Before servicing or moving an appliance: • Remove the power cord from the electrical outlet, trip the circuit breaker to the OFF position, or remove the fuse. 3. Never interfere with the proper operation of any safety device. 4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY STANDARDS SET FOR HOME APPLIANCES. 5. GROUNDING : The standard color coding for safety ground wires is GREEN , or GREEN with YELLOW STRIPES .
