TREADBELT TRACKING, TENSIONING AND MAINTENANCE

DANGER !!

Lethal voltages and moving parts capable of causing serious injury are exposed when the drive housing cover is removed. Under no circumstances should drive housing cover be removed except by a Landice factory authorized technician or under supervision of a Landice technical representative.

TREADBELT TRACKING

The treadbelt is TRACKED by means of two adjustment bolts (9/16" wrench) located at rear of treadmill. By tightening the "close" side and loosing the opposite (same amount) , you can change position of rear roller without changing overall tension. Adjustments should be made with treadmill running, and should be made in 1/4 turn increments. Allow at least 30 seconds for treadbelt to stabilize between each adjustment. Run treadbelt at high speed (6-8 mph).

i.e. If treadbelt is tracking to the right:

a. Turn treadmill on, and bring speed up to 4.0 mph.

b. Using a 9/16" wrench , tighten the right-hand adjustment bolt 1/4" turn. c. Loosen the left-hand adjustment bolt 1/4" turn.

d. Let treadbelt stabilize( rotate for 30 seconds) and readjust if necessary.

TREADBELT TENSIONING

The treadbelt is TENSIONED by the same adjustment bolts used for tracking. To tighten treadbelt, turn both adjustment bolts (clockwise) exactly the same amount. *Failure to turn them equally will effect belt tracking.

Need for tension is indicated by uneven belt speed and may be sensed by sudden stopping of treadbelt when walking or running. Before tightening treadbelt, be certain your drive belt is not loose (see DRIVE BELT TENSION below). DO NOT OVER TIGHTEN TREADBELT / DRIVE BELT!. If you can't reach the palm of your hand under the center of the treadbelt, THE TREADBELT IS TOO TIGHT.

DRIVE BELT TENSIONING

UNPLUG TREADMILL!!!

The drive belt is TENSIONED by a nut (7/16" wrench) located under motor pan which threads to a tensioning hook attached to the drive motor mounting bracket. By turning nut clockwise, you will tighten tensioning hook, pulling down drive motor mounting bracket and tightening drive belt. DO NOT OVER TIGHTEN. If you over tighten this belt you will snap drive motor central shaft. *To gauge tension, twist drive belt between drive motor and front drive roller using your for-finger and thumb. Ideal tension will allow you to twist drive belt 45 degrees, if you can not twist drive belt at least 45 degrees, THE DRIVE BELT IS TOO TIGHT!

WARNING: MOVING PARTS CAN CAUSE SERIOUS DAMAGE. BE SURE TO UNPLUG TREADMILL BEFORE ADJUSTING TREADBELT / DRIVE BELT TENSION !
