Spark Arrestor - Ryobi PLT-3043S Owner's Operation Manual

MAINTENANCE
You may make adjustments and repairs described here.
For other repairs, have the trimmer serviced by an
authorized servicing agent.
Consequences of improper maintenance may include
excess carbon deposits resulting in loss of performance
and discharge of black oily residue dripping from the
muffler.
Make sure all guards, straps, deflectors and handles are
properly and securely attached to avoid the risk of
personal injury.
SPOOL REPLACEMENT
EZ LINE™ TAP ADVANCE SYSTEM
NEW PREWOUND SPOOL (FIG. 12 & 13)
If replacing line only, refer to "Line Replacement" later in
this manual.
Use only 2.4 mm (.080 in.) diameter monofilament line.
Use the manufacturer's replacement line for best perfor-
mance.
1. Stop the engine, disconnect the spark plug wire. Hold
the bump head (7) and unscrew the bump knob (32). Turn
clockwise.
2. Remove the empty spool (50) from the bump head. Keep the
spring (36) attached to the spool.
3. To install the new spool, make sure the two lines are
captured in the slots (33) opposite each other on the new
spool. Make sure the ends of each line is extended
approximately 152 mm (6 in.) beyond each slot.
4. Thread the lines into the eyelets (34) in the bump head.
Carefully push the spool into the bump head (gently pull
the lines to the outside if necessary). When the spool
is positioned in the bump head, grasp the lines and
pull sharply to release them from the slots in the spool.
5. Push down and turn the spool counterclockwise until it
no longer turns. Hold the spool down and rotate clock-
wise a small amount. Release the spool. The spool
should be locked down in the bump head. If not, hold
down and rotate until locked.
6. Make sure the bump head and the bump knob are
installed on the drive connector (35) turning the knob
counterclockwise to tighten.
7. Pull the lines again to rotate the spool into cutting
position. Push the bump knob down while pulling on
line(s) to manually advance the line and to check for
proper assembly of the bump head.
LINE REPLACEMENT (FIG. 14 & 17)
1. Stop the engine, disconnect the spark plug wire.
Hold the line head and unscrew the bump knob.
Turn clockwise.
2. Remove the spool from the bump head. NOTE:
Keep the line attached to the spool. Remove any
old line remaining on the spool.
3. Cut two pieces of line, each being approximately
2.7 m (9 ft.) long.
4. Insert the first line (37) into the anchor hole (38) in the
upper part of the spool. Wind the first line around
the upper part of the spool counterclockwise, as
shown by the arrows on the spool (39). Place line in
the slot on upper spool flange, leaving about 152
mm (6 in.) extended beyond the slot. Do not overfill.
After winding the line, there should be at least 6
mm (1/4 in.) between the wound line and the
outside edge of the spool.
5. Repeat above step with second line (40), using the
bottom part of spool. Do not overfill.
6. Replace the spool and the bump knob. Refer to
"Spool Replacement " earlier in this manual.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and muffler may become blocked with carbon deposits. If
you notice a power loss with your petrol powered tool, a
qualified service technician will need to remove these
deposits to restore performance.
