Metabo DS 150 M Instrucciones De Manejo página 7

The grinder complies with protection class I and
must therefore only be connected to sockets
earthed according to specifications.
Always install an RCD / GFCI with a maximum
trip current of 30 mA upstream.
5.3 Installing workpiece support
Install workpiece support (10) as shown in
illustrations A, page 2.
5.4 Fitting spark deflector and eye
preservers
Install the spark deflector (13) and eye preservers
(11) as shown in illustrations B, page 2.
5.5 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.
5.6 Dust extraction connection (depending
on features)
If your machine is not equipped with a dust
extraction connection (7), fit an extraction device
that is suitable for bench grinders. Inner diameter of
extraction connection piece: 35 mm. Outer
diameter of extraction connection piece: 41 mm.
Before switching on the machine, ensure that the
extraction device is connected and being used
correctly.
5.7 Test run
Check the sanding discs 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 (10) frequently to
compensate for wear of the sanding discs (4).
The workpiece support must always be adjusted in
such a way that the angle between the workpiece
support and the tool is always greater than 85°.
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 2).
If the sanding disc is so badly worn that the
maximum distance of 2 mm can no longer be
maintained, the sanding disc must be replaced.
6.2 Adjusting the spark deflector
Adjust the spark deflectors (13) regularly to
compensate for wear on the grinding wheels (4).
Release the 2 screws on the spark deflector and
shift the spark deflector.
The distance between the spark deflector and
grinding wheel must be as small as possible and
never greater than 2 mm (see illustration C, page 2).
If the sanding disc is so badly worn that the
maximum distance of 2 mm can no longer be
maintained, the sanding disc must be replaced.
6.3 Switching on and off
Press the switch (14) (see illustrations D, page 2).
I = Switch on
0 = Switch off
Avoid inadvertent starts: always switch the tool off
when the plug is removed from the mains socket or
if there has been a power cut.
7. Maintenance and Cleaning
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.
Disconnect the mains plug before starting any
setting, cleaning, maintenance or repair work.
7.1 Sanding disc change
Use only original Metabo sanding discs.
The permissible rotational speed specified on
the sanding disc must be equal to or greater
than the maximum idling speed specified on the
identification plate of the machine.
Sanding disc check:
suspend the sanding disc on a thread. Knock
lightly with a piece of hard wood. You will hear a
clear tone if the sanding disc is in perfect condition.
If you hear a clattering, dull or hollow sound, the
grinding wheel is damaged.
Do not use damaged sanding discs.
Test run
A test run of approx. 5 min without load must
be carried out after the grinding wheel has been
changed. All persons must stay clear of the danger
zone when this is performed.
Sanding disc:
- Remove screws from safety cover (1) and take off
cover (1).
- Hold the sanding disc (4) firmly in position as
shown. Alternative option: Insert a hexagonal
wrench into the spindle and hold the spindle to
prevent if from turning. Caution! Risk of injury!
Wear protective gloves!
