SECTION 1: SAFETY

For Your Own Safety, Read Instruction

Manual Before Operating this Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions. This

manual uses a series of symbols and signal words which are intended to convey the level of

importance of the safety messages. The progression of symbols is described below. Remember

that safety messages by themselves do not eliminate danger and are not a substitute for proper

accident prevention measures.

Indicates an imminently hazardous situation which, if not avoided,

WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

MAY result in minor or moderate injury. It may also be used to alert

against unsafe practices.

This symbol is used to alert the user to useful information about

proper operation of the machine.

Additional Safety Instructions for Grinders

1. EYE PROTECTION. Grinding ejects small

particles at a high rate of speed. ALWAYS

wear safety glasses when using this

machine.

7. LUNG PROTECTION. Grinding produces

hazardous dust, which may cause long-

term respiratory problems. Always wear a

NIOSH–approved dust mask or respirator

when grinding.

2. MOUNTING TO BENCH/STAND. An unse-

cured grinder may become dangerously

out of control during operation. Make sure

grinder is FIRMLY secured to a bench/

stand before use.

8. SIDE GRINDING. Grinding on the side of

wheels can cause the them to break and

fly apart—unless the wheel is rated for side

grinding.

3. WHEEL SPEED RATING. Wheels oper-

ated at a faster speed than rated for

may break or fly apart. Before mount-

ing a new wheel, be sure the wheel

RPM rating is equal or higher than the

speed of the grinder.

9. TOP GRINDING. Grinding on the top

of wheels greatly increases the risk of

workpiece kickback. Always grind on the

downward part of the wheel.

10. HAND/WHEEL CONTACT. Grinding

wheels can remove a lot of skin fast. Keep

a firm grip on the workpiece and position

your hands a safe distance away when

grinding. DO NOT wear gloves as they

may get caught in the grinding wheel and

cause even more serious injuries.

4. WHEEL FLANGES. Only use the flanges

included with the grinder when mounting

wheels. Other flanges may not properly

secure the wheel and cause an accident.

5. RING TEST. Perform a "ring test" on grind-

ing wheels before installation to ensure

that they are safe to use. A wheel that does

not pass the ring test may break or fly apart

during operation.

11. TOOL REST POSITION. If the tool rest is

too far away from the wheel, the workpiece

may be pulled down, causing loss of con-

trol and pulling your hand into the grinding

wheel. Keep the tool rest within ¹⁄8" from the

wheel when operating.

6. STARTING GRINDER. If a wheel is dam-

aged, it will usually fly apart shortly after

start-up. To protect yourself, always stand

to the side of the grinder when turning it

ON and allow it to run a full minute before

standing in front of it.

12. CRACKED WHEEL. Cracked wheels

may break and fly apart during operation.

Replace cracked wheels immediately!

No list of safety guidelines can be complete.

Every shop environment is different. Always

consider safety first, as it applies to your

individual working conditions. Use this and

other machinery with caution and respect.

Failure to do so could result in serious per-

sonal injury, damage to equipment, or poor

work results.

Like all machinery there is potential danger

when operating this machine. Accidents are

frequently caused by lack of familiarity or

failure to pay attention. Use this machine

with respect and caution to lessen the pos-

sibility of operator injury. If normal safety

precautions are overlooked or ignored, seri-

ous personal injury may occur.

SECTION 2: CIRCUIT REQUIREMENTS

Plug Type

Operation

With the exception of the G0596, the cord set

enclosed does not have a plug as the style of plug

you require will depend upon the type of service

you currently have or plan to install. We recom-

mend using the following plugs for your machine

on a dedicated circuit only (see Figures 1–3 for

examples):

Serious personal injury could occur if you

connect the machine to the power source

before you have completed the set up pro-

cess. DO NOT connect the machine to the

G0598 at 220V Single-Phase............... 12 Amps

G0599 at 220V 3-Phase....................... 10 Amps

Circuit Requirements

We recommend connecting this machine to a

dedicated circuit with a verified ground, using the

circuit breaker size given below. Never replace a

circuit breaker with one of higher amperage with-

out consulting a qualiﬁed electrician to ensure

compliance with wiring codes. If you are unsure

about the wiring codes in your area or you

plan to connect your machine to a shared cir-

cuit, you may create a fire hazard—consult a

qualified electrician to reduce this risk.

Grounding

In the event of an electrical short, grounding

reduces the risk of electric shock. The grounding

wire in the power cord must be properly connect-

ed to the grounding prong on the plug; likewise,

the outlet must be properly installed and ground-

ed. All electrical connections must be made in

accordance with local codes and ordinances.

Extension Cords

Figure 3. A locking shut-off switch near the

machine.

We do not recommend the use of extension

cords. Instead, arrange the placement of your

equipment and the installed wiring to eliminate

the need for extension cords.

If you find it absolutely necessary to use an exten-

sion cord with your machine, the extension cord

must also contain a ground wire and plug pin.

110V Operation

Use at least a 12 gauge cord that does not exceed

50 feet in length!

220V Operation

Use at least a 12 gauge cord that does not exceed

50 feet in length!

This machine must have a ground prong in

the plug to help ensure that it is grounded.

DO NOT remove ground prong from plug

to fit into a two-pronged outlet! If the plug

will not fit the outlet, have the proper outlet

installed by a qualified electrician.

Phase Converter

When using a phase converter for 3-phase, the

power from the manufactured power leg (some-

times called the wild wire) can fluctuate. Connect

the manufactured power leg to the S terminal to

prevent damage. The wire from the S terminal can

handle some fluctuation because it goes directly

to the motor. The power going to the R and T

terminals goes to the transformer and must be

consistent to prevent damage.

The test run ensures that the grinder and grinder

wheels were not damaged during shipping.

DO NOT operate the Model G0596/G0597/

G0598/G0599 without an adequate dust col-

lection system. This grinder creates substan-

tial amounts of dust while operating. Failure

to use a dust collection system can result in

short and long-term respiratory illness.

To test run the grinder:

1. Review and understand all grinder safety

information.

2. Remove the wheels and closely inspect the

overall conditions. Follow this by performing

a "Ring Test" (see Wheel Inspection on

Page 15 and Wheel Replacement on Page

16).

The Model G0596/G0597/G0598/G0599 features

a dust port at the rear of the grinding wheel. If a

dust collection system is not attached, both ports

have spark deflectors that direct sparks down-

ward.

3. Plug the grinder into the power source.

4. Put on safety glasses and face shield.

To connect a dust collection hose:

5. Stand to the side of the line of the wheels

rotation, turn the grinder ON, and allow it to

run a least one minute, before standing in

front of it.

1. Remove the spark deflector.

2. Fit the dust hose over the dust port, as

shown in Figure 5, and secure in place with

a hose clamp.

—The grinder should run smoothly.

3. Tug the hose to make sure it does not come

off. Note: A tight fit is necessary for proper

performance.

—Grinding wheels should run true without

noticeable vibration.

—If there is an obvious problem with the way

the grinder is running, turn it OFF immedi-

ately and troubleshoot the problem, using

the troubleshooting table on Page 18. DO

NOT operate the grinder until it is fixed.

SECTION 4: OPERATIONS

Operation Safety

Grinding Tips

The grinder is a safe tool when used properly. In

addition to the safety instructions in this manual,

the most important safety consideration is to use

common sense at all times. What may be okay in

one situation, may not be safe in another.

Damage to your eyes, lungs, and ears could

result from using this machine without prop-

er protective gear. Always wear safety glass-

es with face shield, a respirator, and hearing

protection when operating this machine.

Here are some tips to keep in mind while

grinding:

•

DO NOT grind on the side of the wheel.

The wheels provided with the Model G0596/

G05967/G0598/G0599 are not designed for

side grinding. Grinding on the side greatly

stresses the wheel and may cause it to shat-

ter.

•

Wear the proper protective clothing. Particles

flying off of a grinding wheel will be travel-

ing very fast—prepare for this. Wear safety

glasses/face shield, a dust mask, earplugs,

a leather apron, and heavy leather boots.

Loose hair and cloth-

ing could get caught in

machinery and cause seri-

ous personal injury. Keep

loose clothing and long

hair away from moving

machinery.

•

Make sure all guards are in place.

Remember that grinding often produces

sparks. DO NOT allow anyone to stand in

the path of the sparks. DO NOT grind near

flammable materials.

NOTICE

If you have never used this type of machine

or equipment before, WE STRONGLY REC-

OMMEND that you read books, trade maga-

zines, or get formal training before begin-

ning any projects. Regardless of the con-

tent in this section, Grizzly Industrial will

not be held liable for accidents caused by

lack of training.

•

Maintain proper care of your wheels. Read

the Wheel Care on Page 14.

Grasp the workpiece firmly and properly

support it on the tool rest during grinding.

Maintain even pressure and control of the

workpiece when grinding.

•

Concentrate on the task at hand. STOP

grinding if you are distracted.

DO NOT grind workpieces that are heavier

than the wheel itself. This stresses the

wheel. In these cases use a handheld grind-

er instead.

Wheel Care

Wheel Selection

Your safety when grinding depends, on a large

part, on the condition of the wheel during grind-

ing. A wheel in poor condition presents the possi-

bility of breaking apart during rotation and injuring

the operator and others in the area.

The Model G0596/G0597 only accepts Type 1

wheels with a 1" bore. The Model G0598/G0599

only accepts Type 1 wheels with a 1¹⁄4" bore.

Aluminum oxide and silicon carbide wheels are

marked in a somewhat uniform manner by all the

major manufacturers. Understanding these mark-

ings will help you understand the capabilities of

various wheels. Always refer to the manufactur-

er’s grinding recommendations when selecting a

wheel for your project.

Here are some tips to help you avoid breaking

the wheel:

•

Always transport, store and handle wheels

with care. Wheels may be damaged if they

are dropped or if heavy objects are stacked

on them.

The basic format for wheel numbering is:

Abrasive

Type

Bond

Type

•

Select the right grinding wheel for the job.

DO NOT grind material inappropriate for the

wheel type.

Prefix

Grit Size Grade

Select the right wheel for the machine. A

machine that rotates at a higher RPM than

the wheel is rated for may cause the wheel

to fly apart.

The Prefix is the manufacturer’s designation for a

particular wheel type (eg, Type 1 wheels).

The most common Abrasive Types used are A

for Aluminum Oxide, C for Silicon Carbide, and

occasionally SG for Seeded Gel.

•

Mount the wheels properly. (See the Wheel

Replacement instructions on Page 16 for

guidance.)

The Grit Size is a number that refers to the size

of the abrasive grain in the wheel. The lower the

number, the coarser the wheel. Ten is a very

coarse wheel for roughing and 220 is usually the

upper range for fine finish work.

Do not abuse the wheel by jamming the work

into the grinding wheel with excessive force

that causes the grinder to bog down, or apply

pressure to stop the wheel after turning the

grinder OFF.

Grade is an indication of the hardness of the

wheel—“A” being the softest and “Z” being the

hardest.

•

Dress the wheel when necessary. Do not

allow it to become glazed.

Always spin water/coolant out of the wheel

before turning the grinder OFF. This may

take 5–10 minutes. (If moisture is left on the

wheel, the wheel may warp.)

Bond Type refers to the type of bonding material

used to hold the abrasive material. Most general

purpose wheels will have a “V” indicating Vitrified

Clay is used. Vitrified Clay provides high strength

and good porosity. The other common bond type

is “B” for resin where synthetic resins are used.

These are used to grind cemented carbide and

ceramic materials.

•

Do not store wheels in damp or wet loca-

tions.

Do not grind on the side of the wheel unless

wheel is designed for side grinding.

Note: There may be other numbers inserted that

have meaning for a particular type of wheel. Refer

to the manufacturer’s technical data for a com-

plete explanation.

Do not overtighten the nut when mounting

the wheel.

4. An undamaged wheel will emit a clear metal-

lic ring or “ping” sound in each of these spots.

A damaged wheel will respond with a dull

thud that has no clear tone.

Wheel Inspection

Before mounting a new grinding wheel, it must

be inspected. Do not assume that a wheel is in

sound condition just because it is new—often

damage can occur in shipping, with age, or with

exposure to moisture.

5. If you determine from the ring test that the

wheel is damaged, DO NOT use it!

Wheel Dressing

First, do a Visual Inspection. Look for any

cracks, chips, nicks or dents in the surface of the

wheel. If you see any of these, DO NOT use the

wheel.

Depending on the type of grinding you do, the

grinding wheel may require periodic dressing.

Second, do a Ring Test. This test will give you an

indication of any internal damage that may not be

obvious during a visual inspection.

There are several different types of wheel dress-

ing devices available on the market (see Page

17). Dressing restores the abrasive quality of the

wheel surface and brings the wheel edge back to

a square form.

To perform a Ring Test:

1. Make sure the wheel that you test is clean and

Refer to the instructions that accompany your

dressing accessory for complete details on how

to properly dress a wheel.

dry; otherwise, you may get false results.

2. If size permits, balance the wheel with your

finger in the hole. If this is not possible, hang

the wheel in the air with a piece of cord or

string looped through the hole in the center.

3. At the spots shown in Figure 6, gently tap

the wheel with a light non-metallic device

such as the handle of a screwdriver or a

wooden mallet.

Note: Finding the exact spot to tap will take

several attempts.

Wheel Replacement

��

ALWAYS visually inspect and perform a

“ring test” on a wheel before assembly. DO

NOT use damaged wheels!

�

The wheel guard must be removed in order to

mount or dismount a grinding wheel.

Figure 7. Assembly order for wheel installation.

To replace a grinding wheel:

1. UNPLUG THE GRINDER!

2. Remove the wheel guard.

Arbor Nut

3. Use a wrench on the arbor nut. Hold the

wheel from turning with your other hand.

Note that the wheel on the left-hand side of

the machine has left-handed threads, so the

arbor nut on that side must be turned clock-

wise to loosen.

4. Remove the outer wheel flange and the

paper disc. Pull the wheel free from the

arbor. There will also be a paper disc and a

wheel flange on the other side of the wheel.

Figure 8. Nut removal/tightnening.

6. Re-install the wheel guard.

5. Mount the new wheel as shown in Figure

7. Always make certain there is a paper or

fiber disc between the wheel flanges and

the wheel itself. Tighten the nut snugly but

DO NOT over-tighten. Over-tightening can

crack the wheel (see Figure 8).

7. Run a new wheel for at least one minute

while standing clear of the line of rotation. If

a wheel does have defects it will generally fail

within that time.

NEVER assemble a grinding wheel on the

arbor without paper or fiber discs between

the wheel and the flange. Not using the

discs can put stress on the wheel, causing

it to crack and possibly fall apart.
