Always be sure the equipment is properly grounded.

Always turn the main electrical panel off and lock it out in accordance with published lockout/ tagout procedures prior to making adjustments, repairs, and maintenance.

Always wear appropriate protective equipment such as safety glasses, safety shoes, hearing protection and hard hats.

Always keep chemical and flammable material away from electrical or operating equipment.

Always maintain a safe work area that is free from slipping and tripping hazards.

Always be sure appropriate safety devices are used when providing maintenance and repairs to all equipment.

Never exceed the rated capacity of a machine or tool.

Never modify machinery in any way without prior written approval of the Besser Engineering Department.

Never operate equipment unless proper maintenance has been regularly performed.
