Safety Requirements

Please read this section carefully. It contains important information concerning the operating features of your Stanley MA900 Door 
Operator, as well as safety precautions to be taken before, during and after installation. 

This caution symbol appears throughout the manual. It identifies important safety instructions. Read these 
instructions carefully. Failure to follow these instructions may result in serious or fatal personal injury or 
property damage.

Information symbol identifies notes that provide important information about the installation and 
operation of the MA900.

Do not wear rings, watches or loose clothing while
installing or servicing the door operator.

Daily safety checks must be made to assure pro-
per door operation. See Safety Checks section of
this manual or the decal on the side of the operator
header.

ANSI Standard A156.19 requires that specific labels
be applied to the door. See Safety Decals section of
this manual for information on applying these labels.

To reduce the risk of electrical shock, connect the
power wire to only a properly grounded outlet.

Never let children operate or play near the door.
Keep RF transmitters in a location inaccessible to
children. Misuse of a door-actuation device may
result in serious injury.

Operate the door only when it is fully visible and
clear of any obstruction. Keep the door in sight until
it is completely closed. KEEP CHILDREN 
AND PETS AWAY FROM THE DOOR WHILE IT 
IS MOVING.

If damage to any mechanical drive or structural com-
ponent of the unit is observed, discontinue use and
contact an authorized Stanley dealer or the Stanley
Customer Service Department. 

If permanent wiring is required by local code, discon-
nect power at the fuse box or circuit breaker box
before attempting wiring connections.

Check local building and electrical codes for manda-
tory installation and wiring requirements.

Read carefully the assembly and mounting sections
of this manual. They provide information about the
tools, and in some cases the additional hardware,
required to ensure a safe and speedy installation.
