It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaudʼs Syn-
drome 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 develop-
ment 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 operat-
ing the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major
factor contributing to Raynaudʼs Syndrome.
b) After each period of operation, exercise to increase
blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
Keep the tool well maintained, fasteners tightened
and worn parts replaced.
Mix and store fuel in a container approved for fuel.
Mix fuel outdoors where there are no sparks or flames.
Wipe up any fuel spillage. Move 9 m away from
refueling site before starting engine.
Stop the engine and allow to cool before refueling or
storing the unit.
Allow the engine to cool; empty the fuel tank and secure
the unit from moving before transporting in a vehicle.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician
about these symptoms.

OPERATING THE TRIMMER (FIG. 5)
Hold the trimmer with the right hand on the
trigger handle and the left hand on the left handle. Keep a
firm grip with both hands while in operation. Trimmer should
be held at a comfortable position with the trigger 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 shaft housing and bump head which may cause damage
from overheating. If grass becomes wrapped around the
bump 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.
ADVANCING THE LINE
ADVANCING LINE USING THE EZ LINE™ TAP
ADVANCE SYSTEM
Line advance is controlled by tapping the bump knob on grass
while running engine at full throttle.
1. Run engine at full throttle.
2. Tap bump knob on the ground to advance line. Line
advances each time the head is tapped.
3. Several taps may be required until line strikes the cut
off blade (49).
4. Resume trimming.
NOTE: If the line is worn too short you may not be able to
advance the line by tapping it on the ground. If so, STOP
THE ENGINE, and manually advance the line.
ADVANCING THE LINE MANUALLY
Push the spool bump knob while pulling on both lines to
manually advance the line.
CUTTING TIPS (FIG. 6)
Keep the trimmer tilted toward the area being cut; this is
the best cutting area (24).
Do not cut in dangerous cutting area (23).
MIXING THE FUEL
This product is powered by a 2-stroke engine and requires
pre-mixing petrol and 2-stroke oil. Pre-mix unleaded petrol
and 2-stroke engine oil in a clean container approved
for fuel.
