Initial Operation - Metabo DS 125 Instrucciones De Manejo

en ENGLISH
Materials that generate dusts or vapours that may
be harmful to health (e.g. asbestos) must not be
processed.
The workpiece can become hot during grinding.
Do not allow water within the vicinity of electric
machine parts or close to people in the working
area.
If a grinding material blockage occurs, switch off the
grinder immediately, allow the motor to stop and
unplug the grinder. Identify the cause and remove
the blockage.
Clean, check and perform maintenance work on the
machine and guard devices regularly. Regularly
clean the inside of the grinding wheels housing. The
grinding wheels must be able to rotate freely within
the housing.
Unplug when the grinder is not in use, before
making any adjustments or carrying out
modifications, repairs or maintenance.
Regularly check the power cable on the grinder and have it repaired by an approved expert if damaged.
Regularly check extension cables and replace if
damaged.
Check the grinder for possible damage: Before
using the grinder, protective devices or slightly
damaged components must be carefully checked to
ensure they are operating perfectly and as
intended. Check that moving parts are in perfect
working order and do not jam and check whether
parts are damaged. All parts must be correctly
installed and fulfil all conditions necessary to ensure
perfect operation of the grinder. Damaged
protective devices and parts must be repaired or
replaced according to specifications by an
authorised specialist workshop.

5. Initial Operation

5.1 Power supply
Before plugging in, check that the rated mains
voltage and mains frequency, as stated on the
rating label, match with your power supply.
The grinder complies with protection class I and
must therefore only be connected to sockets
earthed according to specifications.
5.2 Installing workpiece support
Install workpiece support (8) as shown in illustrations
A, page 3.
5.3 Fitting spark deflector and eye
preservers
Install the spark deflector (10) and eye preservers (9)
as shown in illustrations B, page 3.
5.4 Installing machine safely
Place the machine on a stable workbench. Ensure
that the machine is securely seated.
The machine can also be bolted down (screws not
included in the scope of delivery). To do this, fasten
the securing screws through the holes in the rubber
feet.
If a stand or wall bracket is used (see Accessories
chapter): bolt down the machine.
5.5 Dust extraction connection (depending
on equipment)
If your machine is not equipped with a dust
extraction connection (6), fit an extraction device that
is suitable for double-wheeled bench grinders. Inner
diameter of extraction connection piece: 35 mm.
Before switching on the machine, ensure that the
extraction device is connected and being used
correctly.
5.6 Test run
Check the grinding wheels before initial use.
Test run
A test run of approx. 5 min without load must
be carried out before initial use. All persons must
stay clear of the danger zone when this is
performed.
. 6. Use
6.1 Adjusting the workpiece support
Adjust the workpiece supports (8) frequently to
compensate for wear of the grinding wheels (4).
The distance between the workpiece support and
grinding material must be as small as possible and
never greater than 2 mm (see illustration C, page 3).
If the grinding wheel is so badly worn that the
maximum distance of 2 mm can no longer be
maintained, the grinding wheel must be replaced.
