Maintenance; Directions For Use - WOLFF BS 180 Original Bedienungsanleitung

3.4 Genuine Spare Parts
Spare parts and accessories are manufactured uniquely for the
Concrete grinding machine BS 180. It must be emphasized that
parts obtained from unauthorized sources must not be used.
Wolff cannot be held responsible for the performance of or any
damage arising from the use of machines in which genuine spare
parts have not been used. This is particularly important with
replacement blades.
3.5 Accessory
Speed control (accessory #015937)
Put the speed control into a socket you use with the BS 180. The
control reduces the power to 40 to 100 %. Thus the speed of the
BS 180 is controlled within 3.400 and 8500 r.p.m.

4.0 Maintenance

The Concrete grinding machine BS 180 is virtually maintenance-
free. The roller bearings and gear box need not to be lubricated.
The air inlet and outlet should be blown out from time to time to
avoid clogging. Failure to do so may result in stress being put on
the machine by overheating.

5.0 Use

5.1 Directions for use

Press the machine always with 2 hands towards the subfloor.
The spring-loaded suction ring limits the pressure of the
blade towards the ground and makes suction very efficient.
Check the power cord and the plug before starting.
Have damaged insulation repaired at once, before starting
Use faultless blades only! Worn blades give poor results.
A suitable vacuum cleaner may be connected with the machine.
Bodenschleifer BS 180, Artikel Nr. 015930
Always disconnect the power supply before changing
the blade. Unintended starting of the machine may cause
injury, e.g. of your hands.
If the brushes are to be replaced, the motor housing
may be opened only by qualified service-personnel.
Subsequent mounting of the new brushes requires
specialist knowledge.
