- Page 10 Winch Mounting It is important to mount the winch securely so the three major sections (the motor end, the cable drum, and the gear housing end) are properly aligned. Excessive bushing wear and difficulty freespooling are usually symptoms of misalignment. If the winch is mid-mounted, attach at least one tie-plate to the mounting feet at the bottom of the winch to maintain alignment.
- Page 11 Cable Installation - Set Screw An "A" or "B" decal on the motor end bearing indicates the spooling direction of the cable. If the decal is damaged or unreadable, contact Customer Service for addition information. 1. Unwind the cable by rolling it out along the ground to prevent kinking. Securely wrap the end of the cable opposite of the hook with plastic or similar tape to prevent fraying.
- Page 12 Sierra Hydraulic Winch Operation Familiarize yourself with winch by making test runs before the first pull. Plan your test in advance. You hear your winch as see it operate; learn to recognize the sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting.
