Safety Instructions
WARNING!
Risk of serious personal injury or death.
Read and follow instructions for proper use of this product.
Because of the harsh environment to which Band Saws are exposed, it is necessary
that you carefully follow all instructions accompanying your saw and its cutting
attachments. In particular, the following instructions are highlighted.
1. Plan ahead - lay the work out before starting. Always work in a steady manner.
Fatigue leads to carelessness and accidents. Never operate your tool while
you are under the influence of medication, alcohol, or other drugs.
2. Keep your work area clean and uncluttered and keep children and
unnecessary personnel away from your saw and work area.
3. Wear proper clothing. Clothing which is too tight or too loose is not
suitable; it can restrict your movements or be caught up by the saw band.
4. Protect your head and hair, eyes and ears, hands, legs and feet.
° Wear a hard hat, ear protectors and safety glasses
° Wear non-slip gloves to protect your hands
° Wear safety boots to protect feet and legs
5. Always disconnect power hose before attaching a saw band or working on the saw.
To disconnect Electric Motor unplug the cord from the pwoer outlet.
To disconnect Air Motor shut main air hose valve.
Open air valve to decompress hose before disconnecting it.
6. Do not operate the saw unless your body and weight are firmly balanced and secure.
Never use the saw while leaning from a ladder, scaffold or other structure. Grab the
saw with both hands during use. Keep hands and other body parts away from
cutting area. Exercise extreme care to prevent hands from contacting the saw band.
7. No obstructions. Be certain the object being cut does not contain electrical wires.
Use clamps or make sure the material to be cut is firmly held to prevent movement.
8. Slurry is very slick. Remove or control to prevent yourself, or others, slipping
while cutting.
9. Never carry the band saw with the motor running! Do not carry the saw with
the finger on or nearby the trigger switch or valve lever.

10. Be alert for pieces which might fall down.
(Solid steel of 4“ dia. and 12“ length weighs about 40 lbs !)
11. Avoid sparks in hazardous environment - created by the saw band.
12. Use saw only with secured closed cover.
13. Do not operate saw with a damaged, modified, or broken cover.
ELECTRICAL SAFETY
1. Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or
modify the plug in any way. Do not use any adaptor plugs. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded. If the
tools should electrically malfunction or breakdown, grounding provides a low
resistance path to carry electricity away from the user.
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
3. Don’t expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from
an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
5. When operating a power tool outside, use an outdoor extension cord marked W-A
or W. These cords are rated for outdoor use and reduce the risk of electric shock.

Selection of Saw Band
Which saw band to use
In general, select a saw band which will allow at least two teeth to be
engaged in the material thickness. The thinner or the harder the material,
the finer the saw band teeth.
Ask your dealer for the right selection of saw bands.
WARNING:
Exercise extreme care to prevent hand from contacting the saw band
USE OF LUBRICANTS
NEVER USE LIQUID COOLANT WITH YOUR BAND SAW. Damage to
the blade guide bearings or rubber tires on the pulleys may result.
Warning: LIQUID COOLANTS CAN INCREASE THE RISK OF
ELECTRICK SHOCK. Use only stick wax to lubricate the blade.
CS Unitec’s “Lube Wax“ is availabe as an accessory and is recommended when
cutting aluminum, brass and thick materials. Cast iron should be cut dry.
With the saw running, apply the wax momentarily to both sides of the blade.
Reapply wax intermittently as needed.
Warning: EXCERISE EXTREME CARE TO PREVENT HANDS FROM
CONTACTING THE BLADE.
After prolong cutting, the wax will cling to the pulleys of your Band Saw. This
does not affect the operation of the machine. All that is necessary is to
disconnect the machine from the power source adn wipe the wax from the
pulleys.

General Operating Instructions
AIR BAND SAW
1) Air Supply
Compressor must be able to supply the saw with at least 1,00 m³/min (35 cfm)
clean and dry air at 7 bar (100 PSI).
Install a service unit, if necessary, but in any case use an oiler.
Minimum air hose diameter 13 mm (1/2“).
Blow air hose clear and connect it to the cleaned saw air inlet
(Check screen).
2) Lubricator
Install service units or line oiler!
Check and if necessary fill with resin- and acid-free SAE 5 W to SAE 10 W
oil.
In winter or when using very moist air, use antifreeze lubricant, such as
“Kilfrost”, “BP Energol AX 10” or “Kompranol N 74”.
3) Remember safety instructions and cutting hints!
ELECTRIC BAND SAW
1) Model 5 6047 0010 is designed for A.C. current only. Refer to the specification plate on your tool
to proper voltage and current rating.
CAUTION: Do not operate your tool on a current on which the voltage is not within
correct limits. Do not oeprate tools rated A.C. on only D.C. current. To
do so may seriously damage the tool.
EXTENSION CORD SELECTION
If an extension cord is used, make sure the conductor size is large enough to prevent excessive voltage
drop which will cause loss of power and possible motor damage. A table of recommended extension
cord sizes will be found in this section. This table is based on limiting line voltage drop to 5 volts (10
volts for 230 volts) at 150% of rated amperes.
If an extension cord is to be used outdoors it must be marked with the suffix W-A or W following the
cord type designation. For example – SJTW-A to indicate it is acceptable for outdoor use.

Maintenance
Only proper maintenance can ensure constant performance, reduction in wear and thus,
a decrease in operating costs and an increase in service life.
AIR BAND SAW
SERVICE LIFE and PERFORMANCE of the Air band saw are determined by
a) Degree of air purity
Blow the air hose clear before connecting it to the saw.
Install dirt and water separators upstream of the saw, if it is not possible
to prevent the formation of rust and water condensation in the air distribution lines.
b) Lubrication
The motor must be lubricated by a line oiler or service unit.
Fill the lubricator with resin- and acid-free „SAE 5 W“ to „SAE 10 W“ oil.
Heavy oils will cause the vanes to stick, thereby making the motor difficult to start
and impairing its performance.
Optimum lubrication significantly prolongs service life. We therefore
highly recommend to install service units (combined filters, regulators and
lubricators) upstream of the saw.
c) Maintenance
Regularly check and clean the air inlet screen.
Replace wear parts - in particular the motor vanes - when necessary.
Vanes are considerd worn if their width is less than 9.7 mm (3/8“)
ELECTRIC BAND SAW:
For your continued safety and electrical protection, brush inspection and replacement
on this tool should ONLY be performed by an Authorized CS Unitec Service Station.
At approximately 100 hours of use, take or send your tool to your nearest authorized
CS Unitec Service Station to be thoroughly cleaned and inspected. Have worn parts
replaced and lubricate with fresh lubricant. Have new brushes installed, and test the
tool for performance.
Any loss of power before the above maintence check may indicate the need for
immediate servicing of your tool. DO NOT CONTINUE TO OPERATE TOOL
UNDER THIS CONDITION. If proper operating voltage is present, return your tool
to the service station for immediate service.
Keep Tool Clean
Periodically blow out all air passages with compressed air.
Caution: Wear safety glasses while using compressed air.
Remove wax and chip buildup from drive pulleys and blade guides.
All plastic parts should be cleaned with soft damp cloth. Never use solvents
to clean plastic parts. They could possibly dissolve or otherwise damage the
material.
After use, clean the saw. Rinse it with light oil or provide alternate corrosion
protection after having worked in wet surroundings.
