Figure 9. Check Gearbox Oil Level
• Verify gearbox cooling tubes are connected
• Verify pump rotation is correct
• Clean the system thoroughly to remove dirt or debris in the piping system
• Check all strainers
• Hydro and vacuum test to verify no leaks
• Fill on board water tank
DO NOT OPERATE PUMP WITHOUT SUCTION STRAINER IN PLACE.

A. Fully close discharge and drain valves.
B. Follow OEM and PTO manufacturer instructions to engage pump PTO.
C. Open tank to pump valve.

30 - 45 SECONDS, STOP AND LOOK FOR AIR LEAKS OR BLOCKED SUCTION HOSE.
D. Prime pump if there is no discharge pressure on Gauge(s).
E. Open any recirculation or cooling lines.
F. Verify safety and throttle interlock indicators (are provided and) are on.
G. Increase speed to obtain desired pressure.
H. Open tank fill (crack valve or 1/8 open) (or set desired autofill level).
I. If discharge pressure gauge bounces (or drops), prime pump again
(to evacuate air).
J. Monitor water tank level during test. Do not run pump dry.
