SECTION 7: FINISH & TEST
7.0 FINISH & TEST
Before starting this section, position the machine in the “Oil Level Check” position as
suggested by the excavator machine manufacturer. Check the oil level sight gauge
on the hydraulic tank. Add hydraulic oil if necessary (refer to the carrier machine
service manual for further information).
•
Check the hose clamp assemblies and valve mounting bolts are tightened as
per the Torque Setting of Metric Bolts & Nuts Chart (Fig 9.0.1)
•
Starting at the coupler end thoroughly check that the hose connections are tightened through
out the complete circuit as per the JIC (SAE 37º FLARE) Connection Chart (Fig 9.1.1).
•
Clear all personnel and all obstacles from the swing radius area and working parameter of the
machine.
• From the seat of the excavator, start the machine and lower the excavator arm to near the
ground. In a very slow motion, using the excavator levers, raise the dipper arm and rotate the
coupler through full rotation. Then raise the boom of the excavator and motion the dipper arm
cylinder to full extension. Now motion the dipper arm cylinder to full retraction, lowering the
boom arm in unison. Use this process to check the hose routing throughout the complete circuit.
Ensure that the hoses are not under any strain or subject to potential jamming or pinching.
Assistance will be required to do this. Modify hose routing if required.
•
Running the machine at idle or a low engine RPM setting to supply a low volume of oil through
the circuit. Activate the circuit and check for any leaks. Shut down the machine immediately if
leaks are detected, then tighten coupler as required and re-check.
•
Activate the circuit several times to ensure that the system is working correctly – refer to the
I-Lock Coupler Operators Manual.
•
Once the test procedure has been completed, touch up paint any welded brackets or assemblies
and cable tie any loose hoses.
• Affix “In Cab” Decals in a suitable location within the operators working area. (See section 8.0
In Cab Decals)
Before using the I-Lock Coupler carefully read the
I-Lock Coupler Operators Manual thoroughly.
