Ryobi RY26901 Brush Cutter User Manual


 
11 — English
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around
the shaft housing and string head which could cause
damage from overheating. If grass becomes wrapped around
the string head, STOP THE ENGINE, disconnect the spark
plug wire, and remove the grass. Prolonged cutting at partial
throttle will result in lubricant dripping from the muffler.
WARNING:
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 (BUMP FEED
STRING HEAD)
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.
Run engine at full throttle.
Tap the knob on ground to advance line. The line advances
each time the knob is tapped. Do not hold the knob on
the ground.
NOTE: The line trimming cut-off blade on the grass deflector
will cut the line to the correct length.
NOTE: If the line is worn too short you may not be able to
advance the line by tapping it on the ground. If so, stop the
engine, and manually advance the line.
To advance the cutting line manually:
Stop the engine and disconnect the spark plug wire.
Push the knob in while pulling on line(s) to manually ad-
vance the line.
CUTTING TIPS
See Figures 16 -17.
Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 15.)
Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
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.
OPERATION
Use the tip of line to do the cutting; do not force string
head into uncut grass.
Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the line.
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 line until it
is trimmed to length by the cut-off blade. Advance the line
whenever you hear the engine running faster than normal,
or when trimming efficiency diminishes. This will maintain
best performance and keep the line long enough to advance
properly.
OPERATING THE BRUSHCUTTER
See Figures 19 - 20.
Hold the brushcutter with your right hand on the rear handle
and the your hand on the “J” handle. Keep a firm grip with
both hands while in operation. Brushcutter should be held at
a comfortable position 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 operator 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. This 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.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
