etc.).. Where possible, use dust-extraction system. Provide good ventilation in the workplace. Use of
respiratory mask with a filter of class P2.
17. Working with angle grinders.
17.1. Beware of the voltage of the supply network! Supply voltage of the network must conform
to the details shown on the plate of power. Appliances marked with 230 V, can be supplied with a
voltage of 220 V.
17.2. In the grinding power generators that do not have sufficient capacity, respectively. Have
appropriate control voltage to increase the starting current for inclusion can be observed a temporary
drop in power or unusual behavior of the grinding machine. Please make sure you use the generator
is appropriate, especially in 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 switch (2) after that pushing the ON/OFF switch (1). To switch off the angle grinder, release
the button (1). 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.
