Life Fitness Model 4000 Treadmill
How To ... REMOVE AND REPLACE THE DRIVE MOTOR BELT
Tools Required: Phillips screwdriver, socket and ratchet set, hex key wrench set
Step 1
Turn the power OFF at the ON/OFF switch and then unplug the unit from the electrical outlet.
Step 2
Remove the VENT COVER. (See "How To...").
Step 3
Remove the MOTOR COVER. (See "How To...").
Step 4
It will now be necessary to relieve the tension of the STRIDING BELT to allow removal of the DRIVE MOTOR
BELT from the FRONT ROLLER.
HELPFUL HINT: REMOVE THE END CAPS AND MARK THE POSITION OF THE REAR ROLLER ON THE
INSIDE OF THE MOUNTING BRACKET TO LOCATE ITS ORIGINAL PLACEMENT.
THIS WILL HELP WHEN RE-TENSIONING THE STRIDING BELT.
Using a hex key wrench, ALTERNATELY loosen the two TENSIONING SCREWS and WASHERS securing each
side of the REAR ROLLER to the REAR ROLLER MOUNTING BRACKETS an EQUAL number of times counter
clockwise until the STRIDING BELT is slackened enough to allow for partial removal of the FRONT ROLLER.
IMPORTANT: EACH ADJUSTMENT MADE TO ONE SIDE OF THE REAR ROLLER SHOULD BE MET
WITH AN EQUAL ADJUSTMENT TO THE OTHER SIDE OF THE REAR ROLLER TO
MAINTAIN AN IDEAL STRIDING BELT TENSION AT THE CENTER PIVOT POINT OF THE
REAR ROLLER UPON RE-TENSIONING.
