Note: Windows will cause the top section to be significantly heavier than the remaining sections.
Remove any vice clamps. Lift the door and check its balance. Adjust spring(s) if door lifts by itself (hard to pull down) or if door is difficult to lift (easy to pull down). Anytime spring adjust- ments are made, ratchet pawl knob must be in the upper position. An unbalanced door can cause idrive® or TorqueMaster® Plus operation problems.
Close the door and place vice clamps onto both vertical tracks just above the third track roller. This is to prevent the garage door from rising while adjusting the counterbalance spring(s).
IMPORTANT: To adjust springs, only add or remove a maximum of 3/10 of a turn (three teeth on the ratchet wheel) at a time. Both sides need to be adjusted equally on double spring doors.
Add spring tension: The ratchet wheel is made of 10 teeth. To add spring tension, ensure the ratchet and socket is set so that it will tighten counter clockwise on the right hand side and clockwise on the left hand side. Place the ratchet wrench with 5/8” socket and 3” socket extension onto the winding shaft, pull down to add 3/10 of a turn. Watch as three teeth of the ratchet wheel pass over the pawl, creating three “clicks”.
Remove spring tension: To remove spring tension, place a regular 5/8” wrench onto the winding shaft. Pull down on the wrench to relieve pressure between the pawl and the ratchet wheel. Push in on the pawl to allow the three ratchet wheel teeth to pass by the pawl, as you carefully allow the wrench to be rotated upward by the spring tension, release the pawl to allow it to engage with the ratchet wheel.
Important: Be prepared to hold the full tension of the spring.
Important: Do not add or remove more than 1 spring turns (1 spring turn equals 10 teeth on ratchet wheel) from the recommended number of turns shown on the winding spring turn chart.
If the door still does not operate easily, lower the door into the closed position, unwind spring(s) completely, and recheck the following items:
1.) Check the door for level.
2.) Check the TorqueMaster® spring tube and flag angles for level and plumb.
3.) Check the distance between the flag angles, which must be door width plus
4.) Check the counterbalance lift cables for equal tension, adjust if necessary.
5.) Rewind the spring(s).
6.) Make sure door isn’t rubbing on jambs.
Note: If an idrive® opener was installed and you have completed this step, refer to the idrive® Installation Instructions and Owner’s Manual to complete your idrive® installation.
