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?
