FAQs
What type of bits does the DH40MC use?
The DH40MC uses SDS-Max bits, which are designed for heavy-duty rotary hammer applications.

The DH40MC offers 13% faster drilling speed and 28% more demolition performance compared to the DH40MR.
Can I use standard drill bits with the DH40MC?

How often should I clean the SDS-Max chuck?
It is recommended to clean the SDS-Max chuck regularly, especially after use in dusty conditions, to ensure proper bit locking and tool longevity.
What is the warranty period for this tool?
Please refer to the official HiKOKI warranty documentation for the most accurate and up-to-date warranty information, as it can vary by region and purchase date.
Is this tool suitable for light-duty tasks?
While powerful, the DH40MC can be used for lighter demolition or drilling tasks if the appropriate settings and bits are used. However, its primary design is for heavy-duty work where its increased power is most beneficial.
Troubleshooting
Hammer not delivering full impact
Ensure the correct SDS-Max bit is fully seated and locked in the chuck. Check if the bit is worn or damaged. Verify that the tool is not overheating.
Drilling is slow or ineffective
Confirm you are using a sharp, compatible SDS-Max drill bit. Ensure the drill bit is not clogged with debris. Check the material being drilled; some hardened concrete may require different techniques.
Tool overheating quickly
Ensure the air vents are clear of dust and debris. Avoid running the tool continuously at maximum load for extended periods beyond its designed duty cycle. Allow the tool to cool down between heavy tasks.
Excessive vibration
Ensure you are using appropriate PPE (Personal Protective Equipment), including anti-vibration gloves. Maintain a firm grip and use a two-handed technique. Check for bit damage, as a damaged bit can increase vibration.

Setup, Compatibility & Care
Setup: Ensure the tool is unplugged before inserting or removing bits. Insert the SDS-Max bit into the chuck and push it in while turning slightly until it locks firmly into place. Refer to the user manual for specific instructions on attaching auxiliary handles.
Compatibility: This hammer is exclusively compatible with SDS-Max bits. Ensure you are using genuine HiKOKI bits or high-quality third-party SDS-Max bits for optimal performance and safety.
Care: Regularly clean the exterior of the tool with a dry or slightly damp cloth. Keep the SDS-Max chuck free of dust and debris; a small brush can be used for cleaning. After use, particularly in dusty environments, clean the vents to ensure proper cooling. Store the tool in its case in a dry environment. Periodically check the power cord for any damage.
