Cutting Tips - Ryobi RY29550 Manual Del Operador

cHARgINg A HOT BATTERY PAcK
When using the tool continuously, the batteries in the
battery pack will become hot. You should let a hot battery
pack cool down for approximately 30 minutes before
attempting to recharge.
NOTE: This situation only occurs when continuous use
of the string trimmer causes the batteries to become hot.
It does not occur under normal circumstances. Refer to
cHARgINg THE BATTERY PAcK for normal recharging
of batteries. If the charging assembly does not charge the
battery pack under normal circumstances, return both the
battery pack and charging assembly to your nearest Ryobi
Authorized Service Center for electrical check.
TO INSTALL BATTERY PAcK
See Figure 8.
 Place the battery pack in the string trimmer. Align raised
rib on battery pack with groove in string trimmer's battery
port.
 Make sure the latches on each side of the battery pack
snap in place and that battery pack is secured in string
trimmer before beginning operation.
TO REMOVE BATTERY PAcK
 Locate latches on side of battery pack and depress both
sides to release battery pack from the string trimmer.
 Remove battery pack from the string trimmer.
OPERATINg THE TRIMMER
See Figure 9.
WARNINg:
Always position the unit on the operator's right side. The use of the unit on the operator's left side will expose
the user to hot surfaces and can result in possible burn
injury.
WARNINg:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with your right hand on the rear handle
and your left hand on the front 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
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.
TO ADVANcE THE cUTTINg LINE
String 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 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 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 string.
To advance the cutting line manually:
 Stop the engine and disconnect the spark plug wire.
 Push the knob in while pulling on string(s) to manually
advance the string.

cUTTINg TIPS

See Figures 9 - 10.
 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 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 string to do the cutting; do not force string
head into uncut grass.
 Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
 Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the string.
gRASS DEFLEcTOR STRINg TRIMMINg cUT-
OFF BLADE
See Figure 11.
The trimmer is equipped with a string trimming cut-off blade
on the grass deflector. For best cutting, advance string until
it is trimmed to length by the cut-off blade. Advance the
string whenever you hear the engine running faster than
normal, or when trimming efficiency diminishes. This will
maintain best performance and keep the string long enough
to advance properly.
