you, the owner, with the necessary information
for completing your own preventive maintenance
and minor repairs. The tools provided in the
owner’s tool kit are sufficient for this purpose,
except that a torque wrench is also necessary to
properly tighten nuts and bolts.

If you do not have a torque wrench available
during a service operation requiring one, take
your machine to a Yamaha dealer to check the
torque settings and adjust them as necessary.
