Observe the oil level in sight gauge (3). If the oil level is less than 1/2, add oil to the lubricator bowl.
Personal injury can result from removing hoses or fittings in a pressure system.Failure to relieve pressure can cause personal injury.Do not disconnect or remove hoses or fittings until all pressure in the system has been relieved.
Ensure that the air supply to the lubricator is OFF. Slowly loosen filler plug (4) in order to release pressure from the lubricator bowl.
Remove filler plug (4). Pour oil into the lubricator bowl. Use nondetergent SAE 10W oil for temperatures that are greater than 0 °C (32 °F). Use air tool oil for temperatures that are below 0 °C (32 °F).
Install filler plug (4). Adjust the Lubricator
Note: Adjust the lubricator with a constant rate of air flow. After the adjustment, the lubricator will release oil in proportion to variations of the air flow.
Ensure that the fuel supply to the engine is OFF.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Operate the air starting motor. Observe the drops of oil that are released in dome (1). Note: Some lubricators have an adjustment screw rather than a knob.
If necessary, adjust the lubricator in order to release from one to three drops of oil per second. To increase the rate, turn knob (2) counterclockwise. To decrease the rate, turn the knob clockwise.
