Toyota Coaster 2015 Owner's Manual page 121

Apply small amount of engine oil to the
grooves of the inside of the stop bolts.
Be careful that engine oil is not applied
to any other part of the bolt, as it may
cause the wrench to slip off when you
tighten the bolts.
CAUTION
To avoid a serious accident, apply en-
gine oil to the grooves of the stop
bolts and the wheel nuts. No matter
how much you try to tighten them,
the nuts may not be securely tight-
ened and the wheels may fall off.

Reinstall the stop bolts and tighten each
bolt a little at a time in the order shown.
Repeat the process until all the bolts are
tight.
Use only the wheel nut wrench to tighten
the bolts. Do not use other tools or any
additional leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the bolt.
