GENERAL SAFETY RULES
■
For multiple hazards, read and understand the safety
instructions before installing, operating, repairing,
maintaining, changing accessories on, or working
near, the grinder. Failure to do so can result in serious
bodily injury.
■
Only qualified and trained operators should install,
adjust or use the grinder.
■
Do not modify this grinder. Modifications can reduce
the effectiveness of safety measures and increase the
risks to the operator.
■
Do not discard the safety instructions; give them to the
operator.
■
Do not use the grinder if it has been damaged.
■
Tools shall be inspected periodically to verify that the
ratings and markings required by this part of ISO 11148
are legibly marked on the tool. The employer/user
shall contact the manufacturer to obtain replacement
marking labels when necessary.
PROJECTILE HAZARDS
■
Be aware that the failure of the work piece or
accessories, or even of the inserted tool itself, can
generate high-velocity projectiles.
■
Always wear impact-resistant eye protection during
the operation of the grinder. The grade of protection
required should be assessed for each use.
■
Ensure that the work piece is securely fixed.
■
Ensure safe clamping of the abrasive product to the
grinder.
■
Check that maximum operating speed of the abrasive
product, converted to revolutions per minute, is equal
to, or greater than, the rated speed of the spindle.
■
Ensure that the guard is in place, is in good condition
and is correctly mounted; ensure that the guard is
regularly inspected.
■
Check regularly that the speed of the grinder is not
higher than that marked on it. These speed checks
shall be carried out without the abrasive product
mounted and in accordance with the instructions given
by the manufacturer.
■
Check that the flanges, as specified by the
manufacturer, are used and are in good condition, e.g.
free from cracks and burrs, and are plane.
■
Check that the spindle and spindle threads are not
damaged or worn.
■
Ensure that sparks and debris resulting from use do
not create a hazard.
■
Disconnect the grinder from the energy supply before
changing abrasive product and servicing.
ENTANGLEMENT HAZARDS
Choking, scalping and/or lacerations can occur if loose
clothing, personal jewelry, neck wear, hair or gloves are
not kept away from the tool and accessories.
OPERATING HAZARDS
■
Avoid contact with the rotating spindle and
mounted wheel to prevent cutting of hands and
other body parts.
Use of the tool can expose the
operator’s hands to hazards, including cuts, abrasions
and heat. Wear suitable gloves to protect hands.
■
Operators and maintenance personnel shall be
physically able to handle the bulk, mass and power
of the tool.
■
Hold the tool correctly; be ready to counteract normal
or sudden movements and have both hands available.
■
Maintain a balanced body position and secure footing.
■
Release the start-and-stop device in the case of an
interruption of the energy supply.
■
Use only lubricants recommended by the manufacturer.
■
Personal protective safety glasses shall be
used; suitable gloves and protective clothing are
recommended.
■
For overhead work, wear a safety helmet.
■
The stopping time, if longer than 5 s, shall be stated,
and it shall be recommended that the grinder be
placed in a stable position.
■
When cutting off, the work piece shall be supported
such that the slot is kept at constant or increasing
width during the complete operation.
■
If the abrasive product becomes jammed in a cut
slot, shut off the grinder and ease the wheel free.
Check that the wheel is still correctly secured and not
damaged before continuing the operation.
■
Grinding wheels and cutting-off wheels shall not be
used for side grinding. (Exception: grinding wheels
designed for side grinding.) Grinders shall not be used
over the maximum peripheral speed of an abrasive
product.
■
The operator shall pay attention that no bystanders
are in the vicinity.
■
Personal protective equipment, such as suitable
gloves, an apron and a helmet, shall be used.
■
Grinding sparks can ignite clothing and cause severe
burns. Ensure sparks do not land on clothing. Wear
fire-retardant clothing and have a bucket of water
nearby.
