SPEED STABILIZATION
This machine is equipped with an electronic speed stabilization system which maintains constant speed under
load.
VARIABLE SPEED FUNCTION
The motor's speed can be varied to suit the needs of different work
situations. Turn the Variable Speed Thumbwheel clockwise to increase
speed and anti-clockwise to decrease.
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.
On the BS-1255 model, press the Tab, slide the Half-Moon Door
outward to unlock, then rotate the Half-Moon Door to the side until it
clicks.
On the BS-1805, one may remove the Half-Moon Door by pushing
inward on the two clips. This will expose the Edge Cut-Out in the
skirt. The Half-Moon Door may be temporarily adhered to the handle
crossbar using its magnet.This will allow the Grinding Head reach
right up to the edge. Dust collection will not be ideal so replace the
door as soon as access to the Edge Cut-Out is no longer needed.
