MA4X-707X and MA4X-715X Series Installation
Caution: Do not drill additional holes in the actuator body. Six pre-drilled holes are located
on each side, under the label, to accept #10-24 thread-forming screws for mounting
accessories.
Note: The MA40-707X and MA40-715X series actuators come equipped with standard
universal mounting clamp installed. For damper shafts larger than 3/4" (19 mm) in
diameter, the AM-687 universal mounting clamp is required (order separately). The AM-687
clamp accommodates round shaft sizes up to 1.05" (27 mm) in diameter or 5/8" (16 mm)
square shafts.

• If the universal clamp is not set to 0
° on the position indicator, manually wind the
actuator in the direction indicated with hex wrench from -5
° to 0° and lock with a
screwdriver.
• When operating manual override, back off 5
° from full open mechanical stop to ensure
proper release.
• Do not attempt to use the manual override with actuators mounted in tandem. Damage
to the gear train could occur.
• Using power tools to adjust the manual override will cause damage to the gears.
• To unlock manual override without power, crank the manual override in the direction
