Common questions about manuals, registration, and support for this brand.
For most General Pump models, it is recommended to perform the first oil change after 50 hours of use to remove impurities. Subsequent oil changes should be done every three months or 300 hours of operation, whichever comes first.
Maximum temperatures vary depending on the model, but standard high-temp units handle up to 165°F (73°C). Please review the specific pressure rating in your manual to prevent cavitation and internal damage.
Milky oil indicates condensation or water is entering the crankcase and mixing with the oil. You should change the oil more frequently if this occurs, and check your packings and seals if the milky appearance persists.
