Summary of safety instructions – part 1
Electrical connection
Failure to observe the values on the data plate can cause damage to the
electrical and mechanical components.
Start - Interrupt - Stop
When sieves with a diameter of  400mm are used, only operate the AS400 to a maximum speed of 200
r.p.m.. Otherwise the sieve stack mass could create such large imbalances that the device slews out of
control in wild movements. Or fasten the AS400 as described in the chapter "Assembly".
Setting the speed in "r.p.m." from 050-300
Never start at the maximum speed of 300 r.p.m., but rather increase the speed slowly. When using sieves
with diameters from 400mm and the max. sieve stack, do not set the speed higher than 200 r.p.m.. Oth-
erwise the masses set in motion too quickly can displace, causing the AS400 to tip over. Or fasten the
AS400 as described in the chapter "Assembly".
Sieving aids
Ensure that the fabric of the sieve is not overstretched by overloading with sieving aids as this would have
a detrimental effect on the precision of your analytical sieve.
Cleaning
Do not clean the AS400 control with running water. Danger to life from electrical shock
Only use a rag moistened with water. Never use solvents.
Parts subject to wear and tear
These operating instructions do not contain any repair instructions. In the interests of your own safety,
repairs should only performed by Retsch GmbH or an authorised representative (service technician).
