Maintenance - Ryobi RLT254CDSO User Manual

Always operate the product at full throttle. Prolonged
cutting at partial throttle will result in lubricant dripping from
the silencer. Cut tall grass from the top down. This will
prevent grass from wrapping around the shaft housing and
bump head which may cause damage from overheating. If
grass becomes wrapped around the bump head, stop the
engine, and remove the grass.
CUTTING TIPS
See fi gure 6.
■ Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating position shown in
figure 5.)
■ Keep the product tilted toward the area being cut; this
is the best cutting area.
■ The product cuts when passing the product from
right to left. This will avoid throwing debris at the
operator. Avoid cutting in the dangerous area shown
in illustration.
■ Use the tip of the string to do the cutting; do not force
the string head into the uncut grass.
■ Wire and picket fences cause extra string wear, even
breakage.
■ Stone and brick walls, kerbs and wood may wear
string rapidly.
■ Avoid trees and shrubs. Tree bark, wood mouldings,
cladding and fence posts can be easily damaged by
the string.
ADVANCING THE LINE
See fi gure 7.
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 string. The string
advances each time the head is tapped. Do not hold
the knob on the ground.
NOTE: The line trimming cut-off blade on the grass
defl ector will cut the line to the correct length.
NOTE: If the string is worn too short, you may not be able
to advance the string by tapping it on the ground. If so,
stop the engine, and manually advance the line.
ADVANCING THE CUTTING LINE MANUALLY
■ Stop the engine.
■ Push the knob in while pulling on string(s) to manually
advance the line.
