7.1 Locking the spindle
DW 10-125 Quick:
- Press in the spindle locking button (7) and turn the
spindle (9) by hand until you feel the spindle
locking button engage.
DW 125:
- Place the open-end spanner (11) supplied on the
spindle (9) to prevent co-rotation.
7.2 Placing the grinding wheel in position
See illustration A on page 2.
- Fit the support flange (10) on the spindle. (9) The
flange should not turn on the spindle when prop-
erly attached.
- Place the grinding wheel on the support flange
(10).
The grinding wheel must lie flat on the supporting
flange.
7.3 Securing/releasing the (tool-free) clamp-
ing nut (depending on features)
Only tighten the (tool-free) clamping nut (12)
manually.
For the machine to operate, the clip (13) must
always lie flat on clamping nut (12) .
To secure the (tool-free) clamping nut (12):
Do not use the (tool-free) clamping nut if the
mounted tool has a clamping shank thicker
than 6 mm! In this case, use the clamping nut (14)
with 2-hole spanner (15).
- Lock the spindle (see Section 7.1).
- Flip up the clip (13) on the clamping nut.
- Fit the clamping nut (12) on the spindle (9).
- (13)Tighten the clamping nut on the clip manu-
ally in a clockwise direction.
- Flip down the clip (13) again.
To release the (tool-free) clamping nut (12) :
- Lock the spindle (see Section 7.1).
- Flip up the clip (13) on the clamping nut.
- Unscrew the clamping nut (12) , turning it anti-
clockwise manually .
Note: If the clamping nut is very tightly secured (12),
you can also use a 2-hole spanner to unscrew it.
7.4 Securing/releasing the clamping
nut(depending on features)
Securing the clamping nut (14):
The 2 sides of the clamping nut are different. Screw
the clamping nut onto the spindle as follows:
See illustration B on page 2.
- A) For thin grinding wheels:
the edge of the clamping nut (14) faces upwards
so that the thin grinding wheel can be attached
securely.
B) For thick grinding wheels:
the edge of the clamping nut (14) faces down-
wards so that the clamping nut can be attached
securely to the spindle.
20
- Lock the spindle. Turn the clamping nut (14)
clockwise using the 2-hole spanner (15) to
secure.
Releasing the clamping nut:
- Lock the spindle (see Section 7.1). Turn the
clamping nut (14) anticlockwise using the 2-hole
spanner (15) to unscrew.
8. Use
8.1 Using the air tool
To benefit from the air tool's full performance,
always use compressed air hoses with an inner
diameter of at least 9 mm. Tool performance can be
significantly impaired if the inner diameter is too
small.
Caution. The compressed air line must not
contain any water condensation.
Caution. To preserve and extend the service
life of this tool, you must ensure that it is regu-
larly maintained with pneumatic oil lubricator. You
can do this as follows:
– Use oiled compressed air by fitting an oil-fog lu-
bricator.
– Without an oil-fog lubricator: manually apply oil
every day via the compressed air connection.
Use approx. 3-5 drops of pneumatic oil lubricator
for each 15 minutes of continuous operation.
If the tool has not been in use for several days, you
should manually apply about 5 drops of pneumatic
oil lubricator into the compressed air connection.
Caution. Only allow the tool to run at idle
speed for a brief period.
Always guide the machine with both hands.
Switch on first, then guide the mounted tool
towards the workpiece.
After switching off the machine, only set it
down when the motor has come to a standstill.
1. Attach the appropriate mounting tool.
2. Adjust the supply pressure (this is measured at
the air outlet while the air tool is switched on).
For details of the maximum permissible supply
pressure, see the section on "Technical Specifi-
cations".
3. Connect the air tool to the compressed air sup-
ply.
4. To switch on: slide the switch-on lock (4) in the
direction of the arrow and press the switch (3).
To switch off: release switch (3).
8.2 Working instructions
Grinding:
press down the machine evenly on the surface and
move back and forth so that the surface of the work-
piece does not become too hot.
Roughing: position the machine at an angle of 30° -
40° for the best working results.
