3. Lay the product on the ground and make sure that the
cutting means do not come in contact with anything.
4. Press the primer bulb 10 times.
5. Set the choke lever to position.
6. Hold down the throttle lock and then squeeze the
throttle trigger completely with your left hand and keep
the throttle trigger squeezed completely. Use the right
hand to put the electrical starter shaft into the shaft
hole on the engine. Make sure the starter is properly
engaged.
7. Press and hold the electrical starter switch button until
the engine starts.
NOTE: If the engine does not start, repeat the procedure
from step 5. Do not repeat the procedure more than
1 time. If the engine does not start after the second
attempt, see the solution instruction for the “Flooded
engine” in the “Troubleshooting” section of this manual.
STOPPING THE ENGINE:
■ Set the switch to the “STOP” (OFF) position.
OPERATING THE GRASS TRIMMER
Hold the product with the right hand on the rear handle
and the left hand on the front handle. Keep a rm grip with
both hands while in operation. The product should be held
at a comfortable position with the trigger handle about hip
height.
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
■ Avoid hot surfaces by always keeping the product away
from your body.
■ 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 IN SPEED WINDER 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 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
de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.
REPLACING THE SPEED WINDER STRING HEAD (FOR
RLT254CDSO ONLY)
■ Stop the engine.
■ Align the spanner along both flat side of arbor flange
washer.
■ Turn the string head counterclockwise by hand to
remove the old one.
■ Replace a new string head, align the nut in the string
head to the connector shaft of lower boom.
■ Turn the string head clockwise by hand to tighten,
recommended torque is 6 N.M.
REPLACING THE SPEED WINDER STRING HEAD (FOR
RLT254SDSO ONLY)
■ Stop the engine.
■ Place the combination wrench through the hole in the
upper flange washer and the hole in the gear head.
■ Turn the string head clockwise by hand to remove.
■ Replace a new string head, align the nut in string head
to gear box shaft.
■ Turn the string head counterclockwise by hand to
tighten, recommend torque is 6 N.M.
REPLACING THE LINE IN THE SPEED WINDER STRING
HEAD
■ Ensure the product is in “off” position.
■ Use a 2.4 mm diameter monofilament string.
■ Cut one piece of string approximately 5.4 m in length.
■ Rotate the bump knob clockwise as necessary to align
the arrows on the bump knob with the arrows on the
lower housing of string head.
■ Insert one end of the string into the eyelet located on
the side of the string head and push until string comes
out through eyelet on the other side.
■ Continue to push string through the string head until
the middle section of the string is inside the string head
and string outside the string head is evenly divided on
each side.
■ Rotate the knob on the string head clockwise to wind
the line.
■ Wind the string until approximately 20 cm remains
protruding from the string head.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount
of lubricant used, and/or your operating conditions, the
exhaust port and silencer may become blocked with carbon
