Maintenance and Lubrication
Proper servicing and adjustment is the key to the long
life of any farm implement. With careful and system-
atic inspection, you can avoid costly maintenance,
time and repair.
Sprayer/Boom Maintenance
Proper servicing and maintenance is the key to the
long life of all farm equipment. With careful and sys-
tematic inspection of your sprayer, you can avoid
costly maintenance, downtime and repair.
1. After several hours of operation, check sprayer
for loose bolts, pins and hose clamps.
2. Check hoses, pumps, valves and fittings for
leaks. Always wear rubber gloves when making
repairs and adjustments.
3. Clean nozzles with an air hose with less than 30
P.S.I. Periodically replace nozzles.
4. Keep elevator slide pads properly adjusted. Lu-
bricating slide pads with grease may cause dirt
accumulation that jams elevator. If necessary,
use silicone spray on slide pads.
5. For lubrication points and intervals refer to “Lu-
brication” on Page 46.
6. Check for proper air pressure in the sprayer tires.
22 P.S.I. is recommended for the 13.6 x 38 tires.
7. Wash sprayer and boom daily using a safe sol-
vent, or soap and water.
8. If equipped with a foam marker, clean the air filter
on the air pump no less than once a week, even
more often in extreme conditions.
9. Once a season lubricate multiple nozzle bodies
with silicone spray. Remove nozzle and spray
into opening to lubricate nozzle body so it will
turn. DO NOT use petroleum based lubricant as
this will cause the seals to swell and make it im-
possible to rotate the nozzle body.
Equipment Cleanup
Nozzles should be cleaned with a low pressure {less
than 30 psi} air hose, and periodically replaced. Haul
a supply tank of water so you can clean the spray
tank and applicator out in the field. Never wash tank
out in the yard or at a car wash.
Dispose of leftover chemical in the same manner de-
scribed on the manufacturer’s label of the chemical
last used in the sprayer. Rinse out the tank and spray
the rinse water on the last field that was sprayed.
Flush the sprayer with fresh water and spray the wa-
ter in the field that was last sprayed. While the sprayer
is being flushed at the field, turn the boom section
switches "on" to flush the nozzles, then turn them "off"
to flush out the throttling valves and bypass lines {if
equipped}. Repeat this procedure several times.
General Information
If equipment is to be used in freezing or near freezing
conditions, protect pump and plumbing system by
thoroughly draining liquid and pumping antifreeze
{Great Plains strongly recommends the use of recre-
ational vehicle antifreeze} solution through the
plumbing system.
Before working on, servicing or making adjustments
on sprayer, always disengage power, shut off tractor
engine, make sure all moving parts have stopped,
and all pressure in the system is relieved.
Check the conditions of hoses and connections fre-
quently. Release the system pressure before
working on the sprayer. To release the pressure flip
the boom section switches on and off without the
pump running. Always wear rubber gloves when
making repairs or adjustments. Make sure all “Per-
sonal Safety Equipment” {gloves, goggles, etc.}
listed on Page 5, are stored in an easily accessible
place but protected from potential contamination from
dust or chemicals.
Check the sprayer for any loose bolts, pins, and hose
clamps.
Check the hoses, pumps, valves, and fittings for any
leaks.
Inspect all parts of the sprayer for wear and rust. Re-
pair and paint parts as necessary.
Pump Maintenance and Repair
Ace Pumps
The centrifugal pump is designed for long life and ser-
vice. Through the years, there may be a need to re-
place the mechanical seal or service some
component of the pump. A mechanical seal may
weep slightly, but if it starts to drip, the pump will have
to be disassembled. Before disassembling the pump,
be sure to wash it out with fresh water.
If the pump is leaking, before removing it from the
sprayer, run the pump with adequate water in the tank
to diagnose the actual pump problem.
