CAUTION: Solution tank can contain hazardous materials which can cause serious injury or death to you or others. Wear protective clothing, eye wear, and gloves while draining tank. Drain solution in an area where people, animals, vegetation, and water supplies, and so on, cannot be contaminated.

1. Drain solution tank. (See Drain Solution Tank in the Solution System Section.)

2. Completely retract tread for hydraulic tread adjust option, or set manual machines to desired tread setting. (See Set Tread Width procedures in this Section.)

   NOTE: If sticking occurs, remove debris from axle knees and spray with TY25733 teflon based lubricant. Activate tread adjust in and out until free.

3. Place wheel chocks in front and behind the tires that will not be reset at this time.

   CAUTION: Sprayer with spray boom is heavy. To avoid injury or death, only lift and support the sprayer when it is empty. Only jack wheels using supplied lift bracket and support the machine using the JDG11094 sprayer support stand or equivalent. Do not apply jack pressure at any other location on the axle. Lift only one wheel at a time.

   Before jacking a front wheel, turn it fully outward.

4. Raise one corner of the machine with the lift bracket (A) and a jackstand until wheel clears the ground by approximately 152 mm (6 in).
