well as the safety of others, please verify that the power source is correct before powering in
the equipment. Any power supply source above or below this level could cause significant
damage to the equipment and/or user.
GROUNDING METHODS:
This elliptical must be grounded. Should the elliptical malfunction or breakdown, grounding
provides a path of least resistance for electric current to reduce the risk of electric shock. This
product is equipped with a plug that has an equipment-grounding conductor and a grounding
plug. The plug must be plugged into an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
This elliptical is for use on a nominal 120V circuit and has a grounding plug (Figure A). Ensure
that the elliptical is connected to an outlet with the same configuration as the plug. Do not use
an adaptor for this product.
CAUTION:
Improper connection of the equipment can result in risk of electric shock. Check with a
qualified electrician or serviceman if you are unsure whether the product has been properly
grounded. Do not modify the plug provided with the product. If it will not fit the outlet, have a
proper outlet installed by a qualified electrician.
WARNING!
1. NEVER use a ground fault circuit interrupt (GFCI) wall outlet with this elliptical.
2. NEVER operate the elliptical using a generator or UPS power supply.
3. NEVER remove any cover on this elliptical without first disconnecting the Power Cord (No. 4).
4. NEVER expose the elliptical to rain or moisture. This elliptical is not designed for outdoor
