Original Instructions Version June13
266LRH / 268LRH Hedgetrimmer
Never hold the hedge trimmer in a way in which the blades are pointing towards someone else.
Never allow the blades to come into contact with your body.
Always turn off the engine before adjusting the hedge trimmer, removing branches which have become
stuck in the blades, or at any other time when coming into close proximity with the blades.
Always wear thick work gloves when adjusting the hedge trimmer.

Falling branches may fall onto the operator’s body or head, resulting in injuries, scratches, and cuts, and for
this reason you should always wear a helmet when operating the hedge trimmer.
Safe Handling of Fuel
The engine of the hedge trimmer is designed to run on a two-stroke oil/fuel mixture. This fuel is highly
flammable, never store cans of fuel or refill the fuel tank in any place where there is a source of heat or fire
which might ignite the fuel.
Do not smoke whilst operating the hedge trimmer or refilling, keep lit cigarettes away from the hedge
trimmer at all times.
When refilling the fuel tank always stop the engine first and carefully make sure that there are no sparks or
open flames anywhere nearby before refuelling.
If any fuel spillage occurs during refuelling, use a dry rag to wipe any fuel which has been spilled onto the
hedge trimmer before starting the engine.
After refuelling, screw the fuel cap back tightly onto the fuel tank and carry the hedge trimmer to a spot 5
metres or more away from where it was refuelled before starting the engine.

Before Operating the Hedge Trimmer
Before beginning work, carefully check the work area and remove any obstacles.
Within a perimeter of 15 metres of the work area should be considered a hazardous area into which no-one
should enter while the hedge trimmer is being used, and when necessary this area should be marked with a
warning rope, warning signs, or other forms of warning.
When work is to be performed simultaneously by two or more operators, care should also be taken to
constantly look around to check the presence and locations of other operators within the work area to
maintain a safe distance between each operator.
Before beginning work, each component of the hedge trimmer should be checked to make sure that it is
in proper working order, make sure that there are no loose screws or bolts, fuel leaks, ruptures, dents, or any
other problems which might interfere with safe operation. Be especially careful to check that there is no
damage to the blades.
Keep all parts of your body away from the hedge trimmer blades when the engine is running.
Before Starting the Engine
Carefully check the work area to make sure that no obstacles exist within a perimeter of 15 metres around
the hedge trimmer before starting the engine.
To start the engine, place the hedge trimmer onto the ground in a flat clear area and hold it firmly in place to
ensure that neither the blades or the throttle come into contact with any obstacles when the engine starts.
After starting the engine, make sure that the blades stop moving when the throttle trigger is released (idle).
If the blades continue to move when the engine is at idle, adjust the idle screw on the carburettor to a
point where the blades stop moving, if this cannot be achieved, take the hedge trimmer to your authorised
servicing dealer for adjustment.

Avoid Noise Problems
Check and follow the local regulations for sound levels and hours of operation for garden machinery.
In general, operate hedge trimmers between 8 am, and 5 pm on week days and 9 am to 5 pm at weekends.
Avoid using the hedge trimmer late at night and/or early in the morning.
Safety when using the Hedge Trimmer
When using the hedge trimmer, grip the handles firmly with both hands, place your feet slightly apart so
your weight is distributed evenly across both legs, and always maintain a steady even posture while working.
Do not use on ladders or if the ground surface is slippery or uneven. Never attempt to cut directly overhead
or with one hand.
•
•
•
•
•
Maintain full engine speed when cutting.
Never allow other persons to come within the work area as doing so might expose them to danger.
Keep work area clear of all persons, particularly small children and pets. Injury may result from flying debris.
If a branch or other object gets caught in the hedge trimmer during operation, always stop the engine before removing the object.
To protect yourself against injury from falling branches, wear the required safety equipment.
•
Never touch the spark plug or plug HT cable while the engine
is in operation, doing so may result in an electrical shock.
•
Never touch the exhaust, spark plug, or any metallic parts
while the engine is in operation or immediately after shutting
down the engine. These parts reach high temperatures during
operation and doing so could result in serious burns.
•
When you finish cutting in one location and wish to continue work in another area, stop the engine, place the protective cover over the blades, and turn the hedge trimmer so that the blade faces behind your body before carrying it to the new location.
Always remove fuel from the fuel tank before transportation to prevent fuel spillage.
Never leave the hedge trimmer exposed to direct sunlight as this can heat the fuel tank and may cause a discharge of fuel, and flood the engine.

Two-Stroke Fuel
Fuel is very flammable. Do not smoke or bring any flame or sparks near fuel. Always stop the engine and
allow it cool before refuelling. Refuel outdoors on bare ground, restart the engine at least 5m away from the
refuelling stop.
The engine is lubricated by oil mixed into petrol. Prepare a mixture of unleaded petrol and semi-synthetic
two-stroke oil that meets the specifications of: API TC, ISO-L-EGC, JASO FC (Low Smoke) oil.
Recommended mixing ratio is 40:1.
FUEL WITH NO OIL (RAW PETROL) will cause severe damage to the engine which is not covered by
the manufacturer’s warranty.
Use fresh, unleaded petrol (95 RON) and semi-synthetic oil specially made for high performance two-stroke
engines. Mix in a ratio of 40 parts petrol to 1 part of oil.
By using two-stroke oil specially made for two-stroke engines you will reduce the formation of ash and
carbon deposits on the spark plug, piston, exhaust muffler and cylinder as well as reducing emissions of
harmful exhaust gases.
Oil FOR 4-CYCLE ENGINES should not be used as two stroke lubrication oil as it can cause fouling of the spark
plug, exhaust port blocking, piston ring sticking and other internal engine damage.

Original Instructions Version June13
266LRH / 268LRH Hedgetrimmer
Fuel Storage
Mixed two-stroke fuel which has been left unused for a period of one month or more may damage
the carburettor and result in the engine failing to start or operate correctly.
When storing the hedge trimmer for a period of more than one month, empty the fuel tank, and
run the engine to empty the carburettor of fuel.
Two stroke fuel can cause deterioration of rubber and/or plastic components during prolonged
storage.
It is important to only use good quality, fresh fuel mix.
Fuelling
Shake the fuel container to thoroughly mix the two-stroke oil and petrol.
Clean dirt from around the fuel cap before removing.
Pour two-stroke fuel into the fuel tank with a filtered funnel, up to 80% of the fuel tanks capacity.
Replace the fuel cap and tighten securely. Spilled fuel must be wiped away from the hedge
trimmer before starting the engine.
Move at least 5m away from the refuelling area before restarting the engine.
When refilling the tank, always turn off the engine and allow it to cool down. Take a careful look around to make sure that there are no sparks or open flames anywhere nearby before refuelling.
