The Makita GRH10D1W is a top - notch cordless solution for heavy - load concrete applications. Powered by a 40V max XGT® battery and a Makita - built brushless motor, it offers up to 40% more hitting force than some models, giving you the power and performance you need. The variable speed dial and trigger let you adjust the speed according to the job at hand.Equipped with Active Feedback - Sensing Technology (AFT®), the motor shuts off electronically if the bit rotation suddenly stops, protecting you and the tool. Anti - Vibration Technology (AVT®) goes beyond just a padded handle. It uses an internal counterbalance with air pressure to move counterweight pistons against the drive piston, effectively reducing vibration. The vibration - absorbing back and side handles further enhance comfort. Extreme Protection Technology (XPT™) makes the tool more resistant to dust and water, perfect for tough job sites.The GRH10D1W comes with dust extraction capabilities and is OSHA Table 1 compliant. You can choose between an on - board HEPA Dust Extractor or a stand - alone AWS® Extractor. The Auto - Start Wireless System (AWS®) uses Bluetooth® to communicate between the tool and the dust extractor. This means the extractor automatically powers on and off with the tool, boosting productivity on a single charge and reducing noise at the work site.Constant speed control adds extra power under load for optimal performance. The torque - limiting clutch prevents gear damage by disengaging gears when the bit binds. An electric brake allows for quick repositioning, and the built - in L.E.D. light and ergonomic soft - grip handle with a large 2 - finger trigger provide added convenience. It has three operation modes: Rotation Only, Hammering with Rotation, and Hammering Only, suitable for a wide range of trades. It accepts SDS - PLUS bits and can use Makita's extensive line of Rotary Hammer Carbide bits. The XGT system, which uses 40V max lithium - ion batteries, is engineered for high - demand applications, enabling a cordless job site transition.Included in the kit are a 40V max XGT® Brushless Rotary Hammer, a 2.5Ah Battery, a Rapid Optimum Charger, a Dust Extractor Attachment, a Side Handle Assembly, grease, a cloth towel, and a tool bag.
Using the Makita GRH10D1W is straightforward. First, charge the 40V max XGT® 2.5Ah battery using the provided Rapid Optimum Charger. Once charged, insert the battery into the tool. You can then select the appropriate operation mode (Rotation Only, Hammering with Rotation, or Hammering Only) according to your task. Use the variable speed dial and trigger to adjust the speed. When using the dust extraction feature, if you have an AWS® - capable dust extractor, connect it wirelessly via Bluetooth®. The extractor will start and stop automatically with the tool. As for safety, always wear appropriate personal protective equipment like safety goggles and gloves. If the bit suddenly stops rotating, the AFT® will turn off the motor, but it's still important to be alert. For maintenance, clean the tool regularly, especially after use in dusty conditions. Use the included grease to lubricate moving parts as needed. Keep the tool in a dry place and store the battery in a cool environment. Check the torque - limiting clutch and other components periodically for any signs of wear or damage.
