FAQs
Is the battery included with the Makita DHR243Z?
No, the Makita DHR243Z is a 'Bare Tool' and does not include a battery or charger. These must be purchased separately.
What type of drill bits does this tool use?
This rotary hammer uses SDS-plus bits. It also has an optional adapter for standard drill bits, sold separately.
How do I switch between drilling and hammering modes?
There is a mode selector ring located near the chuck. Rotate it to select 'Rotation + Hammering', 'Hammering only', or 'Rotation only'.
What is the benefit of the brushless motor?
The brushless DC motor provides higher efficiency, reducing energy loss by up to 30%. This translates to longer runtimes per battery charge and increased tool power.
Can I use this for light demolition work?
Yes, the 'Hammering only' mode is suitable for light chiseling and demolition tasks, such as removing tiles or plaster.
How does the tool reduce vibration?
It features a unique rubber joint construction that separates the tool body and absorbs vibrations, minimizing their transmission to the user and the battery terminals.
What is included in the package if I purchase the DHR243Z?
This bare tool package typically includes the DHR243Z rotary hammer, a Makpac Case, an Inlay for the case, and a 5-piece SDS Set + Chisel.
Troubleshooting
Tool not turning on
Ensure the battery is fully charged and properly inserted. Check if the battery contacts are clean. Try a different compatible battery.
Drilling is slow or weak
Confirm the correct mode is selected. Ensure the SDS-plus bit is sharp and undamaged. Check for any blockages in the vents or chuck. Verify the battery charge level.
Chuck won't accept or release bit
Clean the inside of the chuck and the bit shank. Ensure the bit is SDS-plus compatible and not bent. Pull the chuck collar back fully when inserting or removing the bit.
Excessive vibration
Ensure the tool is set to the correct mode for the task. Check for worn or damaged bits. Clean the chuck mechanism. If vibration persists, contact service center.
