Additional Safety Instructions - Hilti AG 125-A36 Bedienungsanleitung

▶ The grinding surface of centre depressed wheels must be mounted below the plane of the guard
lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately
protected.
▶ The guard must be securely attached to the power tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the operator. The guard helps to protect the operator from
broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
▶ Wheels must be used only for recommended applications. For example: do not grind with the side
of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
▶ Always use undamaged wheel flanges that are of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel flanges.
▶ Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may burst.
Additional safety warnings specific for abrasive cutting-off operations:
▶ Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or wheel breakage.
▶ Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible kickback may propel the spinning wheel and the
power tool directly at you.
▶ When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of wheel binding.
▶ Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
▶ Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece on both sides of the wheel.
▶ Use extra caution when making a "pocket cut" into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

2.2.3 Additional safety instructions

Personal safety
▶ Tampering with or modification of the power tool is not permitted.
▶ Wear ear protectors. Exposure to noise can cause hearing loss.
▶ Always hold the power tool with both hands on the grips provided. Keep the grips dry, clean and
free from oil and grease.
▶ Respiratory protection must be worn if the power tool is used without a dust removal system for
work that creates dust.
▶ Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶ Avoid touching rotating parts. Switch the power tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating accessory tools (discs etc.), may lead to injury.
▶ The power tool is not intended for use by debilitated persons who have received no special training.
Keep the power tool out of reach of children.
▶ Dust from materials, such as paint containing lead, some wood species, concrete/masonry/stone
containing silica, and minerals as well as metal, may be harmful. Contact with or inhalation of the dust
may cause allergic reactions and/or respiratory or other diseases to the operator or bystanders. Certain
kinds of dust, such as oak and beech dust, are classified as carcinogenic, especially in conjunction with
additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be
handled only by specialists. Use a dust removal system whenever possible. To achieve a high level
of dust collection, use a suitable vacuum cleaner. When indicated, wear a respirator appropriate
for the type of dust generated. Ensure that the workplace is well ventilated. Observe national
regulations applicable to the materials you intend to work with.
▶ The user and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear
protection, protective gloves and breathing protection while the power tool is in use.
▶ If the power tool detects that it is being operated beyond its limits or if the battery is fully discharged, it
may happen that the accessory tool is no longer braked by the motor.
