Stamina Products T3000 45-1003 - Manual (Page 11)

The basic idea behind the manual treadmill is to have the belt running on a treadmill board and between two
rollers so that the belt will move without much effort. In order for the belt to run smoothly, there are a few
points that need to be noted.
TREADMILL ADJUSTMENTS
BELT ALIGNMENT
The belt must be in the center of the treadmill to prevent it from rubbing against the flywheels. If the belt rubs
a flywheel, it will be difficult to keep the belt moving and eventually damage the edge of the belt.
The treadmill has belt guides welded to the bottom of the treadmill frame that move the belt toward the
center of the treadmill. However, the rear roller must be properly aligned with the treadmill frame and front
roller if the belt is to remain centered on the treadmill.
The bolts in the rear of the treadmill (one on the left and the other on the right) adjust the alignment of the
rear roller as well as the tension of the belt.
The belt will run to the side of the loose rear bolt.
Hint:
BELT DRIFTING LEFT
Turn the left screw 1/4 turn CLOCKWISE and the right screw 1/4 turn
COUNTER-CLOCKWISE, then walk on the treadmill. Repeat if needed.
BELT DRIFTING RIGHT
Turn the left screw 1/4 turn COUNTER-CLOCKWISE and the right screw
1/4 turn CLOCKWISE, then walk on the treadmill. Repeat if needed.
NOTE:
When you believe the WALKING BELT is centered, use the treadmill for three (3) minutes to verify the
WALKING BELT won't drift to one side. If the WALKING BELT continues to drift, the floor may not be level.
Rotate the treadmill 90 degrees or move the treadmill to another location.
BELT TENSION
The belt should be tight and not lying on the treadmill board. If the belt is too loose, the belt will slip on the
front roller and you will notice a jerky movement when you walk on the treadmill. If the belt is too tight, the
edges of the belt will begin to curl and more effort will be required to move the belt. Excessive belt tension
can also damage the bearings in the rollers. The bolts in the rear of the treadmill (one on the left and the
other on the right) adjust the tension of the belt as well as the alignment of the rear roller.
BELT TOO LOOSE: Use the 4mm ALLEN WRENCH to tighten the bolts in the rear of the treadmill.
Tighten both rollers 1/4 turn at a time until the belt stops slipping on the front roller.
BELT TOO TIGHT: Use the 4mm ALLEN WRENCH to loosen the bolts in the rear of the treadmill. Loosen
both rollers 1/2 turn at a time until the belt begins to slip on the front roller. Then use the procedure above to
tighten the belt.

Eyeball the rear roller to make sure both the right side and the left side of the roller are the same
distance from the back edge of the treadmill. Use the 4mm ALLEN WRENCH to make these
adjustments. Turn the bolts Clockwise to tighten and Counter-Clockwise to loosen.
