16. If you had to make any adjustments in step 15 or 16, repeat steps 10
thru 15
17. If you still cannot get the desired operating pressure, change the spray

SPRAYER SHUT DOWN AND STORAGE
1. Run the pump until all liquid is pumped out of the system.
Do not run
the
pump dry for more than 30 seconds
. Then shut the engine off and fill the
tank with clean, clear water. Pump the tank empty. If the sprayer is
going
to be stored for several days, the following procedure is recommended:
2. Put 1 gallon of anti-freeze and 1 gallon of water or equivalent in the tank
if temperatures are expected to be below 0°F. Check the freeze chart
of the anti-freeze and add anti-freeze to recommended rating for ex-
pected temperatures.
3. Start the engine and allow the pump to operate just long enough to fill
the system with the anti-freeze solution. This is accomplished when only
anti-freeze mixture is coming out of the spray gun. Close the spray gun
and allow the pump to operate for 1 minute.
4. Shut the system off and place in storage. This procedure keeps all the
valves and other moving parts protected during storage.
5. When you are ready to use the system again, start the engine and allow
the pump to operate until all anti-freeze has been pumped out of the
system. Fill the tank with clear water and one bottle of ammonia-based
cleaning liquid. Run the pump until this solution has been pumped out.
Refill the system with clear water and pump the system dry once more.
The spray system is now ready to go to work.
NOTE: The above procedure is highly recommended for sprayers in cold cli-
mates as a prevention of freezing and breaking the pump.
STANDARD MAINTENANCE CHECKS
FILLING AND CHANGING LUBRICATION OIL
Take off the oil cap (ref # 4) and fill with 30-weight oil to the full line on the
indicator window or dip-stick. It is recommended to change oil every one
hundred (100) hours of operation.
