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.
If the use of a guard is recommended for wire brushing,
do not allow any interference of the wire wheel or
brush with the guard. Wire wheel or brush may expand in
diameter due to work load and centrifugal forces.
Additional Safety and Working
Instructions
Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate
of the machine.
Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility company
for assistance. Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property damage or
may cause an electric shock.
Release the On/Off switch and set it to the off position
when the power supply is interrupted, e. g., in case of a
power failure or when the mains plug is pulled. This pre-
vents uncontrolled restarting.
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health and cause allergic reactions, lead to res-
piratory infections and/or cancer. Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
After breakage of the grinding disc during operation or
damage to the holding fixtures on the protection guard/
power tool, the machine must promptly be sent to an after-
sales service agent for maintenance. For addresses, see
section “After-sales Service and Application Service”.
Adjust protection guard in such a manner that sparking
toward the operator is prevented.
The protection guard may only be turned while actuat-
ing the release lever on the gear head. Otherwise, the
machine may not continue to be used anymore and
must be sent to an after-sales service agent.
Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
After mounting the grinding tool and before switching
on, check that the grinding tool is correctly mounted
and that it can turn freely. Make sure that the grinding
tool does not graze against the protection guard or oth-
er parts.
When operating the machine with power from mobile
generators, loss of performance or untypical behavior
can occur upon switching on.
By applying too high application force, the machine can
be subject to overload. Overload can lead to overheat-
ing and damage of the power tool. After heavily strain-
ing the power tool, continue to run it at no-load for sev-
eral minutes in order to cool it down.
Do not use the power tool with a cut-off stand.
Never use a cutting disc for roughing.
The quick-clamping nut may be used only for grinding
or cutting discs. Use only a flawless, undamaged quick-
clamping nut.
Do not pull out the gear head while turning it –
see figure 12, page 270.
To save energy, only switch the power tool on when using
it.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.
