INTRODUCTION Basic Safety Rules Which Apply to the Use of Pliers.
Description. Two head patterns are available: Standard, also known as bevel nose, and New England, also known as round nose, which is more streamlined. Handles may be plain, slip-on molded plastic, plastic dipped or high dielectric. High leverage patterns are also available, as are pliers incorporating sleeve twisters and threaded bolt-holding openings. Sizes range from 61/4 to 91/4 inches in length. Proper Uses. These are heavy-duty tools designed for the professional engaged in electrical, communications and construction work. Abuse/Misuse. Never expose pliers to excessive heat. Don't rock pliers from side to side when cutting wire. Always cut at right angles. Never use pliers as a hammer, or drop on hard or paved surfaces.

Abuse/Misuse. Never expose these pliers to excessive heat. Never use as a hammer. When to Repair or Replace. Attempts to repair these pliers are not recommended. Discard any plier that is cracked, broken or sprung.
LOCKING PLIER-WRENCHES AND CLAMPS Description. Locking plier-wrenches are available in a variety of sizes with straight or curved jaws. Compound leverage systems lock jaws and hold various shapes and sizes or work.
Proper Uses. These wrenches are combination tools which function as pliers, wrenches, portable vises or clamps. They are not intended to replace open-end or box wrenches because of possible damage to the fitting or fastener. Abuse/Misuse. Do not hammer to tighten jaws or to cut
wire or bolts. Do not expose wrenches or clamps to heat from welding
torches or to contact with welding electrodes. When subjected
to severe vibration such as encountered during riveting, locking
wrenches or clamps holding the work pieces should be wired or
taped closed to prevent accidental opening. Do not use pipe, other
extensions, or hammering to increase torque applied to these tools.
They should never be used as steps or ladders to support personnel. When to Repair or Replace. Avoid excessive wear on working parts by frequent lubrication. Attempts to repair these tools are not recommended. Discard any damaged tool.
INTRODUCTION
TYPES OF CUTTERS Description. There are different head styles and tool configurations ranging in length from 9" to 42" for cutting different materials. Models which have blades that pass each other normally cut only non-ferrous cable. Proper Use. Cutters are used to cut ferrous materials such as steel wire and cable, rod wire rope, aircraft cable, guy strand, fencing, bolts and steel strapping. Other cutters are used for cutting non-ferrous material such as copper and aluminum. Cutters are used in plant maintenance, construction, electrical construction and maintenance, and other operations. Be certain to select the proper cutter for the job. Follow manufacturers' instructions or obtain professional advice. Proper Care. Cutters should be adjusted and lubricated daily when in use. Jaws may be sharpened according to instructions shipped with the cutter. When to Replace. Attempts to repair cutters are not recommended. Discard any cutter which is cracked, broken or shows signs of looseness or play due to wear in the compound leverage toggle. DO'S AND DON'T'S Wear protective gloves and safety goggles when using cutters. Wear safety shoes. Keep cutting tools in good repair; lubricate moving parts only. Don't attempt to use a cutting tool until its proper and safe uses are fully understood. Remember that metal flies when cut. The harder the metal, the farther it will fly. One way to prevent injury from flying metal is to wrap a burlap bag, wiping cloth or rag around the cutting jaws so metal pieces cannot fly. When using a cutter, warn those in the area to take precautionary measures to avoid possible injury from possible flying metal pieces. Don't cut diagonally. Remember that the hardness of the stock being cut is as important as its size. Use all tools as recommended:
Improper cutting may contribute to personal injury or damage to tool.
PROPER USES. These pliers spread snap lock rings used on brakes, transmissions, pedalshafts, clutch shafts and machine tools. Can also be used to spread piston rings. SAFETY TIPS
