Original instructions | English
■ Any part that is damaged should be properly repaired or
replaced by an authorised service centre.
■ Check all nuts, bolts, and screws at frequent intervals
for proper tightness to ensure the product is in a safe
working condition.
RESIDUAL RISK
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
■ Injury caused by vibration
– Hold the product by designated handles and restrict
working time and exposure.
■ Exposure to noise can cause hearing injury
– Wear hearing protection and limit exposure.
■ Eye injury due to flying debris
– Wear eye protection at all times.
RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome.
Symptoms may include tingling, numbness and blanching
of the ngers, 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 product, 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.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
Wear eye, hearing, and head protection
when operating the product.
Beware of thrown or ying objects. Keep
all bystanders, especially children and
pets, at least 15 m from the operating
area.
Wear non-slip safety footwear when
using the product.
Wear non-slip, heavy duty gloves.
Do not use blade(s) on the product.

with clean water. If irritation is still present, see a
physician immediately.
■ Clean up spilled petrol immediately.
Mixing the fuel
■ The product is powered by a 2-stroke engine and
requires pre-mixing petrol and 2-stroke oil. Store premix unleaded petrol and 2-stroke engine oil in a clean
container approved for petrol.
■ This engine is certified to operate on unleaded petrol
intended for automotive use with an octane rating of 91
([R + M] / 2) or higher.
■ Do not use any type of pre-mixed petrol / oil from fuel
service stations, this includes the pre-mixed petrol / oil
intended for use in mopeds, motorcycles, etc.
■ Use synthetic 2-stroke oil only. Do not use automotive
oil or 2-stroke outboard oil.
■ Mix 2% synthetic 2-stroke oil into the petrol. This is a
50:1 ratio.
■ Mix the fuel thoroughly and also each time before
fuelling.
■ Mix in small quantities. Do not mix quantities larger
than usable in a 30 day period. Synthetic 2-stroke oil
containing a fuel stabilizer is recommended.
Filling the tank
■ Clean the surface around the fuel cap to prevent
contamination.
■ Loosen the fuel cap slowly to release pressure and to
keep fuel from escaping around the cap.
■ Carefully pour the fuel mixture into the tank. Avoid
spillage.
■ Prior to replacing the fuel cap, clean and inspect the
gasket.

side of the PRO-CUT I fixed line head.
■ Pull the line outwards so it is tight and even on both
sides of the spool.
■ Install the PRO-CUT I head assembly on the drive shaft
and then secure with spool retainer.
CLEANING THE AIR FILTER
A dirty air lter will cause starting difculty, loss of
performance, and shorten the life span of the engine.
Check the air lter monthly. For best performance, replace
the air lter at least once a year.
■ Stop the engine.
■ Remove the air filter cover by pushing down on the
latch with your thumb while gently pulling on the cover.
■ Remove the air filter.
■ 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.
■ Replace the air filter cover by inserting the slot at the
bottom of the air box cover into the latch at the bottom
of the air box base; push the air box cover up until it
latches securely in place.
WARNING
Make sure the trimmer head stops rotating when you
release the trigger. Contact with a rotating trimmer head
could cause personal injury.
CHECKING THE FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must be replaced
immediately.
REPLACING THE SPARK PLUG
This engine uses a TORCH L7RTC spark plug. Use an
exact replacement and replace annually.
Follow these steps to replace the spark plug.
■ Stop the engine.
■ Remove the spark plug boot.
■ Loosen the spark plug by turning it counterclockwise
with a combination wrench.
■ Remove the spark plug.
■ Hand thread the new spark plug, turning it clockwise.
■ Tighten with a combination wrench to 22~25 Nm torque
or at least 4 turns after finger tight. Do not overtighten.
CAUTION
Be careful not to cross-thread the spark plug. Crossthreading will seriously damage the engine.
CLEANING THE EXHAUST HOLE OF THE CYLINDER
AND INTAKE HOLE OF THE MUFFLER
CAUTION
Always stop the engine and allow it to cool down before
cleaning the exhaust hole.
Make sure the product is in the "off" position.
■ Remove the screws on the top and rear portions of the
housing counterclockwise.
■ Remove the rear housing from the engine.
■ Remove the muffler screws counterclockwise, and then
remove the muffler cover, muffler, and gasket from the
cylinder.
■ Use the brush to clean the exhaust hole of the cylinder
and intake hole of the muffler.

back to its position. Tighten the screws by turning it
clockwise.
■ Place the rear housing back to its position. Tighten the
screws by turning it clockwise.
The fuel cap contains a non-serviceable lter and a check
valve. A clogged fuel lter causes poor engine performance.
If performance improves when the fuel cap is loosened, the
valve may be faulty or the lter may be clogged. Replace
the fuel cap if necessary.
SPARK ARRESTOR
