CS Unitec Model CSR-150 

20” Walk-Behind Pneumatic Concrete Saw 

 

Congratulations on your purchase. We consider the CS Unitec 
Model CSR-150 20” pneumatic concrete saw to be among the finest 
concrete saws in the world. It has been engineered to withstand the 
construction environment and will last many years with the proper 
care and maintenance. 

 
The heart of the CSR-150 is a newly developed pneumatic motor coupled 
with a heavy-duty gear drive. Our motor runs at a higher speed than most 
conventional saws and attains its amazing horsepower from this optimum 
speed.  The gear drive then reduces the speed attaining the maximum 
horsepower. 
 

FIRST AND FOREMOST: 

 

The use of blades, oil, and replacement parts other than those supplied by 
CS Unitec may compromise your saw’s performance, operator safety, and 
also lead to higher-than-normal maintenance and repair requirements. 

 
ADDITIONALLY: 

 

1. Pneumatic tool lubrication is critical to achieving the maximum 

performance and life from your pneumatic tool.  We strongly suggest 
lubrication through the air inlet.  When using an in-line oiler, install it 
as close to the motor as possible.  One drop of oil per minute is 
adequate lubrication for most pneumatic motors. 

 

2. It is also recommended that, when the saw is going to be shut down at 

the end of the day, the air line be shut off and the saw disconnected.  
Pour approximately 1/2 oz. of CS Unitec Air Tool Lubricant into the 
line, then reconnect the line to the saw and give the throttle about a 2-
second burst.  This procedure will coat the internal parts of the motor 
displacing any moisture and will prevent any rust or corrosion. 

 

3. All CS Unitec pneumatic tools should be operated and maintained in 

accordance with American National Standards Institute Safety Code 
for Portable Air Tools (ANSI B186.1) and any other applicable safety 
codes and regulations.  B186.1 information is available from the 
National Standards Institute, Inc., 11 West 42
