How to Effectively Test and Inspect a Chainsaw Coil- A Comprehensive Guide

How to Check a Chainsaw Coil

Chainsaws are essential tools for cutting wood and other materials, but like any other machine, they require regular maintenance to ensure they operate efficiently and safely. One of the critical components of a chainsaw is the coil, which is responsible for generating the spark that ignites the fuel-air mixture in the combustion chamber. In this article, we will discuss how to check a chainsaw coil to ensure it is functioning correctly and prevent potential problems.

Understanding the Chainsaw Coil

Before diving into the process of checking the chainsaw coil, it is important to understand its role. The coil is an electrical component that transforms low-voltage power from the battery into high-voltage electricity required to create a spark. This high-voltage spark is necessary for the combustion process in the chainsaw’s engine. If the coil is not working properly, the chainsaw may not start or run smoothly.

Tools and Materials Needed

To check your chainsaw coil, you will need the following tools and materials:

– A multimeter
– A flat-head screwdriver
– A pair of gloves
– Safety glasses

Step-by-Step Guide to Checking a Chainsaw Coil

1.

Turn off the chainsaw and disconnect the battery.

This is an essential safety step to prevent any electrical shocks or damage to the chainsaw.

2.

Locate the coil on the chainsaw engine.

The coil is typically mounted on the side of the engine and may be covered by a plastic cover. Use the flat-head screwdriver to remove the cover and expose the coil.

3.

Check the coil for any visible damage.

Look for signs of corrosion, cracks, or other physical damage that could affect its performance. If you notice any damage, replace the coil immediately.

4.

Use the multimeter to test the coil’s resistance.

Set the multimeter to the ohms (Ω) setting and touch the probes to the coil’s terminals. A healthy coil should show a resistance value within a specific range, which can be found in the chainsaw’s manual. If the resistance is outside the specified range, the coil may be faulty and need to be replaced.

5.

Check the spark plug wire connection.

Make sure the wire is securely connected to the coil and the spark plug. A loose or damaged wire can prevent the coil from functioning correctly.

6.

Reassemble the chainsaw.

Once you have completed the coil check, reattach the plastic cover and reconnect the battery.

Conclusion

Checking your chainsaw coil regularly is an essential part of maintaining your chainsaw’s performance and safety. By following the steps outlined in this article, you can ensure that your coil is in good working condition and prevent potential issues. Remember to always prioritize safety when working with electrical components and consult your chainsaw’s manual for specific instructions and requirements.
