fhe
tables shown below give correct torque values
for
various bolts and capscrews. Tighten all bolts
to
the torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt
orque chart
as
a guide. Replace hardware with the same strength bolt.

Torque figures indicated above are valid for non-greased
or
non-oiled threads and heads unless other-
wise specified. Therefore,
do
not grease
or
oil bolts
or
capscrews unless otherwise specified in this
manual. When using locking elements, increase torque values
by
5%.
Torque value for bolts and capscrews are identified by their head markings.
