MAINTENANCE AND SERVICING

IMPORTANT

Blades should be replaced in pairs, otherwise
the disc may be unbalanced and damage
the cutterbar.

IMPORTANT

The cutter blades have cutting edges on
both edges so that the blade can be turned
over and reused.

The twist in each blade

determines if its cutting direction is clockwise
or counterclockwise.

If you are unsure which

direction the spindle rotates, see Section

7.6.3

Direction of Spindle Rotation, page 129
