Ploy V-Belt looseness and tightness adjustment
The ploy V-Belt will gradually loosen and change its shape after a long time use, and you need to
adjust it for safe use. How to determine: when you are running as usual, when you stamp with your
feet on the running belt, if you feel kind of pause sometimes, it indicates the V-Belt or running belt
is loose somehow, and you need to make a further confirmation. Which part is loose: use a coin
to unlatch the turn lock on the motor cover and turn it by 90 degrees, this way the motor cover
opens. Then let the treadmill work at a speed of 1km/h. Stand on the running belt, grab the foam
handrails and try to press the running belt harder with your feet. (We suggest to stamp with your
own body weight)
A) If the running belt doesn't stop when you press it, then the running
belt and motor belt arenot flabby or not tight. They are just right.
B) If the running belt stops when you press it, but the front roller and V-belt don't stop, then
the running belt is a little loose, and you need to adjust the running belt for safe use (to
adjust running belt loose and tightness, see the maintenance guideline in the previous page).
C) If the motor belt and running belt stops when you press the running belt, the motor still runs,
then the V-belt is flabby, you need to adjust it for safety of use.
ADJUSTMENT METHOD
Step 1: use a coin to unlatch the turn lock on the motor cover and turn it by 90
degrees, this way, you take off the protector cover. When the motor cover is open, the motor cover
will rise naturally.
Step 2: Unscrew the four bolts of the motor base (do not remove it) and adjust the adjusting
bolt on the motor base with a wrench according to the condition. You can use your hands hand
to reverse the motor belt which is between motor axis and front roller, if it is too loose, you can
reverse the Ploy V-Belt by 100%. If it is too tight, the degree you can turn the V-belt is very limited.
After the adjustment, if you can reverse the motor belt by about 80%, then the motor belt is just
right. Please adjust the V-belt tightness so it can be turned by 80%.
Step 3: Lock the motor base frame and lock the motor cover with the coin.
