Three rectangular wear limit marks are
applied to the base (periphery) of the
Polycut. To reduce the risk of serious
injury from breakage of the head or
blades, the Polycut must not be used
when it has worn as far as one of these
marks. It is important to follow the
maintenance instructions supplied with
the head!

Kickout (blade thrust) is the sudden and
uncontrolled motion towards the
operator’s right or rear that can occur
when the shaded area of the rotating
blade comes in contact with a solid
object like a tree, rock, bush or wall.
The rapid counterclockwise rotation of
the blade may be stopped or slowed,
and the cutting attachment may be
thrown in an area to the right or to the
rear.
This kickout (blade thrust) may cause
loss of control of the brushcutter and
may result in serious or fatal injury to the
operator or bystanders. To reduce the
risk of injury, extreme caution should be
used when cutting with the shaded area
of any rigid blade.
