The Makita BO003CG 40V XGT 125mm Brushless Random Orbit Sander is a lightweight and versatile disc...The Makita BO003CG 40V XGT 125mm Brushless Random Orbit Sander is a lightweight and versatile disc sander with an external battery connection. Unlike other similar style sanders, the BO003G’s battery unit is at the end of an adapter unit that can be clipped to your belt. By doing so, it massively reduces the size and weight of the sander which results in better manoeuvrability and control. From the top of sander to the sanding pad, it is only 96mm in height ensuring that as a compact tool, you are give the freedom to easily move it around your work surface. The sander produces a 3.0mm eccentric diameter while the speed of the sander won’t lessen, even under load thereby providing consistent performance. Supplied with a pad saver, this prevents clogging of the sander resulting in continuous operation. Thanks to the inclusion of the brushless motor, the BO003G delivers 6000-10,000 rpm no load speed with a 3.0mm eccentric action. Dust is collected neatly into the supplied dust bag, although an external dust extractor can be connected for efficient extraction. Auto-Start Wireless System (AWS) allows the connection to a compatible dust extractor for automatic start-up and shut down via Bluetooth. This saves time and power – using only what is required. At the heart of this Sander is the brushless motor that allows you to use the tool efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it. The Makita BO003CGZ 40V Brushless Random Orbital Sander 125mm Body Only is supplied as the machine only without the batteries. It runs off the Makita 40v batteries. Model BO003CG is a battery powered random orbit sander powered by a 40Vmax XGT Li-Ion battery. Excellent maneuverability has been achieved by using a connector-style connection to the battery, reducing the load on hand and further keeping the overall height low. The main features and benefits are: A connector connection to the battery, Net type abrasive discs, Pad saver discs, Compatible with AWS (Auto-start Wireless System). Brushless maintenance-free and long-life motor Runs off the 40v batteries. 125mm sanding pad diameter. Dimensions 233 x 123 x 96 mm. Compatible with the connector style connector to the battery Built in dust extraction system Anti-restart Hook and loop fastening Features a new abrasive type disc; net type Self-dust collection Auto-start wireless system (AWS); Chip 198900-7 required (sold separately) 125mm abrasive disc paper.

Product Information
Full details
The Makita BO003CGZ is designed for professional woodworkers and serious DIY enthusiasts who need a lightweight and highly maneuverable sander for detailed finishing work. Its key benefit is significantly reduced user fatigue due to the external battery connection, allowing for prolonged use. A potential caveat is that it is sold body-only, requiring separate purchase of 40V XGT batteries and a charger. This 125mm brushless random orbit sander offers consistent performance with a 3.0mm eccentric action, integrated dust collection, and compatibility with Makita's Auto-Start Wireless System (AWS).

FAQs
What is the main advantage of the external battery design?
The main advantage is significantly reduced weight and bulk on the tool itself. The battery is connected via a cable and can be clipped to your belt, leading to less user fatigue and improved maneuverability, especially during extended use or overhead work.
Does this sander come with batteries?
No, the Makita BO003CGZ is sold as 'body only'. You will need to purchase Makita 40V XGT Li-Ion batteries and a compatible charger separately.
What is the eccentric diameter and why is it important?
The eccentric diameter is 3.0mm. This refers to the orbit of the sanding pad. A smaller orbit like 3.0mm is ideal for fine finishing and removing less material, reducing the risk of sanding through veneer or creating deep scratches.
How does the Auto-Start Wireless System (AWS) work?
AWS uses Bluetooth to wirelessly connect the sander to a compatible dust extractor. When you start the sander, the dust extractor automatically turns on, and it shuts off shortly after the sander is turned off. This requires a separate AWS chip for the sander and a compatible dust extractor.
Can I use regular sanding discs with this sander?
Yes, it uses standard 125mm hook and loop sanding discs. However, net type abrasive discs are recommended as they are designed for optimal dust extraction when used with the sander's dust collection system or an external extractor.
What is the height of the sander?
The height from the top of the sander to the sanding pad is approximately 96mm, making it a very compact tool that allows for easy handling and access to tight areas.
Is the brushless motor better than a brushed motor?
Yes, brushless motors are generally more efficient, require less maintenance, run cooler, and have a longer lifespan compared to traditional brushed motors. They also allow for more precise power delivery.
Troubleshooting
Sander does not start
Ensure the 40V XGT battery is fully charged and properly seated in the adapter. Check that the battery cable is securely connected to the sander. Verify the battery is compatible (40V XGT).
Reduced sanding power or speed
Check battery charge level. Inspect the sanding pad and disc for excessive clogging or wear. Ensure there are no blockages in the dust extraction system. The brushless motor should maintain speed under load, so significant drops may indicate a battery or blockage issue.
Excessive vibration or noise
Ensure the abrasive disc is correctly and securely attached. Check the pad saver and backing pad for damage or excessive wear. If the issue persists, the tool may require professional servicing.
Dust collection is ineffective
Empty the dust bag frequently. Ensure the dust port and any connected external extractor hoses are clear of debris. Check that the pad saver is properly fitted and not damaged, as this can affect airflow.
AWS not connecting
Confirm both the sander and the dust extractor have compatible AWS chips installed and are powered on. Ensure Bluetooth is enabled on both devices. Check that the distance between the sander and dust extractor is within the effective Bluetooth range (typically around 10 meters).
