Outer Covering
Removal:
Disconnect the treadmill from the mains and remove the two (2) large screws in the
outer covering using a cross-recess screwdriver. The covers can then be lifted up from
the frame of the treadmill.
Replacement:
Position the two outer coverings on both sides of the frame. Then tighten the large
screws. It is important to check whether the treadmill scrapes on the covering panels by
moving the surface backwards and forwards. If this is in fact the case, the screws must
be loosened again and the covers moved away from the surface.
Drive Motor and Pulley
The instructions are supplied with the new or replacement motor, pulley is included.
Drive Belt
Required tools:
2 ring fork wrenches 17, 17 / 10 socket nut, ratchet
Removal:
1. Mark the position of the right-hand bearing support. This bearing holds the front
shaft on the frame. Then measure the distance between the upper and lower part
of the treadmill belt (in the middle). This measurement is made exactly between
the inner edges of the belt teeth and the value is kept for future reference.
2. Unscrew the two screws of the bearing support, but DO NOT REMOVE.
3. Take the drive belt off the drive motor.
4. Remove the outer bearing screw and pull the drive belt out from under the
bearing support.
5. Replace the outer bearing screw and nut. The nut must sit firmly on the screw.
6. Remove the inner bearing screw and pull the drive belt out from under the
bearing support (alternatively, cut the old belt). Place the new drive belt under the
bearing support (with the teeth UPWARDS).
Replacement:
1. Install the inner bearing block. Remove the outer bearing block and pull the drive
belt out from the under the block. Then position the drive belt in the pulley on the
front shaft, checking that the teeth engage correctly. Then replace the screw and
all other parts.
2. Pull the front shaft using a rod or C clamp to pull the running belt tight. Measure
the clearance between the running surfaces and adjust the value noted above.
This should be approx. 20.5 cm (optimum running).
3. Screw the bearing block screws to approx. 50 foot pounds.
4. Check that the drive belt runs correctly in both pulleys and can be moved easily
in the middle by a width of 1 - 2 fingers.
