While holding the piston upright in your left hand, take the piston ring groove cleaner tool in your right hand and line up the cleaner tool guides with the second (middle) piston ring groove.
Press the handle on the piston ring groove cleaner tool and slide the cleaning bit onto the appropriate piston ring grooves.
Once the cleaning bit is in the appropriate ring grooves of the piston, make sure the tool handle clicks in to place.
NOTE: There is only one notch on the tool for the handle to engage.
Hold the piston steady and rotate the tool counter-clockwise five to six times to remove any carbon deposits in the piston ring grooves. Do not rotate the tool clockwise.
