Additional Safety Instructions - Hilti GDG 6-A22 Original Bedienungsanleitung

Safety warnings specific for grinding and abrasive cutting-off operations:
▶ Use only wheel types that are recommended for your power tool and only for recommended
applications. For example: do not grind with the side of a cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
▶ For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and length. Proper mandrels will reduce the possibility of
breakage.
▶ Do not "jam" a 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 snagging of
the wheel in the cut and the possibility of kickback or wheel breakage.
▶ Do not position your hand in line with and behind the rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible kickback may propel the spinning wheel and the
power tool directly at you.
▶ When wheel is pinched, snagged 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 pinching or snagging.
▶ 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.
Safety warnings specific for wire brushing operations:
▶ Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not
overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate
light clothing and/or skin.
▶ Allow brushes to run at operating speed for at least one minute before using them. During this
time no one is to stand in front or in line with the brush. Loose bristles or wires will be discharged
during the run-in time.
▶ Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments
may be discharged at high velocity during the use of these brushes and may become imbedded in your
skin.
2.3 Battery use and care
▶ Observe the special regulations and instructions applicable to the transport, storage and use of Li-ion
batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. In this case, place the product in a non-flammable
location, well away from flammable materials, where it can be kept under observation and allowed to
cool down. In this case, always contact your Hilti Service.

Additional safety instructions

▶ When using the product, hold it in such a way that grinding dust, flying sparks and possible flying
fragments of the accessory tool or workpiece cannot hit you.
▶ When changing the accessory tool, use only neatly fitting and undamaged wrenches.
▶ Accessory tools must run perfectly round. Do not use accessory tools that are out of round.
▶ Do not attempt to remove chips or splinters of material while the product is still running. Switch the
product off.
▶ Switch the power tool on only after it is in position at the workpiece.
▶ Wear protective gloves when changing accessory tools, because the accessory tool and the chuck get
hot during use.
▶ Take breaks between working and do relaxation and finger exercises to improve the blood circulation in
your fingers. Exposure to vibration during long periods of work can lead to disorders of the blood vessels
and nervous system in the fingers, hands and wrists.
