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.

WARNINGS!!!
•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!
•Pneumatic 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.

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

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 PSI min. (6.2 bar) air pressure 100 psi
maximum, 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.
•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.
•Check the area to be cut; be sure it is free of all loose
debris, and be sure no one is standing in the cut line.
•Use only CS Unitec-approved diamond blades that have
been rated for this saw’s R.P.M. Inspect all blades for
damage before use. Do not under any circumstance use
a bent or warped blade, or a blade with a missing
segment, as an out-of-balance condition could result in
the blade coming apart.
•Always check arbor bearing for end play.
•Check that the guard is secure and undamaged.
•Check to see that all nuts and bolts are tight.
•Never cut material for which the blade is not designed.
•Do not start, run or operate the equipment near
combustible materials.

ASSEMBLY INSTRUCTIONS
1. Install blade. This saw rotates in a clockwise direction
when viewed from the right side of the saw. Be careful
that the arrow on the blade goes in the same
(clockwise) direction. Place blade on the hub of the
inner flange and then secure the outer flange and
5/8”-11 left-hand nut. Use the two wrenches supplied
to tighten the blade, and spin the blade by hand to see
that it is running true. Check that all nuts and bolts are
tight.
2. Connect the air supply
3. Connect the clear water hose from the handle
assembly to the water spray fitting on top of the
guard.
Saws returned to CS Unitec for warranty consideration must
be shipped prepaid, along with proof of date of purchase, a
brief description of the problem, and a CS Unitec Return
Goods Authorization (RGA) number issued by CS Unitec’s
Customer Service Department.
