Pul-Blast
AR pump system
Read this manual completely before operating: follow all safety instructions.
Operating instructions
1. Set fan speed with the lever on the gearbox, illustra-
tion on previous page, BEFORE engaging the PTO drive.
Engage the PTO at low RPM then gradually increase to
operating speed.
DO NOT engage PTO with tractor and implement at
an angle (as if going around a corner). For drive-
train longevity the PTO drive shaft and Pul-Blast Power
Tongue assembly should be in-line whenever engaging
or dis-engaging the PTO. Models with CVHitch option
should also only engage the PTO with the tractor and
implement in-line.
2. Fully open relief valve during start-up for proper pump
priming and to prevent water hammer damage.
3. To accurately set a prescribed working pressure, the
spray systems have to be operating: airboom manifolds,
spray boom or handgun line, as required. When these
spray systems are turned off the pressure gauge will
show an increase in system pressure.
4. Maximum ground speed
will vary depending on foliage
density, ground condition, target distance, applica-
tion rate, and tractor horsepower. Use the Calibration
Instructions for Rears Airblast Sprayers to select an
operating gear and speed for your application.
5. Never close the suction valve when the system is
running- pump damage will occur.
First disengage the
pump system, before closing the suction valve (when
checking the suction strainer, for example).
6. A clogged suction strainer can cause pump
damage.
Check and clean the suction strainer often:
ideally when refilling the tank (especially if using ditch
or cloudy well water).
7. DO NOT OVERSPEED THE PUMP
Damage will result.
The pump is designed to operate at 540RPM or below.
8.
Do not shut off the PTO when turning a corner. Wait
until the tractor and implement are in-line, then reduce
the PTO speed and dis-engage the PTO drive.
9. Always wear proper protective equipment-
read the
labels of all materials being used and observe all han-
dling instructions.
10.
Be alert for clogging and changes in nozzle patterns. If
nozzles clog or other troubles occur in the field, shut
the sprayer off and move to an unsprayed area before
dismounting from the tractor.
11.
Never try to unclog a nozzle by blowing through it.
Always carry extra spray tips.
Beginning of season
1. Follow the lubrication schedule.
2. Check air pressure in tires.
3. Drain and refill gearbox to correct level.
4. Tighten all fasteners.
5. Replace worn spray tips.
6. Check pump belt tension.
7. Inspect belts and fan blades- keep clean.
8. Review this operator’s manual.
End of season and storage
1.
Shelter sprayer in a dry place.
2.
Clean thoroughly, inside and out. Flush tank and pump
system with water.
3.
Flush pump & system with RV antifreeze solution.
When draining spray manifolds, remove the check valve
cap from the top-most nozzle assembly to release
vacuum.
Leave antifreeze solution in the pump for storage.
4. Lubricate as instructed in the schedule.
5. Remove fan and inspect thoroughly for damage or
cracks. Replace if needed.
6. Re-paint all parts where paint has been worn.
7. Block up frame to lighten load on tires. Do not deflate
tires. Cover tires if exposed to sunlight, grease, or oil.
8. Make a list of replacement parts needed and order early.
For the best performance next season, have your dealer
service the machine prior to storage.
Operation, cont’d
12.Flush tank and pump system
with clean water at the
end of each day to keep plumbing clear. Fully open
relief valve to discharge back to tank at
ZERO pres-
sure
on gauge.
13.Do not clean, lubricate, or adjust the implement
while the PTO is rotating or the tractor is running.
14.If excessive vibration develops, shut down im-
mediately.
Possible causes: pump diaphragm, drive
train bearings, drivelines, u-joint crosses, or fan have
become damaged or worn.
