Page 12: Pre-Delivery Checklist
PRE-DELIVERY CHECKLIST Before releasing the winch to the end user, the following checklist should be reviewed and each item verifi ed. INSPECTION Check gear oil and refill as needed. Lubricate all grease fittings. Inspect winch mounting fasteners and torque as required. Check for loose or missing bolts, pins, keepers and cotter pins. - Page 13 Securely attach the wire rope to the load in such a manner as to avoid damaging the load or rigging. Fully engage the drum clutch (see Drum Clutch Operation). When operating the winch in the pay-out direction, ALWAYS bring the load to a complete stop BEFORE Ensure the band brake is released and engage the winch attempting to shift the motor into high speed mode.
