Mannesmann 12555-STS350 Instruction Manual page 55

- Store the grinding wheels in their original packaging or in special containers and on
special shelves.
Installing of the side handle (supplementary handle)
Always firmly fix the side handle to the machine before start-up. The side handle can be firmly
installed optionally in one of the two positions on the side of the machine depending on which
position is best suited and which ensures correct positioning of the protective hood.
When using the machine to grind with two hands (with one hand on the operating handle and
the other on the side) hold it firmly and securely.
Replacement of Abrasive Discs
 Disconnect the mains plug before replacing the abrasive disc.
 Keep the locking button (1) pressed and loosen the tightening nut with the enclosed
spanner.
 Remove the tightening nut and the abrasive disc from the tightening shaft.
 When inserting a new abrasive disk make sure that it is seated correctly on the tightening
flange.
 Retighten the tightening nut, making sure that the abrasive disc is not damaged in this
process.
 Before commencing work, try the machine and check to make sure that the disc is rotating
correctly.
Before initial operation
 Mains voltage: Ensure that the mains voltage used corresponds to the information on the
type plate.
 Power switch: The ON/OFF button cannot be locked in the ON position.
 Extension cable: If the work area is not close to the mains connection, an extension cable
of sufficient horizontal and rated output is to be used. The extension cable should be kept as
short as possible.
 Installing and setting of the protective hood: The protective hood is a protective device
which should prevent damage if the grinding wheels were to break during operation. It must
be ensured that the hood is properly attached and fastened before the grinding work starts.
Thanks to slight loosening of the locking screw, the protective hood can be turned and
adjusted to every desired angle. It must be ensured that the locking screw is properly
tightened after the adjustment of the protective hood.
 Ensure that the appropriate grinding wheel and the other parts are installed in accordance
with the manufacturer's instructions. It must also be ensured that the grinding wheel that is
to be used is of the correct model and that it has no cracks or surface defects. It must also
be ensured that the grinding wheels are correctly mounted and the screw nut of the grinding
wheel is firmly tightened. See section "installing the grinding wheels".
 Ensure that the recommended washers are used when they are delivered with grinding
wheels made from bonded abrasives.
 Do not use separate bushing or adaptors to adjust grinding wheels with a large hole.
 Do not use a cut-off wheel for side-grinding.
 Carrying out a test run: Before use, make sure that the grinder is correctly installed and
firmly secured, and let the machine run without a load for 30 seconds in a secure location.
