Ensure the spring-loaded net knife is tripped before working in this area. With the brake lever upright, adjust the mechanism so the net roll brake pads rock slightly and the disc can be rotated with a little resistance to keep the net correctly tensioned also that the net feed-in roller spring coils are no more than 1-2mm apart. Replace the grey foam roller if damaged to prevent net snagging but don't straighten the curved bar inside - it's like that to spread the net. Keep knives and other sharp implements away from the rubber feed-in roller - the slightest cut can cause snagging - instead of scraping, wash debris away with warm, soapy water and a sponge.
