Maintenance and care

Œ

If you have any questions or problems, please contact your ECHO dealer.

Cleaning air filter

1. Air cleaner cover. 

2. Air filter.

Œ

Close choke and remove air cleaner cover.

Œ

Remove air filter (air filter is located inside air cleaner cover).

Œ

Brush dirt from filter or wash it in a suitable cleaner.

Œ

Dry it completely before installation.

Œ

Reinstall the air filter and cover.

Check fuel system

Œ

Check before every use.

Œ

After refuelling, make sure fuel does not leak or exude from around fuel pipe, fuel grommet 
or fuel tank cap.

Œ

In case of fuel leakage or exudation there is a danger of fire.
Stop using he machine immediately and request your dealer to inspect or replace.

Replacing fuel filter

1. Fuel filter. 

2. Fuel line.

Œ

Use a piece of steel wire or the like to pick up fuel filter through fuel tank opening.

Œ

Pull old filter from fuel line.

Œ

Install new fuel filter.

Check spark plug

Spark plug gap: 0.6 to 0.7 mm

Œ

Check plug gap.

Œ

Correct gap is 0.6 to 0.7 mm.

Œ

Inspect electrode for wear.

Œ

Inspect insulator for oil or other deposits.

Œ

Replace plug if needed and tighten to 15 - 17 N•m (150 to 170 kgf•cm).

Cooling system maintenance

1. Air intake. 

2. Cylinder fins.

Œ

Remove dust and dirt from between fins.

Œ

Before each use, remove accumulated debris from bottom engine intake grille located 
between the fuel tank and starter.

NOTE

If filter is excessive dirty or no longer fits properly, replace it.

IMPORTANT

To maintain proper engine operating temperature, 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:

Œ

Air intakes are blocked, preventing cooling air from reaching the cylinder,

or

Œ

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 fins is considered "Normal
Maintenance".
Any resultant failure attributed to lack of maintenance is not warranted.
