Procedure for Manifold Relief Valve Pressure Check:
1.Make sure hydraulic oil is at normal operating tem- perature by operating the machine for approximately 10 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.Make sure the hydraulic tank is full.
CAUTION
Operate all hydraulic controls to relieve system pressure and avoid injury from pressurized hydraulic oil.
4.Clean hose connection and right hand reel motor. Disconnect the hose leading from the right hand reel motor to port M2 on the hydraulic manifold.
IMPORTANT: Make sure oil flow indicator arrow on the flow gauge is showing that the oil will flow from the hose through the tester and into the motor.
5.Install tester in series with the hose and motor. Make sure the flow control valve is fully open.
6.Make sure backlap knob on the valve block is in the mow position. Make sure reel speed knob is set to posi- tion 9 or greater.
CAUTION
Keep away from reels during test to pre- vent personal injury from the rotating reel blades.
7.Start engine and move throttle to full speed (3200
100RPM). Engage the cutting units.
8.Watch pressure gauge carefully while slowly clos- ing the flow control valve until the manifold relief opens.
9.System pressure should be from 2700 to 3300 PSI.
A.If specification is not met, adjust relief valve.
B.If this specification is met, go to step 11.
10.Adjusting the relief valve pressure as follows:
A.Remove the cap from the relief valve.
B.To increase the relief valve pressure set point, use an allen wrench and turn set screw slightly clockwise.
C.To decrease the relief valve pressure set point, use an allen wrench and turn set screw slightly counterclockwise.
D.Repeat steps 1 through 10 above until the relief valve pressure set point is correct. Reinstall cap on valve when valve is set properly.
E.If the relief valve pressure set point can not be adjusted to specification, go to step 11 and replace the relief valve.
11.Disengage cutting units. Shut off engine.
12.Disconnect tester from manifold and hose. Recon- nect hose to the pump.
