1.2 Personal safety
+Before you start using the equipment, you should consult your physician that this type of
exercise is suitable for you from a health perspective. Particularly aected are persons who: have
a hereditary disposition to high blood pressure or heart disease, are over the age of 45, smoke,
have high cholesterol values, are overweight and/or have not exercised regularly in the past year.
+Please note that working out excessively can seriously damage your health. Please also be aware
that heart rate monitoring systems might be imprecise.
+The equipment may only be used for its intended purpose; that means for whole body workouts
for adults.
+Any other usage is prohibited and potentially dangerous. The contract partner cannot be held
liable for damage resulting from improper use.
+The equipment is strictly for use by one person at a time.
+Children should not be allowed unsupervised access to the equipment.
+Before starting your training, make yourself familiar with all of the equipment‘s functions and
setting options. Have an expert explain the correct usage of the product to you.
+Make sure that nobody is in the range of motion of the equipment while exercising.
+Keep your hands, feet and other body parts, hair, clothing, jewelry and other objects well clear of
moving parts.
+During use, wear suitable sports clothing rather than loose or baggy clothing. When selecting
sports shoes, think about the suitability of the sole – preferably this should be made of rubber or
other non-slip materials. Shoes with heels, leather soles, studs or spikes are not suitable. Never
work out in bare feet.
+It is also important to take note of the information given in the workout instructions for creating
a workout plan.
+At the rst signs of weakness, nausea, dizziness, pain, diculty in breathing or other abnormal
symptoms, stop your workout immediately and, if necessary, consult your physician.
+Without prior agreement from your authorized contract partner, opening the equipment is
prohibited.

1.3 Electrical safety
+The equipment requires a 220 - 230V / 50 Hertz mains power supply.
+The equipment should be connected directly to a grounded plug socket only by means of the
power cable supplied. The use of multi-socket adapters or similar is not recommended. Extension
leads must comply with local electrical safety guidelines. Always fully unwind the power cable.
+The outlet should be secured with a fuse with a minimum value of„16 amperes, slow“.
+In order to reduce the risk of an electric shock, always unplug the equipment from the mains
socket immediately after your workout, before assembly or dismantling, and before maintenance
or cleaning. Do not pull on the cable.
+When plugged in, do not leave the equipment unattended at any time. To avoid use by anyone
unfamiliar with the operating instructions, the power cable should be removed when the
equipment is not in use.
+Keep the power cable away from heat, oil and sharp edges. Do not route the power cable
underneath the equipment or under a carpet or rug, and do not place any objects on top of it.
+Make no modications to either the power cable or the mains plug.
+If the power cable or the plug are damaged or defective, contact your authorized contract
partner. Do not use the equipment in the meantime.
+Do not keep electrical devices (e. g., mobile phones) in close proximity to the console or the
control electronics, otherwise display values (e. g., pulse measuring) could be inaccurate.
1.4 Set-up place
+The equipment should only be used indoors, in a suciently heated and dry area (ambient
temperature between 10°C and 35°C). The equipment should not be used outdoors or in rooms
with high humidity (over 70%) like swimming pools. The equipment should only be stored in
surroundings with an ambient temperature between 5°C and 45°C.
+The training room should be well ventilated during training and not be exposed to any draughts.
+Choose a location in which to place the equipment such that there is enough free space/
clearance to the front, the rear and to the sides of the equipment (at least 1.50 m). Furthermore,
the equipment should not be set up in main entrances or on escape routes.
+Always keep the power cable away from hot surfaces and grounds and make sure that the cable
is not stuck somewhere or becomes a„trip hazard“.
+No objects of any type should be inserted into the openings of the equipment.
+The equipment should be placed on a level and solid surface, any unevenness in the oor should
be leveled out.
+A oor protective mat / equipment underlay can help to protect high-quality oor coverings
(parquet, laminate, cork, carpets) from dents and sweat and can help to level out slight
unevenness.

length is displayed on the console and can be adjusted at any time while training.
Certain muscle groups are used dierently through dierent stride lengths. This can also be achieved
by adjusting the resistance or the user bends down while holding on to the handles.
Note: If the stride length motor is activated, you will hear how the motor adjusts the stride length
and then locks.
