Spring Adjustment (If Required)
(see Diagram 18 on page 11 of Drawings of Installation, Use and Maintenance manual)
NOTE
: The counterbalances system is pre-set at the factory, due to different materials and application a small adjustment may be needed.
WARNING
COUNTERBALANCE SYSTEM AND CABLES ARE UNDER EXTREME TENSION! ALL ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY AN AUTHORIZED, QUALIFIED DOOR SYSTEM SERVICE REPRESENTATIVE. EXTREME CARE NEEDS
TO BE TAKEN DURING THIS PROCESS.
Lift the door and check its balance. Adjust spring, if door lifts by itself and is hard to pull down, or if door is difficult to lift and comes down by itself. A ¼”
square tool (ratchet wrench) (B4 and B5) is required to wind TorqueMaster
®
springs. With the door fully down, clamp mole grips (locking pliers) on
horizontal track just above top roller. To adjust springs, only add or remove 3/10 of a turn (3 teeth of ratchet wheel) maximum at a time. Adjust both sides
equally.
IMPORTANT: On some models, the TorqueMaster
®
is provided with only ONE SPRING, on the right hand side. In this case, the following
operations are needed
to be made only for the right side.
WARNING
BE PREPARED TO HOLD THE FULL TENSION OF THE SPRING
.
ADJU ADDING TENSION:
Insert wrench (B4 and B5) on the outside of the TorqueMaster
®
(1q), ensure tool seats firmly inside, as shown in FIG. 18.1. Gently pull wrench (B4 and
B5) downwards (counter clockwise for the right side, clockwise for the left side) enough to release the pawl (1s), as shown in FIG. 18.3. Pull down
(counter clockwise for the right side, clockwise for the left side) to add tension to the spring. When desired tension is achieved, re-engage the pawl (1r)
by pushing on it with a finger, ensuring it seats properly in between the teeth of the gear (1t) as shown in FIG 18.2, and then, gently release the wrench
(B4 and B5) (clockwise for the right side, counter clockwise for the left side), until pawl is engaged in the gear. Carefully remove the wrench (B4 and B5)
from gear (1q). In case of TorqueMaster
®
with two springs, repeat for opposite side, until desired tension is achieved.
ADJUSTMENT – RELEASING OF TENSION:
Insert wrench (B4 and B5) on the outside of the TorqueMaster
®
(1q), ensure wrench seats firmly inside, as shown in FIG. 18.1. Gently pull wrench (B4
and B5) downwards (counter clockwise for the right side, clockwise for the left side) enough to release the pawl (1s), as shown in FIG. 18.3. Let wrench
rotate clockwise for the right side, counter clockwise for the left side until desired tension is achieved as shown in FIG. 18.3. Re-engage the pawl (1r) by
pushing on it with a finger, ensuring it seats properly in between the teeth of the gear (1t), as shown in FIG. 18.2, and then, gently release the wrench (B4
and B5) clockwise for the right side, counter clockwise for the left side, until pawl is engaged in the gear. Carefully remove the wrench from gear. In case
of TorqueMaster
®
with two springs, repeat for opposite side, until desired tension is achieved.
SERVICE / REPAIR
TorqueMaster
®
springs are designed to provide service life of 10,000 cycles. Springs will need to be replaced in approximately 5 ½ years if you operate
your door 5 times a day.
Door hardware (Hinges, rollers, Counterbalance cables, Track etc.) are designed to provide service life of 40,000 cycles. To obtain a copy of the
counterbalance cable tensile strength documentation, contact your local authorized dealer or manufacturer.
WARNING
DO NOT ATTEMPT TO REPAIR OR SERVICE ANY DAMAGED DOOR YOURSELF. FOR ALL SERVICE
AND REPAIRS, CONTACT AN AUTHORIZED, QUALIFIED DOOR SYSTEM SERVICE
REPRESENTATIVE.
