PREPARATION
Correct all “High Risk”
areas on the garage door
before installation of the new Martin Torsion Drive
Opener. If unable to correct, replace garage door with
a new Martin Garage Door. See Back Page
Decide if the Motor Assembly
will be mounted to the
right side or left side of the garage door.
The Torsion Tube/Shaft
protrudes 5”(130) beyond the
lock-on/side bearing bracket. (Motor Assembly side
clearance requires an extra 4.5”(114) beyond the end
of the tube/shaft.) See Figure 12, 13
A qualified electrician
should install a grounded
electrical outlet within 5’(1520) of the Control Box
Assembly location according to local codes.
See Figure 1
Make sure
the garage door is properly balanced, the
moving steel parts properly lubricated, and the jambs
waxed where the garage door rubs. The door should
work free and easy as it opens and closes. Please call
a trained Martin Dealer if you have a problem or do not
understand.
The garage door
should be at least 5’(1520) high.
