Makita 40V Max XGT Brushless Cordless 15 lb. SDS‑MAX AVT Demolition Hammer Kit, AWS Capable (4.0Ah) - GMH01M1

Makita  40V Max XGT Brushless Cordless 15 lb. SDS‑MAX AVT Demolition Hammer Kit, AWS Capable (4.0Ah) - GMH01M1

The 40V max XGT Brushless Cordless 15 lb. Demolition Hammer Kit (GMH01M1) is a cordless concrete solution designed for heavy-load applications. It delivers the power, speed, and run-time for corded demands, without the cord. The demolition hammer delivers up to 20% faster breaking than an equivalent corded hammer (HM0871C). It accepts SDS-MAX bits.

Anti-Vibration Technology (AVT) for reduced vibration. More than just a padded handle, AVT is an internal counterbalance that uses air pressure to move counterweight pistons in the opposite direction of the drive piston to actively reduce vibration. For added durability in harsh job site conditions, Extreme Protection Technology (XPT) is engineered for improved dust and water resistance.

Auto-Start Wireless System (AWS) uses Bluetooth technology for wireless power-on and power-off communication between the equipped tool and dust extractor. Once connected via AWS, the AWS-equipped dust extractor will automatically power on or off when the AWS-equipped cordless tool starts or stops, running only when the tool is in use. This increases productivity on a single charge and reduces continuous noise at the job or work site.

Maintenance Tips

• Clean After Every Use: Wipe dust, concrete chips, and debris from the tool housing, vents, and bit area to prevent buildup that can reduce cooling and performance.

• Inspect SDS‑MAX Bits: Before use, check bits and shanks for wear or debris; lightly grease the bit shank periodically to ensure smooth insertion and reduce chuck wear.

• Tighten Handles & Fasteners: Always ensure the side handle and any attachments are securely tightened before operation for comfort and control.

• Battery Best Practices: Use genuine Makita 40V Max XGT batteries, charge before full depletion, and store batteries in a cool, dry place to extend lifespan and consistent power delivery.

• Dust Extraction Care: If using with a dust extractor (AWS capable), clean filters and connection points regularly to maintain strong dust capture.

• Cooldown After Heavy Use: After prolonged heavy chipping/demolition, let the tool cool before continuing to protect internal components.
