If you require a replacement, do not operate this machine until all parts are present and in proper working order. Do not modify or create accessories for this equipment. Using modified components may result in damage to this equipment and may void the warranty.
3.2 - Compressor Oil Check 1. Ensure the air compressor is on a level surface. 2. Inspect compressor oil by checking oil level indicator 3. The window should be filled past the midway point indicated by a red dot. If the oil level is below the red dot, add more oil to the pump. 3.3 - Fuel Level Check 1.
Gasoline is highly flammable and explosive under certain conditions. Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow open flames or sparks in the area where the Air Compressor is being refueled or where gasoline is stored. Do not overfill the tank. Be careful not to spill fuel when refueling.
Check the air filter using the maintenance schedule. Always inspect air filter before using the Air Compressor. Clean Air Filter every 3 months or after 50hrs of operation according Section 5.4: Air Filter Service procedure. 3.5 - Initial Inspection All air compressors have been inspected carefully before leaving the factory. It is possible that poor handling during transport caused some damage to the compressor.
