terms of voltage and frequency.
17.3. Outdoor use.
Connect the machine only in installations equipped with electric switch Fi (safety
shut-off switch with Residual protection), and current leakage, which is triggered
when Fi must be no more than 30 mA.
17.4. Switch on.
The angle grinder comes with a safety switch which is designed to prevent accidents.
To switch on, push the slide switch (2) to the right while at the same time pushing the
ON/OFF switch (1) forwards and depressing. To switch off the angle grinder, depress
the button (1) at the back. The switch (1) will jump back into its starting position. Check
the working tools before using them. Work tools must be impeccably mounted and
spinning without touching anything. Leave it to rotate without a load test at least one
minute. Do not use damaged, beating or vibrating work tools. Damaged work tools can
break and cause serious injuries.
Before the disc to touch the work surface, the machine should work with maximum
speed.
Be careful when cutting channels in the bearing walls. Before starting work, consult
with the responsible civil engineer, architect or manager of a construction site.
Lock work pieces properly.
Do not overload grinding to the extent that its rotation to stop.
In operation, discs for grinding and cutting is very hot, do not touch them before
they cool.
17.5. Rough grinding.
Never use blades for rough grinding.
When running under gradient of 30° to 40° when sanding will get the best results.
Move with moderate pressure grinding back and forth. Thus, the piece will not be
overheated, the surface to change color and will be formed deep furrows.
17.6. Sanding with flap disk.
With flap disc you can grinding curved surfaces also.
17.7. Cutting metal.
When cutting, work with moderate, consistent with the material being processed
submission. Do not pinch cutting disc, do not jam or perform with him swirling motion.
When you turn implies that the disc does not forcibly stop. Cutting of profiles and pipes
with rectangular cross-section is best to start cutting the smallest cross-section.
17.8. Scission of stone materials.
Use of angle grinder for dry cutting and dry grinding.
When cutting stone materials, it is best to use a diamond cutting disc. Use only the
included angle grinder dust absorb system and work with a dust mask to breathe.
Especially when cutting hard materials such as concrete with high content of gravel,
diamond cutting disc may be overheated and damaged. Indication for that it is the
emergence of a sparkling crown. In this case, disconnect and wait for the diamond
cutting disc to cool, leave it to spin some time idling at maximum speed. Significantly
reduced cutting speed and the appearance of sparkling crown are indications of
"blunt diamond cutting disc. You can "imprisoned" by short-cutting abrasive material,
for example silicate brick.
18. Maintain and service.
18.1. Maintenance and cleaning.
Before carrying out any activities grinders unplug the plug from the feed network.
To work quality and safe, keep grinding and vent clean.
In extremely severe working conditions in cutting of metal on the inner surfaces
of the body may be delayed powder in which current flows. This can disrupt the
protective insulation of the grinding machine. In such cases, it is recommended to
use a fixed aspiration system, the frequent blowing of the vent and the inclusion of
