• Use extra caution when operating the machine on wet surfaces, in adverse weather conditions, at higher speeds, or with a full load. Stopping time and distance increase in these conditions.

• Do not touch the engine or muffler while the engine is running or soon after it has shut off. These areas may be hot enough to cause burns.

• Before you leave the operator’s position, do the following:

  • Park the machine on a level surface.

  • Shift the transmission into the NEUTRAL position (manual) or the PARK position (automatic).

  • Shut off the spray pump.

  • Engage the parking brake.

  • Shut off the engine and remove the key (if equipped).

  • Wait for all movement to stop.

• Never run an engine in an area where exhaust gasses are enclosed.

• Do not operate the machine when there is the risk of lightning.

• Use accessories and attachments approved by Toro only.

Important: To ensure that your solution remains well mixed, use the agitation feature whenever you have solution in the tank. For agitation to work, you must engage the PTO and the engine must be running above an idle. If you stop the vehicle and need the agitation on, place the shift lever in the NEUTRAL position, engage 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 section valve calibration is complete.

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-section switch to the OFF position.

Perform the following steps to move the outer spray sections to the SPRAY position:

1. Park the machine on a level surface.

2. Use the boom-section lift switches to lower the outer sections.

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

Complete the sprayer job, then perform the following steps to retract the outer spray sections into the transport position:

1. Park the machine on a level surface.

2. Use the boom-section lift switches to raise the outer spray sections, until they have moved completely into boom-section transport cradles forming the “X” transport position, and the lift cylinders are fully retracted.

   Important: Release the boom-section lift switch(es) once the outer spray sections have reached the desired position. Running the actuators against the mechanical stops may damage the lift cylinders and/or other hydraulic components.

   

   Figure 91

   “X” transport position

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

The sprayer is equipped with boom-section transport cradles that have a unique safety feature. In the event the spray section accidentally contacts with a low overhead object while in the transport position, you can push the spray section(s) out of the transport cradles. If this occurs, the spray sections come to rest in a near horizontal position to the rear of the machine. While this movement will not damage the spray sections, they should be immediately positioned into the transport cradle.

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

To put the outer spray sections back into the transport cradle, lower the spray section(s) to the spray position and then raise the spray section(s) back to the transport position. Make sure that the lift cylinders are fully retracted to prevent damaging the actuator rod.

1. Park the machine on a level surface, engage the parking brake, shut off the engine, and remove the key.

2. Locate the tank drain valve on the right side of the machine (Figure 92).
