AIR AND LUBE REQUIREMENTS (cont)
• Filtered and oiled air will allow the pump to operate more efficiently
and yield a longer life to operating parts and mechanisms.
• Lack of or an excessive amount of lubrication will affect the perfor-
mance and life of this pump. Use only recommended lubricants.
• DAILY Fill air line lubricator with a good grade of S.A.E. NO. 90W
non-detergent gear oil, adjust to 1 to 2 drops per minute.

connect air supply and relieve all pressure from the system.
