MAINTENANCE

LINE REPLACEMENT (FIG. 12 - 15)
1. Stop the engine, disconnect the spark plug wire.
Hold the bump head and unscrew the bump knob.
Turn counter-clockwise.
2. Remove the spool from the bump head. NOTE:
Keep the spring 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.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 25
hours or yearly to ensure proper performance of your
product. Spark arrestors may be in different locations
depending on the model purchased. Please contact your
nearest service dealer for the location of the spark arrestor
for your model.
Cleaning Instructions:
Remove the spark arrestor from the muffler.
If your spark arrestor is made of a fiberglass material,
discard and replace.
If your spark arrestor is made of a metal material follow
these cleaning instructions:
1. Spray the spark arrestor with a quality carbon
cleaner.
2. Gently clean using a wire brush.
3. Install the new or cleaned spark arrestor and reas-
semble completely before use.
REPLACING AND CLEANING AIR FILTER (FIG. 16 & 17)
For proper performance and long life, keep air filter clean.
1. Remove the air filter cover (44) by pushing down on the latch (22)
with your thumb while gently pulling on the cover (42).
2. Remove the filter (43), clean it in warm soapy water. Rinse
and let dry completely. For best performance, replace
annually.
3. Install the filter, align tabs (41) push in, and make sure
the latches are locked into place.
FUEL CAP
WARNING:
A leaking fuel cap is a fire hazard and must be
replaced immediately.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine perfor-
mance. If performance improves when the fuel cap is
loosened, check valve may be faulty or filter clogged.
Replace fuel cap if required.
SPARK PLUG
This engine uses a Champion RCJ-6Y with 0.63 mm (.025
in.) electrode gap. Use an exact replacement and replace
annually.
STORAGE (1 MONTH OR LONGER)
1. Drain all fuel from tank into a container approved for
fuel. Run engine until it stops.
2. Clean all foreign material from the trimmer. Store it in a
well-ventilated place that is inaccessible to children.
Keep away from corrosive agents such as garden
chemicals and de-icing salts.
4. Abide by all ISO and local regulations for the safe
storage and handling of fuel. Excess fuel should be
used up in other 2-cycle engine powered equipment.
