Loosen, do not remove, the 2 screwsthat attach to the left of the bracketthat holds the ends of the belttogether. Slide the bracket off of theend of the belt. DO NOT PULL THEBELT OUT OF THE X-AXIS RAIL ATTHIS TIME.JUST LEAVE ITHANGING. THE PURPOSE IS TORELEASE THE BELT TENSIONCOMPLETELY.
Component Removal and Replacement6. Using a stapler, attach one end of theold belt (2) to one end of the new belt1). Do not overlap the belt and makesure that the teeth are in the samedirection.7. Slowly pull the other end of the oldbelt, allowing the new belt to bepulled through the inside of the X-axisarm. Make sure that you do not twistthe belt going through the rail. Theteeth of the belt should be facing theinside.8. Once the new belt is completely through the X-axis rail, remove the staple anddiscard the old belt.9. Re-attach the belt clamp to the ends of the belt. Make sure that the rounded sideof the clamp faces inwards. Gently pull the belt through the clamp until the slackin the belt is reduced. Leave the belt slightly loose because we will tension thebelt by adjusting the setscrew on the tensioner bracket on the left side of the Xaxis rail. Now, tighten down the screws on the clamp. DO NOT TRIM OFF THEEXCESS BELT AT THIS TIME, WE WILL DO THAT LATER.10. For the next step, you will need a spring scale and a ruler which the end of the ruleris actually the "0" point. Some rulers "0" point is offset from the end so you wouldnot want to use that kind of ruler.
Component Removal and Replacement11. Push the focus carriage all the way tothe left and push the belt clamp allthe way to the right, on the X-axis rail.Place the end of the ruler up againstthe middle of the X-axis arm (NOTinside the belt groove).
