OPERATION
Correct cut-off wheel mounting is necessary to prevent injury from
broken wheels . Do not use chipped or cracked cut-off wheels .
Cut-off wheels should be a free fit on the spindle to prevent stress at the
hole . Use only wheel collars that come with the tool for mounting the
cut-off wheel . Flat washers or other adapters may over stress the wheel .
Tighten the wheel on the spindle to prevent spin off when the tool is
turned off .
When using the cut-off tool, be careful not to exert excessive force .
Too much force could be hazardous if it causes the tool spindle to bend
or break . The burning of the work piece or excessive speed reduction
indicates too much force being applied . Start the tool off the work, set it
down on the work evenly and move in the direction desired to make the
cut . When finished cutting, lift off the work before stopping the motor .
Always use the required wheel guard to prevent injury from broken
cutting parts . If a guard has withstood a wheel breakage, discontinue
its use and replace it with a new guard. It may be damaged . Position
the guard between the cut-off wheel and the operator . Use barriers to
protect others from wheel fragments and sparks .

AIR SUPPLY

Tools operate on a wide range of air pressures . It is recommended that
air pressure measures 90 psig at the tool with the trigger fully depressed
and no load applied to the tool . Higher pressure (over 90 psig; 6 .2 bar)
raises performance beyond the rated capacity of the tool, which will
shorten tool life and could cause injury .
Always use clean, dry air . Dust, corrosive fumes and/or water in the air
line will cause damage to the tool . Drain the water from air lines and
compressor prior to running tool . Clean the air inlet filter screen weekly .
The recommended hookup procedure can be viewed in the Fig . 1 .
The air inlet used for connecting air supply (FIG . 2) has standard 1/4" NPT .
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet) . Minimum hose diameter should be 3/8" I .D . and
fittings should have the same inside dimensions and be tightly secured .
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part or
accessory on this tool, or before performing any maintenance on this
tool .
Ensure an accessible emergency shut off valve has been installed in the
air supply line and make others aware of its location .

Always wear impact-resistant eye and face protection to guard against
flying debris (users & bystanders). Even small projectiles can injure
eyes and cause blindness . A cut-off wheel that breaks can cause very
serious injury . Daily measure the tool speed with a tachometer to make
sure the speed is not greater than the RPM marked on the cut-off wheel .
Never use a cut-off wheel marked with a speed lower than the tool
speed.
NOTE: Before using, test cut-off wheel by briefly running the tool at full
throttle under a barrier (such as under a heavy work table) to stop any
possible broken wheel parts .
To Assemble Cutting Wheel:
1 . Use #46 spanner to hold spindle .
2 . Use #48 hex wrench to remove #41 screw (left hand threads) .
3 . Use #47 spanner to remove #40 nut (do not remove #39 wheel
washer) .
4 . Place cutting wheel onto spindle and re-assemble .
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic action .
Reduced compressor output, excessive drain on the air line, moisture or
restrictions in air pipes or the use of hose connections of improper size
or poor conditions may reduce air supply . Grit or gum deposits in the tool
may cut power and may be corrected by cleaning the air strainer and
flushing out the tool with gum solvent oil or an equal mixture of SAE #10
and kerosene . If outside conditions are in order, disconnect tool from
hose and take tool to your nearest authorized service center .

LUBRICATION AND MAINTENANCE

Lubricate the air motor daily with high quality air tool oil If no air line oiler
is used, run 1/2 oz . of oil through the tool . The oil can be squirted into the
tool air inlet or into the hose at the nearest connection to the air supply,
then run the tool . A rust inhibitive oil is acceptable for air tools .
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation . The
exhaust port must be covered with a towel before applying air pressure
to prevent serious injury .
