INSTALLATION
To wind the spring, rotate the winding shaft clockwise,
while watching the mark on the winding shaft (or
socket). Rotate the winding shaft to the required number
of turns for your door or the number recorded during the
Pre-Installation Inspection on page II. Place ratchet pawl
in lower position. Then return to the right hand side and
wind the right hand spring to the required number of
turns or the number recorded during the Pre-Installation
Inspection on page II. Place ratchet pawl in lower
position.
IMPORTANT! DO NOT OVERWIND SPRINGS.
NOTE: Since total turns to balance door can deviate
from spring turn chart values by ± 1/2 turns,
adjustments to the recommended number of spring
turns may be required AFTER rear hangers assembly is
completed.
IMPORTANT! CAUTIOUSLY REMOVE VICE CLAMPS
FROM VERTICAL TRACKS. ADJUSTMENTS TO THE
RECOMMENDED NUMBER OF TURNS MAY BE REQUIRED.
IF DOOR RAISES OFF THE FLOOR UNDER SPRING
TENSION ALONE, THEN REDUCE SPRING TENSION UNTIL
DOOR RESTS ON THE FLOOR. IF THE DOOR IS HARD TO
RAISE OR DRIFTS DOWN ON ITS OWN, THEN ADD
SPRING TENSION. AN UNBALANCED DOOR CAN CAUSE

OPERATION PROBLEMS.
