4.5 Motor and centrifugal clutch
General
The centrifugal clutch
•
ensures power transmission between motor, drive belt and spindle.
•
brings the bowl gradually to rated speed,
•
eliminates premature wear to drive belt and motor.
Note that the driving effect of new clutch shoes will improve after several starts.
Smoking of the clutch during the first few starts is perfectly normal and will dis-
appear after a short time of operation.

If the bowl reaches its rated speed in
less than 1.5 minutes (see nameplate)
resulting in an inadmissibly high motor
current consumption during start-up,
(I
max
>1.8 x I
N
),
•
reduce the number of clutch shoes,
•
be sure to keep the clutch shoes
evenly spaced.
•
Wear to the clutch shoes depends on
– number of start-ups,
– ejection frequency.
•
Check the condition of the clutch shoes from time to time (see 4.2.1 - Mainte-
nance schedule).
•
Always replace all clutch shoes at the same time to avoid imbalance.
Never replace individual clutch shoes!
