Operating The Trimmer; Cutting Tips - Ryobi RY254BC Manuel D'utilisation

CUTTING TECHNIQUE - BLADE
See Figure 15.
WARNING:
Extreme care must be taken when using blades to ensure
safe operation. Read the safety information for safe
operation using the blade, refer to Specific Safety Rules
for Brush Cutter and Blade Use earlier in this manual.
 Always hold brush cutter on your right side with both
hands when operating. Use a firm grip on both handles.
 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.
 Inspect and clear the area of any hidden objects such as
glass, rocks, concrete, fencing, wire, wood, metal, etc.
 Never use blades near sidewalks, fencing, posts,
buildings or other immovable objects.
 Never use a blade after hitting a hard object without first
inspecting it for damage. Do not use if any damage is
detected.
 The unit is used as a scythe, cutting from the right to the
left in a broad sweeping action from side to side.
 Use only the TRI-ARC
blade or cutting head to this brush cutter can result in
serious personal injury.

OPERATING THE TRIMMER

See Figure 16.
Hold the trimmer with your right hand on the rear handle
and your left hand on the J-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.
OPERATION

™
TO ADVANCE THE CUTTING LINE (REEL
EASY 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 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 in while pulling on line(s) to manually
advance the line.

CUTTING TIPS

See Figure 17.
 Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 16.)
 Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
 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.
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.
