PRE-OPERATING INSTRUCTIONS
Check air supply for correct pressure (90 PSI min.) and
sufficient flow (85 CFM min.). Daily, blow out air line to
dislodge any debris, moisture or foreign matter from the air
line and the compressor. WARNING! Use extreme caution
when blowing out pressurized air lines and or air hoses.
Expelled particles can cause severe injury. Connect water
hose for wet-cutting applications, or vacuum hose for dry-
cutting applications. Connect air supply hose to saw. Check
for leaks.
OPERATING INSTRUCTIONS
Under no circumstances should this saw be operated by
personnel who have not been trained in the operation of
saw cutting.
Start with the saw positioned above the surface being cut.
Squeeze the throttle. When the saw has attained full speed,
slowly engage it into the cut. Because the saw cuts in a
clockwise direction, it will pull itself into the cut. A small
amount of resistance should be applied when first entering
the cut. Do not under any circumstance force the blade into
the cut, as forcing could bend or break the blade. When
finishing the cut, slowly raise the saw until the blade is clear
of the cut. Release the trigger and let the motor come to a
complete stop.

CS Unitec Hand-Held Pneumatic Concrete Saw
Congratulations on your purchase. We consider the CS Unitec
Hand-Held Pneumatic Concrete Saw to be among the finest
concrete saws in the world. It is engineered to withstand the
construction environment and will last many years with the
proper care and maintenance.
The heart of the pneumatic hand-held saw 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 torque.
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
