Ryobi RY34422 Manual Del Operador página 14

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
advance the line.
CUTTING TIPS
See Figures 12 - 13.
 Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 11.)
 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.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product 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.
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.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, lubricant, grease, etc.

OPERATION
MAINTENANCE
10 — English
 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 14.
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.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
You can often make adjustments and repairs described here.
For other repairs, have the trimmer serviced by an authorized
service dealer.
