Weight adjustment

The grinding pressure can be adjusted for different
applications by adding or removing weight off the back of
the electrical box. Below matrix shows grinding pressure
for each height and counterweight setting.

• Squeeze the handle on the central hinge and angle
the upper frame forward to its horizontal lifting
position.
• Loosen the 4 screws that holds the weight plates and
remove 1 or 2 plates to achieve the desired pressure.

Connect the vacuum cleaner

Use a Husqvarna dust extraction system for complete
dust control.
• Connect the dust extractor to the machine. Use a 50
mm (2 inch) hose.
Make sure that the filters in the vacuum cleaner are intact
and clean. Pay attention to dust during operation.
Grinding guide Diamonds
Background
The diamond segment comprises usually of two
components:
• Diamonds (also called diamond crystals or corn).
Changing the size of the diamonds or corn will change
the coarseness or fineness of the scratches after the
grinding process.
• A bonding agent (metal or plastic). Powder is mixed
and suspended in a metal or plastic bonding agent. If
metal is used as a bonding agent, the finished product
is called metal-bonded or sintered diamond segment.
If plastic is used as a bonding agent, the finished
product is called plastic-bonded diamonds or
polishing disc. By changing the hardness of the
bonding agent, you can change how quickly or slowly
the diamond abrasive is worn down.
