you notice a power loss with your
petrol
powered tool, a
qualified service technician will need to remove these
deposits to restore performance.

product. Spark arrestors may be in different locations
depending on the model purchased. Please contact your
nearest service dealer for the location of the spark arrestor
for your model.
