Tensioning The Running Belt - True TC400 Owner's Manual

TENSIONING THE RUNNING BELT

If there is a slipping or jerking sensation when running on the treadmill, the running belt may require tightening. In most
cases the belt has stretched from use. Tensioning the belt takes a few simple adjustments. If you are unsure about this
procedure, contact TRUE product support:

IMPORTANT! Damage to the running belt due to improper belt adjustments is not covered under warranty.
CAUTION:
!
• Verify the treadmill is level before attempting any belt adjustments. An unstable unit may cause belt misalignment.
• Special care must be taken when tensioning the running belt. Turn off the treadmill while adjusting or working near the
rear roller. Remove any loose clothing and tie back your hair. Be very careful to keep your fi ngers and any other object
clear of the belt and rollers, especially in front of the roller and behind the deck. The treadmill will not stop immediately
if an object becomes caught in the belt or rollers.
• For your safety, use the power switch to turn off the treadmill before making any adjustments. Do not adjust the
running belt when someone is standing on the unit.
• Do not turn the adjusting bolt more than ¼ turn at a time. Over tightening the bolt can damage the treadmill and over
stretch the belt.
• If you tighten the belt and it still slips, the problem could actually be the drive belt, which is located under the motor
cover and connects the motor to the front roller. If the drive belt is loose, it feels similar to the walking belt being
loose. Tightening the drive belt should only be done by a trained service person, contact TRUE product support for
assistance.
To tension the running belt:
1. Press the Stop key.
2. Turn the treadmill off .
3. Rotate the running belt by hand so the four horizontal tick
marks are visible.
4. Measure the distance between the tick marks on each side of
the machine. The span should be at least 36" (91.44 cm) but
no greater than 36¼" (92.08 cm) on each side.
5. If the belt needs to be adjusted, locate the adjustment bolts in
the rear end caps of the treadmill.
6. On each side of the machine, turn the adjustment bolts
clockwise ¼ turn and remeasure.
7. When both sides are measuring within range, turn the
treadmill on and start the belt at 3 mph (5 kph) keeping off the
unit.
8. Allow 2 minutes for the belt to self adjust.
9. Check to see if the belt is still slipping.
Repeat these steps if additional tensioning is needed.
