MALFUNCTIONS
NOTE! 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 device in for repair, as it's usually sufficient to replace the defective part. Always give the model, serial number of your equipment and in case of malfunctions also conditions of use, nature of malfunction and any error code.
When you encounter unusual behavior from the treadmill, simply turn the power switch off, wait 1 minute and turn the power switch on to reset the treadmill. This should clear incidental errors and ready the treadmill for normal operation again. If after you have reset the treadmill by turning the power switch off and on again, and the treadmill is still not operational, contact your local Tunturi dealer for service.
If you require spare parts, always give the model, serial number of your equipment and the spare part number for the part you need. The spare part list is at the back of this manual. Use only spare parts mentioned in the spare part list.

OVERLOAD PROTECTOR
If the treadmill’s power consumption becomes too great, the overload protector will cut the power supply as a safety measure. The fuse button next to the power switch will spring up. Before you continue using the equipment, first check the lubrication of the track, as well as any other mechanical reason that could have caused the overload protector to cut in. Push the fuse button down. The treadmill is now ready for use again.
