Using the MagSquare 165 is easy. First, decide where you want to hold your steel piece. Turn the On/Off Magswitch Magnet control to 'On' to activate the magnetic force. Place your steel item on the square. Thanks to the multi - plane workholding and strong grip on multiple sides, it will hold firmly. For precise positioning, use the On/Off control to turn it off and adjust as needed. When you're done, turn the control to 'Off'. This will let the debris fall off and keep the square clean. As for maintenance, just wipe it down occasionally. Avoid hitting it hard as it might affect the 90 - degree machining. And when storing, keep it in a dry place.
