BONDTECH INDX BELT HELPER TOOL

The Demon INDX Belt Helper Tool allows you to keep both hands on the job without loosing track of your belts.

• It lets you lock the belts in the correct position relative to each other - so they'll always be the same length next to each other!

• It lets you fine tune the belt position with x4 adjustment bolts!

• It lets you cut the belts all the way back to inside the mounting plate without any need to handle the loose ends!

• It lets you make maintenance crazy easy

• It lets you remove & replace your belts to the exact same place & tension they were when you took them off!

...Plus probably some other stuff I haven't written down too! haha

HOW TO USE

• Set the arm adjustment at about 50% - so you can move both inwards & out.

• Slide your belts into the clamps on each side of the tool.

• Align them with the slots in the arms & on the INDX mounting plate

• Tighten down the clamps to hold the belts in place

• The belts if new should be set to the same position & be of the same length

• Install the mounting plate to the MGN12 bearing carriage - LOOSELY 

• Make sure the belts are still good, make any adjustments to the arms you need

• Tighten down all mounting bolts & remove the tool - Job done!

To remove belts from a printer

• Add the tool to the installed setup & make sure arms are set equally

• Tighten the clamp bolts on the arms to hold the belts

• Remove the bolts holding the mounting plate on the MGN12 bearing 

The belts will remain in the correct positions as you removed them for the duration of your maintenance work
