Walking Belt Tension Check; Walking Belt Alignment - Bodyguard T-30 User Manual

If you wish to adjust the pulley alignment, depending on the model and components used, there are 3
parts that could possibly be adjusted if drive belt realignment is required.
1. If your drive motor has setscrews securing the drive motor pulley to the drive motor
shaft then it is possible to loosen them and shift the drive motor pulley laterally on the drive
motor shaft to the desired position. Secure the setscrews tightly to avoid the pulley squeaking
on the drive motor shaft.
2. The front roller may have some small lateral movement, which could be enough to help with
alignment. Loosen the left vertical front roller securing bolt and the right front roller angle
adjustment bolt and nut until the front roller has some play.
screwdriver, pry the front roller against the frame to shift it left or right, it will not move much
but you may get just the adjustment you need. Secure the bolts tightly in the new position. If
you wish to adjust the front roller pulley angle, it may be adjusted using the right front roller
angle adjustment bolt. However, if making and adjustment to this bolt be sure to adjust the
rear roller angle accordingly so they are parallel or the walking belt will not stay centered.
3. The drive motor support plate is designed to move along a groove forwards and backwards
but if loosened it may be possible to adjust it laterally a small amount before retightening it.

WALKING BELT TENSION CHECK

The walking belt wraps around the front and rear rollers as well as the deck.
It is important that the walking belt tension is set correctly to avoid premature wearing of parts and to
maintain user comfort and safety.
An over tightened walking belt can cause roller bearing damage and result in higher than usual
amperage draw. Roller bearings are very durable and rarely wear out so a treadmill with both front
and rear roller damage is usually the result of an over-tightened walking belt.
A loose walking belt can slip on the rollers when the user's foot strikes down, causing the walking belt
to jerk, which is a serious safety hazard for the user and can result in a fall.
The walking belt tension can be adjusted by increasing or decreasing the distance between the front
and rear rollers via the rear roller adjustment screws. Turning both the left and right rear roller
screws clockwise will increase the distance between the front and rear rollers and therefore increase
the walking belt tension. Turning them anti-clockwise will decrease the distance between the front
and rear rollers and reduce walking belt tension. The correct walking belt tension should allow the
walking belt to be lifted in the middle of the deck length about 5 inches. However, it is important to
test the belt tension manually by walking, jogging and then running on the unit and confirming that
the walking belt does not slip on the rollers. Always be sure that the rear roller is parallel with the
front roller after making any adjustments or the walking belt will drift to one side. If this occurs a
walking belt alignment will be required (see section 7.5)

WALKING BELT ALIGNMENT

WARNING – Do not stand on the belt during this procedure. Keep loose clothing and long hair away
from the belt and rollers when performing a belt alignment.
Note: Each time a treadmill is moved, a walking belt alignment should be completed. An uneven floor
or incorrectly adjusted rear levelers usually results in the walking belt not staying centered.
The walking belt should be evenly centered along the full length of the foot rails at all times. If the
walking belt drifts too far to one side it will make contact with the foot rail on the right or the front left
roller pulley and the foot rail on the left. This will cause damage to the edge of the walking belt
resulting in fraying. Bodyguard treadmills use crowned rollers that are contoured to help keep the
belt centered, however, if the front and rear rollers are not parallel then the walking belt will drift
during operation. The front and rear rollers are adjusted at the factory to be parallel but often the rear
