(22 N) is applied midway on the top span.
1. Park the machine on a level surface, set the parking
brake, turn the ignition off, and remove the key.
2. Loosen the steering pump mounting bolts (Fig. 50).

lubricate the clutch as follows:
1. Stop the engine, remove the key, and set the parking
brake.

getting off of the sprayer.
• Block the tires when the sprayer is on a jack.
