure to do so could result in serious injury or death! 

 

* P

neumatic tools can vibrate during use. Repetitive motions, 

uncomfortable positions and vibrations can cause injury to hands, fingers, 
or wrists.  

STOP 

using any tool if discomfort, a tingling feeling, or pain 

occurs.  Seek your supervisor’s advice before resuming use.

 

 

* Projectile Hazard

 - Always wear safety glasses to prevent eye injury 

or loss of sight when operating power tools.  

The most important safety 

device for this tool or any power tool is YOU!  

Your care and good 

judgment are the best protection against injury.

 

 

* Hearing loss can result from prolonged exposure to excessive sound 
levels.  

ALWAYS 

use approved hearing protection. 

 

* Dust mask should be worn when using this saw in dry-cutting 
applications. 

 

* Wear safety shoes during equipment use.  DO NOT wear loose clothing 
which could get caught in equipment.
