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.

EIGHT CUTTER BLADE

• Use only the blade designated by the

manufacturer for this model.

• When crack is noticed on the blade, never use

it, but replace with a new one.

• 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.

- In sharpening the edge by use of a grinder, do

not cool the cutter abruptly by immersing it in

water.
