Operation And Maintenance - VERTO 51G098 Bedienungsanleitung

GRINDING
Grinding wheel, cup-type grinding wheels, flap wheels, wheels with
abrasive fibre, wire brushes and flexible discs, etc. should be used for
grinding. Each type of discs and workpiece requires proper working
method and personal protective equipment.
Cut-off wheels should not be used for grinding.
Grinding discs are intended for removal of material with an edge
of the disc.
• Do not use the lateral surface for grinding. The optimum
working angle for this disc type is 30° (fig. H).
• Works related to grinding can be performed only, when proper
grinding discs are used for a given workpiece.
When flap wheels, discs with abrasive fibre and flexible discs for
sandpaper are used, attention should be paid to the proper tool
angle (fig. I).
• Do not grind with the entire surface of a wheel.
• This disc type should be used for working flat surfaces.
Wire brushes are mainly used for cleaning sections and hard-to-
reach spaces. They can be used to remove rust, painting coats, etc.
from a workpiece surface (fig. K).
Only such working tools can be used, whose permissible
rotational speed is higher or equal to the maximum no load speed
of the grinder.

OPERATION AND MAINTENANCE

Before any operations related to installation, adjustment, repairs
or maintenance are commenced, the plug of the power cord
should be disconnected from the socket.
MAINTENANCE AND STORAGE
• It is recommended to clean the tool after each use.
• Do not use water or other fluids for cleaning.
• The tool should be cleaned with a dry piece of cloth or blown with
compressed air of low pressure.
• Do not use any cleaning agents or solvents, since they may damage
plastic parts.
• Venting slots in the motor housing should be cleaned on a regular
basis not to overload the tool.
• When the power cord is damaged, it should be replaced with
the power cord of the same parameters. It should be performed
by a qualified professional or the tool should be delivered to an
authorised service shop.
• When the commutator sparks excessively, have the condition of
motor carbon brushes checked by a qualified person.
• The tool should be always stored in a dry place and out of reach
of children.
REPLACING THE CARBON BRUSHES
Worn (shorter than 5 mm), burnt or cracked motor carbon brushes
should be immediately replaced. Both carbon brushes should be
always replaced at the same time.
Carbon brushes should be replaced by a qualified person using
original spare parts only.
All types of faults and defects should be eliminated by an authorised
service of the manufacturer.

NOISE AND VIBRATION DATA
Information regarding noise and vibration
The following levels of emitted noise, such as emitted acoustic
pressure Lp and acoustic power level Lw
A
uncertainty K have been given in the instruction manual as defined
in the EN 60745 standard.
The following vibration value (acceleration value) ah and measurement
uncertainty K have been determined as defined in the EN 60745
standard.
The vibration level provided in this instruction manual have been
determined according to the measurement procedure as defined
in the EN 60745 standard and can be used for comparison of power
tools. This can be used for preliminary assessment of exposure to
vibrations.
The provided vibration level is representative for main applications
of the power tool. If the power tool is used for other applications or
with other working tools, and if it is not sufficiently maintained, the
vibration level may vary. The aforementioned reasons may increase
the exposure to vibrations during the entire operating period.
In order to precisely estimate the exposure to vibrations, periods
should be accounted for, in which the power tool is switched off, or
when it is switched on, but not operated. Thus, the total exposure to
vibration may prove considerably lower.
Additional safety measures should be taken to protect the user
against effects of vibrations, such as: maintenance of the power tool
and its working tools, ensuring proper temperature of the hands and
proper organisation of work.
