NOTE: If you have a Torquemaster
®
counterbalance,
skip this step and continue with Step 12 on page 20.
NOTE: It is recommended that leather gloves be
worn while winding the TorqueMaster
®
Plus springs.
FAILURE TO WEAR GLOVES MAY CAUSE INJURY TO
HANDS.
See chart on page 19 for proper spring tension setting.
Double check to ensure the counterbalance cable is
aligned in the first and second groove of the cable
drum, as shown in Step 10.
There are two methods for counting the spring turns as
you wind. One method is to identify the black tooth on
the ratchet wheel inside of the end bracket. When the
wheel makes one revolution and the tooth returns to its
starting point, one turn has been made. The other
method is to make a mark on the winding shaft (or
socket) and end bracket, and count your turns in this
manor.
IMPORTANT! PAWL KNOB MUST BE IN UPPER
POSITION TO ADD/ REMOVE SPRING TURNS. AFTER
ADDING / REMOVING SPRING TURNS, PAWL KNOB
MUST BE PLACED BACK IN LOWER POSITION.
Beginning with the right side, place a mark on winding
shaft (or socket) and end bracket. Turn pawl knob on
the end bracket to the upper position. Using a ratchet
with a 5/8” socket,wind the spring by rotating the
winding shaft counter clockwise, while watching the
mark on the winding shaft.
NOTE: A 3” extension is also recommended for added
clearance from the horizontal angle.
After 2-3 turns, remove the ratchet and adjust the cable
on the left side. Ensure the cable is in the first and
second groove of the cable drums as shown in Step 10
and clear of any obstructions.
NOTE: Single spring applications require no spring
winding on left hand side, but need cable tension
adjusted.
IMPORTANT! ENSURE COUNTERBALANCE CABLE
TENSION IS EQUAL FOR BOTH SIDES PRIOR TO FULLY
WINDING SPRING(S) TO APPROPRIATE NUMBER OF
TURNS. IF CABLE TENSION IS UNEQUAL, REFER TO
STEP 10.
See the Spring Turn chart.
For SINGLE SPRING applications, return to the right
hand side and continue winding the spring to the
required number of turns for your door or the number
record during the Pre-Installation Inspection on page II.
Place pawl knob in lower position.
For DOUBLE SPRING applications, place a mark on the
left hand winding shaft and end bracket. Place the
ratchet with 5/8” socket onto the left hand winding
shaft end.
