SPRAY CART MAINTENANCE
Pump
After each use, thoroughly flush the pump with a neutralizing
solution for the liquid that was just pumped. Follow with a
clean water rinse.
LONG-TERM STORAGE
When storing the spray cart for more than 30 days, perform
the following procedure:
Drain the pump thoroughly, and open any drain plugs.
Remove all hoses from the pump and blow the pump
dry with air.
Inject an antifreeze/rust inhibitor into the pump and plug
all pump ports.
Drain the fuel tank completely, or add STA-BIL® to the
fuel.
Run the engine until all gasoline in the carburetor is
completely consumed.
Completely drain the oil from the crankcase and refill
with fresh oil.
Remove the spark plug, pour 2–3 cm³ of SAE 30 oil into
the cylinder, and crank slowly to distribute the oil.
Slowly pull the recoil starter grip and stop at the
compression point.
Wipe the spray cart clean with a cloth.
Cover the spray cart with a plastic sheet and store it out of
direct sunlight, in a moisture-free and dust-free location.
