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 machine, training material, engine manual, and all labels on the Workman machine.

• Establish your own special procedures and work rules for unusual operating conditions (e.g., slopes too steep for machine operation). Use the third high lockout switch if high speed could result in a safety or machine 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 machine 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 machine 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 that they work properly. If they do not, drive slowly while putting light pressure on the brake pedal. This dries the brakes out.

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

• Do not accelerate quickly or suddenly apply 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 takes longer than stopping on level ground. If the machine must be stopped, avoid sudden speed changes, which may initiate tipping or rolling of the machine. Do not suddenly apply the brakes when rolling backward, as this may cause the machine to overturn.

• 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.

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.

Perform the following steps to move the booms to the spray position:

1. Park the machine on a level surface.

2. Use the boom-lift switches to lower the booms.

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

Complete the sprayer job, then perform the following steps to retract the booms into the transport position:

1. Park the machine on a level surface.

2. 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, you can push the boom(s) out of the transport cradles. If this occurs, the booms come to rest in a near horizontal position to the rear of the vehicle. While this movement will not damage the booms, 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 damaging the actuator rod.

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, 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 boom section valve calibration has been completed.
