EXCEPTION

During rehabilitation where the user is using one leg much stronger 
than the other, it might happen that the running belt drifts to one 
side� In these cases you should not adjust unless the running belt 
does not centre itself during normal condition usage�

Belt tension adjustment

Adjustment must be made from the rear roller� The adjustment bolts 
are located at the end of the step rails in the end caps�

- Tighten the rear roller bolts (clockwise) only enough to prevent 

slippage at the front roller� Turn both running belt tension 
adjustment bolts in increments of 1/4 turn each and inspect for 
proper tension by walking on the belt at a low speed, making sure 
the belt does not slip� Keep tensioning the bolts until the belt 
stops slipping�

- If you feel the belt is tight enough, but it still slips, the problem 

may be a loose Motor drive belt under the front cover�

- Do Not Over-tighten 

Over tightening will cause belt damage and premature bearing 
failure�

Centre the running belt (fig. F-5)

Centre the running belt is needed when your running belt is not 
tracking in the centre of your running surface� This is noticed easily 
when the gap between side landing and running belt is significantly 
bigger on one side compared to the other side�
This can be caused by a few reasons, such as:

REASON 1
You do a workout using one leg more powerful in push off during 
your workout� This causes the belt being pushed aside, but will 
correct automatically when let the running belt run unloaded for a few 
minutes�

REASON 2
Your treadmill is not levelled  horizontally, where gravity pulls the 
running belt slowly to the lowest end of the treadmill� This must be 
corrected by levelling the treadmill correctly� as this cannot be solved 
by any other adjustment�

REASON 3
The running belt is not centred correctly between the front and rear 
roller drum� This needs be corrected by adjusting the running belt 
tracking as described below� 

To adjust the running belt’s tracking use the Allen key being provided 
with your treadmill� 

- Set your treadmill at a speed of ± 5 km/h, not running on it�

- When the running belt is tracking to the right side� 

Turn the left-hand rear roller adjustment bold, located on the rear 
end in a socket in the rear roller cover, counter clockwise for 1/4 
turn�

- When the running belt is tracking to the left side� 

Turn the right-hand rear roller adjustment bold, located on the rear 
end in a socket in the rear roller cover, counter clockwise for 1/4 
turn�

- Await ±2 minutes to give the running belt the time to respond to 

the adjustment before repeating the adjustment steps if needed to 
get to the desired result�

  ‼  NOTE

•  Remember, a small adjustment can make a big difference, so 

make the adjustments with small steps at the time�

The belt may require periodic tracking adjustment depending on use 
and walking/running characteristics� Some users will affect tracking 
differently� Expect to make adjustments as required to centre the 
tread-belt� Adjustments will become less of a maintenance concern 
as the belt is used� Proper belt tracking is an owner responsibility 
common with all treadmills�

 ‼  NOTE

•  Damage to the running belt because of incorrect running-belt 

adjustments is not covered by the products warranty�
