Maintenance
SPARK ARRESTER (MA4)
• The muffler is equipped with a
spark arrester to prevent red hot
carbon from flying out of the
exhaust outlet.
Periodically inspect and clean as
necessary with a wire brush.
In the State of California it is
required by law (Section 4442 of the
California Public Resources Code) to
equip a spark arrester when a gas
powered tool is used in any forest
covered, brush covered, or grass
covered unimprovedland.
(1) Spark arrester
INTAKE AIR COOLING VENT
WARNING
• Never touch the cylinder, muffler,
or spark plugs with your bare hands
immediately after stopping the
engine. The engine can become
very hot when in operation, and
doing so could result in severe
burns.
• Clean the cylinder fins with
compressed air or a brush. (MA5)
(1) Cylinder
(2) Intake air cooling vent (back)
IMPORTANT
• If waste gets stuck and causes
blockage around the intake air
cooling vent or between the
cylinder fins, it may cause the
engine to overheat, and that
in turn may cause mechanical
failure on the part of the hedge -
trimmer.
BLADES
Oil blades each gas tank filling.
(MA6)
WARNING
• Make sure that the blade bolts are
well tightened.
• The blade assembly is designed to
automatically compensate for any
play between the blades.
Sharpening (MA7)
Always keep the file or sharpener at
an
angle of 45° to the blade, and:
• Always grind in the direction of
the cutting edge;
• Note: files cut only in one
direction; lift
the file from the blade when
returning to start a new pass;
• Remove all burr from the edge of
the blade with a slip stone;
• Remove as little material as
possible;
• Before refitting the sharpened
blades, remove filings and then apply
grease.
Do not try to sharpen a damaged
blade: change it or take it to a
Service dealer.
REDUCTION GEARBOX
Refill gear housing every 25 working
hours. Use greese pump. Feed
greese until itcomes out of the base
of blades. (MA8)
PROCEDURES TO BE PERFORMED
AFTER EVERY 100 HOURS OF USE
1. Remove the muffler, insert a
screwdriver into the vent, and wipe
away any carbon buildup. Wipe away
any carbon buildup on the muffler
exhaust vent and cylinder exhaust
port at the same time.
2. Tighten all screws, bolts, and
fittings.
3. Check to see if any oil or grease
has worked its way in between the
clutch, lining and drum, and if it has
wipe it away using oil - free, lead - free
gasoline.
