Using Hydraulic Spray Pumps

1. Follow spray pump manufacturers recommendations for pump model selection, setup and operation.

NOTE: Select the smallest displacement motor recommended for multiple hydraulic function operation. The smaller displacement will lower total hydraulic flow demand and improve overall system performance.

3. Connect motor pressure line (A) to retract port of SCV (right-hand side).

NOTE: Use of SCV 3, 4, or 5 for standard hydraulic system is suggested. Use SCV 4 or 5 for High Flow hydraulic system.

4. Connect return line (B) to power beyond return coupler (E).

5. Activate SCV by moving lever forward to retract detent position and adjust hydraulic flow rate per pump manufacturers guidelines.

6. Shut off spray pump by moving SCV control lever to float position (full forward and down). Stopping spray pump by moving SCV to neutral position will cause high pressure oil to be trapped between SCV and pump. This may cause damage to spray pump seals. This applies to motors using the SCV pressure and return couplers.

IMPORTANT: Some motors are not equipped with over-speed protection. Extended operation above recommended speed can cause failure.
