•After exercising, clean the equipment with a soft, absorbent cloth. Do not use solvents. Sweat may cause corrosion: we recommend therefore that you protect all metal surfaces outside the plastic covers with teﬂon or car wax.

•Never remove the equipment’s protective casing.

•If the equipment is not used for a period

of time, the transmission belt may become temporarily distorted. This can lead to a sensation of slightly uneven pedaling. However, after a few minutes of use the effect disappears as the belt returns to its original form.

NOTE! If the equipment does not function properly during use, contact your Tunturi dealer immediately. Always give the model and serial number of your equipment. Please state also the nature of the problem, conditions of use and purchase date. Despite continuous quality control, defects and malfunctions caused by individual components may occur in the equipment. In most cases it’s unnecessary to take the whole equipment in for repair, as it’s usually sufﬁcient to replace the defective part.
