Using Hydraulic Spray Pumps

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

NOTE: Select the smallest displacement motor recommended for multiple hydraulic function operation. 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).

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

Spray Pump (Less Hitch)

5. Some hydraulic motors have a separate case drain line for internal leakage. This line must be routed to the hitch frame drain port to direct oil to sump (zero back pressure.)

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

7. 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 also applies to other 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.
