■ GEARCASE

• Supply multi-purpose grease at every 25 hours of

use.

• Remove the bolt of the grease nipple and the bolt

opposite side of the grease nipple. Install new

grease into the grease nipple to arrange for old

grease to exit from the opposite side.

■ MAINTENANCE BEFORE STORAGE

• Old fuel left in the carburetor may cause starting

failure. When a series of operation finished, make

sure to empty the fuel tank and drain the carburetor.

• Check all parts and the functions. If the failured or

damaged parts have been found, replace them with

new ones.

9. Maintenance

Before cleaning, inspecting, or repairing the unit,

make sure that the engine has stopped and is cool.

■ BLADE

Check the blade and the fasteners for looseness,

cracking, or bending.

■ AIR FILTER

A clogged air filter will reduce the engine performance.

Check periodically and clean the filter element in warm,

soapy water as required. Dry completely before

installing. If the element is broken or shrunk, replace

with a new one.

■ FUEL FILTER

When the engine runs short of fuel supply, check the

fuel strainer for blockage.

■ SPARK PLUG

Starting failure and mis-firing are often caused by a

fouled spark plug. Periodically clean the spark plug,

and replace with a new one as required.
