Disconnect hose assembly (1) from the adapter assembly on the rotator. Disconnect hose assembly (2) from the adapter assembly on the rotator. Plug or cap the adapter assemblies in order to prevent contamination.
Install Tooling (A) and Tooling (B) between the two hose assemblies in Illustration 1 for the jaw circuit. Close the valve on the flow meter in order to check pressure.
Start the engine of the host machine and operate the machine until the hydraulic oil reaches normal operating temperature.
Open the jaw of the work tool. Close the jaw and continue to hold the control in the CLOSE position in order to allow the cylinder to stall. Observe the pressure on the gauge. The pressure should be 22500 2500 kPa (3263 363 psi). If the pressure is not within the specification, the pressure must be adjusted accordingly. Refer to the Service Manual for the host machine for the proper procedure.
After adjustments have been made, stop the engine on the host machine and relieve the hydraulic pressure.
Start the engine of the host machine and operate the machine until the hydraulic oil reaches normal operating temperature.

Ensure that the control is selected for the corresponding direction of the flow meter. Tooling (C) will measure flow in either direction.
Operate the control on the host machine for the jaw circuit. Observe the flow on the meter. Refer to Table 2 for the flow specification. If the flow is not within the specification, the flow must be adjusted accordingly. Refer to the Service Manual for the host machine for the proper procedure.

After adjustments have been made, stop the engine on the host machine and relieve the hydraulic pressure. Remove the tooling and install the two hose assemblies.
The air must be purged from the work tool before operation. Refer to Service Manual, "Hydraulic System Air - Purge" for the proper procedure.Rotate Circuit
