Poor performance of the engine and/or spraying mechanism can normally be prevented by carefully following
the above instructions.
Poor performances can easily be corrected even by a beginner.
When the engine does not function properly check the following three (3) points fi rst.
• Is engine compression adequate?
• Is fuel system in good condition and is enough fuel being supplied?
• Is electrical system in good condition and is spark plug operating normally?
When there is serious trouble with the unit, do not try to repair it yourself but have your distributor or dealer
