Using this Wera ratchet set is easy. First, select the right socket size for your task and attach it to the 3/8' drive ratchet. You can use the Zyklo speed ratchet feature to quickly turn the socket. For different jobs, just swap out the sockets. When using, make sure not to apply too much force suddenly, as it might damage the tools. After use, clean the sockets and the ratchet with a dry cloth. Store them in a dry place to prevent rusting. This will keep your set in good condition for a long time.
