Q: What air supply do I need for the CP7748?
A: Use a clean, regulated 90 psi air source with a 3/8 in (10 mm) hose and 1/4 in NPT inlet fittings. Adequate flow (up to ~25 cfm at tool max) ensures full torque.
Q: How does “max torque” differ from “working/fastening torque”?
A: Max (reverse) torque is the peak breakaway capability, while working/fastening torque reflects typical tightening levels; for this model it’s up to ~555 ft-lb. Always finish critical fasteners with a calibrated torque wrench.
Q: Is the CP7748 suitable for daily tire work in a dealership?
A: Yes—its compact size, high reverse torque, and one-handed ring control make it ideal for rapid wheel removal and general service tasks on light vehicles.
Q: What maintenance is recommended?
A: Follow the operator’s manual: lubricate the tool with quality pneumatic oil, ensure clean/dry air, and periodically check the inlet filter and couplers.
