11.3 The blade guide system
In general usage it is advisable to carefully apply silicon spray
to the blade guides to ensure free movement of the rollers,
do not use oil or grease for lubrication as this will attract dust
and cause the rollers to jam. The blade guide system is a
consumable item and depending on usage will wear and need
replacing.
When replacing components on the upper guide assembly first
ensure that the blade is removed. Undo hex nuts
A & B
then
remove the guard.
