A ground lug is located on the air motor. This ground lug al- lows proper grounding of the pump.

AIR AND LUBE REQUIREMENTS Figure 1

A filter capable of filtering particles larger than 50 microns should be used with a lubricator.

Filtered and oiled air will allow the pump to operate more ef- ficiently and yield a longer life to operating parts and mecha- nisms.

Use an air line lubricator and keep it supplied with a good grade of S.A.E. #90W non-detergent gear oil set at a rate not to exceed approximately 1 drop per minute.
