Failure of the considered instructions may lead to electric shock, fire and / or severe injuries.
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
A
= 89 dB (A)
Sound power level: Lw
A
= 100 dB (A)
Work with earmuffs!
Level of vibration a
h
= 5.3 m/s
2
In rough surface grinding and polishing: vibrations generated: a
h
= 13 m/s
2
,
uncertainty K = 1,5 m/s
2
.
Sanding with sandpaper: vibrations generated a
h
= 4,8 m/s
2
, uncertainty K = 1,5 m/s
2
. The 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 (6).
Place the guard (6) of the uptake step of grinding. Adjust the position of the guard (6) according to
a specific activity carried out. Place the guard (6) so as to prevent sparks scatter at work.
15.1.2. Auxiliary handle (4).
Use your angle grinder fitted with only auxiliary handle (4). Curl handle as (4) 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 (3) to block shaft grinders.
Press the button for locking the shaft only when it is stationary. Otherwise, the grinding may be
damaged.
15.3. Disc for sanding or cutting.
Respecting limit the amount of work tools. The diameter of the hole to fit a foot flange alignment.
Do not use adapters or reducing units. When mounting the diamond blades careful arrow indicating
their direction of rotation to coincide with the direction of rotation of grinding (see arrow on the grinding
head). For locking a disc grinder or cutting curl locking nut (8) and tighten with the special key. After
mounting of abrasive disc before turning angle grinder, make sure that the disk is installed properly
and can rotate freely. Make sure that the abrasive disk is not touching the guard or other details of
the grinding machine.
15.4. Bell disc or wire brush.
Used cupped wire brush or disc must be able to winding shaft grinding machine so that it touches
the flange firmly to the shaft at the end of the thread. Tighten cupped disk or wire brush with a spanner.
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,
