9.2 Dismantling Drill Chuck
Danger
Danger due to unintentional start-up of the machine.
You must shut down the machine prior to starting any maintenance or cleaning
work.
The different machines types use two basic procedures to disassemble the
drill chuck:
Spindle with hexagon nut
Spindle with pin opening
9.2.1 Dismantling drill chuck with hexagon screw
Attention
Damage to the spindle or drill chuck.
Make sure that when dismantling the chuck, it does not fall onto the drilling ta-
ble or vise. This can cause damage to components and render them unsuita-
ble for further use.
1. Switch off the machine (see section 7.1 Switching the machine off, page
52).
2. Swivel the drill guide to the left side.
Attention
Danger due to hot cutter.
The cutter may still be hot after use. Cool the cutter with coolant or remove it
with a protective glove.
3. First, remove the cutter from the chuck before disassem-
bling the chuck.
4. Hold the drill chuck tight with one hand so that it does not
fall onto the drilling table or vice after dismantling and is
damaged.
5. Use a suitable hexagon wrench to turn the WFA24 hexa-
gon nut clockwise to loosen the chuck.
6. Remove the chuck.
7. Check the drill chuck for dirt, wear or damage.
8. Also check the spindle for dirt, wear or damage.
