22.1 Service Checklist

Preventative servicing of your garage door and opener is just as important as servicing your car. Much like the engine of your car, your garage door is made up of numerous moving parts designed to lift and lower your door safely and efficiently. Ongoing preventative servicing ensures that your door continues to function within factory specifications, greatly reduces the risk of failure and repair bills down the track, and ensures you maintain your Warranty.

? Run the Safety Testing procedures MONTHLY in Section 12 to ensure the garage door is fit for use.

⚠️ WARNING! Failure to maintain your garage door voids the warranty on your garage door opener.

?️ DO NOT DO IT YOURSELF: Door adjustments should only be carried out by experienced persons, as this function can be dangerous if not performed under strict safety procedures.

TECHNICIAN CHECKLIST

1. Lubrication of the critical moving parts including chain drive, tracks, wheels, or cable drum.
2. Tightening of door mounting points along with door bolts, screws, cables, and connectors.
3. Adjustment of spring tension to limit 'spring fatigue'.
4. Adjustment of opener travel limits and force margin to ensure the door opens and closes to specification.
5. Assessment and adjustment of safety components and accessories including safety beams, Auto-Lock, and Safe Lock (if installed).
6. Assessment of the door alignment and the diagnosis of irregular operation remedies.
7. Record Cycle count at each service to establish the next date of service (as per table).

22.2 Battery Replacement

Battery Type: 3V Lithium Battery CR2032.

• To test the battery is working, press and hold a transmitter button. Check the Light Status table to determine if the battery needs replacing.

• Use a screwdriver to remove the screw on the back of the transmitter casing.
• Use the screwdriver to pry open the plastic to expose the circuit board.
• With a non-metallic object (e.g., pen), remove the battery.

Diagram Description: An illustration shows how to use a pen to push the battery down through a side opening to release it from the transmitter.

⚠️ WARNING! Chemical Burn Hazard. Keep batteries away from children.

22.3 Battery Disposal

When batteries reach the end of their usual life, in accordance with the Australian Battery Recycling Initiative, please follow the next simple steps for protecting the environment. Refer to the Automatic Technology website for information on where to recycle batteries in Australia.

⚠️ WARNING! The Battery shall be disposed of properly, including keeping them away from children. Even used batteries may cause injury.

DO NOT throw the batteries in municipal waste. This symbol ? of the crossed out wheeled bin indicates that the battery should not be placed in the municipal waste. Check your local regulations for appropriate disposal of the batteries.

Recycling all batteries will have other environmental and social benefits:

• Some batteries are less toxic but hazardous for other reasons. Lithium batteries can explode or catch fire in landfill, while button cells are dangerous if swallowed by children. Recycling offers a safe and environmentally responsible solution for end-of-life batteries.
• Battery recycling recovers non-renewable materials such as lead, cadmium, stella, zinc, manganese, cobalt, silver, plastics, and rare earth elements.
• Removal of batteries and other hazardous household products from household waste facilitates the recovery of organic materials through alternative waste technologies such as composting. Batteries and heavy metals are known contaminants in compost.
• The community supports recycling because it reduces waste to landfill and achieves environmental benefits.

⚠️ WARNING! Prior to disposal, recycling, or collection, all battery terminals must be securely insulated with a non-conductive material to prevent any two batteries from short-circuiting and generating heat during storage or transport. Battery terminals may be insulated with electrical tape; or batteries may be individually packaged in a non-conductive material (e.g., plastic bag or original packaging).

22.4 Warranty

Warranty is conditional on proper servicing as listed in 22.1 Service Checklist. Full details of the warranty are available in your Owners Opener Handbook, from your nearest ATA office, or visit the ATA Website ata-aust.com.au.
