ADDITIONAL SAFETY RULES FOR PETROL BRUSH CUTTER
WARNING! Beware of kickback.
KICKBACK
Take care using the metal blade with the tool. Kickback is a reaction that
occurs when the blade hits objects that it can not cut. This can make the
blade push away from the object or run along the object. This reaction can be
intense enough to lose control of the tool and can occur without a warning.
The operator should cut from right to left to minimize the chance of kickback.
WARNING! Dress appropriately.

M.
Always use the brush cutter with the shoulder strap.
Do NOT use saw blades. Use only blades designed for use with
brush cutters.
Do not operate with loose clothing or long hair. These can be sucked
into the air intake of the tool.
While using, always wear sturdy footwear and long trousers. Do not
operate the equipment with bare feet or open sandals.
Do not operate in a hazardous location. Such areas include where
there is a risk of explosion of fumes, leaking gas or explosive dust.
Do not operate in a confined area. Exhaust gases, smoke or fumes
could reach dangerous concentrations.
Protect your tool. This tool is NOT WEATHERPROOF and should
not be exposed to direct sunlight, high ambient temperature and
damp, wet or high humidity conditions.
Do not smoke or use a mobile phone while refuelling. This is
potentially dangerous as it may ignite the fuel and cause an
explosion.
Take care not to spill fuel. When refuelling the tool ensure that the
engine has been switched off. Prevent the spilling of fuel as this
may also ignite with the hot engine. Never refuel whilst the engine is
running.
Be careful where you store the tool. Store the tool in a dry area away
from flammable liquids.
Keep your distance. The tool emits exhaust fumes.
Ensure you use fuel oil mix. Ensure that you mix 40 parts unleaded
fuel to 1 part two stroke oil, if not the engine will overheat and cause
damage to your tool.
Never fill fuel tank indoors.

Stop the engine before re-fuelling.
Stop the engine and disconnect the spark plug wire If the tool starts
to vibrate abnormally (find and remove the cause of the vibration
immediately).
Reduce the throttle before turning off the engine.
The user is responsible for the safety of other people, animals and
objects in the working area. Keep people, children and domestic
animals at a safe distance while the tool is in use.

FUEL
USE FRESH UNLEADED FUEL (PETROL), 90 OCTANE OR BETTER – Do
NOT use E10 or Ethanol blends. Mix with a premium grade air cooled 2 stroke
oil at a ratio of 40:1
Mix fuel with 2 stroke oil in an approved container. Shake gently and ensure a
thorough mix.
WARNING! Fuel is very flammable. Use extreme care when mixing,
storing or handling fuel or serious personal injury may result.
CAUTION! Never use raw fuel without oil in your unit. This will cause
permanent engine damage and void the warranty for that product.
Never use a fuel mixture that has been stored for over 90 days.
CAUTION! The 2 stroke oil must be a premium grade oil for 2-cycle
air cooled engines and must be mixed at a 40:1 ratio with the fuel.
Mixing the fuel at a greater ratio than 40:1 provides insufficient
lubrication and will cause engine damage and voids your warranty.

FUELING
WARNING! Always shut off engine before fuelling. Never add fuel to a
machine with a running or hot engine.

●●
Be careful not to spill any mixture. If this
happens, wipe the spill with a clean rag.
●●
Start the engine at least three metres away
from the area where the fuel tank has been
filled up in order to reduce risk of fire.
RUNNING IN THE ENGINE
Fuel Cap
OPERATION
A factory-new machine should run at moderate speed for the first 2-3 hours
of work, as different components need to settle with each other during the
process of running in the engine.
The engine can reach its maximum power after this running in period.
After the first 2-3 hours of works, stop and make sure that all nuts and screws
are securely fastened, and tighten them if necessary.
NOTE. It is normal for smoke to be emitted from a new engine during and
after first use.

WARNING! Read and understand all of the safety warning in this
manual before operating the brush cutter.
WARNING! Beware of kickback.
WARNING! Always position the brush cutter on the operator’s right
hand side when using.
WARNING! The operator must keep at least 15 metres away from
bystanders when using the brush cutter.
USING THE BRUSH CUTTER WITH THE BLADE.
●●
●●
●●
●●
Hold the brush cutter with the right hand on the throttle lever and the
left hand on the left handle.
Keep a firm grip with both hands while in operation. Brush cutter
should be held at a comfortable position with the right 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.
Adjust the shoulder strap to position the brush cutter at a
comfortable operating position and to assure that the shoulder strap
will reduce the risk of operator contact with the blade.
17
●●
●●
●●
Inspect and clear the area of any hidden objects such as glass,
stones, concrete, fencing, wire, wood, metal, etc.
Never use blades near footpaths, fencing, posts, buildings or other
immovable objects.
The brush cutter should be used like a scythe, cutting from the right
to the left in a broad sweeping action.
The blade is suited only for weeds and vines. When the blade
becomes dull, it can be turned over to extend the life of the blade.
Do not sharpen the blade.
USING THE TOOL AS A LINE TRIMMER.
●●
●●
Keep the trimmer tilted toward the area being cut. This is the best
cutting area.
Cut from right to left and from the top down. This reduces the
amount of debris thrown at the operator and reduces the risk of the
entanglement.
NOTE. If grass becomes wrapped around the spool, stop the engine, and
remove the grass.
FEEDING THE LINE
The line trimmer has a bump feed mechanism which releases the line without
having to stop the engine.
●●
To release additional line, lightly tap the line trimmer spool on the
ground while operating the unit at high speed. Never bump the spool
head on concrete as it may crack the spool housing.
NOTE. Always keep the line fully extended. Line release becomes more
difficult as the cutting line becomes shorter. Each time the line trimmer spool is
bumped it releases approximately 2cm of line. Release the line until it strikes
the line cutting blade. This may require several taps.
