Makita 80V Max (40V Max X2) XGT Brushless 28 lb. AVT Demolition Hammer Kit, accepts SDS-MAX bits, AWS Capable - GMH02PM

Makita 80V Max (40V Max X2) XGT Brushless 28 lb. AVT Demolition Hammer Kit, accepts SDS-MAX bits, AWS Capable - GMH02PM 

The 80V max (40V max X2) XGT Brushless 28 lb. Demolition Hammer Kit (GMH02PM) 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 15% faster breaking than equivalent corded hammer (HM1213C). 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.

Features

• OUTPOWER: Makita-built brushless motor along with two 40V max XGT® batteries combine to deliver up to 15% faster breaking efficiency than corded equivalent model*
• OUTSMART: Delivers more impact energy than corded*
• Anti-Vibration Technology (AVT) is an internal counterbalance system along with vibration-absorbing handles that work together to reduce vibration
• OUTLAST: Extreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions
• Auto-start Wireless System (AWS) utilizes Bluetooth technology for wireless power-on/off communication between tool and dust extractor (AWSTransmitter sold separately)
• Dust extraction capability with optional Makita Dust Attachment Kit
• Soft start suppresses start-up reaction for improved accuracy
• "Soft no-load" function automatically reduces the speed of the motor when idling to help increase tool life and performance
• Built-in L.E.D. light with an independent on/off switch illuminates the work area

Maintenance Tips

• Remove debris and dust from vents and housing after each use to prevent overheating and maintain performance.

• Inspect SDS‑MAX bits and chuck regularly for wear or damage; replace as needed.

• Grease bit shank and contact surfaces lightly to ensure smooth insertion and reduce wear.

• Check side handle and fasteners for tightness before every job.

• Clean battery terminals and ensure secure connection; charge per battery manual.

• Avoid moisture & harsh chemicals on tool surfaces; wipe with a soft cloth.

• Store in case when not in use to protect from dust and impacts.

• Quick pre‑use check ensures proper AWS and AVT function for safety and efficiency.
