3. Running belt tension adjustment
All treadmills' belts should be adjusted before leaving the factory and after the installation, however, after it is used for a period,
looseness may occur. For example: when users are running, it may occur pause and slip, if which happens, adjust the belt and bolts
synchronously from both the left and right side in a clockwise direction and with semicircle as the unit; if the running belt is too
loose, it may occur slip between the belt and the roller when treading on the belt; but if too tight, it will be easy to increase the
motor load and damage motor, running belt, roller, etc.
4. Running belt deviation adjustment
All treadmills' belts should be adjusted before leaving the factory and after the installation, however, after it is used for a period, it
may occur belt deviation, which is caused by the following reasons:
3. The main engine is not placed evenly.
4. The user's feet are not on the center of running belt.
If the deviation phenomenon is caused by the uneven force of the user's feet, no-load rotation for a few minutes can make it
normal. For deviation phenomenon that can't return to normal automatically, adjust step by step by using 6MM inner hexagon
spanner with the machine and with quarter-circle as the unit. Running belt deviation is not covered in the warranty scope and is
mainly maintained by users according to the instruction book. Deviation phenomenon will severely damage the running belt, so it
should be found and corrected in time.
