Description

Dayton Bench Grinders are equipped with a totally enclosed ball bearing motor.

Armature assembly is dynamically balanced for smooth operation. Motor housing

is compact so long pieces of work can press against both wheels without touching

the motor frame. Removable wheel guards allow for easy changing of wheels. Tool

rests are adjustable for wheel wear and angle grinding. Grinders come complete

with spark guards, safety eyeshields and dust collection hose.

Unpacking

Check for shipping damage. If damage

has occurred, a claim must be filed with

the carrier immediately. Check for com-

pleteness. Immediately report missing

parts to dealer.

General Safety Information

For your own safety,

read operating

instructions manual before operating

tool.

Some dust created

by power sanding,

sawing, grinding, drilling and other con -

struction activities contains chemicals

known to cause cancer, birth defects or

other reproductive harm.

Some examples of these chemicals are:

1. Lead from lead-based paints.

2. Crystalline silica from bricks and

cement and other masonry products.

3. Arsenic and chromium from

chemically-treated lumber.

Your risk from these exposures vary,

depending on how often you do this

type of work. To reduce your exposure

to these chemicals: work in a well venti -

lated area and work with approved

safety equipment. Always wear

OSHA/NIOSH approved, properly fit-

ting face mask or respirator when using

such tools.

BE PREPARED FOR JOB

1. Wear proper apparel. Do not wear

loose clothing, gloves, neckties, rings,

bracelets or other jewelry which may

get caught in moving parts of machine.

2. Wear protective hair covering to

contain long hair.

3. Wear safety shoes with non-slip soles.

4. Wear safety glasses complying with

United States ANSI Z87.1. Everyday

glasses have only impact resistant

lenses. They are NOT safety glasses.

5. Wear face mask or dust mask if

operation is dusty.

6. Be alert and think clearly. Never

operate power tools when tired,

intoxicated or when taking

medications that cause drowsiness.

PREPARE WORK AREA FOR JOB

1. Keep work area clean. Cluttered work

areas and work benches invite accidents.

2. Do not use power tools in dangerous

environments. Do not use power

tools in damp or wet locations. Do

not expose power tools to rain.

3. Work area should be properly lighted.

4. Proper electrical plug should be

plugged directly into properly

grounded, three-prong receptacle.

5. Extension cords should have a

grounding prong and the three wires

of the extension cord should be of

the correct gauge.

6. Keep visitors at a safe distance from

work area.

7. Keep children out of the workplace.

Make workshop childproof. Use

padlocks, master switches or remove

switch keys to prevent any uninten-

tional use of power tools.

TOOL SHOULD BE MAINTAINED

1. Always unplug tool prior to inspection.

2. Consult manual for specific maintain-

ing and adjusting procedures.

3. Keep tool clean for safest operation.

4. Remove adjusting tools. Form habit

of checking to see that adjusting

tools are removed before turning

machine on.

5. Keep all parts in working order.

Check to determine that the guard or

other parts will operate properly and

perform their intended function.

6. Check for damaged parts. Check for

alignment of moving parts, binding

of moving parts, breakage of parts,

mounting and any other condition

that may affect a tool’s operation.

7. A guard or other part that is damaged

should be properly repaired oraced.

Do not perform makeshift repairs.

(Use the parts list to order repair

parts.)
