IS necessary to fit your own
blades, this
IS done as follows:
1. Identify left-hand and r~ght-hand blades.
2. The left-hand end flange carries two right-hand
blades. the right-hand end
carries two left-hand blades.
3 The centre flange (or flanges, depending on the
rnachlne width), carries two left-hand and two right-
hand blades leading The blades should be fitted to the
left-hand side of the centre
flange(s), with the heads

of the bolts against the blades and spring washers and
nuts against the flange.
