.
To determine the throttle setting for attaining the
appropriate speed, mark off 100,200 and 300 feet
intervals. The speed chart at the bottom of page
11 indicates the number of seconds it takes to
travel these distances. Set the throttle and, with a
running start, travel the distances in the number of
seconds indicated by the speed chart. Once you
have determined the throttle and gear settings
needed, mark the throttle location so that you can
easily resume the same speed after stopping.
7. Add the chemical solution to the tank and drive to
the starting place for spraying.
.
Set the throttle at the position determined in step
6 to attain the proper ground speed. Reach back
and flip the pump/motor switch to the "ON" posi-
tion to start the solution spraying from the nozzles.
9. When not being used, the outer boom arm assem-
blies may be folded in and attached to the boom
transport bracket at the center of the boom.
10. Stay clear of flowers, shrubs and evergreen trees
when spraying weed control solutions to prevent
contact of the solution with these sensitive plants.
MAINTENANCE
1 .
2.
Do not store sprayer with any solution left in tank.
Periodically clean the strainer in the end of the
intake hose at the bottom of the tank. Remove the
nylon swivel nut from the hose, pull out the screen
and flush it with clear water.
AFTER EACH USE
.
4.
After use, fill the sprayer part way with water, start
the sprayer and allow clear water to be pumped
through the plumbing system and out through the
boom assembly and the handgun. Use the hand-
gun to thoroughly wash all internal parts of the
tank, the outside of the tank and the boom.
Refill the tank about half full with plain water and
a chemical neutralizer and repeat the cleaning
instructions above. Flush the entire sprayer with
the neutralizing agent. Follow the chemical manu-
facturers instructions for disposal of all wash or
rinsing water.
ATTENTION!
Do not allow chemicals to sit in pump for
extended times of idleness. Some chemicals
will damage the pump valve if allowed to soak
untreated for a length of time. Always flush
the pump with water after each use. Follow
the procedures in the AFTER EACH USE
instructions for flushing and disposal.
WINTER STORAGE
.
Drain all water out of the sprayer, paying special
attention to the pump and handgun. These items
are especially prone to damage from chemicals
and freezing weather.
.
The sprayer should be winterized before storage
by pumping a 50-50 solution of water and R. V.
antifreeze through the entire plumbing. Proper
care and maintenance will prolong the life of the
sprayer.
