6. Operation
6.1 Before using the tool for the first time
Insert plug-in nipple (12).
6.2 Inserting the collet chuck
The tool's shank diameter must correspond
exactly to the collet bore of the collet chuck (3)!
DG 25 Set: Various collet chucks are available for
different shank diameters.
Insert the collet chuck (3) into the collet chuck
holder (4) and manually tighten the collet chuck nut
(2).
If there is no tool inserted in the collet chuck,
you can tighten the collet chuck manually
rather than with the open-end spanner.
6.3 Attaching the accessory
For small grinding tools, the maximum permis-
sible projection allowed by the manufacturer
(L ) must not be exceeded! Insert the accessory
0
with the full length of the shank if possible into the
collet chuck (3). Ensure that the clamping length
(L ) is at least 10mm.
g
The accessory's shank diameter must corre-
spond exactly to the collet bore of the collet
chuck (3).
- Bring the spindle (5) to a standstill using the open-
end spanner (6).
- Tighten the collet chuck nut (2) using the open-
end spanner (1).
- Ensure that the accessory is fitted securely.
6.4 Using the pneumatic tool
To benefit from the pneumatic tool's full perfor-
mance, always use compressed air hoses with an
inner diameter of at least 10 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.
1. DG 25 Set: Select a suitable collet chuck (3)
(see Chapter 6.2).
2. Fit an appropriate accessory (see Chapter 6.3).
3. DG 25 Set: You can adjust the speed on the
adjusting screw (9).
4. Adjust the supply pressure (this is measured at
the air outlet while the pneumatic tool is
switched on). For details of the maximum per-
missible supply pressure, see the Chapter on
"Technical Specifications".
5. Connect the pneumatic tool to the compressed
air supply.
6. To switch on: Push the switch-on lock (8) in the
direction of the arrow (see Fig., Page 2) and
press switch (7).
To switch off: Release switch (7)
.
