Belt lubrication
Use only 100% silicone and avoid silicone sprays that contain additives and oil
distillates. An ounce of silicone should be used per application.
The running belt should be lubricated every three months (independent of usage) or
every 50 operating hours depending on what occurs first. Even if the treadmill is not
used, the silicone will evaporate after some time and the belt dries out.
Note: Even though the running belt was already lubricated by the manufacturer,
the running mat should be lubricated before first use - just in case the belt dried out
within the production time and the purchase date.
Lubricate the silicone on the underside of the running belt. Do NOT apply it to the
running surface. To do this, put the treadmill upright and apply the silicone to the
inner side of the belt. Spray the silicone downwards and across the belt. Turn the belt
around half-way and repeat the step. About an ounce of silicone should be used for
application.
Note: When you do the belt lubrication, make sure that the treadmill is on a surface
that can be cleaned easily. After you have lubricated the belt, remove excess silicone
from belt and frame.
