4. On L7 models check that end cap is not mis-aligned. Re-align end caps so they are flush
with side frame covers. If that doesn't solve problem replace rear roller bolts.
5. Is belt rubbing on cross brace underneath treadmill? Sometimes these get bent during shipping.
Bend back so belt will not rub.
6. Is there excess wax build up on deck, belt, and rear roller? Remove belt and wipe down deck
and rear rollers.
7. Is there excess Slip Cote? If you see Slip Cote oozing from sides of belt or off end of deck
remove belt and wipe down deck, belt, and rollers.
8. Is it a commercial treadmill? Landice uses a stiffer belt on Club models to increase treadbelt
life. These stiffer belts make more noise and are considered normal.
9. On older machines check that the treadbelt and deck are not worn excessively and making
noise. We recommend the replacement of both deck and belt if either is worn.
10. Does noise occur when seam passes over roller? A slight amount of noise is normal. If it is
excessive check the seam for damage or for wax buildup on roller.
11. If noise occurs when walking, check that customer is not walking too far to the rear causing
the belt to drag over the rear of the deck.
12. Noises can travel. Make sure noises are not coming from rollers, drive belt, drive motor, rear
roller touching frame, mis-aligned end caps, or deck. Use automotive stethoscope and or
process of elimination to be sure where noise is coming from.
13. Check that Drive roller is parallel to Take Up roller. If its not, the belt will be tensioned
unevenly. Some adjustment is possible on front roller (try side opposite motor and pulley first)
and should be enough to bring Drive and Take Up roller into correct alignment.
14. Check that frame is square. Sometimes mills can be jarred out of square and this can
causetracking and noise problems. Check frame corners with square.
Note: Always make sure you have a new deck surface when replacing treadbelt. Also if deck
appears higher than usual so that it seems to be rubbing against frame, try installing additional felt
washers between the frame and rear of the deck.
Special Note: Most Treadmills built between July of 2001 and January 2002 had a "floating"
Take up roller design in which the roller would rest solely on the tension bolts.
Occasionally if a customer stepped on the rear roller as they got off the machine they would
bend the roller down. This caused a variety of problems including sheared holes in the bed
end caps, and treadbelt rubbing noises because of the belt being bent down and catching
the safety brackets on the back of the deck as it rolls. The solution to this problem was a
new Take up roller with a "wing tipped" shaft that rested against the inside of the treadmill
frame. This way there is no play and customer cannot bend the take-up roller down
anymore.
