Based on ramp technician feedback, here are frequent mistakes—and how the manual solves them:
| Problem | Manual Solution (Section) | |-------------------------------------------|-------------------------------------------------------------| | Cup won’t close fully | Clean dirt from cup slide rails (Section 5.3.1). Then recalibrate close limit switch. | | Tug drives slowly in reverse | Check proportional relief valve pressure (Section 5.7 – set to 1,800 psi reverse). | | Steering feels loose | Adjust steering orbital valve (Section 3.11 – tighten set screw 0.5 turn). | | Aircraft wheel slips inside cup | Replace rubber friction pads (Section 4.2.2). Torque bolts to 22 ft-lbs. |
