only be lubricated with a very thin film of ANDERSEN WINCH GREASE. It is very important
that pawls can move freely.
IMPORTANT: When assembling the winch, check the functioning of each pawl by pushing the
pawl against the spring. The pawls should move smoothly and automatically return to their normal
position, where the pawls engage with the teeth. If the pawls do not function correctly, clean and
lubricate the pawls and gears. Check the function of the pawls again to make sure that it works
correctly. If the pawls do not work correctly replace the springs and recheck the function.
Malfunctioning pawls may lead to unexpected failure of a loaded winch resulting in material
damage or fatal personal injury.
