Basic Engine Maintenance (gas engine)
• For detailed engine maintenance and technical
specifications refer to the separate gasoline engine
manual.
• All service to the engine should be performed by a dealer
authorized by the engine manufacturer. To locate a dealer
in your area, look in the Yellow Pages of your telephone
directory under Gasoline Engines, Garden & Lawn
Equipment & Supplies, Lawn Mowers, etc.
• The gas engine is warranted exclusively by the engine
manufacturer.
• Use a premium quality motor oil certified to meet or
exceed U.S. Automotive requirement SG.or SF. SAE
10W30 is recommended for general all temperature use.
Other viscosities may be required in other climates.
• Use only a (NGK) BP6ES or BPR6E spark plug. Gap the
plug to 0.028 to 0.031 In. (0.7 to 0.8 mm) Always use a
spark plug wrench.

Engine Operation and Service
1. Clean and oil air filter pad on gasoline engine every 25
hours or once weekly. Do not permit the air intake screen
around the fly wheel of the gas engine to load up with
paint or trash. Clean it regularly. The service life and
efficiency of the gas engine model depends upon keeping
the gasoline engine running properly. Change the oil
in the engine every 100 hours. Failure to observe this
may result in engine overheating. Consult the engine
manufacturer's service manual provided.
2. To conserve fuel, service life, and efficiency of the sprayer,
always operate the gasoline engine at the lowest RPM
at which it runs smoothly without laboring and delivers
the amount required for the particular painting operation.
Higher RPM does not produce higher working pressure.
The gasoline engine is connected to the hydraulic pump
by a pulley combination designed to produce full paint
delivery at maximum RPM.
3. The warranty on gasoline engines or electric motors is
limited to the original manufacturer.
