OPERATION AND ADJUSTMENT
APPLYING SILICONE LUBRICANT
To reduce the friction of the walking belt and minimize wear,
anon-oil-, non-petroleum-base silicone lubricant must be
applied to the walking platform before the treadmill is used.
WITH THE POWER CORD UNPLUGGED, lift each side of
the walking belt and spray lubricant generously onto the
indicated area. Reapply lubricant after every ten hours of
use, or whenever performance decreases. Lubricant is
available at most hardware and automotive stores.
Uni.Sport TM silicone spray is recommended. Silicone Lubricant
PLUGGING THE POWER CORD IN
This product must be grounded. If it should malfunction or break down, grounding provides a path
of least resistance for electric current to reduce the risk of electric shock. This product is equipped with
acord having an equipment-grounding conductor and a grounding plug. Plug the power cord Into an
appropriate outlet that is properly installed and grounded In accordance with all local codes
and ordinances.
DANGER: Improperconnection of the equipment-grounding conductor can result in arisk
of electric shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the
product is properly grounded. Do not modify the plug provided with the product--if it will not fit the out-
let, have a proper outlet installed by a qualified electrician.
This product is for use on a nominal 120-volt circuit, and has agrounding plug that looks like the plug
illustrated in Drawing 1. A temporary adapter that looks like the adapter illustrated in Drawing 2 may
be used to connect this plug to a 2-pole receptacle as shown in Drawing 2 if a properly grounded outlet
is not available. The temporary adapter should be used only until a properly grounded outlet (Drawing
1) can be installed by a qualified electrician. The green colored rigid ear, lug, or the like extending from
the adapter must be connected to a permanent ground such as a properly grounded outlet box cover.
Whenever the adapter is used it must be held in place by a metal screw.
Some 2-pole receptacle outlet box covers are not grounded. Contact a qualified electrician to
determine If the outlet box cover is grounded before using an adapter.
