EXPOSURE TO

VIBRATION

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.

FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY.

THIS INSTRUCTION MANUAL CONTAINS

IMPORTANT SAFETY INFORMATION.

READ THIS INSTRUCTION MANUAL CAREFULLY

AND UNDERSTAND ALL INFORMATION

BEFORE OPERATING THIS TOOL.

• Always operate, inspect and maintain this tool

in accordance with American National

Standards Institute Safety Code of Portable Air

Tools (ANSI B186.1) and any other applicable

safety codes and regulations.

• For safety, top performance and maximum

durability of parts, operate this tool at 90 psig/

6.2 bar max air pressure with 3/8" diameter

air supply hose.

• Always wear impact-resistant eye and face

protection when operating or performing

maintenance on this tool. Always wear hearing

protection when using this tool.

• High sound levels can cause permanent hearing

loss. Use hearing protection as recommended

by your employer or OSHA regulation.

• Keep the tool in efficient operating condition.

• Operators and maintenance personnel must be

physically able to handle the bulk, weight and

power of this tool.

• Air under pressure can cause severe injury.

Never direct air at yourself or others. Always

turn off the air supply, drain hose of air

pressure and detach tool from air supply before

installing, removing or adjusting any accessory

on this tool, or before performing any

maintenance on this tool. Failure to do so could

result in injury. Whip hoses can cause serious

injury. Always check for damaged, frayed or

loose hoses and fittings, and replace

immediately. Do not use quick detach

couplings at tool. See instructions for correct

set-up.

• Air powered tools can vibrate in use. Vibration,

repetitive motions or uncomfortable positions

over extended periods of time may be harmful

to your hands and arms. Discontinue use of tool

if discomfort, tingling feeling or pain occurs.

Seek medical advice before resuming use.

• Place the tool on the work before starting the tool.

• Slipping, tripping and/or falling while

operating air tools can be a major cause of

serious injury or death. Be aware of excess

hose left on the walking or work surface.

• Keep body working stance balanced and firm.

Do not overreach when operating the tool.

• Anticipate and be alert for sudden changes in

motion during start up and operation of any

power tool.

• Do not carry tool by the hose. Protect the hose

from sharp objects and heat.

• Tool shaft may continue to rotate briefly after

throttle is released. Avoid direct contact with

accessories during and after use. Gloves will

reduce the risk of cuts or burns.

• Keep away from rotating end of tool. Do not

wear jewelry or loose clothing. Secure long

hair. Scalping can occur if hair is not kept away

from tool and accessories. Choking can occur if

neckwear is not kept away from tool and

accessories.

• Correct grinding wheel mounting is necessary

to prevent injury from broken wheels. Do not

use chipped or cracked grinding wheels.

Grinding wheels should be a free fit on the

spindle to prevent stress at the hole. Use only

wheel collars that come with the grinder for

mounting the grinding wheel. Flat washers or

other adapters may over stress the wheel.

Always use heavy paper blotter discs between

the wheel collars and the grinding wheel.

Tighten the wheel on the spindle to prevent spin

off when the air grinder is turned off.

• Do not lubricate tools with flammable or volatile

liquids such as kerosene, diesel or jet fuel.

• Do not force tool beyond its rated capacity.

• Do not remove any labels. Replace any

damaged labels.

Air Supply...

Tools of this class operate on a wide range of air

pressures. It is recommended that air pressure of these

tools measures 90 PSI at the tool while running free.

Higher pressure (over 90 psig; 6.2 bar) raises

performance beyond the rated capacity of the tool which

will shorten tool life because of faster wear 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 air tank daily. Clean the air inlet filter screen on at

least a weekly schedule. 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.

Operation...

When using the grinder, be careful not to exert excessive force. Too much force may be hazardous if it causes the cutting tool

spindle to bend or break.

The burning of the work piece or excessive speed reduction indicates too much force being applied. Changing to a free cutting

tool may be better for the desired rate of speed and stock removal.

Avoid hazardous condition by making sure there is sufficient gripping force on the spindle of the cutting tool by placing the

spindle 7/16" or more inside the collet.

Lubrication...

Lubricate the air motor daily with quality air tool oil. If no air line oiler is used, run a teaspoon 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. The

amount of oil to be used is 1 ounce. Overfilling will cause a reduction in the power of the tool.

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 condition 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 oil and kerosene. If outside conditions are in order and the tool

continues erratic action at low power, disconnect tool from hose and take tool to your nearest authorized service center.
