IMPORTANT: Designed to be installed with a 1/8 inch gap between the guard and the belt. ALWAYS FOLLOW OSHA, STATE AND OWNER REQUIRED SAFETY GUIDELINES/REGULATIONS DURING THE INSTALLATION OR OPERATION OF A CONVEYOR SYSTEM. Douglas Manufacturing Co., Inc. strongly recommends that any safety program be supplemented by the use of ANSI B20 that refers to conveyor systems. Never operate, adjust or install equipment on a moving conveyor. Always follow lock out and tag out procedures when working on conveyor systems. Personnel who work on or around conveyor systems must be safety trained and familiar with conveyor systems.
The Guardian™ must be inspected periodically to determine if the unit is in proper working order by inspecting and replacing the urethane seal, inspecting to see if material build-up has occurred and ensuring proper adjustment and tightness of all adjustable bolts. Failure to do so may result in serious injury or death. No idler guard can protect against potential danger in all situations or against all hazards. The Guardian™ is designed to help minimize the potential for danger but cannot guarantee protection in all situations or applications. If you have questions or need assistance please call 205-884-1200 or fax 205-884-1206.
