● 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.
High Altitude Adjustment (Level 2)
Fig. 21 +22
Tools required
1 Screwdriver
1 Tachometer
Parts require
None.
High altitude adjustment is not required for proper operation of this engine.
