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.

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.
General Principles
General rules for using diamond tools when grinding
follow below. As with all rules, there are exceptions or
occasions when they do not apply.
Diamond grit size
Changing the size of the diamond grit to a smaller
particle/grit size will effect the performance of the
diamond tool in the following ways:
Create a finer scratch pattern.
Increased service life of diamond tools.
The opposite will occur when changing to a larger
particle/grit size.
