Hobart/Miller.

Some states in the U.S.A. do not allow limitations of how long an
implied warranty lasts, or the exclusion of incidental, indirect,
special or consequential damages, so the above limitation or
exclusion may not apply to you. This warranty provides specific
legal rights, and other rights may be available, but may vary from
state to state.

In Canada, legislation in some provinces provides for certain
additional warranties or remedies other than as stated herein,
and to the extent that they may not be waived, the limitations and
exclusions set out above may not apply. This Limited Warranty
provides specific legal rights, and other rights may be available,
but may vary from province to province.
