Maintenance And Cleaning; Environmetal Protection - Bosch GWS 14-180 Manual De Instrucciones

Test run!
Check grinding tools before use. Teh grinding tool must be
properly mounted and turn freely.
Perform a test run for at least 30 seconds with-out load. Do
not use damaged, out of round or vibrating grinding tools.
Operating instructions
• Clamp the workpiece in case it does not remain sta-
tionary by its own weight.
• Do not overload equipment so that it comes to a
standstill.
• Roughing and cutting discs become very hot while
working; do not touch before they have cooled.
Grinding
The best result are achieved with an angle of 15 o
to 40 o for grinding. Move the machine back and
forth with light pressure. In this manner, the work-
piece does not become too hot, no discoloration occurs and
no ridges are produced.
Under no circumstances should a cutting disk be
used for roughing work.
Fan Grinding Plate
With the fan grinding plate (accessory), curved surfaces
and profiles can also be worked (contour grinding).
Fan grinding discs have a much longer service life, lower noise
level and lower grinding temperature than grinding discs.
Cutting
When cutting, do not
press, tilt or oscilate.
Work with a moder-
ate feed rate that is suited to the
material to be worked.
The direction in which one cuts
is important. The machine must
always rotate opposite to the di-
rection of motion; therefore never
move the machine in the other
direction! Otherwise, the danger
exists that it will be forced uncon-
trolled out of the cut. When cutting profiles or square pipes, it
is best to start with the smallest cross section.
Attention!
• Never use a split grinding wheel.
• Do not drop the wheel or submit it to strokes (crack / fis-
sure hazard).
• Due to structural and technical differences in the manu-
facture of a grinding and cutting discs, don't use a cut
disc for grinding jobs or grinding disc for cutting jobs.
Use only griding/cutting disc correct to the worked mate-
rial, e.g.:
Ferrous material - aluminium oxide.
Non-ferrous materials - (aluminium, brass, copper, etc.) -
silicon carbide.
Cast iron - silicon carbide.
Stones - (marble, granite, concrete, etc.) - silicon carbide.
Obs.: For further details about grinding / cutting disc, con-
sult specialized stores or manufatures.
