Spraying Tips

• Check sprayer tip height. Adjust sprayer tip height, if needed, before operating. 15 and 25 Gallon Sprayer, 43 cm (17 in.)
• Do not let the sprayer run in one spot.
• Do not over-spray when you use weed killers.
• Liquid spray material is recommended. The sprayer does not agitate wettable powders.
• Timely applications of a smaller dosage are better than large applications.
• Turn the sprayer off during turns to avoid double spraying.
• Fill the sprayer where spills cannot harm grass.
• Follow the manufacturer’s recommendations for the application of specific chemicals.
• Stop the sprayer when the tank is empty.

Adjusting Tip Height

1. Attach sprayer to the machine.

2. Measure from spray tip to the ground. Distance to the ground (A) should be approximate: 43 cm (17 in.)
   If necessary, adjust the boom height by raising or lowering the boom on the threaded boom supports (B).

3. Check spray tips (C). Tips should be aligned with the boom (D) as shown. If necessary, loosen the spray tip cap nut (E). Align spray tip (C) and tighten cap nut.

4. Test spray pattern with water on driveway or sidewalk. Each spray tip pattern should spread out to the right and left sides, rather than to the front and back of the boom. There should be some spray overlap between each tip and the spray patterns should be consistent.

Starting and Stopping Sprayer
IMPORTANT: Avoid damage! Operate the sprayer with the transport vehicle running to avoid discharging the battery.
NOTE: The sprayer pump to battery hookup is a direct electrical connection. Shutting off the transport vehicle does not prevent the operation of the sprayer pump. To avoid accidental spraying, disconnect the pump connection before leaving the sprayer.

Push switch (A) to on or off position to start or stop sprayer

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 flow to the boom.
• In the closed position (handle perpendicular to a hose), the spray will flow to the 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), and “closed” when perpendicular to the hose. Adjusting the recirculation valve between the pen/closed positions will affect the pressure coming through the spray wand only.

• The closed position is full pressure through a 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.

Using Hand Wand

1. Turn the valve to select handgun operation.

2. Turn the selector lever to the handgun position.
   NOTE: Removal of spray tip (A) allows for quick cleaning/rinsing of the sprayer tank.

3. Adjust nozzle:
   • Nozzle Angle – Loosen locknut (B). Turn the nozzle tube (C) to the desired position and tighten the locknut.
   • Nozzle Spray Pattern – To change the spray pattern, tighten or loosen the nozzle as desired.

4. Squeeze the handle (E) to spray.

5. Push-lock (F) forward to the lock handle in the ON position.

Spraying Recommendations

• Do not let the sprayer run in one spot.
• Do not over-spray when you use weed killers.
• Liquid spray material is recommended. The sprayer does not agitate wettable powders.
• Timely applications of a smaller dosage are better than large applications.
• Turn the sprayer off during turns to avoid double spraying.
• Fill the sprayer where spills cannot harm grass.
• Follow the manufacturer’s recommendations for the application of specific chemicals.
• Stop the sprayer when the tank is empty.
• Always purge air from the spray wand at the start of the spraying session.

Checking Machine Ground Speed

1. Drive the 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.

Speed In
mph| Time (sec) required to travel a distance of
---|---
