To Advance The Cutting Line; Cutting Tips; Operating The Brushcutter; Blade Thrust - Ryobi CS30 Operator's Manual

A wnnrulruc'
Always hold the string trimmer away from the body keep-
ing clearance between the body and the product. Any
contact with the housing or string trimmer cutting head can
result in burns and/or other serious personal injury.
TO ADVANCE THE CUTTING LINE
String advance is controlled by tapping the string head on
grass while running engine at full throttle.
I Run engine at full throttle.
r Tap the spool retainer on ground to advance string. The
string advances each time the spool retainer is tapped.
Do not hold the spool retainer on ihe ground.
NOTE: The line trimming cut-off blade on the grass deflector
will cut the line to the correct length.
NOTE: lf the string is worn too shod you may not be able to
advance the string by tapping it on the ground. lf so, stop
the engine, and manually advance the string.
TO ADVANCE THE CUTTING LINE MANUALLY
I Stop the engine.
I Push the spool retainer down while pulling on string(s) to
manually advance the string.
CUTTING TIPS
See Figures 16 -17.
r Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 1 5.)
r Keep the trimmer tilted toward the area being cut; this is
the best cuiting area"
r The curved shaft trimmer cuts when passing the unit from
right to left. The straight shaft trimmer cuts when passing
the unit from left to right. This will avoid throwing debris at
the operator. Avoid cutting in the dangerous area shown
in illustration.
r Use the tip of string to do the cutting; do not force string
head into uncut grass.
I Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
I Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the string.
GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE
See Figure 18.
The trimmer is equipped with a line trimming cut-off blade
on the grass deflector. For best cutting, advance string until
it is trimmed to length by the cut-off blade. Advance the
string whenever you hear the engine running faster than
normal, or when trimming efficiency diminishes. This
maintain best performance and keep the string long
to advance properly.
OPERATING THE BRUSHCUTTER
See Figures 19 - 20.
Hold the brushcuiter with your right hand on the rear handle
and the your hand on the "J" Barrier Handle. Keep a firm
grip with both hands while in operation. Brushcutter should
be held at a comfortable oosition with the rear handle about
hip height. Maintain your grip and balance on both feet.
Position yourself so that you will not be drawn off balance
by the kickback reaction of the cutting blade.
Adjust the shoulder harness to position the brushcutter
at a comfortable operating position and to assure that the
shoulder harness will reduce the risk of ooerator contact
with the blade.
BLADE THRUST
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction that may occur when the
spinning blade contacts anything it cannot cut. Thrs contact
may cause the blade to stop for an instant, and suddenly
"thrust" the unit away from the object that was hit. This re-
action can be violent enough to cause the operator to lose
control of the unit. Blade thrust can occur without warning
if the blade snags, stalls, or binds. This is more likely to oc-
cur in areas where it is difficult to see the material being cut.
For cutting ease and safety, approach the weeds being cut
with the brushcutter from the right to the left. In the event
an unexpected object or woody stock is encountered, this
practice could minimize the blade thrust reaction.
A wnnrurruc,
To avoid burns from hot surfaces, never operate unit with
the bottom of the enoine above waist level.
TRI-ARC@ BLADE
The Tri-Arc@
blade is suited only for thicker weeds and pu lpy
stalks. When the blade becomes dull, it can be turned over
to extend the life of the blade. Do not sharpen the Tri-Arc@
blade.
Use only Tri-Arc@ blade, part number AP04105, available at
your local retailer.
