BENCH GRINDER SAFETY

1. This bench grinder is designed for sharpening and 

honing cutting tools, using the appropriate accessories. 

Using the machine for any other purpose for which it 

is not designed may result in serious injuries, machine 

damage and voiding of the warranty.

2. Grinding wheel safety:

•  Only use grinding wheels rated for a speed higher 

than 3450 RPM (maximum RPM of the tool).

•  Inspect wheels for cracks or fragments before start-

ing the machine. Replace damaged wheels imme-

diately. Never use a questionable grinding wheel, 

as the RPM of the machine can send broken wheel 

fragments flying at high speeds.

•  Do not use a wheel that vibrates. If a wheel vibrates, 

it may be that the bearings of the shaft need replac-

ing.

•  Check that the grinding stone can rotate smoothly 

before starting the machine.

•  The grinding wheel is for grinding. Never attempt to 

cut anything with the grinding wheel.

3. The use of accessories or attachments not recom-

mended by the manufacturer may result in a risk of per-

sonal injury.

4. DANGER: fire hazard. Do not grind or polish magne-

sium or magnesium alloys.

5. Preventing accidental starting. Make sure the power 

switch is in the OFF position prior to plugging in the 

machine. Always make sure the power switch is in the 

OFF position and the machine is unplugged when doing 

any cleaning, adjustments, assembly, setup operations, 

or when not in use.

PERSONAL SAFETY

1. Operate in a well ventilated area. Keep the floor area 

around the bench grinder level and free of slippery sub-

stances or other tripping hazards.

2. Wear ANSI-approved safety goggles to protect your 

eyes from sparks and chips. Use hearing protection to 

protect yourself from hearing loss.

3. DO NOT wear loose clothing or jewelry as they might 

get drawn in by the tool. Tie back long hair.

4. People with pacemakers should consult their 

physician(s) before use. Electromagnetic fields in close 

proximity to pacemakers could cause pacemaker inter-

ference or pacemaker failure.

5. Chips are harmful to your health. Use NIOSH-ap-

proved  dust masks or other respiratory protection dur-

ing operation and cleaning.

6. Always turn off and unplug the bench grinder before 

making any adjustments or repair tasks. Never adjust 

the bench grinder or the workpiece while the tool is run-

ning.

PREPARING THE BENCH GRINDER

When transporting the bench grinder, carry it by the 

base. Never carry the device by its guards or its acces-

sories. 

1. Examine the bench grinder for any damaged or miss-

ing parts. Replace or repair damaged parts before op-

eration. Periodically check that all nuts, bolts and other 

fasteners are properly tightened.

2. Do not operate this tool until it is completely assem-

bled and installed according to the instructions. Make 

sure all adjustments are correct and all connections are 

tight. Keep all guards in place.

DURING OPERATION

1. Never start the machine with any load already applied 

to either grinding wheel. Stand to the side of the bench 

grinder during start-up. Switch it ON and let the bench 

grinder reach full speed for roughly one minute to warm 

up the wheel and to ensure proper operation.

2. Never grind on a cold wheel. Run the bench grinder 

for one full minute before applying the workpiece. Cold 

wheels have an increased likelihood of chipping during 

operation.
