4. CAUTION: Sprayer with boom weighs approximately 10,432 kg (23,000 lb). To avoid injury or death to you or others, lift and support an empty machine only. Lift machine using an overhead hoist at proper location or using a 4,082 kg (4.5 ton) jack and appropriate lift bracket. Do not apply jack pressure at any other location on axle. Lift only one wheel at a time. Always support machine with a minimum 6,804 kg (15,000 lb) capacity shop stand.

   NOTE: If an overhead hoist is not available to raise machine, use lift bracket (A), attached with M16 x 80 cap screws, and a floor jack.

   Using an overhead hoist (or jack bracket and floor jack) raise one corner of the machine until wheel clears the ground by approximately 152 mm (6 in.).

5. Position 6,804 kg (15,000 lb) capacity shop stand (B) under frame and lower machine onto support with bottom of tire 76—127 mm (3—5 in.) off the ground.
