Solution/Cause
1. Tether cord not in position.
2. Circuit breaker on front grill tripped. Push circuit breaker in
until it locks.
3. Plug is disconnected. Make sure plug is firmly pushed into
115 VAC wall outlet.
4. Breaker panel circuit breaker may be tripped.
5. Treadmill defect. Contact your Spirit Fitness dealer.
The user may be walking while favoring or putting more weight
on either the left or right foot. If this walking pattern is natural,
track the belt slightly off-center to the side opposite from the
belt movement. See General Maintenance section on Tread-
belt Tension. Adjust as necessary.
1. If the belt moves, but stops after a short time and the
display shows "LS", run calibration.
2. If you press start and the belt never moves, then the
display shows LS, contact service.
Need to replace the breaker with a "High In-rush current" type
breaker (see page 3 for details)
