CLEANING

9, Large Bushing
During break-in period (about 10 hours of use),
bushing teflon moves toward cam or shaft sur-
face. A teflon over teflon running condition occurs,
leading to low friction. So it is normal to see gray
teflon deposit on cam or shaft. Do not remove that
deposit, it is not dust.
When a dust deposit has to be removed from the
cam or the shaft, use dry cloth to avoid removing
transferred teflon.
Pulley Half Cleaning
Use Pulley Flange Cleaner (P/N 413 711 809).
