fitness level will be overestimated. Similarly, if you 

underestimate your maximum heart rate, your 

fitness level will be underestimated. 

 To stop the test once you reach the target heart 

rate level, press the BACK/STOP button or stop 

pedaling. The meter will now switch to the test 

result display:

 Aerobic fitness = an estimate of your fitness 

level in your regular effort zone, which gives the 

best indication of the state of your health-related 

fitness.

 MET value = a reading that shows the multiple 

of your maximum oxygen uptake at complete 

rest.

 ml/kg/min = a reading that tells how many 

millilitres of oxygen per kilogram of body weight 

per minute your body consumes.

 l/min = a reading that tells your oxygen uptake 

in litres per minute. Unlike the above values, l/min 

does not take account of the user’s body weight.

 Wmax = an estimate of your maximal exercise 

power, measured in watts.

 W/kg = the ratio of your maximal exercise 

power to your weight.

The equipment requires very little maintenance. 

Check, however, from time-to-time that all screws 

and nuts are tight. 

•

 After exercising, clean the equipment with a soft, 

absorbent cloth. Do not use solvents.

•

 Never remove the equipment’s protective casing.

•

 The electromagnetic brake forms a magnetic field 

that may damage the mechanism of a watch, or the 

magnetic identification strip on a credit or cash card, 

should they come into immediate contact with the 

magnets. Never attempt to detach or remove the 

electromagnetic brake!

•

 The electromagnetic brake is based on 

electromagnetic resistance; resistance level is 

electronically measured and shown as watt reading 

on the display. Due to the measurement system, 

your Tunturi crosstrainer need not be re-calibrated 

when assembled, serviced and used according to 

this Owner’s Manual.

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. 

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.

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.

Please follow these instructions when carrying 

and moving the equipment about, because lifting 

it incorrectly may strain your back or risk other 

accidents:

Always switch the power off and unplug the power 

cord before you start moving the equipment 

around!

For transportation or moving of the device, two 

grown-ups are needed. Remain standing in front of 

the device on each side and take a sturdy grip at the 

handles. Lift the front of the device so as to lift the
