WARNING
WARNING: THE OPERATOR ASSEMBLY IS HEAVY AND CAN CAUSE SERIOUS INJURY OR DEATH SHOULD IT BE
DROPPED DURING INSTALLATION. TAKE ALL NECESSARY SAFETY PRECAUTIONS TO AVOID DROPPING THE
OPERATOR (I.E. TETHER/TIE DOWN) PRIOR TO ATTEMPTING INSTALLATION. SCAFFOLDING OR SCISSOR-LIFTS/
PLATFORM-LIFTS ARE ADVISED FOR OPERATOR INSTALLATION. NEVER ATTEMPT TO INSTALL AN OPERATOR
ABOVE EYE-LEVEL OR FROM A LADDER.
Operator Installation
ENSURE THAT PREVIOUS STEPS FOR SHAFT COLLAR/BENT KEY INSTALLATION HAVE BEEN PROPERLY
FOLLOWED BEFORE PROCEEDING.
Align the keyway of the gearbox with the pre-
mounted bent key (see Key Shaft Collar/Key
Installation on previous page) located on the
mounting side of the shaft. Bent section of key
should face the shaft collar as noted in previous
instructions.
Adjust the keyway of the hollow gearbox so that
it is facing upwards (use a 3/8" ratchet placed
in the bottom entry of the operator to move to
rotate the hollow gearbox). Slide the gearbox
onto the shaft until it makes contact with the
bend of the key.
Fasten the torque arm to structural support by
means of the supplied bolt, locking nut and
washers. The supplied bracket may be required.
If the torque arm does not align with structural
support, you may try adjusting the torque
arm position on the gearbox (see Assembling
Torque Arm to Gearbox) accordingly or use the
Torque Arm Bracket.
If the Torque Arm Bracket is needed, pre-
assemble the bracket to the Torque arm using
the provided fasteners prior to sliding on the operator (NOTE: DO NOT TIGHTEN THE NUT FULLY). Locate the
proper position for the bracket on solid structural support (i.e. wall), mark the mounting holes, and install
anchors as required (you may need to remove the operator to do this). Fasten the bracket to the support,
then tighten the Torque Arm Bolt.
FAILURE TO SECURELY FASTEN TORQUE ARM COULD RESULT IN DAMAGE, SERIOUS INJURIES OR
DEATH AND WILL VOID THE WARRANTY.
