BASIC TROUBLESHOOTING
PROBLEM: The belt does not move or moves
briefly, but the console works.
SOLUTION: Verify the following:
• Make sure you are following the recommendations and
power guidelines on pages 4 and 5 of this TREADMILL
GUIDE. The unit should be on a dedicated 15-amp circuit
and not on a GFCI-equipped outlet. Do not plug the machine
into a power strip/surge protector or extension cord.
• Check for any belt movement. If so, make note of
how far or how long it moves before stopping.
• Try to move the belt by hand. If not, the drive belt may
have come off or the motor bearings may have seized.
• Turn the treadmill off and unplug it from the outlet. Remove the
plastic motor cover located in front of the machine by taking out
the Phillips screws. Check the drive belt for proper alignment.
• With the cover still off, check over the wire and cable connections,
as they may have become loose or disconnected during
shipping or assembly. Make sure connections are secure and
no wires are crimped, damaged, disconnected or burnt.
