VACUUM CONNECTION
WARNING: Dust developing while working can be harmful to one’s health.
This machine is designed specifically for dry grinding of concrete and similar materials. It uses dry diamond cup
wheels and must be used with a suitable vacuum cleaner. Never exhaust the dust directly into the
atmosphere.
To attach vacuum hose to Dust Port, hold machine firmly with one hand. Then with a twisting motion push the
vacuum hose onto the Dust Port.
SAFETY GUARD
The Safety Guard (ie. the Skirt) must be used at all times when operating this machine. It is not adjustable. The
Half-Moon Door may be temporarily removed to expose the Edge Cut-Out. See below.
THE EDGE CUT-OUT
When working against a wall or into a corner, the Skirt will prevent
the grinding head from reaching all the way to the edge.
Press the Tab, slide the Half-Moon Door outward to
unlock, then rotate the Half-Moon Door to the side until it clicks.
