Makita (HM1213C) 23 lb. AVT Demolition Hammer, accepts SDS-MAX bits, var. spd., case - HM1213C
The Makita 23 lb. AVT Demolition Hammer has a powerful 14 AMP motor that delivers 18.8 ft.lbs. of impact energy to handle the most demanding applications. It weighs 23.8 lbs. The demolition hammer features Anti-Vibration Technology (AVT) and vibration-absorbing rear handle to further reduce vibration. Constant speed control that automatically applies additional power to the motor to maintain speed under load to complete challenging jobs and a variable speed control dial enables users to match speed to the application. The HM1213C has a "soft no-load" function automatically reduces the speed of the motor when not in use which helps increase tool life and performance. The Makita Motor is engineered with field core interlocking steel laminations, dual ball bearing armature and more copper commutator bars, increasing energy transfer efficiency for more power and longer tool life Other features include an L.E.D. power light to indicate switch failure or cord damage and an L.E.D service light that notifies the user that the brushes need to be replaced. An automatic brush cut-off protects the commutator from damage for longer tool life. The 12 bit angle settings allows the bit to be set a different positions for operator comfort. Anti-Vibration Technology (AVT) is a counterbalance system inside the tool that significantly reduces vibration. The AVT counterbalance design is based on seismic engineering, which developed this damping science to absorb shocks and protect buildings from earthquakes. AVT uses a mechanical damper, effectively a counterbalance weight inside the tool, that provides an equal and opposite force that puts a mass directly opposite the point where the striker bolt delivers the impact. As vibration is eliminated, power is efficiently increased which allows more of the generated energy in the motor to be delivered to the tool bit. For users, AVT means significantly less vibration with no compromise in power and performance.

Maintenance Tips
-
Clean after use: Remove concrete dust and debris from the tool body, vents, chuck area, and handles to maintain cooling and performance.
-
Maintain SDS-MAX bits: Clean bit shanks and apply recommended hammer bit grease regularly to reduce wear and ensure smooth bit installation.
-
Inspect the chuck system: Check the SDS-MAX holder for dirt, damage, or excessive wear before installing bits.
-
Monitor carbon brushes: Watch the LED service indicator and replace worn brushes when required to maintain motor performance.
-
Keep vents clear: Clean ventilation openings frequently to prevent overheating during heavy demolition work.
-
Avoid harsh cleaners: Do not use gasoline, thinner, alcohol, or similar chemicals; clean with a soft cloth instead.
-
Service lubrication properly: The hammer uses a grease-packed lubrication system; periodic relubrication should be performed by an authorized service center.
-
Store safely: Clean the tool, remove accessories, and keep it in the carrying case in a dry location to protect it from dust and moisture.
