SERVICE KITS

61355 for general repair of all 6" air motors.

GENERAL DESCRIPTION

The 6" air motor is a general purpose power unit and is used with many 2 ball, 4 ball and chop check pumps. It utilizes tie rod type construction for easy breakdown and it connects to the various lower ends via tie rods for easy operation. Consult pump model operator's manual for specific instructions. It is recommended that a muffler be connected to the ex haust port to reduce noise to acceptable OSHA standards.

Filtered and oiled air will allow the air motor to operate more efficiently and yield a longer life to operating parts and mechanisms. A filter capa ble of filtering particles larger than 50 microns should be used with an oiler. Keep the oiler supplied with a good grade of S.A.E. no. 90W non detergent gear oil, set at a rate not to exceed 1 or 2 drops per minute.

NOTICE

DO NOT OPERATE AIR MOTOR ABOVE RECOMMENDED

AIR PRESSURE OF 150 P.S.I. (10.3 BAR) OR 75 CYCLES PER

MINUTE. Air motor may be rated differently in the next assembly.

Check model plate.
