Standard Sprayers
Valve (A) is used to control spray to the spray wand or
boom:
• In the open position (valve in line with hose) spray will
ow to the boom.
• In the closed position (handle perpendicular to hose),
spray will ow to spray wand only.
Standard Sprayer Recirculation
The sprayer is equipped with a recirculation valve (B) to
aid in material agitation and pressure control.
The location of this valve will vary with the sprayer
model. This valve is in the “open” position when the valve
handle is in line with the hose (pictured), “closed” when
perpendicular to the hose.
Adjusting the recirculation valve between the open/closed
positions will a󰀨ect the pressure coming through the
spray wand only.
• Closed position is full pressure through spray wand or
boom.
• It may be helpful to adjust the pressure when spraying
with the spray wand to avoid damage to plants from
excess pressure.
• If your sprayer is equipped with a boom, this valve
should be in the “closed” position when operating the
boom.
Push switch (A) to on or o󰀨 position to start or stop
sprayer
Starting and Stopping Sprayer
IMPORTANT: Avoid damage! Operate sprayer with
transport vehicle running to avoid discharging the
battery.
NOTE: The sprayer pump to battery hookup is
a direct electrical connection. Shutting o󰀨 the
transport vehicle does not prevent operation of
the sprayer pump. To avoid accidental spraying,
disconnect the pump connection before leaving the
sprayer.

Spraying Recommendations
• Do not let sprayer run in one spot.
• Do not over spray when you use weed killers.
• Liquid spray material is recommended. Sprayer does
not agitate wettable powders.
• Timely applications of a smaller dosage are better than
large applications.
• Turn sprayer o󰀨 during turns to avoid double spraying.
• Fill sprayer where spills cannot harm grass.
Checking Machine Ground Speed
1. Drive vehicle and sprayer (half-full is optimal) across
a measured distance at a constant speed. There can
be no change in speed while measuring time. Speed
should be a comfortable speed for spraying.
2. Have someone measure the amount of time (in
seconds) it takes to travel the measured distance.
3. Speed can be found by entering data into the equation:
speed (mph) = distance (ft) x 60/time (sec) x 88, or
by consulting the following table. It is helpful to note
throttle location, gear and/or RPMs in order to maintain
accuracy.
• Follow manufacturer’s recommendations for
application of specic chemicals.
• Stop sprayer when tank is empty.
• Always purge air from spray wand at start of spraying
session.
