A
CAUTION: Never attempt any
service
of
the trimmer head
without first shutting
off
the
engine and allowing the
implement to come to a complete stop.
The shield is an important device which is intended to
help prevent the operator’s feet from coming into contact
with the cutter implement and reduce the amount
of
flying debris.
Do
not operate
the
trimmer without the
shield in place.
