STORAGE
FLUSH PUMP AFTER USE
One of the most common causes for faulty pump
performance is gumming or corrosion inside the
pump. Flush the pump and entire system with a
solution that will chemically neutralize the liquid
pumped. Mix according to manufacturers
directions. This will dissolve most residue
remaining in the pump, leaving the inside of the
pump clean for the next use.
TO PREVENT CORROSION
After cleaning the pump as directed above, flush
it with a permanent type automobile antifreeze
(Prestone, Zerex, etc.) containing a rust inhibitor.
Use a 50% solution - that is, half antifreeze and
half water, or fill pump with FLUID FILM and then
drain it. A protective coating of FLUID FILM will
remain on the inner pump surfaces. Save the
excess FLUID FILM for the next application. Plug
the ports to keep out air during storage. For short
periods of idleness, non-corrosive liquids may be
left in the pump, BUT AIR MUST BE KEPT OUT.
Plug ports or seal port connections.
IMPORTANT: FREEZING TEMPERATURES MAY
DAMAGE THE PUMP, FLOWMETER, THE
MOTORIZED CONTROL VALVE, AND THE
ELECTRIC SOLENOIDS IF THE WATER IS NOT
DRAINED COMPLETELY!
Remove and clean the Flow Meter at the end of
each spraying season. See page 16. Clean Flow
Meter turbine and inlet hub. Clean off all metal
filings and wettable powders which have hardened
on the plastic and metal parts. Check the inlet
hub and turbine assembly for worn or damaged
turbine blades and bearings. Flush Flow Meter
with clear water and drain.
IMPORTANT! When a high pressure washer
or garden hose is used for cleaning, it is
necessary to cover or otherwise protect the
control Console. Water entering the Control
Console will cause serious damage, to the
electronic system.
Remove the Control Console from the Vehicle for
storage, or otherwise protect it from the elements.
Should the Control Console require service, refer
to the serial number decal on the bottom of the
console when requesting assistance or information
from your TORO distributor.
SERVICING AFTER STORAGE:
Flush the entire spraying system with clean water
and detergent.
Flush the entire spraying system again with clean,
clear water to rinse.
Drain entire spraying system.
STORAGE AND DISPOSAL OF
CHEMICALS:
Follow chemical manufacturers recommendations
for storage and disposal of chemicals.
