N/A The LED on the start button glows faintly, other LEDs are not on: The machine is in power
saving mode. Hold the START button for one second.
N/A The console display is uctuating or does not light up: Check if the treadmill is correctly
connected to the power supply. Turn the power switch o and back on. Safety key is plug-
ged in. Check all cable connections for correct connection. If the problem is still occurring,
please contact customer service.
N/A The belt does not run in the middle during usage:
First check if the treadmill has a stable position, then follow the operating manual in regards
to tension and adjusting the belt (the deck).
N/A The motor appears to be overloaded or E1 appears after a few minutes of training:
The silicone applied to the deck and belt has dried out and the deck must be lubricated
again with silicone spray.
N/A The running mat slips during usage. The belt must be tensioned after a certain amount
of usage. Follow the belt tensioning and alignment in this manual.
N/A Heart rate uctuates or is not recorded:
Check to see if your hands are moist, if all connections behind the console are correct and if
any cables are damaged. With a chest strap, check the battery status and make sure that all
electrodes are moist and correctly placed below the chest.
N/A Silicone symbol is illuminated on the console:
Lubricate the machine with 100% pure silicone. Then press speed down and START at the
same time until the symbol goes out.
2.4 Care and maintenance
The most important maintenance measure is taking care of the running belt. This
includes the adjustment, tensioning and lubrication of the running belt. Damage
caused due to a lack of care or negligence will not be covered by the warranty. Thus,
check for maintenance in regular intervals. Be extremely careful when adjusting and
tightening the belt, because a strong over or under tension may lead to damage. The
running mat is set properly in the factory before delivery. However, the running mat
may get out of place during transport.

Adjustment of the running mat
+During training, the running belt should run as centered and straight as possible.
The alignment of the running belt may change depending on the stress and load.
Another reason can be the positioning of the equipment on an uneven surface.
+While adjusting the belt, let the equipment run with a speed of approximately
5km/h. Nobody may be on the equipment during this process.
+If the running belt drifts o to the left, turn the left setting screw on the rear end of
the equipment at most 1/4 rotation clockwise and the right setting screw at most
1/4 rotation counterclockwise (g. C).
+If the running belt drifts o to the right, turn the right setting screw on the rear
end of the equipment at most 1/4 rotation clockwise and the left setting screw at
most 1/4 rotation counterclockwise (g. D).
+Then watch how the belt runs for approximately 30 seconds, because the change
will not be visible immediately.
+Repeat the process until the running belt runs straight again. If the running mat
cannot be adjusted, please contact the contract partner.
+If the running mat (belt) cannot be adjusted, please contact Sport-Tiedje.
Tensioning the running belt again
+If the running belt slips over the rollers during operation (if this is the case, a
noticeable jerking will be noticed while running), the running belt must be
tensioned again. In most cases, the cause for the slipping is a straining of the belt
through usage. This is completely normal.
+It can be tightened through the same setting screws that were used during
adjustment.
Move the belt to the right Move the belt to the left

TR20
15
+While tightening the belt, let the equipment run at a speed of 5km/h.
+Turn the left and right setting screws directly after each other a max. 1/4 clockwise
rotation.
+Then check if the running belt is still slipping. If this is the case, you must repeat
the described process.
Lubrication of the running belt
+If the running belt is inadequately lubricated, the friction will increase signicantly
and this leads to strong wear of the endless belt, running panel, motor and circuit
board.
+If you feel an increase in friction from the running belt, this is an indicator that you
should lubricate the belt (however, a lubrication should be done at least every 3
months).
+ The treadmill has a reminder for lubricating the treadmill:
A symbol is displayed on the console every 100 operating
hours. The symbol appears on the display for 5 minutes
and then turns o. In order to turn o the symbol
prematurely, press the INCLINE up and INCLINE down
buttons at the same time.
+In order to be able to optimally lubricate
the treadmill, the running belt must be
lifted slightly. Then apply some silicone
spray (free of grease) on the entire
running deck. It is easiest to lubricate
when the treadmill is folded up. Apply
three short (approximately 1 second)
sprays of silicone lubricant between the
belt and the running deck.

3 ASSEMBLY
3.1 Package contents
The package contains the parts represented in the illustration, including a power
cable with mains plug. If one of the illustrated parts is missing, please contact your
contract partner.
+The spraying tube should be held sideways in order to guarantee a moistening of
the entire underside of the belt. Continue to rotate the belt by hand so that the
entire area between the endless belt and running deck is lubricated. Wipe o the
excess lubricant.
+This maintenance must also be done after the equipment has not been used for a
longer period of time.
2.5 Maintenance and service calendar
The cockpit, casing, handrails and entire frame must be
cleaned after every training session with a moist towel
(no solvent!) in order to avoid damage caused by sweat.
After 150 hours of operation, the maintenance symbol
reminds you to clean the treadmill. After you have
cleaned the treadmill and checked all components, turn
o the symbol by simultaneously pressing the INCLINE up and INCLINE down buttons.
The following routine work must be done in the specied time intervals:

3.2 Assembly instructions
Check the equipment for possible damage after unpacking. If it is damaged or parts
are missing, please contact our customer service.
1. Since the treadmill is very heavy, we recommend initially removing the upper cover
of the packaging; fold the sides downward. Then you do not have to remove the
treadmill from the box.
2. Remove all parts from the box before you start the assembly. Remove the plastic
and place all parts in front of you on a surface. Keep the oor under the treadmill free
of objects. The rear part of the treadmill may have to be lifted in order to be able to
get under the parts better.
Before assembly, take an exact look at the individual illustrated assembly steps and
execute the assembly following the specied order.
