Using this crankset is easy. First, make sure your bike is suitable for the 150mm length and 107 SQR JIS spindle type. Install the left and right crank arms on your bike following the normal bike - part installation process. Since it doesn't come with a chainring or BB, you'll need to use your existing ones or buy them separately. When using the bike, be gentle with the pedals to avoid excessive stress on the crank arms. For maintenance, regularly clean the crank arms with a soft cloth to remove dirt and debris. You can also apply a light coat of lubricant to keep the movement smooth. If you notice any unusual noises or looseness, check the installation and tighten the parts if necessary.
