The size and versatility of Check-It-Gauge makes it a great instrument to use when taking measurements at the machine. However, just like with any tool, the correct safety procedures need to be followed. Always make sure the spindles are off and the machine is stopped before starting any measurement. Also, be certain that levers, knobs, buttons, etc. cannot be accidentally engaged, triggering the machine to unexpectedly start, causing injury. Proper safety gear must also be worn.
