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 9 .

Cause
The product is connected to the pow-
er pack and can be operated.
Power output is less than 70% of
available output during operation.
Power output is between 70% and
90% of available output during opera-
tion.
Power output is more than 90% of
available output.
Max. power output.
There is a risk that the product be-
comes too hot.
The product is too hot and can sud-
1
denly stop.
The max. available output is auto-
matically decreased to prevent over-
heating and automatic stop of the
product.
2. Let the motor speed increase to the maximum speed
before the drill bit touches the surface.
3. Push the drill bit into the surface with the feed lever.
4. If you drill through iron reinforcements, use more
initial pressure and a lower gear than if there were
no iron reinforcements.
5. Use very small pressure initially to keep the drill bit in
correct position.
6. During operation, make sure that the water removes
all waste material from the drill hole. Adjust the water
pressure if it is necessary.
7. Stop the motor. Refer to
11 .
Load indicator
CAUTION: Do not cause overload to the
product again and again as this damages
the product. The load indicator shows the
power output which does not always mean
the best recommendation for the operation.
