Gear shifting
The DBM 230 is equipped with a mechanical 3-gears transmission in oil bath.
Adjust the rotation speed of the engine to the drill diameter (for details see
identification plate).
Turn the gear switch to a faster/slower gear until it arrests. Gears must only be
shifted when the engine is at stand-still. It may be necessary to support the
switching operation by slightly turning the lead screw.
Warnung!
Never use force, shift gears only when the motor decelerates or is at stand-still!
Do not use tools e.g. wrenches, hammers for gear shifting!
Changing the drill bit
The drill spindle has a right-hand thread.
To retain the spindle use an open-end wrench 32mm on the drill spindle.
Never remove the drill bit by hitting it (with a hammer) as this will cause damage
to the core drill tool. Putting some waterproof grease on the drill spindle thread
and a copper ring placed between the spindle and the drill bit will further facilitate
the removal of the drill bit.
Caution!
The tool is heavy and may heat up during operations or
sharpening. You could burn your hands, cut, tear or squash
yourself on the segments.
Before working on the equipment pull the power plug. Raise
the engine retainer with the core drill until it arrests in the
final position. Always wear protective gloves when changing
tools.
