5.6 installing the water collection system (accessory) 6
WARNING
Danger of electric shock! There is a possibility of water flowing over the motor and cover if the vacuum
removal system is faulty.
▶ Cease operations immediately if the vacuum removal system is not working.
CAUTION
Risk of injury! Inadvertent starting of the product.
▶ Unplug the supply cord before making adjustments to the power tool or before changing accessories.
For drilling upward, the diamond core drilling machine must be at a 90° angle to the underside of the
slab. The water collection system sealing disc must match the diamond core bit diameter.
Use of the water collection system allows water to be led away under control, thus preventing the
surrounding area from being heavily soiled.
1. Remove the screw from the drill stand.
2. Install the water collector holder on the drill stand with the screw.
3. Position the water collector, with seal and water collector sealing disc installed, between the two movable
arms of the water collector holder.
4. Press the water collector against the work surface by turning the two screws on the water collector
holder.
5. Connect a wet-type industrial vacuum extractor to the water collector or establish a hose connection
through which the water can drain away.

before use.
CAUTION
Risk of injury! Inadvertent starting of the product.
▶ Unplug the supply cord before making adjustments to the power tool or before changing accessories.
Replace diamond core bits as soon as their cutting performance and/or rate of drilling progress drops
significantly. This generally is the case when the diamond segments wear to a height of less than 2
mm (1/16 in).
A 27 mm open-ended wrench is required for C-Rod, A-Rod, M27 and BR chucks.SW 27
