General Safety Information
1.
For Additional Safety
Information Consult:
Your employer, union, and/or trade
association. US Department of Labor
(OSHA); www.osha.gov. “Safety Code
For Portable Air Tools” (B186.1)
2.
Wheel Guard Usage
Always use the recommended wheel
guard to prevent injury from broken
grinding wheel parts.
If a guard has withstood a wheel
breakage do not continue to use it. It may
be damaged.
Position the guard between the grinding
wheel and the operator.
Use barriers to protect others from wheel
fragments and grinding sparks.
3.
Projectile Hazards
Always wear impact-resistant eye and
face protection when involved with or
near the operation, repair or
maintenance of the tool or changing
accessories on the tool.
Be sure all others in the area are wearing
impact-resistant eye and face protection.
Even small projectiles can cause eye
injuries and blindness.
A grinding wheel that bursts can cause
very serious injury.
Daily measure the air grinder speed with
a tachometer to make sure it is not
greater than the RPM marked on the
grinding wheel.
Never use a grinding wheel marked with
a speed lower than the air grinder speed.
4.
Grinding Wheel Mounting Hazards
Correct grinding wheel mounting is
necessary to prevent injury from broken
wheels.
Do not use chipped or cracked grinding
wheels.
Grinding wheels should be a free fit on
the spindle to prevent stress at the hole.
Use only wheel collars that come with the
grinder for mounting the grinding wheel.
Flat washers or other adapters may over
stress the wheel. Always use heavy paper
blotter discs between the wheel collars
and the grinding wheel.
Tighten the wheel on the spindle to
prevent spin off when the air grinder is
turned off.
Before grinding, test grinding wheel by
briefly running tool at full throttle. Be
sure to use a barrier (such as under a
heavy work table) to stop any possible
broken wheel parts.
5.
Workplace Hazards
Slip/Trip/Fall is a major cause of
serious injury or death. Beware of
excess hose left on the walking or
work surface.
High sound levels can cause
permanent hearing loss. Use hearing
protection as recommended by your
employer or OSHA regulation (see 29
CFR part 1910).
Maintain a balanced body position
and secure footing.
Repetitive work motions, awkward
positions and exposure to vibration
can be harmful to hands and arms.
If numbness, tingling, pain or
whitening of the skin occurs, stop
using tool and consult a physician.
Avoid inhaling dust or handling debris
from the work process which can be
harmful to your health. Use dust
extraction and wear respiratory protective
