HOW TO ADJUST THE DRIVE BELT
If the pedals slip while you are pedaling, even while
the resistance is adjusted to the highest level, the drive
belt may need to be adjusted.
To adjust the drive belt, you must remove the seat
post, the post knob, the post cover, the right pedal, the
right lock ring, and the right shield as described below.
To remove the Seat Post (10), loosen the Post Knob
(18) a few turns, pull the Post Knob outward, and
remove the Seat Post. Then, using an adjustable
wrench, remove the Post Knob.

Using a standard (flat) screwdriver, release the tabs

See the EXPLODED DRAWING on page 23.
Remove all of the screws from the Left and Right
Shields (21, 22); there are two sizes of screws in
the shields—note which size of screw you remove
from each hole. Then, gently remove the Right Shield.
Loosen the Adjustment Screw (47). Then, tighten the
Idler Screw (45) until the Drive Belt (59) is tight.
When the Drive Belt (59) is tight, tighten the
Adjustment Screw (47).
Then, reattach the left and right shields, the right lock
ring, the right pedal, the post cover, the post knob, and
the seat post.

Do you have a question about the 831.21813.2 and is the answer not in the manual?
Questions and answers
Belt broke is it worth replacing ?
The manual provides instructions for adjusting the drive belt on the Pro-Form 831.21813.2 but does not mention replacing it. However, since the bike is covered by a 90-day full warranty and the frame has a 5-year warranty, it may be worth checking if the repair is covered. If the bike is out of warranty, replacing the belt could be worth it if the rest of the bike is in good condition and the cost of replacement is reasonable compared to buying a new bike.
