5. Among many considerations the following should particularly be noted Blower casing and associated piping or accessories may become hot enough to cause major skin burns on contact Internal and external rotating parts of the blower and driving equipment can produce serious physical injuries Do not reach into any opening in the blower while it is operating or while subject to accidental starting Cover external moving parts with adequate guards Disconnect power before doing any work and avoid bypassing or rendering inoperative any safety or protective devices If blower is operated with piping disconnected place a strong coarse screen over the inlet and avoid standing in discharge air stream Avoid extended exposure in close proximity to machinery with high intensity noise levels Use proper care and good procedures in handling lifting installing operating and maintaining the equipment Other potential hazards to safety may also be associated with operation of this equipment All personnel working in or passing through the area should be warned by signs and trained to exercise adequate general safety precautions Hearing protection may be required depending on silencing capabilities INTRODUCTION CONGRATULATIONS on your purchase of a new TI850 Industrial Rotary Positive Displacement Blower from Tuthill Vacuum amp Blower Systems Please examine the blower for shipping damage and if any damage is found report it immediately to the
