SECTION
Tor0 offers
two
20 cm
(8
inches) blades that
fit
the
straight shaft trimmer line. The eight tooth blade is
designed for cutting brush and heavy weeds up to about
1.3 cm (1/2 inches). The eighty tooth blade should be
used in heavy brush and
if
scrub trees greater than 2 cm
(3/4") are present.
When using either blade, a harness is required to help
maintain adequate control.
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.
Metal Blade Removal

shaft.

clockwise (the nut uses left hand threads).

brush blade for the first time, you will require the Metal
Blade Adapter Kit for Gas Trimmer, Tor0 part number

should be a perfect
fit
between the lower gearbox
cover flange and the hub on the blade.

is important to install the blade
with the teeth pointing
in
the correct direction.
Make sure that they are pointing as shown
in

top of the shield to prevent the blade from turning
while tightening the nut.
See
Figure 159.
