TROUBLE SHOOTING
The details of TROUBLE SHOOTING refer to Table 1 end 2.
• Refer to the chart to locate the problem artd repair as necessary.
FAILURES such as difficulty in starting engine, irreoularity in functions and abnormality in cutting performances can
normally be prevented completely if a little attention is paid in advarKe.
Such failures can be readily disposed of even by a be 9 inr>er.
In the following we wish to give essential points in countering failures of the chain saw and the trouble-shooting table.
When the engine does not hjr>ction properly, check the following 3 points systematically in particular:
• Whether compression of the engirt is adequate or not.
o Whether the fuel system is in good condition and fuel is supplied fluently, or not.
• Whether the electrical system is in good condition and the spark plug sparks correctly, or not.
When there is serious trouble with your chain saw, do not try to repair at random yourself, but have your chain saw
distributor or dealer do it for you.
