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, 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
