TROUBLE SHOOTING
Poor performance of the engine and/or trimming mechanism can normally be prevented by carefully
following instructions.
Poor performances can easily be corrected even by a beginner.
When the engine does not function properly check the following three (3) points first.
•
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
do it for you. For detailed TROUBLE SHOOTING refer to tables 1 and 2. Locate the problem on the
following charts and repair as necessary.

•
Round the teeth bottom for 1- 2 mm radius in
order to avoid the crack using a round file.
- Rounded part is not to be sharpened.
- Sharpen each cutter equally so as to retain
the balance of the blade.
