How to use 1R181 Ignition checker
Do not remove Spark plug. (It is necessary to check that sparks are certainly generated by pulling Starter
rope even against the compressed air in Cylinder for normal use.)
The conventional method to check directly for spark, with Spark plug attached on the outside of Cylinder, is
uncertain and therefore prohibited.
Persons with a pacemaker should not use this checker.
Do not touch any terminal during use because dangerous high voltage is applied to each terminal.
Make sure that the terminals of 1R181 are
firmly tightened.
Do not overtighten Spark gap adjusting knob.
