Maintaining the Engine
When transporting a sprayer with a gas engine, make
sure the fuel is shut off.
NOTE: For detailed engine specications and maintenance,
refer to the separate engine manual supplied with
this sprayer.
Important Facts Concerning this Sprayer
This gas-powered sprayer contains a clutch that engages when
the sprayer is pumping. The sprayer’s pressure control system
engages and disengages the clutch to control pressure. To prevent
unnecessary wear to the clutch, it is advisable to adjust the engine
speed and pressure setting to limit the amount of times the clutch
engages and disengages. To reduce clutch wear, refer to the
following examples.
Example:
Operating one gun with a .019 tip — reduce the engine speed by
adjusting the throttle to a low or medium setting and increase
pressure only until the heavy ends of the spray pattern have been
eliminated.
Example:
Operating one gun with .023 tip — increase engine speed to a higher
setting and increase pressure until the heavy ends of the spray
pattern have been eliminated.
Example:
Spraying light-bodied materials at low pressure — to reduce surging
at the gun and to decrease clutch wear, reduce the engine speed to
idle and reduce pressure until the desired spray pattern is achieved.
Routine Engine Maintenance
Daily
• Check and ll the gas tank.
• After the rst 20 hours of operation, drain the oil and rell
with clean oil. Check the engine oil level and ll as necessary.
Weekly
