may contribute to a condition called Raynaud’s Syndrome in certain individuals. Symptoms may include
tingling, numbness and blanching of the fingers, usually
apparent upon exposure to cold. Hereditary factors,
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) Keep your body warm in cold weather. When operating the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major
factor contributing to Raynaud’s Syndrome.

MIXING THE FUEL
■ This product is powered by a 2-cycle engine and requires
pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded
gasoline and 2-cycle engine oil in a clean container
approved for gasoline.
■ This engine is certified to operate on unleaded gasoline
intended for automotive use with an octane rating of 87
([R + M] / 2) or higher.
■ Do not use any type of pre-mixed gasoline/oil from fuel
service stations, this includes the pre-mixed gasoline/oil
intended for use in mopeds, motorcycles, etc.
■ Use high a quality 2-cycle self mixing oil for air cooled
engines. Do not use automotive oil or 2-cycle outboard
oil.
■ Mix 2% oil into the gasoline. This is a 50:1 ratio.
■ Mix the fuel thoroughly and also each time before
fueling.
■ Mix in small quantities. Do not mix quantities larger than
usable in a 30 day period. A 2-cycle oil containing a fuel
stabilizer is recommended.

OPERATING THE TRIMMER
See Figure 5.
Hold the trimmer with the right hand on the rear handle and
the left hand on the front handle. Keep a firm grip with both
hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around
the driveshaft housing and string head which may cause
damage from overheating. If grass becomes wrapped
around the string head, stop the engine, disconnect the
spark plug wire, and remove the grass. Prolonged cutting at
partial throttle will result in oil dripping from the muffler.
FILLING THE TANK
1. Clean surface around fuel cap to prevent contamination.
2. Loosen fuel cap slowly to release pressure and to keep
fuel from escaping around the cap.
3. Carefully pour fuel mixture into the tank. Avoid spillage.
4. Prior to replacing the fuel cap, clean and inspect the
gasket.
5. Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage. Move 9 m (30 ft.) away from refueling
site before starting engine.
NOTE: It is normal for smoke to be emitted from a new
engine during and after first use.

OPERATION
ADVANCING THE STRING
GRASS DEFLECTOR LINE TRIMMING CUTOFF BLADE
ADVANCING STRING USING THE EZ LINE™ TAP
ADVANCE SYSTEM
String advance is controlled by tapping string head on grass
while running engine at full throttle.
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. Resume trimming.
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
THE ENGINE, and manually advance the string.
See Figure 7.
This trimmer is equipped with a line trimming 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 hear the engine running faster than normal.
This will maintain best performance and keep string long
enough to advance properly.
ADVANCING THE STRING MANUALLY
Push the spool retainer down while pulling on string(s) to
manually advance the string.
CUTTING TIPS
See Figure 6.
■ 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
wear string rapidly.
■ Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
string.
