Fixing grinding disc
Pull out the power plug.
Depress and hold down the spindle lock to tighten the spindle. Turn the shaft until it was locked. Remove the
outer flange and tighten the flange using the special wrench provided.
Fit the desired disc on the inner flange and replace the outer flange and tighten the flange. Release the spindle
lock.
WARNING: only use wheels with maximum safe operating speed rated at or above the RPM listed on the
“WARNING”selection of the tool`s nameplate.This speed is based on the strength of the wheel,allowing for a
reasonable measure of safety,It is not meat to imply a best or most efficient operating speed ,Do not exceed the
Maximum Safe Operating Speed.
16. Dust-extraction system.
Dust released during the processing of materials such as paints containing lead, some wood, minerals and
metals can be hazardous to health. By skin contact or inhalation of such powders can cause allergic reactions
and / or respiratory illnesses to working with power tools or nearby persons. Certain powders, for example
released during the processing of beech and oak are considered to be carcinogenic, particularly in combination
with chemical treatment of wood (chromate, preservatives, 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. Swich 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
electric grinders in safety switch Fi (safety shut-off switch with Residual protection), and current leakage, which
is triggered when Fi should be no more of 30 mA.
Make periodic breaks at work.
Keep and refer to the accessories carefully.
18.2. Replacing the carbon brushes. Worn-out (shorter than 5 mm), or broken carbon brushes of the engine
should be replaced. Always replace both the two brushes. Work on replacement of carbon brushes entrusted
only to qualified specialists with original spare parts in service of RAIDER.
18.3. The repair of your power tool is best carried out only by qualified specialists in service RAIDER, which
