MAINTENANCE
It is not recommended that you use an Airline Oiler with your Spark Plug Cleaner. The Airline Oiler
will clump your abrasive material and eventually clog your Spark Plug Cleaner.
Every year (more often with constant use), check the condition of the abrasive material. If necessary,
replace the abrasive material with approved abrasive material from Harbor Freight Tools.
