Two-Stroke Fuel
Fuel is very ammable. Do not smoke or bring any ame or sparks near fuel.
Always stop the engine and allow it to cool before refuelling.
Refuel outdoors on bare ground, restart 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 specications of: API TC, ISO-L-EGC, JASO FC (Low Smoke) oil.
Recommended mixing ratio is 25:1.
FUEL WITH NO OIL (RAW PETROL) will cause severe damage to the engine which is not covered by
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 25 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 muer 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.

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 grass 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.

Original Instructions Version October 13
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
ltered funnel, up to 80% of the fuel tanks capacity.
Replace the fuel cap and tighten securely. Spilled
fuel must be wiped away from the blower before
starting the engine.
Move at least 5m away from the refuelling area before restarting the engine.
When relling the tank, always turn o the engine and allow it to cool down. Take a careful look around
to make sure that there are no sparks or open ames anywhere nearby before refuelling.

Adjusting the Engine Idle Speed
1. Start the engine by following the
procedures described on the preceding
pages.
2. Run the engine at idle speed until
operating temperature is reached (2-3
minutes).
3. Use a screwdriver to adjust the engine
idle speed to 2300-2500r/min.
Turn the idle screw clockwise to increase engine
idle speed.
Turn the idle screw counterclockwise to decrease
engine idle speed.
IMPORTANT !
Machine tubes and intake cover must be installed while adjusting engine idle! Engine idle speed will also be
aected if either the intake cover or machine tubes are blocked, damaged or incorrectly installed!
IMPORTANT !
If the engine continues to run with the ignition switch in the“OFF”position, stop the engine by pulling the
choke control out to the fully closed position.
A clean and unrestricted airow is essential to your machine’s engine performance and durability! Before
attempting any carburetor adjustments, inspect and clean the engine air cleaner as described on page 11 of
this manual.

Using the Machine
As a general rule, try to operate your machine at the lowest throttle setting necessary to get the job done:
• Use low throttle settings when clearing lightweight materials from around lawns or shrubbery.
• Use medium to higher throttle settings to move lightweight grass or leaves from parking lots or walkways.
• Use full throttle when moving heavy loads such as dirt or snow.
Safe operation
(1) Machine noise increases at higher throttle settings. Always use the lowest throttle setting required to get
the job done.
(2) Never operate the blower when visibility is poor.
(3) Always wear eye protection such as face shield or goggles while operating this machine.
(4) Wear a dust mask to reduce the risk of inhalation injuries.
(5) Wear close-tting clothing to protect your legs and arms.
(6) Wear hearing protection when operating this machine.

0.6~0.7mm. Replace any damaged or visibly worn
plug with a NGK BPMR7A or equivalent.
3. Install the spark plug nger-tight in the cylinder
head, and then tighten it rmly with the spark plug
wrench. If a torque wrench is available, torque the
spark plug to 148-165 inch pounds.
Every 50 Hours Use (MORE FREQUENTLY IF YOU NOTE REDUCED PERFORMANCE)
INSPECTION Inspect the entire machine and
tubes for damage, including loose or missing
components, and repair as necessary.
SPARK PLUG Replace the spark plug with a
NGK BPMR7A , gapped to( 0.6~0.7)mm.
FUEL FILTER Use a wire hook to extract the fuel lter
from inside the fuel tank, and then remove and
wash the lter element in clean fuel.
Before reinstalling the lter, inspect the condition
of the fuel line. If damage or deterioration is noted,
the vacuum should be removed from service until
it can be inspected by a trained service technician.
COOLING SYSTEM Remove the engine cover (as described under “Spark Arrestor”), and use a wood or plastic
scraper and a soft brush to remove dirt and debris from the cylinder ns and crankcase.
