Cutting Tips; Maintenance - Ryobi RY4CCS Manual Del Operador

CUTTING TIPS

See Figures 9 - 11.
 Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 9.)
 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.
 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.
TO ADVANCE THE CUTTING LINE
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.
 Run engine at full throttle.
Normal maintenance, replacement or repair of emission
control devices and systems may be performed by any
qualified repair establishment or individual with original
or equivalent parts. Warranty and recall repairs must be
performed by a authorized service center; please contact
customer service for assistance.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
OPERATION
 Tap the bump 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 bump knob down while pulling on line(s) to
manually advance the line.
GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE
See Figure 12.
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.
