for at least an hour. Components inside the machine become very hot, and
can cause a burn if touched.
• Before moving the machine, unplug the power cable from the outlet. If the
cable is unplugged abruptly, it could become damaged. Damaged plugs or
cables can cause an electrical or fire hazard.
• When lifting the machine, use the grips on both sides. The machine could
break or cause an injury if dropped.
