SECTION 4 - MAINTENANCE
4.2 DAILY MAINTENANCE
Your Summers field sprayer will give you better service and last longer if it is properly maintained.
1. Grease all points shown.
2. Check all hydraulic components for leaks.
3. Check all sprayer system components for leaks.
4. Clean sprayer system strainer.
5. Check tank hold down straps.
6. Check nozzle patterns. If a nozzle pattern is distorted:
a. Remove nozzle tip.
b. Clean with tooth brush, wooden or plastic probe. Never use a metal object since damage
will occur.
c. Blow out nozzle tip with compressed air no greater than 40 psi. Never use your mouth to
blow out a nozzle tip.
d. Replace nozzle tip if necessary.
e. Install nozzle tip back onto sprayer.
7. During periods of use in freezing temperatures:
a. (Flush entire sprayer system with 100% RV antifreeze.) RV antifreeze is nontoxic and safe
for the environment. It must be used in 100 percent concentrations, but it is more economi-
cal then permanent antifreeze to purchase and will not corrode plastic spray components.
Read and follow antifreeze container instructions.
b. Spray solution through nozzles.
c. Allow dripless nozzles to drain by loosening each diaphragm check valve nut. With both
booms in transport position liquid accumulates near the boom pivot point. To permit drain-
age, remove the boom end cap or end nozzle and supply hose from each boom.
8. When changing chemicals, follow chemical manufacturers’ WARNINGS, instructions and proce-
dures concerning sprayer system cleaning.
