SAFETY NOTICE Continued
WARNING: Never install a wheel that is damaged, such as a chip or crack on any surface. A damaged
wheel can disintegrate while rotating at a high RPM or when work is placed against the
wheel. This can severely harm the operator or others in the area.
WARNING: Check damaged parts. Before further use of the grinder, a guard or other part that is
damaged should be carefully checked to assure 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 should be properly repaired or replaced.
WARNING: Use proper extension cord. Make sure your extension cord is in good condition. When
using an extension cord, be sure it is rated for the voltage and current rating of your
product. An undersized cord will cause a drop in line voltage resulting in loss of power
and overheating. Table 1 shows the correct wire size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the AWG
gauge number, the heavier the cord.
WARNING: Dust created during grinding, sawing, power sanding, drilling, and other activities may
contain chemicals known to the State of California to cause cancer, birth defects or other
reproductive harm.
WARNING: Keep children and visitors away. Remove starter keys turn off master switches. Padlock
equipment or work area when not in use.
WARNING: Never leave grinder running unattended. Always turn power off after use.
Caution: Don’t force grinder. It will do the job better and safer at the feed rate for which it was
designed.
Caution: Use right tool. Don’t force tool or attachment to do a job for which it was not designed.
Caution: Maintain grinder with care. Keep grinder clean for best and safest performance.
Always use guard and eyeshield. Operating the grinder without the guard and eyeshield or
with damaged guard and eyeshield must not be attempted because of the hazard this
introduces.
Do not overtighten wheel nut. A damaged grinding wheel can disintegrate in all directions.
An overtightened wheel nut can stress the grinding wheel and cause it to disintegrate during
operation. Wheel nut should be tightened just enough to prevent grinding wheel from slipping
on shaft when grinding. Use only flanges furnished with this grinder. The flanges furnished
with the grinder are designed to grip the grinding wheel without introducing excessive
stresses in the wheel.
Replace a cracked or chipped wheel immediately. A cracked wheel will disintegrate when
operated, causing a hazard to operator and nearby personnel. If a wheel has a chip or crack
on any surface, do not use it.
Maintain 1/8 or less clearance between tool rest and wheel. This clearance is necessary
to prevent the work piece from becoming wedged between the wheel and tool rest and
restricting nip areas in the machine.
Grind on grinding face (periphery) of wheels only. Grinding on side of wheel weakens the
wheel and may cause wheel breakage. Also, grinding on the side of wheel introduces an
additional hazard due to absence of a tool rest.
