CUTTING WITH A BLADE
CUTTING WITH A BLADE
There are many different types of blades,
however the two most commonly used are the following.
BRUSHBLADE is used for cutting brush and weeds up to 3/4" in diameter. Only CG420-2
255mm 3-blade can be used in this type of brush cutter.
SAWBLADE is used for cutting growth from 3/4" to 3" in diameter.
WARNING
DANGER
DO NOT USE A BRUSH CUTTER FOR CUTTING TREES.
WARNING
DANGER
Do not cut with dull, cracked or damaged metal blade.
Before cutting growth, inspect for
obstructions such as boulders, metal stakes or strands of wire from broken fences. If an
obstruction cannot be removed, mark its location so that you can avoid it with the blade. Rocks
and metal will dull or damage a blade. Wires can catch on the blade head and flap around or be
thrown into the air.
Blade thrust is the reaction which may occur when the spinning blade contacts anything it cannot
cut.This contact may cause the blade to stop for an instant ,and suddenly "thrust" the unit away
from the object that was hit.This reaction can be violent enough to cause the operator to lose control
of the unit.Blade thrust may occur without warning if the blade snags ,stalls or binds.This is
more likely to occur in areas where it is difficult to see the material being cut.For cutting ease and
safely,approach the weeds being cut from the right to the left,in the event that an unexpected object
or woody stock is encountered,this could minimise the blade thrust reaction.
SCYTHING WEEDS
This is cutting by swinging the blade in a level arc. It can quickly clear areas of field grass and
weeds. Scything should not be used to cut large, tough weeds or woody growths.
