TROUBLESHOOTING

Poor performance of the engine and/or cutting mechanism can normally be prevented by carefully following these instructions.

Poor performance can easily be corrected even by a beginner.

When the engine does not function properly check the following three (3) points first.

•Is the 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 do it for you. For detailed TROUBLESHOOTING refer to tables 1 and 2. Locate the problem on the following charts and repair as necessary.
