■Ithas been reportedthat vibrations fromhand-held tools
may contribute to a condition called Raynaud’s Syn-
drome in certain individuals. Symptoms may include
tingling, numbness and blanching of the fingers, usually
apparentuponexposuretocold. Hereditaryfactors,
exposure to cold and dampness, diet, smoking and work
practices are all thought to contribute to the development
of these symptoms. It is presently unknown what, if any,
vibrations or extent of exposure may contribute to the
condition. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
a) Keepyour bodywarmincoldweather.Whenoperat-
ing the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major
factorcontributingtoRaynaud’s Syndrome.
IMPORTANT SAFETY INSTRUCTIONS
b) After each period of operation, exercise to increase
bloodcirculation.
c) Take frequent work breaks. Limit the amount of
exposureperday.
d) Keepthetoolwellmaintained, fasteners tightened
andwornpartsreplaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician
about these symptoms.

ADVANCING THE STRING
ADVANCING STRING USING THE EZ LINE™ TAP
ADVANCE SYSTEM
String advance is controlled by tapping string head on grass
whilerunning engine atfullthrottle.
1. Run engine at full throttle.
2. Tap string head on ground to advance string. String
advances each time the head is tapped.
3. Several taps may be required until string strikes the cut
off blade.
4. Resumetrimming.
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
THEENGINE, and manually advance thestring.
ADVANCING THE STRING MANUALLY
Pushthe spoolretainer down whilepulling on string(s) to
manuallyadvance thestring.
CUT OFF BLADE
This trimmer is equipped with a cut-off blade on the grass
deflector. For best cutting, advance string until it is trimmed
to length by the cut-off blade. Advance string whenever you
hearthe engine running fasterthannormal.This willmain-
tainbest performance andkeep string longenoughto
advance properly.
CUTTING TIPS
See Figure 9.
■Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
■Do not cut in dangerous cutting area.
■Use the tip of string to do the cutting; do not force string
head into uncut grass.
■Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wearstringrapidly.
■Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
string.

mance. If performance improves when the fuel cap is
loosened, check valve may be faulty or filter clogged.
Replacefuel cap ifrequired.
SPARK PLUG
This engine uses a NSK # BPMR7A spark plug with
.025 in. (0.63 mm) electrode gap. Usean exactreplace-
ment and replace annually, or more frequently if necessary.

1. To check for spark: Disconnect the spark plug
wire. Reattach the spark plug wire and lay spark
plug on metal cylinder. Pull the starter rope and
watch for spark at spark plug tip. If there is no
spark, repeat test with a new spark plug.
2. Push primer bulb until bulb is full of fuel. If
bulb does not fill, primary fuel delivery system
is blocked. Contact a service dealer. If primer
bulb fills, engine may be flooded (see next

3. Remove spark plug, turn trimmer so spark plug
hole is aimed at the ground. Move choke lever
to “RUN” and pull starter cord 10 to 15 times.
This will clear excess fuel from engine. Clean
