This tool is solely determined for cutting slots and setting sockets in
masonry, brick, limestone and lightweight materials. Materials releas-
ing noxious dust or steam during the work may not be treated. Im -
proper use may cause injury or damage the tool.
Switch on the tool and press first the front roller (F) against the wall,
then slowly enter the cutter into the wall, until the two rollers lie
against the wall. Only then push the tool in the cutting direction. The
arrow on the tool indicates the cutting direction and is situated just
above the cutting slot.
During the operation, the tool must be held with both handles, as when
touching metal parts, radio interference suppression is not guaranteed.
Core bits can be attached only in depth position 4. Screw the core bit
(BK 106) onto the tool spindle (stalwart) with a shaft. Insert the pilot
drill bit into the shaft of the core bits and twist it up clock-wise to
stop.
Only genuine tools may be used. When using other tools, the cutter
spindle and the machine might be damaged.
This control has the following advantages:
– a smooth start
– idle speed limitation (low noise)
– 2 speeds
– running current limitation: if the tool is overloaded, the running
current limitation protects the motor by reducing the current flow to
an admissible degree. The motor stops and purrs.
When the feed is now reduced, the motor will gently start again.
The tool does not have to be removed from the wall.
Lime stone is an extremely abrasive, tool-wearing building material.
Therefore only chase lime stone in the low speed [position I, selection
of speed (D)]. This way cutters and core bits will last longer. When
treating other building materials in common use, the high speed (posi -
tion II) is recommended.
