Fuel filter (Level 1)
Fig. 11 + 12
Tools required:
1 Length of wire with one end bent into a hook, 200-250 mm
(8-10")
1 Clean rag
1 Funnel
1 A approved fuel container
Parts required:
1 Air & fuel filter kit
Warning! Fuel is very flammable. Use extreme care
when mixing, storing or
handling.
● Use a clean rag to remove loose dirt from around fuel cap and
empty fuel tank.
● Use the fuel line hook to pull the fuel line and filter from the
tank.
● Remove the filter from the line and install the new filter.
Spark plug (Level 2)
Fig. 13 + 14
Tools required:
1 T-wrench
1 Feeler gauge
1 Soft metal brush
Parts required:
1 Tune-up kit
Important: Use a TORCH L9T spark plug (Or equipment like:
NGK BPMR7A, or CHAMPION RCJ6Y), otherwise severe
engine damage may occur.
● Remove spark plug and check for fouling, worn and rounded
center electrode.
● Clean the plug or replace with a new one. Do not sand blast to
clean. Remaining
sand will damage engine.
● Check and adjust spark plug gap by bending outer electrode.
● Tighten spark plug to 150-170 kg/cm (130-150 inch/lb.).
Cooling system (Level 2)
Fig. 15 - 20
Tools required:
1 Screw driver
1 Cleaning brush, 25 mm or 50 mm (1 or 2)
Parts required:
None if you are careful.
Important: To maintain proper engine operating temperatures,
cooling air must pass freely through the cylinder fin area. This
flow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes in the crankcase are blocked, preventing cooling air
from reaching the
cylinder.
• Dust and grass build up on the outside of the cylinder. This
build up insulates the
engine and prevents the heat from leaving. Removal of
crankcase cooling passage
blockages or cleaning of cooling fins is considered Normal
maintenance. Any
failure attributed to lack of maintenance is not warranted.
When overheating and engine seizure occurs do the following:
• Remove spark plug lead and spark plug cap..
• Remove screw (F) from the cylinder cover.
• Remove bottom right (G) and bottom left (G) screws from
cylinder cover.
• Carefully pull cylinder cover forward, pull ignition lead and
flameout lead
and lay aside.
• Loosely install spark plug cap to keep debris out of the
cylinder. Use brush to remove dirt from cylinder fins.
Important: Do not use a metal scraper to remove dirt from the
cylinder fins.
• Assemble components in reverse order.
Note: When installing the cylinder cover, the stop switch lead is
seated in the rubber
grommet.
Engine problems due to inadequate lubrication caused by failure
to use an ISOLEGD and J.A.S.O. FC certified oil will void the
two-stroke engine warranty. (Emission related parts only are
covered for two years, regardless of two stroke oil used, per the
statement listed in the Emission Defect Warranty Explanation.)

Handling Fuel
Warning! Fuel is very flammable. Use extreme care
when mixing, storing or
handling or serious personal injury may result.
● Use an approved fuel container.
● Do not smoke near fuel.
● Do not allow flames or sparks near fuel.
● Fuel tanks/cans may be under pressure. Always loosen fuel
caps slowly allowing
pressure to equalize.
● Never refuel a hedge trimmer when the engine is hot or
running!
● Do not fill fuel tanks indoors. Always fill fuel tanks outdoors
over bare ground.
● Do not overfill fuel tank. Wipe up spills immediately.
● Securely tighten fuel tank cap and close fuel container after
refueling.
● Inspect for fuel leakage. If fuel leakage is found, do not start or
operate hedge
trimmer until leakage is repaired.
● Move at least 3m (10 ft.) from refueling location before starting
Cylinder Exhaust Port (Level 3)
Important: The cylinder exhaust port must be inspected and
cleaned of excess carbon every 3 months or 90 hours of
operation in order to maintain this engine within the emissions
durability period. We strongly recommends that you return your
hedge trimmer to the address on the warranty card for this
important maintenance service.
Engine Break-In
New engines must be operated a minimum duration of two tanks
of fuel break-in before carburetor adjustments can be made.
During the break-in period your engine performance will
increase and exhaust emissions will stabilize. Idle speed can be
adjusted as required.
