minutes.
2. Make sure machine is parked on a level surface with
the cutting units lowered. Make sure engine is off and
the parking brake is engaged.
3. Read Precautions for Hydraulic Testing.
4. Disconnect hose connection on the reel drive pump
leading to port P1 on the hydraulic manifold.
5. Install tester in series with reel drive pump and the

9. Watch pressure gauge carefully while slowly clos-
ing the flow control valve until 2000 PSI is obtained.
Verify with a phototac that the pump speed is as speci-
fied in step 8.
10. Flow indication should be 5.5 GPM minimum.
11. Shut off engine.
12. Disconnect tester from manifold and hose. Recon-
nect hose to the pump.
13. If flow was less than 5.5 GPM or a pressure of 2000
PSI cannot be obtained, check for restriction in the pump
intake line. If line is not restricted, remove pump and re-
pair or replace as necessary.
