Belt / Deck Wear Test; Push Off Test - True Fitness 350-750 Service Manual

Belt / Deck Wear Test

This is a simple physical test to gauge the general level of friction present between the deck and belt.
1. While the treadmill is not running, inspect the condition of the underside of the tread belt. The fabric
should be soft and porous. If the belt appears glazed- replace the belt.
2. While the treadmill is not running, slide your hand under the belt and feel the surface of the deck.
The deck should feel smooth with no abrasions or scratches.
If any abrasions or scratches are found- replace the deck.

Push Off Test

Place the machine in Calibration mode, elevate to the highest elevation- speed should be set to 0. Stand on
the tread belt positioning yourself close to the console; push off with moderate force. The elevation
combined with your weight and the force of the push should cause the belt to carry you all the way to the
end of the machine*. If the test does not carry you to the end of the machine lubricate the belt using True
Fitness liquid silicone. After lubricating the belt/deck perform the push off test again. If it does not pass the
test after lubricating replace the belt and deck
* Note: Residential treadmills may only carry about ¾ of the distance of the deck due to higher tension on
the belt.
