Speed and direction of rotation
The product has Dual Drive technology. Dual Drive
technology means that the grinding head and the
grinding discs operate with different motors. The speed
and direction of rotation can be set independently
between the grinding head and grinding discs. To set
the speed and direction of rotation independently
increases the range of different surface types where the
product can be operated. Speak to your Husqvarna
dealer or go to www.husqvarnacp.com for more

Operation speed
If the product is operated on a new surface type, set the
speed to 70% initially. When the operator knows the
surface type, the speed can be adjusted.
Direction of rotation of the grinding head and
the grinding discs
Seen from below the product, the direction of rotation is
as follows:
• "REV": clockwise
• "FWD": counterclockwise
The operation result is best when the grinding head and
the grinding discs rotate in the same direction.
During operation the product can pull to the side. The
direction of the pull is related to the direction of rotation.
The product pulls to the right when the direction of
rotation is set to "FWD". The product pulls to the left
when the direction of rotation is set to "REV".
The side pull can help you operate the product for
example near a wall. Set the direction of rotation to pull
in the direction of the wall.
CAUTION: Steer the product carefully. Make
sure that the product only lightly touches the
wall. The product is heavy and can cause
damage.
To change the speed and direction of rotation
of the motors
Change the direction of rotation regularly to increase the
life and the sharpness of the diamond tools. The
diamond tool segments are used equally and the contact
surface continues to be as large as possible.
• To set the speed and direction of rotation of the
grinding head, turn the knob (A).
