Mounting This product can be installed in any orientation. Mount the motor to a solid metal base plate that is mounted to a stable, rigid operating surface. Use shock mounts to reduce noise and vibration. Install a pressure regulator or simple shut-off valve to control motor. Connection Do not use a hammer on the shaft or connections. Lubricating the drive shaft will make assembly easier. Use a puller for removal of pulleys, couplings and pinions on the motor shaft.
PAGE 4
Use a pressure regulator and/or simple shut-off valve to regulate the motorʼs speed and torque. This will provide the required power and will conserve air. Open the air supply valve to the motor. Set the pressure or flow rate to the required speed or torque. Adjust the lubricator to feed one drop of oil for every 50-75 CFM (1.5-2 M3 per minute) of air moving through motor. Check the oil level daily. Operate the motor for approximately 2 hours at the maximum desired load.
