COuNTERBALANCE SPRiNG TENSiON MuST BE RELiEVED BEFORE REMOViNG
ANY HARDWARE. A POWERFuL SPRiNG RELEASiNG iTS ENERGY SuDDENLY
CAN CAuSE SEVERE iNjuRY.
Remove the drum wraps from cable drums (if installed) by twisting the drum
wrap while pulling it away from the drum, as shown in
fig. 1.1
.
Check for spring tension by pulling the counterbalance cable on the right
hand cable drum away from the header, as shown in
fig. 1.2
.
STEP 1:
if there is no spring tension the cable will be loose. in addition, the
torque tube should be free to rotate in either direction. if there is no spring
tension, proceed to Step 3. if the counterbalance cable is still taut and the
torque tube is difficult to rotate, that is an indication that spring tension still
exists, proceed to Step 2.
iT iS RECOMMENDED THAT LEATHER GLOVES BE WORN WHiLE uNWiNDiNG

PAWL kNOB MuST BE iN uPPER POSiTiON TO REMOVE SPRiNG
TENSiON, AS SHOWN iN
fig. 1.3
.
Place a ratchet with a 5/8” socket on the winding shaft, as shown in
fig. 1.4
.
nOTE:
A 3” extension is recommended for added clearance from the
horizontal track assembly.
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.
cAUTiOn:
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) at a time.
Release the pawl to allow it to engage with the ratchet wheel. Repeat this
process until all spring tension has been removed from spring.
For Double Springs, repeat the same process for the left hand side. Cables
should be loose and the torque tube should be free to rotate in either
direction.
