Operating Instructions

• Connect the air motor to the air line by a proper connection. The air inlet threads are 1/2" BSP. The air hose size should be minimum 12 mm ID and the length of the air hose should be 3 meters maximum. There should be no water in the air line.
• If speed is to be varied, an inline airline regulator should be provided near the air inlet port of the air motor.
• If the air motor is to be operated by solenoid or manual direction control valves, the valves should be of 1" size. The valves should not be more than 3 meters from the air motor.
• For non-reversible use, a silencer should be connected to the exhaust port of the air motor. Various types of silencers are available. Too much silencing will affect the speed and torque of the air motor. Proper selection of the silencer is important for balancing the sound level and the speed/torque.
• The optimum air pressure for operation is 4 kg/cm2. Maximum air pressure should not exceed 6 kg/cm2.
• Lubrication is important for the air motor. An inline air lubricator should be fitted. The size should be minimum ½'. If that is not possible, the lubricating oil (10 ml) should be put inside the air motor through the air inlet after every 4 hours of operation.
• If the air motor is going to remain idle for a long period of several days, it should be lubricated with oil and both the ports should be plugged.
• Do not hammer the output shaft of the air motor with hammer while putting a coupling on it. The coupling should slide easily on the shaft.

Maintenance Instructions

• Use a hand press for removing the front plate and the rear plate from the housing of the air motor. Do not hammer the rotor.
• Use hand press for assembly of ball bearings into front and rear plates.
• Fully tighten all the screws on assembly before starting the motor.
• The rotor should be adjusted inside the housing by gently hammering the centre holes on both sides by a centre punch. The rotor should be free to rotate by using a spanner in hand.
• Proper and timely lubrication is a must for trouble free performance.
• Use genuine AMRO spare parts.
