WARNING

Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities contains chemicals known to cause

cancer, birth defects or other reproductive harm. Some examples of

these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and 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 to these chemicals:

work in a well ventilated area, and work with approved safety

equipment, such as those dust masks that are specially designed

to filter out microscopic particles.

AIR SUPPLY

Tools operate on a wide range of air pressures. It is recommended

that air pressure of these tools measures 90 psig at the tool with

trigger fully depressed and no load applied to 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.

Alwaysuseclean,dryair.Dust,corrosivefumesand/orwaterintheairline

willcausedamageto thetool.Drainwaterfromairlinesandcompressor

prior to running tool. Clean the air inlet filter screen weekly. The

recommended hookup procedure can be viewed in the above figure.

The air inlet used for connecting air supply 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. Ensure an accessible emergency shut off valve has been

installed in the air supply line and make others aware of its location.

Ensure an accessible emergency shut off valve has been installed in

the air supply line and make others aware of its location.

LUBRICATION

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.

OPERATION

After mounting sandpaper, start this sander under a bench in order

to make sure sandpaper is firmly attached. After making sure the

sandpaper is secure and operating properly, set it down on the work

evenly and move it slowly back and forth in wide, overlapping areas.

When finished sanding, lift sander off the work before stopping the

motor.

NOTE: During operation, safety goggles should always be worn to

guard against flying debris (users and bystanders).

NOTE: Always shut off air supply, drain hose of air pressure

and disconnect tool from air supply when not in use, before

changing accessories or when making repairs.

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.
