CAUTIONS
Protect hoist cable from damage. Do not allow kinks or bends to occur.
Maintain tension on cable at all times. Feed onto cable spool, coil cable into
a suitable container, or onto a protective pad, which will prevent cable
contact with ground or over abrasive surfaces.
LIMIT SWITCH adjusting screws are factory set and any attempt to adjust
will result in component failure.
NOTES
Resetting of LIMIT SWITCH operations is necessary only when:
Cable is fully extended and less than 5-7 wraps remain on drum at full stop.
The limit switch box, roller chain, or winch drum assembly are removed.
A cable installation indicates a failure of any limit switch function.
