Vibration and cold
It is believed that a condition called Raynaud's Phenomenon which affects the fingers of certain individuals may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning,
followed by loss of colour and numbness in the fingers.
The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.
Keep your body warm, especially the head and neck,
feet and ankles, and hands and wrists.
Maintain good blood circulation by performing vigorous
arm exercises during frequent work breaks, and also by
not smoking.
Limit the number of hours of operation.
Try to fill each day with jobs where operating the hedge
trimmer or other hand-held power equipment is not required.
If you experience discomfort redness and swelling of
the fingers, followed by whitening and loss of feeling,
consult your physician before exposing yourself further
to cold and vibration.
Failure to observe these instructions could result in damage
to your health.
Repetitive stress injuries
It is believed that over-using the muscles and tendons of
the fingers, hands, arms and shoulders may cause soreness, swelling, numbness, weakness and extreme pain to
the areas just mentioned. Certain repetitive hand activities
may put you at a high risk for developing a repetitive
stress injury (RSI).
To reduce the risk of RSI, do the following:
Avoid using your wrist in a bent, extended or twisted
position.
Take periodic breaks to minimize repetition and rest
your hands. Reduce the speed and force in which you
do the repetitive movement.
Do exercises to strengthen hand and arm muscles.
See a doctor if you feel tingling, numbness or pain in
your fingers, hands, wrists or arms. The sooner RSI is
diagnosed, the more likely permanent nerve and muscle
damage can be prevented.
Failure to observe these instructions could result in damage
to your health.

Hedge and shrub trimming operation
Hedge and shrub trimming operation
Basic hedge trimming operation
NOTE
This product is designed to cut shrubs and hedges with branches no larger than 6 mm in diameter.
When starting to trim, run the engine at full throttle. Cutting at less at than full speed can damage the clutch by allowing it to
slip. When you do not conduct trimming or cutting work, do not run the engine at full throttle.
Pulling the throttle trigger after the engine is started will cause
the engine speed to rise and the cutter blades to start moving.
Adjust the engine speed depending on, for example, the
amount of the hedges to be cut.
1. Throttle trigger
2. High speed
3. Idling
1. Hold trimmer firmly and squeeze throttle trigger to accelerate
engine.
2. Tilt trimmer so cutting teeth are angled slightly toward the
hedge or shrub and proceed to cut.
WARNING
Never remove hands from unit when blades are moving.
The engine continues running even when the blades
have stopped due to an obstruction. If this occurs, stop
the engine, disconnect ignition cable and remove the
obstruction.
Failure to do so could lead to an injury or serious accident,
or cause a fire.

Carburettor adjustment
WARNING
When carburettor adjustment is completed, cutting attachment should not move at idle, otherwise serious personal injury may result.
CAUTION
When starting, idle speed adjuster (T) should be adjusted not to rotate the cutting attachment.
When there is some trouble with the carburettor, contact your dealer.
Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start engine and run several minutes to bring it to operating temperature.
To adjust the carburettor proceed as follow:
Turn "idle" speed adjustment screw (T) clockwise until cutting
atttachment begins to turn, then turn screw(T) out anticlockwise until cutting attachment stops turning. Turn screw (T)
out, anticlockwise, and additional 1 turn.
T: Idle speed adjustment screw
Cleaning cylinder fins
IMPORTANT
To maintain proper engine operating temperature, cooling air must pass freely through the cylinder fin area. This flow
of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
Air intakes are blocked, preventing cooling air from reaching the cylinder,
or
Dust and grass build up on the out side of the cylinder. This build-up insulates the engine and prevents the heat from
leaving.
Removal of cooling passage blockages or cleaning of cylinder fins is considered "Normal Maintenance". Any resultant
failure attributed to lack of maintenance is not warranted.
21
Maintenance and care
1. Cylinder fins 2. Air intake
Cleaning silencer
Remove dust and dirt from between fins.
Before each use, remove accumulated debris from bottom en-
gine intake grille located between the fuel tank and starter.
