ANGLE GRINDER
-
When plug or switch are damaged or only have loose contact
-
When the grinding disc is rotating unevenly and/or in case of intense sparking the
electric tool has to be repaired immediately. It must then not be operated anymore.
Always keep the electric tool clean. The vent holes have to be kept free and there
must net be any contaminant, as e.g. chipping in the holes.
Do always handle the electric tool with care and caution. Avoid cuffs against the
grinding disc. Grinding discs must never get wet nor freeze
Do not overload the electric tool. Do only operate it within the specified range of
capacity.
6. MAINTENANCE AND REPAIR
This electric tool is operating with a very high r.p.m. Therefore, it is necessary to
clean the spindle bearing regularly and to replenish or change the bearing grease.
The electric tool has to be regularly checked for correct operation and, if applicable,
repaired. The inspection comprehends flex, wires and electric connections inside
the tool, plug, switch, insulation, carbon brushes, grinding disc, spindle bearing,
moving parts, etc.
In order to avoid accidents, the electric tool has to be disconnected from the power
supply before any maintenance or repair takes place
If the electric tool has been operated in a damp environment or not been used for
a long time the insulation resistance between enclosure and coil has to be
measured before using the tool again. Use an instrument in the MΩ range at a
direct voltage of ca. 500 V for this purpose. The coil has to be dried if the insulation
resistance is less than 7 M
Ω. If the electric tool is damaged, it has to be repaired
by qualified personnel.
Unsuitable tools and improper repairs can cause injuries. The electric tool might be
damaged.
In this case, the manufacturer bears no responsibility for injuries or damage and
the warranty will lapse.
