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 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 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.

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

When using the Die Grinder, be careful not to exert excessive force which could be hazardous and cause mounted spindle to bend or break.

Bonded abrasive mounted point grinding wheels, rotary files and carbide burrs can be mounted providing their speed rating exceeds the speed of the Die Grinder. The shank size of the mounted accessory must match the collet size fitted in the Die Grinder. Insert the shank of the mounted point as far as possible into the collet and tighten the nut using the supplied wrenches. Minimum shank gripping length must be 10mm.

After mounting a new point, start the Die Grinder under bench and run for a few seconds. If the Die Grinder starts to vibrate when first fitting a mounted point or during operation, immediately remove from service. If Die Grinder is dropped, replace bonded abrasive mounted grinding wheel, rotary file or carbide burr.

NoTe: During operation, safety goggles must always be worn to guard against flying rust and chips (users and bystanders).

NoTe: Al ways 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.
