that dirt causes a blockage in the water
system.
CAUTION: Use only an approved water
supply coupling. Speak to your dealer for
more information.
1. Attach the water connector to the mounting thread
on the product. (Fig. 15)
2. Connect the Gardena
valve to the water connector.
3. Open the water system. Set the water pressure to
remove all waste material from the drill hole.
To decrease the temperature of the

To operate the product
WARNING: If the PRCD engages, remove
the drill bit from the hole before you push
"RESET".
WARNING: Dangerous accidents can occur
if the concrete core stays in the drill bit when
you remove the drill bit from the hole.
CAUTION: Make sure that no objects hit the
drill bit.
CAUTION: Do not use more force than
necessary. This only makes the operation
slow and causes overload to the motor.
1. Start the motor. Refer to
page 12 .
2. Let the motor speed increase to the maximum speed
before the drill bit touches the surface.
3. If you drill through iron reinforcements, use more
initial pressure and a lower gear than if there were
no iron reinforcements.
4. Use very small pressure initially to keep the drill bit in
correct position.
5. If wet drilling, make sure that the water removes all
waste material from the drill hole. Adjust the water
pressure if it is necessary.
6. If dry drilling, make sure that the dust extractor
removes all dust.
7. Stop the motor. Refer to
