Introduction

This special instruction contains the procedure to reinforce the frame of HF201 Felling Heads and HF221 Felling Heads. The procedure includes instructions for fabrication of the plates that are used to reinforce the frame.

Do not perform any procedure in this publication until you understand the information that is contained in this publication.

Safety

Show/hide table

Personal injury or death can result from fumes, gases and ultraviolet rays from the weld arc. Welding can cause fumes, burn skin and produce ultraviolet rays. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing area. Wear eye, ear and body protection before working. Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death. Read and understand the manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts. See "American National Standard Z49.1, Safety in Welding and Cutting" published by the American Welding Society. American Welding Society 2501 N.W. 7th Street Miami, Florida 33125 See "OSHA Safety and Health Standards, 29 CFR 1910", available from U.S. Department of Labor. U.S. Department of Labor Washington, D.C. 20210

Personal injury can result from flame cutting or welding on painted areas. The effect of gasses from burned paint is a hazard to the person doing the cutting or welding. Do not flame cut or weld on painted areas.

Required Parts

All parts for this procedure must be fabricated. Refer to the appropriate list for the frame that is being repaired. Illustrations of the parts are included in this instruction. Refer to ""Fabrication Drawings" ".
