READ OPERATING INSTRUCTIONS

Always become familiar with all the instructions and

warnings before operating any pneumatic tool.

RECOGNIZE SAFETY INFORMATION

This is the safety alert symbol. When you see this symbol

on your pneumatic tool or in this manual, be alert to the

potential for personal injury.

Follow recommended precautions and safe operating

practices.

UNDERSTAND SIGNAL WORDS

A "DANGER, WARNING or CAUTION" safety warning will be

surrounded by a "SAFETY ALERT BOX." This box is used to

designate and emphasize Safety Warnings that must be

followed when operating this tool.

Accompanying the Safety Warnings are "signal words" which

designate the degree or level of hazard seriousness. The

"signal words" used in this manual are as follows:

DANGER: Indicates an imminently hazardous situation

which, if not avoided, WILL result in death or

serious injury.

WARNING: Indicates a potentially hazardous situation

which, if not avoided, COULD result in death or

serious injury.

CAUTION: Indicates a potentially hazardous situation

which, if not avoided MAY result in minor or

moderate injury.

ALWAYS PROVIDE A COPY OF THIS MANUAL TO

ANYONE USING THIS EQUIPMENT. READ ALL

INSTRUCTIONS BEFORE OPERATING THIS TOOL

AND ESPECIALLY POINT OUT THE "SAFETY

WARNINGS" TO PREVENT THE POSSIBILITY OF

PERSONAL INJURY TO THE OPERATOR.

Safety

4-Inch Angle Grinder Operator's Manual 5

ALWAYS WEAR APPROVED EYE PROTECTION

Impact resistant eye protection should meet or

exceed the standards as set forth in the United

States ANSI Z87.1, Occupational and Educational

Eye and Face Protection. Look for the marking

Z87.1 on your eye protection to insure that it is an

approved style. For further information, ANSI Z87.1,

Occupational and Educational Eye and Face

Protection, is available from the American National

Standards Institute, Inc., 11 West 42nd Street, New

York, NY 10036.

HEARING PROTECTION IS RECOMMENDED

Hearing protection should be used when the noise

level exposure equals or exceeds an 8 hour time-

weighted average sound level of 85 dBA. Process

noise, reflective surfaces, other tools being operated

nearby, all add to the noise level present in your

work area. If you are unable to determine your noise

level exposure, we recommend the use of hearing

protection.

WEAR RESPIRATORY PROTECTION

It is advisable, when using this tool for extended

periods of time, to wear a protective mask. This will

help prevent the inhalation of the fine dust produced

while using this tool. Prolonged breathing of dust

particles may lead to future respiratory problems.

Some dust created by power sanding, sawing,

grinding, drilling and other construction activities

contain chemicals known to cause cancer, birth

defects or reproductive harm. Some examples of

these chemicals are:

• Lead from lead-base paints

• Crystalline Silica from bricks, cement and other

masonry products.

• 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.

WARNING

6 4-Inch Angle Grinder Operator's Manual

AVOID PROLONGED EXPOSURE TO VIBRATION

Pneumatic tools can vibrate during use. Prolonged exposure

to vibration or very repetitive hand and arm movements, can

cause injury. Stop using any tool if discomfort, tingling feeling

or pain occurs. You should consult your physician before

resuming use of the tool.

90 PSIG MAXIMUM

Designed to operate at an air pressure of 90 pounds per square

inch gauge pressure (90 PSIG) maximum, at the tool. Use of

higher air pressure can, and may cause injury. Also use of

higher air pressure places the internal components under loads

and stresses they were not designed for, causing premature

tool failure.

NOTE: The air supply should be clean and dry, preferably

lubricated. For best results drain the moisture from your

compressor daily.

USE ACCESSORIES RATED AT TOOL RPM OR HIGHER

Always use grinding wheels with an RPM rating that meets or

exceeds the tool RPM rating. Always examine wheels for chips,

cracks or signs of damage before mounting. Never use grinding

wheels that have been dropped or exposed to: water, solvent or

extreme temperature changes. The grinder’s speed should be

checked with a tachometer before mounting a wheel; after all

repairs and whenever the grinder is issued for use.

WARNING

CAUTION

4-Inch Angle Grinder Operator's Manual 7

Always use clean dry air. Excessive moisture and dirt will greatly reduce the life of any

air motor. We recommend the installation of an in-line filter-regulator-lubricator as

close to the tool as possible.

A 3/8" air hose is required up to a length of 8 ft. If more length is required a 1/2" air

hose should be connected to the 3/8" hose to ensure the tool has the necessary air

supply. Be sure all hoses and fittings are the correct size and tightly secured.

RECOMMENDED AIR LINE SET-UP

Designed to operate on 90 PSIG, lower pressure (below

90 PSIG) will reduce performance of the tool while higher air

pressure (over 90 PSIG) raises the performance of the tool

beyond its rated capacity and could cause serious damage to

tool and user.

Installation

8 4-Inch Angle Grinder Operator's Manual

Maintenance

LUBRICATION:

An automatic in-line filter-regulator-lubricator is recommended as it increases tool life

and keeps the tool in sustained operation. The in-line lubricator should be regularly

checked and filled with John Deere AT-4003 air tool oil. Proper adjustment of the in-line

lubricator is performed by placing a sheet of paper next to the exhaust ports and

holding the throttle open approximately 30 seconds. The lubricator is properly set when

a light stain of oil collects on the paper. Excessive amounts of oil should be avoided.

In the event that it becomes necessary to store the tool for an extended period of time

(overnight, weekend, etc.), it should receive a generous amount of lubrication at that

time. The tool should be run for approximately 30 seconds to ensure oil has been

evenly distributed throughout the tool. The tool should be stored in a clean and dry

environment.

Recommended lubricants: Use John Deere AT-4003 air tool oil or any other high

grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents

and an EP (extreme pressure) additive.

Operation

PRE-OPERATION:

Before the tool is connected to the air supply, clear the air hose of accumulated dust

and moisture. Before removing a tool for service or changing accessories, make sure

the air line is shut-off and drained of air. This will prevent the tool from operating if the

throttle is accidentally engaged.

OPERATION:

Designed to use 4" type 27 grinding wheels only. This tool must be operated with the

guard installed on the tool to avoid serious injury. The guard should be positioned so

that the opening in the guard is away from the operator. Any wheel guard that is bent

or damaged must be replaced.

The grinder should be gradually applied to the work surface until the wheel becomes

warm. Make smooth contact with the work and avoid any bumping action or exces-

sive force.

The type 27 grinding wheel is designed to remove material with the face portion of the

wheel. Do not use edge of the wheel to cut material.

This angle grinder is supplied with a lock-off lever to prevent accidental starts. To

begin operation, grip tool and depress the safety lock with thumb then depress throttle

lever.

CAUTION: NEVER OPERATE TOOL WITHOUT GUARD

PROPERLY INSTALLED. DO NOT

OVERTIGHTEN WHEEL NUT OR WHEEL

MAY CRACK.
