Maintaining the Fluid Section

If the sprayer is going to be out of service for an extended period
of time, it is recommended that following cleanup, a kerosene
and oil mixture be introduced as a preservative. Packings
may tend to dry out from lack of use. This is particularly true
of the upper packing set for which EasyGlide (P/N 0508619) is
recommended in normal usage.
If the sprayer has been out of service for an extended period
of time, it may be necessary to prime the pump with solvent.
It is extremely important that the threads on the siphon hose
coupling are properly sealed. Any air leakage will produce erratic
operation of the sprayer and may damage the system. The up
and the down strokes should be approximately equal in time (one
should not be faster than the other). A fast up or down stroke
may indicate air in the system or malfunctioning valve or seats
(see the Troubleshooting section).

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) 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.
Daily
1. Check engine oil level, and fill as necessary.
2. Check gasoline level, and fill as necessary.
Always follow the fueling procedure outlined
earlier in this manual.
Danger
First 20 Hours
1. Change engine oil.
Every 100 Hours
1. Change engine oil.
2. Clean the sediment cup.
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

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 is limited to the original
manufacturer.
Adjusting the Tracking of the Front Caster
The front caster is set by the factory to track in a straight line.
Use the following procedure if adjustment the caster becomes
necessary.
1. Loosen the two hex screws in
the top of the caster mounting
bracket.
2. Turn the caster mounting
bracket slightly in the desired
direction.
The front caster locking
i
pin must be engaged
during tracking
adjustment.
3. Tighten the two hex screws.
4. Check the tracking of the front
caster. If the caster does not
track straight, repeat the above procedure.
