Vision Fitness T9500 - Manual (Page 32)

Running speed is not stable
Possible causes:
1. AC power voltage is too low.
2. Tension of drive belt or running belt is too loose.
3. Poor adjustment of MCB.
4. MCB is damaged.
5. Motor is damaged.
Fix:
1. Check the power voltage by using voltage-meter to see if it is within 120V
15% or 230V 15%.
If the power voltage isn't within the range, look for a qualified
electrician for help.
2. Open the motor cover, if the belt has stretched and is slipping across the
rollers when running.
Adjust the belt tension.
3. Remove the motor cover and run the
machine at low speed, then adjust the IR
COMP of MCB.
If it hasn't been improved, replace new
MCB.
4. Replace new motor.
