Additional safety warnings for grinding and cut-off

grinding

Safety warnings specific for grinding and cut-off

grinding:

Use only grinding accessories that are approved for your

power tool and only for the recommended applications.

Example: Never grind with the lateral surface of a cutting

disc. Cutting discs are intended for material removal

using the edge of the disc. Lateral force exerted on these

grinding accessories can cause them to break.

For threaded conical and straight grinding points/acces-

sories, use only undamaged mandrels of correct size and

length with an unrelieved shoulder flange. Suitable man-

drels will reduce the possibility of breakage.

Do not jam or seize the cutting disc or apply excessive

pressure. Do not make excessively deep cuts. Overstress-

ing the cutting disc increases the loading and susceptibility

to wedging or binding in the cut, and thus increases the

possibility of kickback or disc breakage.

Keep your hands clear of the area in front and behind the

rotating cutting disc. When moving the cutting disc in the

workpiece away from your hand, possible kickback may

propel the power tool with the spinning disc directly at

you.

If the cutting disc should become jammed or when inter-

rupting work, switch the power tool off and hold it

motionless until the disc has come to a complete stop.

Never attempt to remove a still running cutting disc from

the cut, otherwise there is danger of kickback. Deter-

mine and correct the cause for the jamming.

Do not switch the power tool on again as long as the disc

is still in the workpiece. Allow the cutting disc to reach

its full speed first before carefully continuing with the

cut. Otherwise the disc can bind, be forced out of the

workpiece or cause kickback.

Support panels or large workpieces to minimise the risk

of kickback from a jammed cutting disc. Large work-

pieces tend to sag under their own weight. The work-

piece must be supported on both sides of the cutting disc,

near the cut and also at the edges of the workpiece.

Use extra caution when making “pocket cuts” into exist-

ing walls or other blind areas. The protruding cutting disc

may cut gas or water pipes, electrical wiring or other

objects that can cause kickback.

Additional safety warnings for working with wire

brushes

Safety warnings specific for wire brushing opera-

tions (GSZ8-90PEL, GSZ11-90PERL, GSZ4-90EL):

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, make sure

that no one is standing in front or in line with the brush.

Loose bristles or wires can be discharged or thrown off

during the run-in time.

Direct the rotating wire brush away from yourself. Small

particles and tiny wire fragments may be discharged at

high velocity during the use of these brushes, and may

penetrate through your skin.

Safety warnings specific for polishing operations

(GSZ8-90PEL, GSZ11-90PERL, GSZ4-90EL):

Do not allow for any loose parts of the polishing bonnets,

especially fastening cords. Stow away or shorten the fas-

tening cords. Loose, rotating fastening cords can take

hold of your fingers or become caught or entangled in the

workpiece.

Further safety warnings

Make sure that the application tools are mounted in

accordance with the manufacturers instructions. The

mounted application tools must be able to rotate freely.

Incorrectly mounted application tools can become loose

during operation and be thrown from the machine.

Handle grinding accessories carefully and store them

according to the manufacturer’s instructions. Damaged

grinding accessories can develop cracks and burst during

operation.

When using application tools with a threaded insert, take

care that the thread in the application tool is long enough

to hold the spindle length of the power tool. The thread in

the application tool must match the thread on the spindle.

Incorrectly mounted application tools can loosen during

operation and cause injuries.

Do not direct the power tool against yourself, other per-

sons or animals. Danger of injury from sharp or hot

application tools.

Beware of any concealed electric cables, gas or water

conduits. Check the working area before commencing

work, e. g. with a metal detector.

Use a stationary extraction system, blow out ventilation

slots frequently and connect a residual current device

(RCD) on the line side. When working metal under

extreme operating conditions, it is possible for conduc-

tive dust to settle in the interior of the power tool. The

total insulation of the power tool can be impaired.

Do not rivet or screw any name-plates or signs onto the

power tool. If the insulation is damaged, protection

against an electric shock will be ineffective. Adhesive

labels are recommended.

Before putting into operation, check the mains connec-

tion and the mains plug for damage.

Recommendation: The tool should always be supplied

with power via a residual current device (RCD) with a

rated current of 30 mA or less.

Hand/arm vibrations

The vibration emission level given in this information

sheet has been measured in accordance with a standard-

ised test given in EN 60745 and may be used to compare

one tool with another. It may be used for a preliminary

assessment of exposure.

The declared vibration emission level represents the

main applications of the tool. However, if the tool is used

for different applications, with different accessories or

poorly maintained, the vibration emission may differ.
