Every 50 hours Inspect the enre machine and tubes for damage, including loose or missing components, and repair as necessary.
Check spark plug condion and gap.
Check fuel lter.
Periodically Clean the arrestor screen.
Checking the air lter (g. 19 -20)
This should be done more frequently in dusty condions.
1. Accumulated dust in the air lter will reduce engine eciency, increase fuel consumpon and allow abrasive parcles to pass into the engine. Remove the
air lter as oen as necessary to maintain in
a clean condion.
2. Light surface dust can readily be removed by tapping the lter.
3. Heavy deposits should be washed out with a suitable solvent.
4. Remove the lter cover by pressing the part of the inside cover shown as Fig.20.
Checking the spark plug
1. Use the spark plug wrench to remove the spark plug (turn counter-clockwise to remove) (Fig.15).
2. Clean and adjust the spark plug gap to
0.6˜0.7mm. Replace any damaged or visibly warn spark plug.
3. Install the spark plug nger-ght in the cylinder head,and then ghten it rmly with the spark plug wrench.
Warning: Never allow dirt or debris to enter the cylinder bore. Before removing the spark plug thoroughly clean the spark plug and cylinder head area. Allow
the engine to cool before servicing the spark plug. Incorrect spark plug installaon can result in serious engine damage.
