SAFETY INSTRUCTIONS FOR POWER TOOLS
1. KNOW YOUR POWER TOOL. Read owner’s manual carefully.
Learn its applications and limitations as well as specic potential
hazards particular to this tool.
2. KEEP WORK AREA CLEAN. Cluttered areas and benches invite
accidents.
3. AVOID DANGEROUS ENVIRONMENTS. Keep work areas as dry
as possible. Do not use tool in presence of ammable liquids or
gases. Keep the area well lit.
4. KEEP CHILDREN AND VISITORS AWAY. All visitors should be kept
a safe distance from the work area. Keep out of reach of children.
5. DON’T FORCE TOOL. It will do the job better and safer at the rate
for which it was designed.
6. WEAR PROPER APPAREL. Do not wear loose clothing or jewelry
as it can get caught in moving parts. Rubber gloves and insulated
non-skid footwear are recommended. Wear protective covering to
contain long hair.
7. WEAR PROPER EYE PROTECTION. All users and bystanders
must always wear proper personal eye protection which conform with
ANSI/ISEA Z87.1 (CAN/CSA Z94.3). Also use a face or dust mask if
operation is dusty. Always wear certied safety equipment.
8. WEAR PROPER EAR PROTECTION. All users and bystanders
must wear proper personal ear protection which conforms with ANSI
S12.6 (S3.19) hearing protection.
9. WEAR PROPER RESPIRATORY PROTECTION. All users and
bystanders must wear proper personal respiratory protection. Always
use NIOSH/OSHA approved respiratory protection appropriate for the
dust exposure.
Warning: Some dust created by power sanding, sawing, grinding, drilling,
polishing and other construction activities contains chemicals known to the
State of California to cause cancer, birth defects, or other reproductive harm.
Some examples of these chemicals are:
- Lead from lead-based paints
- Crystalline silica from bricks, cement and other masonry products, and
- Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure, work in a well ventilated area, and
work with approved safety equipment, such as dust masks that are specially
designed to lter out microscopic particles.
To familiarize with the risks associated with a material, consult with your
employer, manufacturer/supplier and government agencies regarding the
hazards of the materials and their recommendations to protect yourself.
10. DON’T ABUSE WATER SUPPLY HOSE. Don’t carry tool by supply
hose or expose to trafc areas where it can be crushed.
11. ALWAYS SECURE WORK PIECE. Use clamps or a vise to hold
work. It’s safer than using your hand and it frees both hands to
operate tool.
12. DON’T OVERREACH. Keep proper footing and balance at all times.
13. DISCONNECT TOOLS WHEN NOT IN USE. Always disconnect
tool before servicing when changing blades.
14. REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of
checking to see that keys and adjusting wrenches are removed from
tool before turning it on.
15. MAINTAIN TOOLS WITH CARE. Keep tools clean at all times for
best and safest performance. Follow instructions for lubricating and
changing accessories. Keep handles dry, clean and free of oil or
grease. Inspect moving parts for alignment and binding as well as
for breakage and improper mounting.
16. AVOID ACCIDENTAL STARTING. Do not carry a “connected” tool,
or make adjustments, or change discs without making sure the tool
is disconnected from the air supply.
17. USE ONLY RECOMMENDED ACCESSORIES. The use of any
accessories other than what is listed or recommended for this
particular tool may be hazardous.
18. KEEP HANDS AWAY FROM ALL MOVING PARTS.
19. USE SIDE HANDLES. Supplied with tool for control and safety.
20. STAY ALERT. Watch what you are doing and use common sense.
Do not operate tool when you are tired, or under the inuence of
medication or alcohol.

ADDITIONAL PRECAUTIONS FOR USING
THE PNEUMATIC STONE CUTTER
In addition to the general safety notes described on the preceding pages,
please read and observe the following precautionary notes before using
the pneumatic stone cutter.
DANGER!
INSTRUCTIONS
Alpha Professional Tools® provides the highest quality parts and manufactur-
ing techniques in the manufacture of this tool. In order to obtain the maximum
effectiveness and provide the highest degree of safety, it is necessary to
review and follow these instructions carefully before using the tool.
SAFETY ADVICE
• Please note safety instructions on Page 4-5.
• Always disconnect the air line before making any changes to the set-
tings or carrying out maintenance.
• Keep water and air lines clear from working range of the machine. These
lines should always lead away from you and behind the operating area.
• Before use, check the machine, hose and ttings for any damage or
material fatigue, only authorized service agents should carry out repairs.
• Always wear safety glasses and respiratory protection when working
with this machine. It is further recommended to wear safety gloves,
apron, as well as sturdy non-slipping shoes.
• Only use saw blades whose permitted speed is at least as high as the
highest no-load speed of the machine.
• Be sure saw blade ts the tool properly and securely. Do not modify the
tool to force t the blade. For example, do not remove blade guard.
• Check blades before use. The saw blade must be properly mounted
and turn freely. Perform a test run for at least 30 seconds without any
load. Do not use damaged, out of round or vibrating blades.
• Immediately switch off the machine in case of considerable vibrations
or if other malfunctions occur. Check the machine in order to nd out
the cause.
• Always use and store the saw blades according to the manufacturer’s
instructions. The ange bolt must be tightened before starting to work
with the machine.
• The work piece must be secured if it is not heavy enough to prevent
movement.
• The tool is designed for cutting on horizontal surfaces.

AIR PRESSURE AND VOLUME
The recommended air pressure for this stone cutter is 90 PSI. The most
important factor in running this stone cutter is the volume of air being sup-
plied to the stone cutter. The volume is the air consumption needed to run
this stone cutter at a constant speed under light downward hand pressure.
The volume is measured in CFM (cubic foot per minute (ft3/min)). You need
a minimum of 32 CFM to run this tool at the 1 HP rating. Alpha® recom-
mends running the tool at the maximum ow volume of 48 CFM to get the
full 2 HP rating out of the stone cutter.
It is also very important to keep your air cool, dry, and clean, so look for
a compressor with a refrigerated dryer and high-efciency lter built-in or
purchase a separate air dryer and lter unit rated for your compressors
CFM. (See page 11 for Alpha®Filter/Regulator Manifold System)
RUST PROTECTION (A rust inhibitor oil is used to protect the tool
from rusting when not in use)
PROPER CARE AND MAINTENANCE ARE IMPORTANT FACTORS IN
PREVENTING THIS TOOL FROM RUSTING ON THE INSIDE WHEN
NOT IN USE.
At the end of each workday, place 5-6 drops of rust inhibitor oil (included
with each stone cutter) into the tool using the oil port. Depress the throttle
lever varying the speed from very low to half speed, for a minute or two.
This will allow the oil to transition into the rotor assembly and coat the
inside of the tool.
CLEANING THE ROTOR ASSEMBLY
Over time, the rotor assembly can ll up with oil sludge, vane dust residue,
and contamination and will need to be cleaned. To accomplish this remove
the mufer assembly from the tool to allow the waste to exit. You can hold a
paper towel over the exit port to reduce the sound level and catch the exit-
ing waste. Add 10 to 20 drops of oil to the oil port and run the tool varying
the speed from very slow to half speed for two to three minutes to allow the
oil to process through the machine. Check the paper towel for exit waste,
continue until there is little to no exit waste.
Run the tool at its slowest speed. If the tool sounds like it is running with
a variation in speed, this is an indication that one of the vanes is still stick-
ing in the rotor. Repeat the process to see if this will correct the variation
in sound. If the problem continues, contact an authorized Alpha®Repair
Center for routine repair and maintenance.

HOW TO ADD THE RUST INHIBITOR OIL
1. Disconnect the stone cutter from your air supply.
2. Remove the screw (Part No.
3001-0061) using the supplied Hex
Wrench (5mm). (See Fig. 1)
3. Add 5-6 drops of the Rust Inhibitor
Oil into the oil port. (See Fig. 2)
4. Reinstall the Oil screw (Part
No.3001-0061).
5. Reconnect the pneumatic stone
cutter to your air supply.
6. Depress the throttle lever (Part No.
3001-0071) varying the speed from
very low to half speed, for a minute
or two. (See Fig. 3)
Replacement Rust Inhibitor Oil can be purchased from Alpha® Professional
Tools (Part No. AIR-008).
