SERVICE AND ADJUSTMENT
WARNING: Before you inspect, clean or service the machine, stop the engine.
Make sure that all moving parts have stopped. Disconnect the wire from the
spark plug.
HOW TO REPLACE THE TRIMMER LINE
For the best performance, use a heavy
gauge 3.3mm (0.130” diameter) trimmer
line. Cut the length of the trimmer line to
52cm (21.5 inches). Do not allow the length
of the lines to vary more than one inch. This
is important to make sure the trimmer head
is balanced and does not vibrate.
IMPORTANT: To extend the life of the trim-
mer line, keep the trimmer line moist. If not
kept moist, the nylon trimmer line will be-
come dry and brittle. Keep extra trimmer
line in a can of water. The line will then stay
flexible and easy to change. A flexible line
will also last much longer.
HOW TO CHANGE TRIMMER LINES
When the trimmer line becomes worn to half the original length, replace the trimmer line as
follows:
1. Stop the engine. Wait for
all moving parts to stop.
2. Remove worn trimmer
line from line retainer.
3. First, thread the ends of
the new trimmer line
through the outside
loops.

line are even.
