Maintenance and care
• If you have any questions or problems, please contact your ECHO dealer.
Cleaning air fi lter
NOTE
If fi lter is excessive dirty or no longer fi ts properly, replace it.
• Close choke.
Release the cleaner cover latch, and remove air cleaner cover.
• Remove air fi lter.
• Brush off dust lightly, or wash them in a non-infl ammable solvent if necessary, or
replace the air fi lters.
Do not wash the felt air fi lter.
• Dry them completely before installation.
• Reinstall air fi lters and cover, and engage latch.
Check fuel system
• Check before every use.
• After refuelling, make sure fuel does not leak or exude from around fuel pipe, fuel
grommet or fuel tank cap.
• In case of fuel leakage or exudation there is a danger of fi re.
Stop using the machine immediately and request your dealer to inspect or replace.
Replacing fuel fi lter
• Use a piece of steel wire or the like to pick up fuel fi lter through fuel tank opening.
• Pull old fi lter from fuel line.
• Install new fuel fi lter.
Check spark plug
• Check plug gap.
Correct gap is 0.6 to 0.7 mm.
• Inspect electrode for wear.
• Inspect insulator for oil or other deposits.
• Replace plug if needed and tighten to 15 - 17 N•m (150 to 170 kgf•cm).
Cooling system maintenance
IMPORTANT
To maintain proper engine operating temperature, cooling air must pass
freely through the cylinder fi n area.
This fl ow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching the cylinder,
or
• Dust and grass build up on the out side of the cylinder.
This build-up insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cylinder fi ns is
considered “Normal Maintenance”.
Any resultant failure attributed to lack of maintenance is not warranted.
• Remove dust and dirt from between fi ns.
• Before each use, remove accumulated debris from bottom engine intake grille
located between the fuel tank and starter.
