Running Belt/Deck Maintenance
The running belt and deck will need to be cleaned and the belt may
need minor adjustments. Use the following two sections to keep
your 400T operating properly.
Cleaning the Belt and Deck Surfaces
To minimize the effect of friction between the wood deck and the
running belt, we recommend cleaning the underside of the running
belt and the top of the running deck surface by wiping them with a
clean dry towel. This simple procedure should be done to prevent
premature wear of the deck, running belt, and the drive motor system.
Running Belt Adjustments
You may need to adjust the running belt after the first few weeks of
use. All running belts are properly set at the factory, but they may
stretch or become off-center after use. Stretching is normal during
the break-in period, and before long, your belt will reach its optimal
length.
When you set up the 400T, you checked for the proper tension and
centering of the belt. The following section describes how to adjust
the belt tension. If you adjust the tension during the first few weeks,
you should do so on an “as needed” basis (i.e., if you experience
belt slippage or hesitation).
The second section below describes how to center the belt.
Because each person runs or walks differently, the natural weight
shifts may cause some deflection of the running belt to either the
left or right of center during use. The directions in the second
section tell you how to return the belt to center.
Adjusting the Belt Tension
If the belt feels as though it is “slipping” or hesitating when you
plant your foot during a run, the tension on the running belt may
have to be increased.
To increase the running belt tension:
1. Locate the two large, steel, 3/4-inch hex head bolts at the rear of
the treadmill (see Figure 5-1). These are called belt tension bolts.
2. Place a 3/4-inch open end or socket wrench (or adjustable
wrench) on the left belt tension bolt. Turn the wrench clockwise
1/4 turn to draw the rear roller toward you and increase the belt
tension.
3. Repeat step 2 for the right belt tension bolt. You must be sure to
turn both bolts the same number of turns so that the rear roller
will stay square relative to the frame.
4. Start the running belt and check to see if the “slipping” has been
corrected.
5. Repeat steps 2 and 3 until the slipping is eliminated.
