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, be certain the muffler gasket tabs (D) are locked into
the muffler grill slots and the stop switch lead is seated in the rubber grommet.
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. Gardenline strongly recommends that you return your hedge trimmer to the address on
the warranty card for this important maintenance service.
