MOUNTING AND REMOVING AN ACCESSORY (FIG. 4)
This tool uses threaded core bits and adaptors
which thread directly onto the spindle (d).
We recommend to use professional accessories
only.
1. Choose the appropriate core bit for wet or dry
drilling.
2. Follow the core bit or manufacturer's
recommendations for mounting the accessory.
You may require an adaptor to fit the bit onto
the spindle.
3. Hold the spindle using the open-ended
wrench (o) and tighten the core bit (p) by
rotating clockwise using the open-ended
wrench (q).
WARNING: Make sure the entire
assembly is tight before starting the
operation.
Two Gear Selector (fi g. 1)
The tool is fitted with a two gear selector (f) to vary
the speed/torque ratio.
1. Release the switch and select the required
position after the motor has come to a
complete standstill.
2. Always align the selector with the marks on the
gear housing.
3. Refer to the technical data to choose the
appropriate gear according to the diameter of
the core bit and the material to be drilled.
4. Do not change gears at full speed or during
use.
