The allowable tolerance on nominal pressure is
35 kPa (5.1 psi).    Note: The pressures listed in Tables 2 and 3 are normal values for cylinders mounted on a machine. Do not use the pressures if the cylinder is not mounted on the machine or if the belts have been removed.
When testing is complete, remove the 9U-7369 T-Cable from the machine wiring harness and reconnect the monitor in the cab to the machine wiring harness.Changing the Battery Saver Interval
To change the time interval for the battery saver (auto shut-off timer length):
Illustration 7 g02798770
Potentiometer - For Adjusting Auto-Shutoff Time Interval
Remove the back cover and locate the potentiometer shown in Figure 7.
Adjust the potentiometer in a clockwise direction to increase the length of time the unit will stay "ON". The initial setting is 1 minute after the "Press to Test" button has been pressed.
Replace the back cover.Service
If the belt tension tester does not operate correctly or needs repairing, contact Dealer Service Tools. See Section ""Additional Contact Information"".Before sending the tool back for repair, be sure to enclose a letter that describes the problem and include a purchase order number for repair billing. Also, list the date of purchase from Caterpillar. Diagnostic tools have a 1 year warranty and will be repaired at no charge (except for abuse). The cost of out of warranty repairs will be charged to the dealer.
