Plug in mains plug

Main switch not switched on

Switch on main switch

Mains fuse blown

Replace mains fuse

Line fuse of mains socket

Switch on or change the fuse in

the fuse box

Rattling noises

Tension belt loose

Tighten tension belt

Amplitude larger than 3 mm

Set amplitude to less than 3 mm

Large control fluctuations around set point Sieve stack loose

Tighten toothed belt

Screws of laminated spring

assembly loose

Re-tighten the screws (8Nm)

Flat springs defective

Check flat springs for tears,

replace laminated spring assembly

if necessary

Flat springs too warm

Allow to cool down

Sieving stock not dispersed evenly on the

sieve surface

Toothed belt tightened unevenly

Tighten toothed belt evenly

The device is not level

Level the device again by turning

the feet
