each lug nut to a torque value of 120 dry
ft.-lbs.
NOTE: Use slow, even pressure on the
torque wrench. Quick or jerky
movements can cause inaccurate
values.

ft.-lbs. and again to 400-500 dry ft.-lbs.
NOTE: If the wheel turns during lug nut
torquing, lower machine to the
ground - just enough for the tire to
touch and prevent rotation. Or, more
preferably, place a suitable wedge
between the tire and the ground.
Lower the machine and resume
operation. Recheck torque after 30
minutes of operation.
