Ryobi A54ST02 Manual Del Operador página 12

Always operate trimmer with the switch trigger fully pressed.
Cut tall grass from the top down. This will prevent grass from
wrapping around the shaft housing and string head which may
cause damage from overheating. If grass becomes wrapped
around the string head, STOP THE MOTOR, remove the
battery pack for cordless power heads, or disconnect the
plug from the power source for electric power heads, and
remove the grass.
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.
CUTTING TIPS
See Figures 10 - 11.
„ Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating positions shown in
figure 10.)
„ Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
„ The trimmer cuts when passing the unit from left to right.
This will avoid throwing debris at the operator. Avoid cut-
ting in the dangerous area shown in figure 11.
„ 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 and break-
age. Stone and brick walls, curbs, and wood may wear
line rapidly.
„ Avoid trees and shrubs. Tree bark, wood moldings, sid-
ing, and fence posts can easily be damaged by the line.
„ Do not attempt to touch or stop moving accessory. Coast-
ing line can cause injury.
When using the flail blades:
„ Do not attempt to use the fixed line/blade housing for
edging. This will cause premature wear on the blades.
„ Inspect trimmer head before each use and periodically
during long periods of use. If either blade is bent, warped,
cracked, chipped, or damaged, discontinue use immedi-
ately and replace the blades.
OPERATION
„ Never cut any material over 1/4 in. diameter.
„ After releasing the switch trigger, keep rotating accessory
in thicker weeds or pulpy stalks until it stops. Maintain
proper control until the accessory has completely stopped
rotating.
WARNING:
To avoid damaging blades or fixed line/blade housing,
allow at least 1 foot of clearance between the blades and
any nearby objects. Never use blades near sidewalks,
fencing, posts, siding, buildings, or other immovable
objects. Damaged blades or accessories can cause seri-
ous personal injury.
ADVANCING THE CUTTING LINE
See Figure 12.
Line advance is controlled by tapping the string head on
grass while running motor at full speed.
NOTICE:
Failure to attach the grass deflector prevents the line
being cut to the proper length and can cause tool failure.
„ Run with the switch trigger fully pressed.
„ 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 MOTOR, remove the battery pack for cordless power
heads, or disconnect the plug from the power source for
electric power heads, and manually advance the line.
To advance the cutting line manually:
„ Stop the motor, remove the battery pack for cordless
power heads, or disconnect the plug from the power
source for electric power heads.
„ Push the bump knob in while pulling on line(s) to manually
advance the line.
