and operated in strict accordance with the following safety rules.
Failure to comply with the following instructions may result in serious personal injury or property dam-

Keep garage door balanced.
Sticking or bind-

Do not attempt
to loosen, move or adjust them.
Call for

opener.
To avoid serious personal injury from entangle-
ment,

with your local building and electrical codes.
This is a class 2 double insulated product,

to
avoid damage to garage door.
Any door control buttons (if installed)
MUST be
located where the garage door is visible, but
out of the reach of children. Do not allow
children to operate push button(s) or remote
control(s). Serious personal injury from a

of the opener
.
Activate opener ONLY when the door is in
full view, free of obstructions and opener is
properly adjusted. No one should enter or
leave the garage while the door is in motion.

ley and, if possible,
