NOTE: If you have a Torquemaster
®
counterbalance, skip this step and continue
with Step 2 on page 10. If you have a
Torquemaster
®
Plus counterbalance system,
complete Steps 2-3 on pages 8 and 9.
IMPORTANT! RIGHT AND LEFT HAND IS
ALWAYS DETERMINED FROM INSIDE THE
GARAGE LOOKING OUT.
Shake the TorqueMaster
®
spring tube
assembly gently to extend the winding shafts
out about 5" on each side. For single spring
applications, there will be no left hand spring
in the TorqueMaster
®
spring tube assembly.
Lift the TorqueMaster
®
spring tube assembly
and rest it on the top of the flagangles.
NOTE: Cable drums are marked right and
left hand. Cable drums and TorqueMaster
®
spring tube assembly are cam shaped to fit
together only one way.
Pre-wrap the Torquemaster
®
Plus cable
drum with the counter balance cable 1-1/2
wraps (see illustrations).
To install the cable drum, slide the correct
cable drum over the winding shaft until the
cable drum seats against the TorqueMaster
®
spring tube assembly.
The winding shaft must extend past the
cable drum far enough to expose the splines
and the groove. Align the winding shaft
groove with the round notch in the flagangle.
For double spring applications, repeat for
opposite side.
For single spring applications, pre-wrap the
left hand Torquemaster
®
Plus cable drum
with counter balance cable 1-1/2 wraps and
insert the loose winding shaft into the cable
drum prior to sliding the cable drum over the
TorqueMaster
®
spring tube assembly.
NOTE: On single spring applications, take
care in handling the loose winding shaft (left
side) so that it does not slide back into the
TorqueMaster
®
spring tube assembly.
