Failure to comply with these Warnings, may cause
extensive equipment damage and severe personal injury.
2.4.1. Precautions
The electrical supply requirements of your ST-LAB Sure Torque are designed to meet your individual
specifications. Therefore, the Owners Fact Sheet in this manual should be checked before any electrical connections
are installed, or power is put to the unit.
2.4.2. Connections
All electrical connections should be made by a qualified electrician and in accordance with the local electrical
codes.
2.5. Pneumatic Installation
Individual regulators have been provided by ST (refer to Figure 1-3, ST-LAB Torque Tester Pneumatic Diagram).
Filtering systems for air supplies are the machine owner’s responsibility. Contaminated air will cause excessive
wear, erratic operation, and eventual failure of pneumatic components.
2.5.1. Air Supply
A clean and moisture-free air supply of 80 psi should be available to mate with the existing air connection on your
machine. Sure Torque recommends the use of a 5µ filtration.
2.5.2. Plumbing
Customers piping for the air supply can run to the rear of the machine from any convenient point.
2.5.3. Air Pressure Settings
Normal pressure setting for operation is 80 PSI. The automatic pressure switch will shut down machine if inlet
pressure falls below 65 PSI.
2.6. Machine Tuning Sheet
(Refer to the Machine Tuning Sheet in the Appendix-A, accompanying this manual). The Machine Tuning Sheet
shows the recommended mechanical adjustments for the different change parts ordered with your machine. The
Tuning Sheet is a valuable tool for all those operating the ST-LAB Sure Torque Unit. It is recommended that this
tuning sheet be reviewed by All personnel involved in machine operation and change-over procedures, before
initiating machine start-up. Sure Torque should be contacted immediately if there are any questions or problems
pertaining to any specific Tuning Sheet data, its understanding, or application.
The final run and fine tune settings for your machine, may be slightly different from the ones on the Tuning
Sheet, thus, the customer’s set-up and change-over personnel should note these changes, for future
reference, on the Tuning Sheet.
