For chiselling, a MV 200 SDS-plus chiselling
attachment (accessory), which is inserted into
the SDS-plus tool holder 1, is required.
Inserting Screwdriver Bits (see figure H)
.
To work with screwdriver bits, a universal bit
holder 21 with SDS-plus shank (accessory) is
required.
.
Clean the shank end of the adapter shank and
apply a light coat of grease.
If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
Because of the forces that occur, always
hold the power tool firmly with both hands
and provide for a secure stance.
If the power tool jams, switch the machine
off and loosen the tool insert. When switch-
ing the power tool on with the drilling tool
jammed, high reaction torques can occur.
