WINCH MAINTENANCE
TROUBLESHOOTING
• All moving parts within the electric winch have been lubricated using high temperature lithium grease at the factory. No further internal
lubrication is required for the life of the winch.
•If using steel cable, lubricate the steel cable periodically using light penetrating oil
• Electrical connections may corrode over a period of time due to environmental changes. This may result in reduced performance of the winch
or even possible electrical shorting. Hence, always clean the electrical connections before and after using the winch.
•After every use of the winch, inspect the steel cable/synthetic rope for damages such as kinks, broken strands etc. When damaged, replace the
cable immediately.
