< Disassembly and cleaning of the tool-less blade detachable mechanism >
The tool-less blade detachable mechanism can be easily disassembled or reassembled because the fixing
bolt can be loosened or tightened without removing the front cover. To disassemble the tool-less blade
detachable mechanism, remove the fixing bolt and pull out the blade holder.
CAUTION: This is a special bolt comprised of an M4 thread and an M5 hexagonal socket. Be careful
not to break the bolt by overtightening.

In case the saw blade is apt to come off
The saw blade is apt to come off if the blade hole is worn out. Replace the saw blade with new one. If the
new saw blade comes off even after replacement, the holder pin may be worn out. Replace the holder pin
with new one.
Refer to the Handling Instructions for detailed information about saw blade replacement.

The Model CR 18DMR is convenient for cutting materials on the floor or near window frames, and also for
plunge cutting on plywood panels because the saw blade can be installed upside down.
Refer to the Handling Instructions for detailed information about plunge cutting on plywood panels.
