Operating the Sprayer Spraying To operate the Multi Pro WM, first fill the spray tank, then apply the solution to the work area, and finally clean the tank. It is important that you complete all 3 of these steps in succession to avoid damaging the sprayer. For example, do not mix and add chemicals in the spray tank at night and then spray in the morning. This would cause the chemicals to separate and possibly damage the sprayer components.
7. Positioning the Spray Sections Set the master-section switch to the ON position and begin spraying. Note: When the tank is nearly empty, the agitation may cause foaming in the tank. To prevent this, turn the agitation valve off. Alternatively, you can use an anti-foaming agent in the tank. 8. The boom-section lift switches on the sprayer control panel allows you to move the outer spray sections between transport position and spray position without leaving the operator's seat.
Changing the Spray Section Position Using the Boom-Section Transport Cradle Perform the following steps to move the outer spray sections to the SPRAY position: 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.
