SAFETY SUMMARY
It is important for everyone involved in the installation and operation of the LiftMaster models SL 1000,
SW 2000, and BG 3000 Master/Slave systems to read the following warnings.
WARNING!
• A vehicle gate is a large, heavy object that is moved by an electric motor. A moving gate can
cause serious injury or death! The safety and well-being of others depends on the installation
of a safe system.
• READ AND FOLLOW ALL INSTRUCTIONS. Improper installation of a gate operator can result
in a dangerous system. SAVE THESE INSTRUCTIONS
• The entrance is for vehicles only. Pedestrians must use separate entrance.
• Gate operators can present serious hazards to persons in the immediate area when not
controlled in a safe manner. Choose one or more controls which together will allow complete
control of the gate. Most importantly, the gate must be able to be stopped at all times in case
of emergency, and the emergency control should be conveniently located, clearly marked, and
visible.
• All controls must be kept out of reach of small children. Serious injury or death can result
from children playing with the controls.
• Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF
THE MOVING GATE.
• All controls should be located so the person operating them can see the full area of gate
movement.
• Use the emergency release only when the gate is not moving.
• KEEP GATES PROPERLY MAINTAINED. Read the Installation and Operation manual. Have a
qualified person make repairs to gate hardware.
• Test the gate operator safety features monthly. The gate MUST reverse on contact with a rigid
object or stop when an object activates the non-contact sensors.
• After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and
retest the gate operator properly can increase the risk of damage, injury or death.
• Gate operators and associated control equipment should be installed by qualified
professional installers who should observe the following safe installation procedures:
1. Power should always be disconnected whenever installing, wiring, or servicing a gate
operator. Moving chains and belts in gate operators can catch clothing or fingers and
cause severe injury.
2. Installation of wiring should comply with all local building and electrical codes.
3. All manual gate locks should be disabled to avoid damage to the gate or gate operator
should the lock become engaged after the operator is installed.
4. All operator controls and safety equipment should be tested at the conclusion of
installation to be sure they are functioning properly.
5. The operation of the gate controls and safety equipment should be reviewed with the
owner and/or end user of the automated gate system. They should also be informed of the
need to maintain control and safety equipment on a regular basis. Safety equipment
should be checked monthly to ensure it is working properly. All installation manuals and
safety information should be left with the owner.
6. Moving gates have pinch points and entrapment zones which can be extremely dangerous
to pedestrians, especially small children.
