Safety Precautions
* Keep equipment and work area clean, dry and neat. Put tools away when you are through using them.* Be sure work area has adequate ventilation.* Always wear protective gloves and aprons, safety shoes and heavy cotton clothing. Keep collars and shirt cuffs buttoned. Turn trouser cuffs down. Be sure trouser legs extend below shoe tops.* Wear a welding helmet or eye shield with proper filter plates when welding or cutting. Use a No. 4 or No. 5 filter for torch brazing, flame cutting and gas welding. Use a No. 10 or No. 12 filter for arc welding.* Keep a CO2 or dry powder fire extinguisher within reach-especially when flame cutting or welding on or near tractors, engines, etc.* Remove all flammable materials, volatile liquids and explosive gases from the welding area or shield them adequately.* Do not weld or cut on containers such as drums, barrels and tanks until you know there is no danger of fire or explosion from their contents.* Always drill a relief hole in a closed compartment, such as a front idler or track roller frame box section, before welding or cutting on it. If this is not done, any moisture inside the compartment can vaporize, causing an extremely high pressure inside the compartment which may lead to an explosion.* Never strike an arc on a cylinder of compressed gas or on any part of a track adjusting mechanism.* Be sure welding cables, electrode holders and clamps are in good repair and properly insulated.* Support large machine components such as scraper bowls and aprons, bulldozer blade, etc. solidly before working under them.* Fasten oxygen an acetylene hoses cylinders securely in the vertical position before using. Observe all safety rules for handling compressed gas cylinders.* Keep oxygen and acetylene hoses from being cut or burned. Inspect oxygen and acetylene hoses periodically for leaks and worn places. Check all connections for leaks before igniting flame. Do not use oil on oxygen fittings.* Provide mechanical air movement over coated or painted surfaces being welded to dispel any toxic fumes that may be produced.Other Recommended Equipment
