Assemble in reverse order. During assemble, lightly grease all gear teeth, drive shaft, roller
bearing, shafts, balls, pawls, springs and composite bushings. Use a small, soft brush.
Pawls may be lubricated with either 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 functioning.
Not properly functioning pawls may lead to unexpected release of the winch force resulting in fatal
injuries to the user and others.
