CAUTION
Cutter blades have two cutting edges.
Exercise caution when working around the
blades. Blades are sharp and can cause
serious injury. Wear gloves when handling
blades.
CAUTION
Damaged blades may damage the
cutterbar, and result in poor cutting
performance. Replace damaged blades at
earliest possible opportunity.
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
a. Check daily that the cutter blades are securely
attached to the disc.
b. Check blades for cracks or wear beyond safe
operating limits, and distortion.
c. Replace blades immediately if any of these
problems occur.
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.
