Reset the circuit breaker.
Adjust the web tension in Web Tension menu.

iator with suitable degreasing agent.
Possibly spray the belt with special spray.
Tighten the variator belt.
Check, and possibly change, the number of
weights on the SPINNER dancing roller accu-
mulator.
Low pressure on the nip roller, it should be 3
bar.
Pressure between cooling bars too low. Check
by pulling a bag through the bars. See
"Adjustment of cooling bar pressure" on page

Polish the carbon and copper lines with emery
cloth. Possibly exchange the carbon for new
item.
Exchange the seal wire for new item.
NOTE that when exchanging the seal wire,
Teflon and silicon, must be replaced on all
seal wires at the same time.
Sharpen the knives and reset them. They must
not hit to hard against the anvil roller.
Check the setting.
Check to make sure that the shaft encoder is
fitted securely on the variator.
Exchange the shaft encoder for new item.
