Tightening Fasteners

Use the correct amount of torque when
you tighten fasteners on the machine.
Applying excessive torque may damage
the fastener or component and not enough
torque may cause a leak or component
failure.
The tightening torque in
the Standard Torque
Chart should be applied
only to the bolts with a "7" head.
(JIS strength classification: 7T)
• Apply 60% torque to bolts that
are not listed.
• Apply 80% torque when
tightened to aluminum alloy.
