Multi Pro® WM Turf Sprayer

• Make sure that operators are thoroughly trained and familiar with the Operator’s Manual, the Operator’s Manual of the Workman vehicle, Training Material, Engine Manual, and all labels on the Workman vehicle.

• Be sure to establish your own special procedures and work rules for unusual operating conditions (e.g. slopes too steep for vehicle operation). Use the third high lockout switch if high speed could result in a safety or vehicle abuse situation.

• Slow down before you approach an obstacle. This gives you extra time to stop or turn away. Hitting an obstacle can damage the vehicle and its contents. More important, it can injure you and your passenger.

• Gross Vehicle Weight (GVW) has a major impact on your ability to stop and/or turn. Heavy loads and attachments make a vehicle harder to stop or turn. The heavier the load, the longer it takes to stop.

• Turf and pavement are slick when they are wet. It can take 2 to 4 times as long to stop on wet surfaces as on dry surfaces. If you drive through standing water deep enough to get the brakes wet, they will not work well until they are dry. After driving through water, you should test the brakes to make sure they work properly. If they do not, drive slowly while putting light pressure on the brake pedal. This will dry the brakes out.

Operating the sprayer on a hill may cause tipping or rolling of the sprayer, or the engine may stall and you could lose headway on the hill. This could result in personal injury.

• Do not accelerate quickly or slam on the brakes when backing down a hill, especially with a load.

• Never drive across a steep hill; always drive straight up or down or go around the hill.

• If the engine stalls or you begin to lose headway while climbing a hill, gradually apply the brakes and slowly back straight down the hill.

• Turning while traveling up or down hills can be dangerous. If you have to turn while on a hill, do it slowly and cautiously. Never make sharp or fast turns.

• Heavy loads affect stability. Reduce the weight of the load and your speed when operating on hills.

• Avoid stopping on hills, especially with a load. Stopping while going down a hill will take longer than stopping on level ground. If the sprayer must be stopped, avoid sudden speed changes, which may initiate tipping or rolling of the sprayer. Do not slam on the brakes when rolling backward, as this may cause the sprayer to overturn.

• Use the seat belt when operating the machine and be certain that it can be released quickly in the event of an emergency.

• Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them.

• Do not remove the rollover protection system (ROPS).

• Reduce speed and load when operating on rough terrain, uneven ground, and near curbs, holes, and other sudden changes in terrain. Loads may shift, causing the sprayer to become unstable.

  Warning

  Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries.

• Reduce your speed when operating on rough terrain and near curbs.

• Grip the steering wheel loosely around the perimeter. Keep your hands clear of the steering wheel spokes.

The weight of the cargo can change the Workman center of gravity and handling. To avoid loss of control and personal injury, follow these guidelines:

• Reduce the weight of the load when operating on hills and rough terrain to avoid tipping or overturning of the vehicle.

• Liquid loads can shift. This shifting happens most often while turning, going up or down hills, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the vehicle to tip over.

• When operating with a heavy load, reduce your speed and allow for sufficient braking distance. Do not suddenly apply the brakes. Use extra caution on slopes.

• Be aware that heavy loads increase your stopping distance and reduce your ability to turn quickly without tipping over.

1. Stop the sprayer on level ground.

2. Use the BOOM-LIFT switches to lower the booms.

   Note: Wait until the booms reach the full, extended spray position.

3. When the booms need to be retracted, stop the sprayer on level ground.

4. Use the BOOM-LIFT switches to raise the booms, until they have moved completely into boom transport cradle forming the “X” transport position and the boom cylinders are fully retracted.

   Important: To prevent damage to the boom actuator cylinder, make sure that the actuators are fully retracted before transporting the machine.

The sprayer is equipped with a boom transport cradle that has a unique safety feature. In the event of accidental boom contact with a low overhead object while in the transport position, the boom(s) can be pushed out of the transport cradles. If this occurs, the booms will come to rest in a near horizontal position to the rear of the vehicle. While the booms will not be damaged due to this movement, they should be immediately put back into the transport cradle.

Important: The booms can be damaged by transporting them in any position other than the “X” transport position using the boom transport cradle.

To put the booms back into the transport cradle, lower the boom(s) to the spray position, and then raise the boom(s) back into the transport position. Make sure that the boom cylinders are fully retracted to prevent actuator rod damage.

Important: In order to ensure that your solution remains well mixed, use the agitation feature whenever you have solution in the tank. For agitation to work, the PTO must be engaged and the engine must be running above an idle. If you stop the vehicle and need agitation on, place the shift lever in the Neutral position, set the parking brake, Engage the PTO, engage the clutch, and set the hand throttle, if equipped.

Note: This procedure assumes that the PTO is engaged (HD-series models with a manual transmission) and the boom section valve calibration has been completed.

1. Lower the booms into position.

2. For the HDX-Auto model, set the SPRAYER-MODE switch as following:

   • When using the sprayer in the manual mode press the switch to the right; refer to Sprayer-Mode Switch (HDX-Auto Model).

   • When using the sprayer in the automatic mode press the switch to the left.

3. Set the MASTER-BOOM switch to the Off position.

4. Set the individual boom switches, as needed, to the On positions.

5. Drive to the location where you will be spraying.

6. Navigate to the Application Rate screen on the InfoCenter and set the desired rate. To do this:

   1. Ensure that the pump is On.

   2. For HD-series models with a manual transmission, elect the desired gear range.

   3. Begin driving at your target ground speed.

   4. For HD-series models with a manual transmission or with a automatic transmission used in the manual mode, verify that the monitor displays the correct application rate. If needed, manipulate the APPLICATION-RATE switch until the monitor displays the desired application rate.

      Note: HD-series models with a automatic transmission that are operated in the automatic mode, the computer will automatically adjust the sprayer pressure to maintain the application rate.

   5. Return to the location where you will begin spraying.

7. Set the MASTER-BOOM switch to the On position and begin spraying.

   Note: When the tank is nearly empty, the agitation may cause foaming in the tank. To prevent this, turn the agitation valve off. Alternatively, you can use an anti-foaming agent in the tank.

8. When finished spraying, set the MASTER-BOOM switch to the Off position to turn off all BOOM-SEGMENT switches, and disengage the PTO lever (HD-series models with a manual transmission).

Important: Before calibrating the sprayer system used on the HDX-Auto model, fill the sprayer tank as required with clean water and operate the machine while spraying at 40 psi or greater for a minimum of 30 minutes.

Note: Before using the sprayer for the first time, if you change the nozzles, or as needed, calibrate the sprayer flow, speed, and boom bypass.

1. Fill the spray tank with clean water.

   Note: Ensure that there is enough water in the tank to complete each of the calibration procedures.

2. Lower the left and right boom sections.

3. For the HDX-Auto model—operate the machine while spraying at 40 psi or greater for a minimum of 30 minutes. Fill the sprayer tank with clean water when finished.

4. Set the protected settings to off; refer to Setting the Protect Settings.

5. For the HDX-Auto model—set the sprayer system to the Manual Mode; refer to Switching between Manual Mode and Automatic Mode.

Operator supplied equipment: Stop watch capable of measuring ± 1/10 second and a container graduated in 50 ml (1 fl-oz) increments.

Note: Calibrating the sprayer flow for machines without a throttle lock requires 2 people.

1. Set the transmission as follows:

   • For HD-Series Models with a manual transmission—shift the transmission to Neutral

   • For the HDX-Auto model—shift the transmission to P (park).

2. Set the parking brake and turn the engine on.

3. Set the PUMP switch to the On position, and turn on the agitation.

4. Press down on the accelerator pedal until you reach the maximum engine speed.

5. Set the engine speed as follows:

   • For machines without the optional throttle lock—have 1 person press down on the accelerator pedal until maximum engine speed is reached.

     Note: The other person will collect samples from the sprayer nozzles.

   • For machines with the optional throttle lock, press down on the accelerator pedal until maximum engine speed is reached and set the throttle lock; refer to operation instructions for your Workman hand throttle kit.

6. Set all 3 boom switches and the MASTER-BOOM switch to the On position.

7. Prepare to perform a catch test using the graduated container.

8. Start at 40 psi (2.75 bar) and use the APPLICATION-RATE switch to adjust the spray pressure so a catch test yields the amounts listed in the table below.
