How to clean a spark plug on a hedge trimmer

This is an article about hedge trimmer spark plug maintenance.

To keep your Husqvarna hedge trimmer in optimal condition it is important to clean or replace the spark plug.

For this you will need:

• Protective gloves
• Wire brush
• Combi spanner with a large opening or any kind of appropriate tool: The tool depends on the size of the spark plug
• Spark plug: Please check the operator’s manual for your product for the correct spark plug size

Examine the spark plug if:

• The engine is low on power
• The engine is not easy to start
• The engine does not operate correctly at idle speed

Spark plug maintenance:

1. To access the spark plug, take off the cover.
2. Once the cover has been removed, pull the cap and wire off the spark plug. Before you go further, make sure that there is no corrosion on the top of the contact, and if there is, clean it with a wire brush. Also make sure that you clean the area so it is free from dirt and debris.
3. To remove the spark plug, use a combi spanner with a large opening and turn it anticlockwise. Check the spark plug for any cracks or carbon deposits, check the contacts on the electrode.
4. If there are any carbon deposits on the electrode, clean it with the wire brush.
5. If there is no damage to the spark plug and you were able to clean the electrode and the contact post, thread it back into the engine. Make sure that it is firmly seated with the socket wrench. Do not overtighten.
6. When applying the cap and wire to the post, make sure that it clicks into position.

CAUTION: Make sure that you use the correct spark plug gap for your specific hedge trimmer. You can find this information in the operator’s manual or if you visit your local authorised dealer. An incorrect spark plug can cause damage to the product.
