Load Handler Pressure Adjustment

The Load Handler Pressur e Relief Valve (REL-2) limits system pressure for the rotate, reach, and retract functions. Perform the following steps to adjust Load Handler system pressure.

1.Turn the key switch OFF and disconnect the battery connector.

2.Remove the tractor cover.

3.Connect a pressure gauge capable of measuring 3000 psi (211kg/cm2) to TP3 on the main manifold. Refer to Figure7-93

Section 7.Component Procedures

Load Handler Pressure Adjustment

4.Loosen the lock nut on the load handler pressure relief valve (REL-2) on the main manifold. See Figure7-93 .

5.Reconnect the battery connector and turn the key switch ON.

6.Rotate the load handler completely CW or CCW. While requesting rotate against the stop, observe pressure. Pressure should be 1500 psi (105.4kg/cm2).

7.Adjust REL-2 for the correct pressure while rotating against the stop.

NOTE: If request exceeds 5 seconds against the stop, the system will shut down.

8.When the pressure is correct, tighten the lock nut on the valve.

9.Turn the key switch OFF and disconnect the battery connector.

10.Remove the pressure gauge.

11.Install the tractor cover.

Traverse Pressure Adjust mentHydraulic Components

Traverse Pressure Adjustment

The Traverse Pressure Relief Valve (REL-3) limits system pressure for the traverse function. Perform the following steps to adjust traverse pressure.

1.Turn the key switch OFF and disconnect the battery connector.

2.Remove the manifold cover located at the top of the mini-mast.

3.Connect a pressure gauge capable of measuring 3000 psi (211kg/cm2) to G1 on the load handler manifold. Refer to Figure7-94

6.Move the traverse control so the load handler is traversed against the wood block. Keep the load handler pressing against the block. Pressure should be 1100 psi (77.3 kg/cm2). If OK, proceed to step 13. If not OK, proceed as follows.

7.Turn the key switch OFF and disconnect the battery connector.

8.Remove the cap from the top of REL-3 to expose internal spring tension adjuster.

NOTE: Cap must be reinstalled before system pressure can be tested.

9.Use a socket head wrench to adjust pressure. Turning CW increases pressure; CCW decreases pressure.

NOTE: 1/4 turn equals approx. 100 psi (7kg/cm2).

10.Reinstall cap removed in step 8.

11.Reconnect the battery connector and turn the key switch ON.

12.Repeat steps 6 thru 11 until pressure is 1100 psi (77.3 kg/cm2).

13.Turn the key switch OFF and disconnect the battery connector.

14.Remove the pressure gauge. Remove the clamp and wood block.

15.Install the manifold cover.

4.Clamp a block of wood against the traverse rack stop. See Figure7-95
