OPERATION
■ It has been reported that vibrations from hand-held
tools 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.
There are measures that can be taken by the operator
to possibly reduce the effects of vibration:
■ 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.
■ After each period of operation, exercise to increase
blood circulation.
■ Take frequent work breaks. Limit the amount of
exposure per day.
■ Injuries may be caused, or aggravated by prolonged
use of a tool. When using any tool for prolonged
periods, ensure you take regular breaks.
■ If you experience any of the symptoms of this
condition, immediately discontinue use and see your
doctor about these symptoms.
OPERATING AS A LINE TRIMMER (FIG.6)
Follow these steps to operate the straight shaft trimmer.
■ Start the trimmer.
■ Hold the trimmer at waist level with your right hand
on the trigger handle and your left hand on the front
handle.
8
■ Place the product on the right side of your body with
the engine behind and away from your body.
■ Trim grass and weeds in a left-to-right motion with the
line parallel to the ground.
TO ADVANCE THE CUTTING LINE (FIG.7)
Follow these steps to advance the cutting line.
■ Start the trimmer.
■ Tap the bump knob lightly on the ground while the
motor is running. The line will only advance with the
engine at full throttle. Do not hold the bump knob on
the ground.
■ Do not bump the knob on hard surfaces such as
concrete. This may cause damage to the bump knob.
Note:
The line cutting blade on the safety guard will
cut the line to the proper length.
Note:
To help prevent line tangle, tap only once to
lengthen the line. If additional line is required, wait a
few seconds before retapping the bump knob. Do not
allow the line to wear too short. Keep the cutting line
at full length.
OPERATING AS A BRUSHCUTTER (FIG. 8-9)
WARNING
Extreme care must be taken when using blades to
ensure safe operation. Read the safety information for
safe operation using the blade, refer to “Specific Safety
Rules for Brushcutter and Blade Use” earlier in this
manual.
TRI-ARC BLADE
The TRI-ARC blade is suited only for pulpy weeds and
vines. When the blade becomes dull, it can be turned over
to extend the life of the blade. Do not sharpen the TRI-
ARC blade.
Hold the brushcutter with the right hand on the trigger
handle and the left hand on the front handle. Keep a firm
grip with both hands while in operation. Brushcutter should
be held at a comfortable position with the trigger handle
about hip height. Maintain your grip and balance on both
feet. Position yourself so that you will not be drawn off
balance by the kick-back reaction of the cutting blade. If
using a shoulder strap adjust to position the brushcutter
at a comfortable operating position. Shoulder straps
are available as an accessory and may help to reduce
operator fatigue.
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction which may occur when
the spinning blade contacts anything it cannot cut. This
contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was
hit. This reaction can be violent enough to cause the
operator to lose control of the unit. Blade thrust may occur
without warning if the blade snags, stalls or binds. This is
more likely to occur in areas where it is difficult to see the
material being cut. For cutting ease and safety, approach
the weeds being cut from the right to the left. In the event
that an unexpected object or woody stock is encountered,
this could cause the blade thrust reaction.
MAINTENANCE
WARNING
When servicing, use only original manufacturer's
replacement parts. Use of any other parts may create a
hazard or cause product damage.
WARNING
Always wear safety goggles or safety glasses with side
shields during tool operation. If operation is dusty, also
wear a dust mask.
WARNING
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug lead and move it away from
spark plug. Failure to follow these instructions can
result in serious personal injury or property damage.
WARNING
Neglected or poorly conducted maintenance may
create additional hazards. Do not attempt to repair or
maintain this product if you are not qualified to do so.
If in doubt, return to a service centre for professional
assistance.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, lubricant, grease.
WARNING
Do not at any time let brake fluids, petrol, petroleum-
based products, penetrating lubricants, etc., come
in contact with plastic parts. Chemicals can damage,
weaken or destroy plastic which may result in serious
personal injury.
You can often make adjustments and repairs described in
9
this manual. For other repairs, have the trimmer serviced
by an authorised service dealer.
CLEANING THE AIR FILTER (FIG. 11)
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the engine.
Check the air filter monthly. For best performance, replace
the air filter at least once a year.
■ Loosen the air filter cover by turning the cover securing
knob (item 22) counterclockwise.
■ Remove the air filter (item 20).
■ Clean the foam filter element with warm soapy water.
Rinse and let dry.
NOTE:
If the foam filter element is damaged, it should be
replaced.
■ Apply a light coat of engine oil to the foam filter
element, then squeeze it out.
■ Reinstall the air filter.
NOTE:
Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
■ Reinstall the cover and tighten knob to secure.
CHECKING THE FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and
check valve. A clogged fuel filter causes poor engine
performance. If performance improves when the fuel cap
is loosened, the check valve may be faulty or the filter may
be clogged. Replace the fuel cap if necessary.
REPLACING THE SPARK PLUG (FIG. 12)
This engine uses a Champion RCJ4 / RCJ6Y or NGK
BPMR7A spark plug. Use an exact replacement and
