• Primary Winding Test
The primary winding of the coil can be tested by positioning the multimeter’s leads on the distributor’s external electric contacts.
• Secondary Winding Test
You can test the secondary winding of the coil by touching one multimeter lead on an outer electrical contact and the other lead on the main distributor wire’s inner electrical contact point.
• Monitoring the Measurements
Always compare the final measurements to the level specified for the chainsaw model. If these numbers are outside the range, it’s time to replace the coil.
• Regular Chainsaw Maintenance
Regular chainsaw maintenance includes checking the oil, sharpness, and damage of the chain and bar, cleaning the air intake ports and air filter, filing off burrs, and checking and cleaning the spark arrestor screen and carburetor.
• Dealing with a Flooded Chainsaw
If your chainsaw is flooded, follow these steps from the University of Missouri Extension to clear the flooded engine and restart your chainsaw.
By following these pointers, you can efficiently test and maintain your chainsaw while ensuring maximum longevity. As always, refer back to the user manual for model-specific information and guidelines.
