Spirit XT385 Owner's Manual page 31

If the belt is too close to the right side, turn the bolt counterclockwise. The belt may require periodic
tracking adjustment depending on use and walking/running characteristics. Some users may affect
tracking differently. Expect to make adjustments as required to center the tread-belt. Adjustments will
become less of a maintenance concern as the belt is used. Proper belt tracking is an owner
responsibility common with all treadmills.

BELT ADJUSTMENTS
Tread-belt Tension Adjustment - Belt tension is not
critical for most users. It is very important though for
joggers and runners in order to provide a smooth,
steady running surface. Adjustments must be made
from the rear roller with the 6mm Allen wrench
provided in the parts package. The adjustment bolts
are located at the end of the step rails as shown in
the diagram below.
Tighten the rear roller enough to prevent slippage at the front roller. Turn the tread-belt tension
adjusting bolts 1/4 turn each and inspect for proper tension by walking on the belt and making sure it is
not slipping or hesitating with each step. When an adjustment is made to the belt tension, you must be
sure to turn the bolts on both sides evenly or the belt could start tracking to one side instead of running
in the middle of the deck.
DO NOT OVERTIGHTEN – Over-tightening will cause belt damage and premature bearing failure. If you
tighten the belt a lot and it still slips, the problem could actually be the drive belt - located under the
motor cover - that connects the motor to the front roller. If that belt is loose it feels similar to the walking
belt being loose. Tightening the motor belt should be done by a trained service person.
DECK LUBRICATION PROCEDURE
To ensure the longevity and proper functioning of your treadmill, proper belt maintenance is required.
You should regularly check between the treadmill belt and the top of the treadmill base for proper
lubrication, and to ensure that no dirt or debris has become trapped. Keeping the deck clean and
lubricated at the recommended intervals ensures the longest life possible for your unit. Should
lubrication dry out, or dirt become trapped, the friction between the belt and deck increases. Increased
friction places undue stress on the drive motor, drive belt, and electronic motor control board which
could result in catastrophic failure of these essential, expensive components.
Failure to clean and lubricate the deck at regular intervals may void the warranty.
As a part of your routine maintenance schedule, belt lubrication and cleaning should be performed
every 90 days, after 90 hours of use, or earlier if you notice that the deck is dry or dirty. Please also be
sure to check belt lubrication before first use.
Do not lubricate with anything other than Spirit Fitness-approved lubricant. Your treadmill comes with
one tube of treadmill belt lubricant.
To lubricate your treadmill belt:
1. Ensure that your treadmill is off and unplugged to minimize the risk of injury.
2. Reach between the belt and the top of the treadmill base to verify that lubrication is present.
