prevent uncontrolled inclusion of angle grinders.
12.3. In the processing of stone materials, work with external dust-extraction system. Using
suction of the powder system limits damage to your health caused by dust.
12.4. During operation keep grinding hard with both hands and lend a stable position of the
body. With both hands, grinding water safer.
12.5. Provide work piece. Detail, and attach with appropriate appliances or braces is

cable is damaged, do not touch. Immediately disconnect the plug from the outlet.
Damaged power cables increase the risk of electric shock.
Failure of the considered instructions may lead to electric shock, fire and / or severe

13. Functional description and purpose of the grinding machine.
Is a manual power grinder with insulation class II. He is powered with the help of a collector
single-phase motor whose speed is reduced by means of a conical gear with curved teeth.
Angle grinder is designed for cutting, grinding and coarse wire brushes to clean metal and
stone surfaces without using water. With special accessories for grinding, grinding can be
used for sanding with sandpaper. Not be used for the grinding operations other than its
intended purpose.
14. Information emitted noise and vibration.
The values are measured according to EN 60745.
Sound pressure level: Lp
Sound power level: Lw
Work with earmuffs!
Level of vibration a
In rough surface grinding and polishing: vibrations generated: a
uncertainty K = 1,5 m/s
Sanding with sandpaper: vibrations generated a
level of generated vibrations can be used for comparison with other power tools. That level of
vibration generated is representative of the most common uses of angle grinder. If grinding
is used for other activities, working with other instruments or if not maintained as prescribed,
the level of generated vibrations can be changed.
15. Preparing for the job.
15.1. Installation of protective equipment.
Before carrying out any activities grinders unplug the plug from the feed network.
15.1.1. Guard (5).
Place the guard (5) of the uptake step of grinding. Adjust the position of the guard (5)
according to a specific activity carried out. Place the guard (5) so as to prevent sparks scatter
at work.
15.1.2. Auxiliary handle (3).
Use your angle grinder fitted with only auxiliary handle (3). Curl handle as (3) depending on
the mode of operation of the machine left or right of the head.
15.2. Mounting of grinding tools.
Before carrying out any activities grinders unplug the plug from the feed network.
In operation for grinding discs and cutting heat strongly not touch them before they cool.
Clean the shaft and all the details that will mount. When tightening and releasing the button
press working tools (2) to block shaft grinders.
Press the button for locking the shaft only when it is stationary. Otherwise, the grinding
may be damaged.
