BALANCING DOOR
CAUTION
WINDOWS MAY CAUSE THE TOP SECTION TO BE SIGNIFICANTLY HEAVIER
THAN THE REMAINING SECTIONS. TO PREVENT ANY SUDDEN DOOR ACCEL-
ERATION BETWEEN THE TOP AND BOTTOM, MOTOR OPERATE ALL DOORS
WITH WINDOWS.
See Figure 49 for the following steps.
23a. Remove any locking pliers. 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 (drifts
down). Anytime spring adjustments are made, the pawl knob must be in the
upper position . An unbalanced door can cause TorqueMaster
1
problems.
23b. Close the door and place locking pliers onto both vertical tracks just above
the third track roller. This is to prevent the garage door from rising while adjusting
the spring(s).
IMPORTANT: To adjust springs, only add or remove a maximum of 3/10 of a turn
(three teeth on the ratchet wheel
equally on double spring doors.
WARNING
1
EXTREME CAUTION SHOULD BE USED WHEN WINDING SPRINGS AS
FAILURE TO FOLLOW THE INSTRUCTIONS OR USE THE PROPER TOOLS CAN
LEAD TO DEATH OR SERIOUS INJURY TO PERSONS OR PROPERTY. BEFORE
ATTEMPTING TO WIND THE SPRING, MAKE SURE YOU HAVE READ AND
UNDERSTAND THE INSTRUCTIONS. IF YOU ARE UNCLEAR ON ANY ASPECT
OF THE INSTALLATION PROCEDURES, YOU SHOULD CONSULT A TRAINED
DOOR SYSTEMS TECHNICIAN.
23c. Adding Spring Tension: The ratchet wheel
spring tension, tighten counter clockwise on the right hand side and clockwise on
the left hand side. Place pawl knob in upper position
with 5/8" socket
6 5
add 3/10 of a turn. Watch as three teeth of the ratchet wheel pass over the pawl
, creating three "clicks." Place pawl knob in lower position
3
spring applications, repeat the same process for the other side.
WARNING
WHEN WINDING THE SPRING BE PREPARED TO HOLD THE FULL TENSION
OF THE SPRING. FAILURE TO SECURELY HOLD THE RACHET WRENCH CAN
RESULT IN SERIOUS INJURY.
23d. Removing Spring Tension: To remove spring tension, place a regular 5/8"
wrench onto the winding shaft
down on the wrench to relieve pressure between the pawl
wheel . Push in on the pawl

by the pawl , as you carefully allow the wrench to be rotated upward by the
3
spring tension, release the pawl 3 to allow it to engage with the ratchet wheel
. Place pawl knob in lower position
same process for the other side, except clockwise.
IMPORTANT: Do not add or remove more than 1 spring turn (1 spring turn
equals 10 teeth on ratchet wheel) from the recommended number of turns
shown on the winding spring turn chart. If necessary, consult a trained door
systems technician to obtain replacement springs.
23e. If the door still does not operate easily, lower the door into the closed position,
unwind spring(s) completely, and recheck the following items:
23f. Is the door level?
23g. Are the TorqueMaster
23h. Does the distance between the flag angles equal door width plus 3-3/8" to
3-1/2" (86 mm – 89 mm)?
23i. Do the counterbalance lift cables have equal tension? Adjust if necessary.
