What type of drill bits does the DH40SC use?
This rotary hammer accepts SDS-Max shank bits. This system ensures efficient power transfer and quick bit changes for drilling and chiseling.
How do I change the chisel or bit on the DH40SC?
To change a bit or chisel, first ensure the tool is unplugged. Pull back the locking sleeve at the front of the tool, insert the new bit until it clicks, then release the sleeve to lock it in place. Always use the bit grease supplied for optimal performance.
What maintenance is required for the DH40SC?
Regular maintenance includes cleaning the tool after use, lubricating the bit shank with the supplied grease, and inspecting the carbon brushes periodically. Also, keep the air vents clear to prevent overheating.
Does the DH40SC have a safety clutch?
