MAINTENANCE
CLEANING
• After spraying, clean the tank thoroughly. If some
spray liquid is left inside, drain tank completely.
• Pumping causes air to be taken in and the
remaining liquid to be discharged. Pump until liquid
and air are coming out through the nozzle.
• Refill tank with a few quarts of clean, soapy water
and pump the water out as explained above
(if necessary, repeat this procedure several times).
• If the shut-off valve is removed, the pump can be
flushed quickly. Improper spray distribution is the
result of a clogged nozzle, which is easily removed
and cleaned.
• Do not use aggressive cleaning agents or abrasives.
• Follow manufacturer recommendations for disposal
of waste water and chemicals.
• Activated charcoal in liquid or other form may be
used to absorb chemicals in tanks or spills.
MAINTENANCE AND STORAGE TIPS
• After operation, store sprayer away from direct
sunlight to prevent UV damage.
• After removing pump or when mounting a new
Viton
®
collar, treat both collar and piston with
water-resistant grease.
• Before winter, drain all liquid from tank, lines and
pressure cylinder. (See Figure 6)
NOTE: Leave shut-off valve locked in the open
position to prevent freezing.
• Regularly inspect hose, wand, pump, tank and shut-off
valve for wear, damage or leaks. Repair promptly.
• Occasionally lubricate cap gasket.
NOTE: The cap gasket (#4061345) is
pre-lubricated for improved sealing.
Occasional lubrication with Solo Superior
Grease (#9850-P) or petroleum jelly is
recommended.
