underneath them when tightened. If they are not flat and tight they will
become loose very quickly.

diagram above. Use only genuine Timberwolf nuts and washers, as they
are of a higher grade than normally stocked at fastener factories. Failure
to use the appropriate grade nuts or washers may result in damage, injury
or death. The use of genuine Timberwolf blades and bolts is recommended.
14 Apply a smear of anti seize compound (copper ease) to the bolt threads and
back face of the nuts. Do not apply copper grease onto the counter bore
faces of the blades or bolts.

setting of 125 lbs ft (170 Nm).

repeat steps 6 - 14.
