Oil level dipstick to properly maintain York and SLM belt driven compressors. When touching the floor inside the compressor, each of the 13 notches on the dipstick represents 1 ounce of fluid level. Also provided is a 2 OZ syringe to make filling the compressor easy. Access for oil level and filling can be found through the bolt hole on either side of the compressor (RH side only for SLM compressors).
