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).

CAUTION!
Lubricating the stone cutter before and during work is not needed. Exces-
sive oil will turn to a tar-like substance inside the tool, causing the vanes
to stick in the rotor and slow the tool down. This is the reason we do not
recommend automatic oilers to be used with this stone cutter. Old or worn
compressors, which emit oil through the air lines, can signicantly shorten
the life of the tool.
HELPFUL HINT:
• Air throttle lever should be pressed and released slowly to
allow the stone cutter to accelerate and decelerate during all
applications. Rapid acceleration and deceleration can wear
out the ball bearings prematurely.
HELPFUL HINT:
• Using a Filter Regulator System i s
Recommended
FILTER/REGULATOR SYSTEM
Having a Filter/Regulator (See Fig. 4)
helps prevent pressure drops when
using a large volume of air, so you
can set the pressure to the tools at 85
to 90 PSI, while the main system can
run at 125 PSI. The F/R unit will also
remove any water from the air supply while
also ltering the air of contamination down to ve microns. By only using
aluminum and brass after the F/R unit, you are eliminating any rust and
contamination from getting into the air tools.
Alpha® recommends the F/R Manifold 106 CFM for use with the PSC-150
stone cutter. (Part Nos. 1030-0023/1030-0024). All F/R manifolds are
available through our distributor network, and via our website.

WATER CONTROL VALVE
This valve lets you adjust the ow of water to the blade. When storing the
stone cutter overnight, open the valve and drain all water from the supply
hose and tool.
AIR SUPPLY HOSE ASSEMBLY
The new 1/2” x 15’ exible air hose has a 3/8” Male NPT threaded tting
to connect to your air supply. This hose is composed of a premium hybrid
polymer that allows the hose to avoid kinking and remains exible down
to -40°F.
WATER SUPPLY HOSE ASSEMBLY
The new 1/4” x 15’ exible water hose has a 3/4”-11 GHT (Garden Hose
Thread) tting to connect to your water supply. This hose is composed of a
premium hybrid polymer that allows the hose to avoid kinking and remains
exible down to -40°F.
ARBOR SIZE
The Alpha® PSC-150 Pneumatic Stone Cutter features 7/8” / 22mm arbor
anges.
Maintenance and Usage Tip:
• Do not leave the stone cutter submersed in water. This could
expose the inner moving parts to moisture, which will shorten
the life of the stone cutter.
• Excessive force or impact to the spindle may result in
premature failure of gears and/or bearings, which may not be
immediately evident.
SOUND LEVEL (HEARING PROTECTION MUST BE WORN)
To comply with OSHA Occupational Noise Exposure Standard Number
1926.52, this tool is equipped with an internal Silencer System. When the
tool is operated correctly at 90 PSI, the sound level emitted should be less
than 91.3 dBA. The internal Silencer System is also used to maintain a
constant back pressure inside the tool; this helps prevent it from exceeding
the recommended 8,500 RPM. The exhaust deector for this stone cutter
also helps to reduce the noise level by venting the exhaust air.
