Congratulations, you have just purchased one of the world’s safest garage door openers! By 
design, this opener will detect obstructions and reverse rather than force the door through 
obstructions.

 To ensure your new idrive

®

 opener works as intended, your garage door must be 

installed and balanced properly.

If you just fi nished installing a new garage door along with an idrive

®

 opener, then proceed with 

these instructions beginning with Step 14 on page 21. If you were referred to these instructions 
as part of a new door installation, then proceed with these instructions beginning with Step 1 
on page 7.

Before installing the idrive

®

 opener, open and close you door manually to ensure that it 

operates smoothly from top to bottom. A properly balanced door should not take a lot of effort 
to open or close by hand. The door should stay in the open and in the closed position without 
drifting down or creeping up. If a door opens fast going up, the door may need spring tension 
reduced. If the door drops fast going down, the door may need spring tension increased.

If the operation of the door does not meet these criteria, you need to adjust the spring balance 
per your door’s Installation Instructions and Owner’s Manual or call a professional installer to 
make adjustments before installing idrive

®

.

If the door operates properly, check and record your Torquemaster

®

 counterbalance spring 

settings (for Torquemaster Plus spring settings, see warning tag(s) attached to the end 
brackets or  refer to your door Installation Instructions and Owner’s manual). Then proceed 
with unwinding of the spring(s) for installation of your idrive

®

, carefully following the 

instructions in the appropriate STEP R1 of your idrive

®

 Installation Instructions and Owner’s 

Manual. After the idrive

®

 is installed on the Torquemaster

®

 tube, rewind the Torquemaster

®

 or 

Torquemaster

®

 Plus to the previously recorded settings.
