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 2Ćball, 4Ćball 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 exĆ 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 capaĆ 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 nonĆ 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.
Check model plate.
Air motor may be rated differently in the next assembly.
