Cleaning & Servicing; Disassemble & Storage - Heidolph RZR 1 Betriebsanleitung

Cleaning: wipe housing clean with a damp cloth (add some sort of mild liquid soap).
Note
To avoid damage to the surface finish, avoid using chlorine bleach, chlorine-based
detergents, abrasive substances, ammonia, rags or cleaning agents containing
metal particles.
Servicing
Motor and gear are fitted with attendance-free ball bearings and are constructed for continuous
running. Subject to wear in such a gear is the friction lining, here the friction rubber. If the friction
rubber has to be replaced one day, it can be done directly in the laboratory without considerable
display. For this purpose the gear housing is opened by loosening of the fastening screws, and
the main shaft with the friction wheel is removed. By means of a screw-driver the friction rubber
can be taken away and replaced by a new one. Please notice that friction gears must not be
lubricated or greased. When replacing the friction rubber you have therefore to pay attention
that the friction cone must not be covered by an oil or grease film. For scouring you can use
petroleum ether or sprit of wine.The construction of the gear is done in reversed sequence.
Service life of the friction rubber depends on the precise pressure. The pressure of the friction
cone acting against the friction wheel is adjusted correctly, if at adjustment-position "10" the
motor comes to standstill at braking of the driving shaft. At letting loose of the driving shaft the
motor must start immediately. This can be ascertained by taking a look through the slots of the
motor hood.
The item is maintenance-free. Repair work is limited to technicians approved or appointed by
HEIDOLPH Instruments. Please call your local HEIDOLPH Instruments Dealer or a HEIDOLPH
Instruments Field Representative.
