Frequently Asked Questions - H 45MA HITACHI
How to change the chisel or drill bit on the H 45MA?
Use the provided key to unlock the SDS-Max tool holder. Insert the tool to the stop, then turn slightly to lock. To remove, pull the locking ring back and remove the tool.
What type of oil should I use for lubrication?
Use a special grease for rotary hammers available from Hitachi. Do not use engine oil.
The drill bit does not rotate, what should I do?
Check that the mode selector is in the 'drilling' position (drill symbol) and not in 'chiseling' only. If the problem persists, the carbon brushes may be worn.
How to adjust the drilling depth?
Use the adjustable depth stop by turning the knob on the side of the hammer. Lock with the clamping screw.
The hammer vibrates strongly, is this normal?
Some vibration is normal, but if it becomes excessive, check the condition of the tool holder and tools. Use anti-vibration gloves.
Can I use an adapter for round shank bits?
No, the H 45MA only accepts SDS-Max shank tools. Using adapters may damage the device.
How to clean the ventilation slots?
Use a vacuum cleaner or a soft brush to remove dust. Never use solvents.
Where to find replacement carbon brushes?
Replacement carbon brushes (reference 326206) are available from Hitachi authorized dealers or online.
The power cable is damaged, what to do?
Cable replacement must be carried out by an authorized after-sales service for safety reasons.
