Additional Safety Rules

Tool Use

DON’T FORCE TOOL

It will do the job better and safer at the rate for which it was designed.

USE THE RIGHT TOOL

Don’t force a small tool or attachment to do the job of a heavy duty tool. Don’t used tool for purpose not intended—for example, don’t use a circular saw for cutting tree limbs or logs.

SECURE WORK

Use clamps or a vise to hold work. It’s safer than using your hand and it frees both hands to operate the tool.

NEVER LEAVE TOOL RUNNING UNATTENDED

Turn power off. Don’t leave tool until it comes to a complete stop.

Tool Care

DO NOT ALTER OR MISUSE TOOL

These tools are precision built. Any alteration or modification not specified is misuse and may result in dangerous conditions.

AVOID GASEOUS AREAS

Do not operate electric tools in a gaseous or explosive atmosphere. Motors in these tools normally spark, and may result in a dangerous condition.

MAINTAIN TOOLS WITH CARE

Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean and free from oil and grease.

! Before connecting the tool to a power source (receptacle, outlet, etc.), be sure voltageWARNINGsupplied is the same as that specified on the nameplate of the tool. A power source with a voltage greater than that specified for the tool can result in serious injury to the user, as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with a voltage less than the nameplate

rating is harmful to the motor.

STABILITY OF THE BENCH GRINDER

If there is any tendency of the bench grinder to tilt or

move during any use, bolt it to the bench top or to a

piece of 3/4" exterior plywood large enough to stabilize

the grinder. Bolt the plywood to the underside of the

base so it extends beyond the sides of the base. DO

NOT USE PRESSED WOODS PANELS. They can

break unexpectedly. If the workpiece is too large to

easily support with one hand, provide an auxiliary

support.

a.

If any part of your grinder is missing, malfunctioning,

has been damaged or broken … such as the motor

switch, or other operating control, a safety device or the

power cord … cease operating immediately until the

particular part is properly repaired or replaced.

b.

If you are not completely familiar with operating a

grinder, consult your instructor, supervisor or other qualified individual.

Additional Safety Rules

c. Only use grinding wheels with a bore exactly equal to that of the grinder arbor (shaft). Your tool is equipped with a 1/2" arbor. Never machine an undersize wheel to fit an arbor.

d. Examine grinding wheels for cracks or other damage before using grinder. Replace cracked, damaged or vibrating wheels immediately.

e. Insure that wheel flanges and blotters (paper discs on each side of the grinding wheel) are used to mount grinding wheels to the grinder shaft. Use only wheel flanges furnished with grinder. Use of other flanges may cause damage or breakage to the grinding wheel and result in injury to the operator.

f. Never operate grinder near flammable fumes or liquids. Sparks from grinding wheel or motor could ignite flammable material.

g. Do not overtighten wheel nuts.

h. Always use all guards and eyeshields, making sure they are properly adjusted and secured. Keep spark guards close to the wheel and readjust inward as the wheel wears. Always use wheel guards and covers when using a wire brush, buffing wheel or standard grinding wheel.

i. Always use grinding wheels that are rated for safe use on this grinder. Never use a wheel rated lower than 3500 R.P.M.

j. Always stop grinder before making any adjustments.

k. Do not move grinder until it comes to a full stop.

l. Do not force work against the grinding wheel. Excessive pressure may damage or break the wheel, resulting in injury to operator or bystander.

m. When turning ON the power, stand to the side of the wheel and allow the grinder to come up to speed and operate for one full minute before applying work to the wheel.

n. Never grind on the side of the wheel. Always grind on the face of the wheel only.

o. Dress the face of the wheel only. Dressing the side of the wheel may make it too thin for safe use.

p. Never apply coolant directly to the grinding wheel. Coolant may deteriorate the bonding strength of the wheel and cause it to fail.

q. Grinding creates HEAT. Never touch the workpiece until you are sure it has cooled sufficiently.

4.

11. NOTE AND FOLLOW THE SAFETY WARNINGS AND INSTRUCTIONS THAT APPEAR ON THE GRINDER:

12.THINK SAFETY

SAFETY IS A COMBINATION OF OPERATOR COMMON SENSE AND ALERTNESS AT ALL TIMES WHEN THE GRINDER IS BEING USED.

Do not allow familiarity (gained from frequent use of your grinder) to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury.

The operation of any power tool can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety goggles that comply with ANSI Z87.1 (shown

on Package) beforecommencing power tool operation.

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.

Motor Specifications

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 conductor

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.

This grinder is designed to use a 3450 RPM motor. It is

wired for operation on 110-120 volts, 60 Hz. alternating

current. Before connecting the motor cord to power

source, make certain the switch is in the “OFF” position

and be sure the electric current is of the same

characteristics as stamped on the grinder nameplate.

 

 

Connection To A Power Source

This machine must be grounded while in use to protect

the operator from electric shock.

Plug power cord into a 110-120V properly grounded type

outlet protected by a 15-amp dual element time delay fuse

or circuit breaker.

Not all outlets are properly grounded. If you are not sure

that your outlet, as pictured in Fig. 1, is properly

grounded; have it checked by a qualified electrician.

 

 

 

To avoid electric shock, do not touch the

 

!

DANGER

 

metal prongs on the plug when installing

 

or removing the plug to or from the outlet.

 

 

Failure to properly ground this power tool

!

DANGER

 

 

 

can cause electrocution or serious

shock, particularly when used near metal plumbing or

other metal objects. If shocked, your reaction could

cause your hands to hit the tool.,

!

WARNING

If power cord is worn, cut or damaged in

any way, have it replaced immediately to

avoid shock or fire hazard.

Your unit is for use on 120 volts; it has a plug that looks like the one in Figure 1.

FIG. 1

This power tool is equipped with a 3-conductor cord and grounding type plug, approved by Underwriters Laboratories and the Canadian Standards Association. The ground conductor has a green jacket and is attached to the tool housing at one end and to the ground prong in the attachment plug at the other end.

If the outlet you are planning to use for this power tool is of the two-prong type, DO NOT REMOVE OR ALTER THE GROUNDING PRONG IN ANY MANNER. Have a qualified electrician replace the TWO-prong outlet with a properly grounded THREE-prong outlet.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipmentconductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding 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.

Always use proper extension cord. The use of any extension cord will cause some loss of power. To keep this to a minimum and to prevent overheating and motor burn-out, use the table below to determine the minimum wire size (A.W.G.) extension cord. Use only 3-wire extension cords which have 3-prong grounding type plugs and 3-pole receptacles which accept the tool’s plug. Make sure your extension cord is in good condition.

Assembly and adjustments

Mounting Bench Grinder to Workbench

If bench grinder is to be used in a permanent location, it should be fastened securely to a firm supporting surface such as a stand or workbench using the two mounting holes (1), one of which is shown in figure 6. When mounting grinder to a workbench, holes should be drilled through the supporting surface of the workbench using the dimensions illustrated (Fig. 6).

1.Each of the two mounting holes should be bolted securely using 5/16" hex nuts (not included). Screw lengths should be 1-1/2" longer than the thickness of the bench top.

2.Locate and mark where the grinder is to be mounted.

3.Drill two (2) 7/16" diameter holes through workbench.

4.Place bench grinder on workbench aligning holes in base with holes drilled in workbench.

5.Insert two (2) 5/16" screws and tighten.

Mounting to Plywood

An alternative method of securing your bench grinder is to fasten the grinder base to a mounting board 12" x 18" minimum size to prevent grinder from tipping while in use. Any good grade of plywood with a 3/4" minimum thickness is recommended (Fig. 7).

1.Follow instructions for mounting to workbench, substituting a plywood board 12" x 18" minimum size and using 5/16" flat head screws, lockwashers and hex nuts (not included). Screw length must be at least 1-1/2" more than the thickness of the mounting board.

NOTE: For proper stability, holes must be countersunk so screw heads are flush with the bottom surface of the supporting board.

2.Securely clamp board to workbench using two or more “C” clamps (Fig. 7).

Supporting surface where grinder is to be mounted should be examined carefully after mounting to insure that no movement can occur during use. If any tipping or walking is noted, secure the workbench or stand before operating the bench grinder.

Operation

! Risk of injury due to accidental starting. Do not use in an area where

childrenWARNINGmay be present.

IMPORTANT: Prior to using the grinder, check that the eye shields, spark deflectors, and tool rests are fitted and correctly adjusted and that you are wearing safety gear including eye, hearing and breathing protection.

1. Turn the wheel by hand to make sure it does not touch the guard, eye shields, spark deflectors or tool rests and runs freely.

2. Stand to one side, turn the switch on and allow the motor to reach full speed.

To start grinder: push the right hand side of the switch. To turn the grinder off, push the left hand side of the switch. The “ON” and “OFF” positions are stamped on the switch plate (Fig. 8). If the grinder does not immediately start, switch the grinder “OFF”, disconnect the power cord and check voltage at power source.

! To reduce the risk of injury, no adjustments to tool rests, spark shieldsWARNINGor other components should be made

while the grinder wheels are turning.

3. Support the workpiece on the tool rest and gradually feed the workpiece onto the wheel. Use pliers to hold small workpieces.

Note. Traverse the workpiece across the full width of the wheel to prolong its flat surface.

4. If the grinding operation causes the motor speed to noticeably decrease, pull back the workpiece, allow the motor to regain full speed and restart the grinding operation, but apply less force.

! WARNING To reduce the risk of injury, only use

 

the front face of the grinding wheel,

 

 

not the sides. Note that the workpiece can get

very warm. It may be necessary to cool a

workpiece by dipping it in a coolant or in water.

Do not apply coolant or water to the grinding

wheel.

LED Light

 

Your tool is equipped with LED lights for better

visibility in the work area during operation. When the

tool is turned on, the light will turn on automatically

and stays on until the tool is turned off.

How to true and dress the wheels

Dressing a wheel cleans and levels the front surface

to increase efficiency of operation and prevent

vibration.

 

FIG. 8

1. Dressing a wheel involves the use of a wheel dresser which is not supplied with the grinder. Follow the manufacturers instructions of the wheel dresser.

2. Adjust the tool rest to allow the front part of the wheel dresser to fit between the tool rest and wheel.

3. Start the motor and move the dresser across the front of the wheel a sufficient number of times until the surface is level. It is not necessary to apply excessive force in an attempt to dress the wheel in one pass of the wheel dresser.

4. Adjust the tool rest so that it is no more than 1.5mm from the wheel.

5. Adjust the spark deflector to ensure the gap between the deflector and wheel is less than 6mm.

Grinder adjustments

During the life of the grinder some adjustments are required to maintain a safe working environment. Please ensure the following:

• Always adjust the eye shields to the most comfortable and most effective angle to suit the task being performed.

• As the wheels wear, the spark deflector must be adjusted to ensure the gap between the spark deflector and wheel does not exceed 6mm.

• As the wheels wear the tool rests must also be adjusted so there in never a gap of greater than 1.5mm between the wheel and the edge of the tool rest.
