Spring Tension Removal
Counterbalance spring tension must be
relieved before removing any hardware.
A POWERFUL SPRING RELEASING ITS
ENERGY SUDDENLY CAN CAUSE SEVERE
INJURY.
Starting with the right hand side, ensure
pawl knob is in upper position. Place a
ratchet with a 5/8” socket on the winding
shaft.
NOTE:
A 3” extension is also recommended
for added clearance from the horizontal
angle.
To remove spring tension, ensure the ratchet
and socket is set so that it will add tension
(counter clockwise) on the right hand side
and (clockwise) on the left hand side. Rotate
ratchet to relieve pressure between the pawl
and the ratchet wheel. Push in on the pawl
to allow the ratchet wheel teeth to pass by.
NOTE:
In the event of a broken spring, it
might not be necessary to unwind spring(s).
IMPORTANT!
BE PREPARED TO HOLD THE
FULL TENSION OF THE SPRING.
Gently let the ratchet rotate upward, while
watching the number of teeth on the ratchet
wheel pass by the pawl. Remove 3/10 of a
turn (watch the 3 teeth of the ratchet wheel
pass the pawl). Release the pawl to allow it
to engage with the ratchet wheel. Repeat
this process until all spring tension has been
removed from spring(s). Cables should be
loose and the torque tube should be free to
rotate in either direction.
IMPORTANT!
SPRING(S) ARE FULLY
UNWOUND WHEN COUNTERBALANCE
CABLES HAVE NO TENSION.
IMPORTANT!
DO NOT USE AN IMPACT GUN
TO UNWIND THE SPRINGS.
Tools Needed:
Ratchet Wrench
5/8” Socket
3” Extension
Gloves
Step Ladder
