SereneLife Treadmill SLFTRD20 Belt Adjustment

Introduction

Although the running belt is pre-adjusted to the running deck, after prolonged use it can stretch and require adjustments.

If your SereneLife Treadmill Belt (model SLFTRD20) has begun to stretch and slip after extended use and requires an adjustment, follow this guide.

The running belt is the most important component that must constantly be centered in order to utilize the Treadmill. If the running belt starts to slide or extend to the side, the treadmill is rendered useless.

Step 2 requires you to ensure that the treadmill belt is running at the lowest speed possible, or else the belt will not be centered. However in step 6, it shows that Treadmill should be turned off before tightening the belt, so don't try to mix up both of these steps.

Before we begin it's important to determine which side the belt is shifting towards.
If the belt is shifting to the right, then turn the right adjustment bolt to turn 1/4 clockwise. If the belt is shifting to the left, then turn the left adjustment bolt to turn 1/4 clockwise.
Place the Allen wrench in the left rear roller bolt.
Turn the left roller bolt adjustment to turn one-fourth clockwise.
Now stop and wait for the belt to begin to center itself.
You must wait for the belt to re-center between each adjustment to ensure that you do not overcorrect the belt.
