6.5 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.
• Use a premium quality motor oil. 10W30 is recommended for
general all temperature use. Other viscosities may be required
in other climates.
• Use only a (NGK) BR-6HS (PL4950), or (NGK) BP6ES / BPR6E
spark plug (PL6950/PL8950). Gap the plug to 0.028 to 0.031
In. (0.7 to 0.8 mm) Always use a spark plug wrench.

3. Clean and re-gap the spark plug.
4. Clean the spark arrestor.
Weekly
1. Remove the air filter cover and clean the element. In very
dusty environments, check the filter daily. Replace the
element as needed. Replacement elements can be purchased
from your local engine manufacturer dealer.
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.
