the tool. Safety is a combination of common sense, staying

alert, and knowing how your bench grinder works.

during extended periods of operation.

n DON’T ABUSE CORD. Never carry tool by the cord or

yank it to disconnect from receptacle. Keep cord from

heat, oil, and sharp edges.

READ ALL INSTRUCTIONS

n DO NOT OVERREACH. Keep proper footing and balance

n KNOW YOUR POWER TOOL. Read the operator's

manual carefully. Learn the applications and limitations

as well as specific potential hazards related to this tool.

n GUARD AGAINST ELECTRICAL SHOCK by prevent-

ing body contact with grounded surfaces. For example:

pipes, radiators, ranges, refrigerator enclosures.

n KEEP GUARDS IN PLACE and in working order. Never

operate the tool with any guard or cover removed. Make

sure all guards are operating properly before each use.

n REMOVE ADJUSTING KEYS AND WRENCHES. Form

habit of checking to see keys and adjusting wrenches are

removed from tool before turning it on.

at all times.

n MAINTAIN TOOLS WITH CARE. Keep tools sharp and

clean for best and safest performance. Follow instructions

for lubricating and changing accessories.

n NEVER LEAVE TOOL RUNNING UNATTENDED. TURN

POWER OFF. Disconnect all tools when not in use, before

servicing, or when changing attachments, wheels, etc.

n AVOID ACCIDENTAL STARTING. Be sure switch is off

when plugging in.

n USE RECOMMENDED ACCESSORIES. The use of

improper accessories may cause risk of injury.

n USE ONLY GRINDING WHEELS that comply with ANSI

B7.1 and rated greater than 3600 RPM.

n KEEP THE WORK AREA CLEAN. Cluttered work areas

and work benches invite accidents.

n AVOID DANGEROUS ENVIRONMENTS. Do not use

power tools near gasoline or other flammable liquids,

in damp or wet locations or expose them to rain. Keep

work area well lighted.

n DO NOT use wheels with incorrect size holes. NEVER

use wheel washers or wheel screws that are defective

or incorrect and NEVER touch grinding wheel or other

moving parts.

n KEEP CHILDREN AND VISITORS AWAY. All visitors

should wear safety glasses and be kept a safe distance

from work area.

n NEVER STAND ON TOOL. Serious injury could occur if

the tool is tipped or if the wheel is unintentionally con-

tacted.

n MAKE WORKSHOP CHILDPROOF with padlocks,

master switches, or by removing starter keys.

n DON’T FORCE THE TOOL. It will do the job better and

safer at the rate for which it was designed.

n DIRECTION OF FEED. Be aware of wheel rotation direc-

tion; never grind without the workrest being properly set.

NEVER grind more than one workpiece at a time.

n USE THE RIGHT TOOL. Do not force the tool or attach-

ment to do a job for which it was not designed.

n USE THE PROPER EXTENSION CORD. Make sure

your extension cord is in good condition. When using

an extension cord, be sure to use one heavy enough to

carry the current your product will draw. An undersized

cord will cause a drop in line voltage resulting in loss of

power and overheating. A wire gage size (A.W.G.) of at

least 16 is recommended for an extension cord 25 feet

or less in length. If in doubt, use the next heavier gage.

The smaller the gage number, the heavier the cord.

n INSPECT EXTENSION CORDS PERIODICALLY and

replace if damaged.

WARNING: Wheel coasts after turn off.

n CHECK DAMAGED PARTS. Before further use of the

tool, a guard or other part that is damaged should be

carefully checked to determine that it will operate properly

and perform its intended function. Check for alignment

of moving parts, binding of moving parts, breakage of

parts, mounting and any other conditions that may affect

its operation. A guard or other part that is damaged must

be properly repaired or replaced by an authorized service

center to avoid risk of personal injury.

n KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND

GREASE. Always use a clean cloth when cleaning. Never

use brake fluids, gasoline, petroleum-based products, or

any solvents to clean tool.

n INSPECT TOOL CORDS AND EXTENSION CORDS

PERIODICALLY and, if damaged, have repaired by a

qualified service technician. Stay constantly aware of

cord location and keep it well away from the rotating

wheel.

n NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal

sparking of the motor or sparking from grinding metal could

ignite fumes.

n WEAR PROPER APPAREL. Do not wear loose clothing,

neckties, or jewelry that can get caught in the tool’s

moving parts and cause personal injury. Nonslip footwear

is recommended when working outdoors. Wear protective

hair covering to contain long hair.

n ALWAYS WEAR SAFETY GLASSES WITH SIDE

SHIELDS. Everyday eyeglasses have only impact-

resistant lenses; they are NOT safety glasses.

n PROTECT YOUR LUNGS. Wear a face or dust mask if

the cutting operation is dusty.

from frequent use of your grinder) to cause a careless

mistake. ALWAYS REMEMBER that a careless fraction

of a second is sufficient to inflict severe injury.

n DO NOT TURN THE MOTOR SWITCH ON AND OFF

RAPIDLY. This could cause the wheel to loosen and could

create a hazard. Should this ever occur, stand clear and

allow the wheel to come to a complete stop. Disconnect

your grinder from the power supply and securely retighten

the wheel nut.

n STAY ALERT AND EXERCISE CONTROL. Watch what

you are doing and use common sense. Do not operate

tool when you are tired. Do not rush.

n SAVE THESE INSTRUCTIONS. Refer to them frequently

and use them to instruct other users. If you loan someone

this tool, loan them these instructions also.

WARNING:

When servicing use only identical Ryobi replacement

parts. Use of any other parts may create a hazard or

cause product damage.

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:

n USE ONLY FLANGES furnished with this bench

grinder.

n IF ANY PART OF THIS GRINDER IS MISSING or should

break, bend, or fail in any way, or should any electrical

component fail to perform properly, shut off the power

switch, remove the machine plug from the power source

and have damaged, missing, or failed parts replaced be-

fore resuming operation.

• lead from lead-based paints,

• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-treated

lumber.

n MAKE SURE THE GRINDER IS SECURELY MOUNTED

as described in the operating instructions before con-

necting the tool to a power supply.

n DO NOT OVERTIGHTEN THE WHEEL NUT. Excessive

tightening can cause the wheel to crack during opera-

tion.

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

masksthatarespeciallydesignedtofilteroutmicroscopic

particles.

n INSPECT GRINDING WHEEL for visible defects. Check

the wheel for fissures and cracks, and test for normal

operation prior to use.

n ADJUST distance between wheel and work rest to main-

tain 1/16 in. or less separation as the diameter of the

wheel decreases with use. The value of separation used

in the marking is to be the separation recommended by

the manufacturer but shall not be more than 1/8 in.

ELECTRICAL

EXTENSION CORDS

ELECTRICAL CONNECTION

Use only 3-wire extension cords that have 3-prong ground-

ing plugs and 3-pole receptacles that accept the tool's plug.

When using a power tool at a considerable distance from the

power source, use an extension cord heavy enough to carry

the current that the tool will draw. An undersized extension

cord will cause a drop in line voltage, resulting in a loss of

power and causing the motor to overheat. Use the chart

provided below to determine the minimum wire size required

in an extension cord. Only round jacketed cords listed by

Underwriter's Laboratories (UL) should be used.

Your Ryobi Bench Grinder is powered by a precision built

electric motor. It should be connected to a power supply

that is 120 volts, 60Hz, AC only (normal household current).

Do not operate this tool on direct current (DC). A substantial

voltage drop will cause a loss of power and the motor will

overheat. If the machine does not operate when plugged

into an outlet, double check the power supply.

CAUTION:

Keep the cord away from the grinding area and position

the cord so that it will not be caught on material, tools,

or other objects.

Length of Extension Cord

Up to 25 feet

Wire Size (A.W.G.)

26-50 feet

51-100 feet

GROUNDING INSTRUCTIONS

When working with the tool outdoors, use an extension cord

that is designed for outside use. This is indicated by the

letters WA on the cord's jacket.

In the event of a malfunction or breakdown, grounding

provides a path of least resistance for electric current to

reduce the risk of electric shock. This tool is equipped with

an electric cord having an equipment-grounding conduc-

tor and a grounding plug. The plug must be plugged into a

matching outlet that is properly installed and grounded in

accordance with all local codes and ordinances.

Before using an extension cord, inspect it for loose or

exposed wires and cut or worn insulation.

Do not modify the plug provided. If it will not fit the outlet,

have the proper outlet installed by a qualified electrician.

Improperconnectionoftheequipment-groundingconductor

can result in electrical shock. The conductor with insulation

having an outer surface that is green with or without yellow

stripes is the equipment-grounding conductor. If repair or

replacement of the electric cord or plug is necessary, do

not connect the equipment-grounding conductor to a live

terminal.

Check with a qualified electrician or service personnel if the

grounding instructions are not completely understood, or if

in doubt as to whether the tool is properly grounded.

GROUNDING

Repair or replace a damaged or worn cord immediately.
