    • SAWZALL J. Snively | A. Berta HISTORY The reciprocating saw came into fashion by Milwaukee Electric Tool Company. The company patented the name “Sawzall” in 1951. Billed as the first portable electric hacksaw, the design has gone on by other tool companies under the name reciprocating saw. DeWalt, Black & Decker, Ryobi and others have duplicated Milwaukee’s Sawzall. But the name remains Milwaukee’s.
    • SAWZALL J. Snively | A. Berta COMMON EXTERNAL PARTS
    • SAWZALL J. Snively | A. Berta INTENDED USES & OVERVIEW The Sawzall gets it name from Milwaukee tools, is a reciprocating saw. Used heavily in construction, and used by most trades: plumbing, electrical, and carpentry. Models will have minimum and maximum speeds measured in Strokes Per Minute (SPM). The harder you squeeze the saw’s trigger the faster in will move the blade. Usually at speeds of 1700 spm is considered minimum up to 2700spm at maximum. Blades can be damaged at slower speeds, when using a Sawzall make sure of attaining maximum speed before cutting. The cutting stroke size is one inch and one eighths inches that means the distance the blade moves forward on a single cutting stoke. Some Sawzall models come with an orbital cutting mode. To turn that function on there is a shift lever on the Sawzall Fig. 1. When the Sawzall is cutting in this mode the blade cuts in a push pull manner plus in a slight circular motion.
    • SAWZALL J. Snively | A. Berta INTENDED USES & OVERVIEW The Sawzall is intended to replicate the motion of a hacksaw or Jigsaw but on a larger scale. Its handle and saw placement make it very Fig. 1 comfortable for vertical cuts. The blade cuts in a push pull manner Fig. 2. Primarily used for rough work, a Sawzall cuts holes for pipes, cooling ducts and roof vents. Because of the blade placement the Sawzall can get into hard to reach areas. Although, very close in application to a saber saw the Sawzall is Fig. 2 heavier and more powerful. The Sawzall makes true of its name by cutting just about anything from Wood, metal, plastic, ceramics. It is a multi use instrument and is used for demolition work as well. The blade drives forward and back for its cutting motion

    • SAWZALL J. Snively | A. Berta GENERAL OPERATIONS As mentioned before, generally used for rough cutting applications the Sawzall has a few features that make this as easy as Fig. 3 possible starting with the shoe Fig. 3. At the back of the blade, the shoe is there to help guide and allows you to turn the blade on a bevel or a slant without splintering your work. Also the shoe helps to insure there is no kick back when cutting because the saw can rest on the shoe as the blade cuts through the given material. Adjustable Shoe

    • SAWZALL J. Snively | A. Berta SAFETY & PRECAUTIONS Safety at the workplace is the number one rule. When operating a power tool or any tool for that matter there are a few key points to follow to be as safe as possible. General safety includes: • Do Not operate while under influence of Drugs, Alcohol or certain medications • Make all loose fitting clothing, long hair, jewelry secure- It can be caught in the moving parts of machinery • Always wear safety shoes or boots • Do not remove guides or safety features such as shoe and safety switches • Be aware of other workers and hazards on jobs site i.e. electrical wires, gas pipes, working water pipes etc…
    • SAWZALL J. Snively | A. Berta SAFETY & PRECAUTIONS Sawzall specific safety rules can include: • Always use two hands unless specific jigs are available • Wear face shield or safety glasses when cutting material • Unplug Sawzall when changing blades
    • SAWZALL J. Snively | A. Berta TIPS & TECHNIQUES Using a Sawzall for most applications its use can be straight forward but there are different techniques and ways to make the best cut possible such as: • Use a lower cutting speed for cutting metals • For thin sheet metal clamp small piece of wood to the back to reduce tear out • Bead a thin layer of oil to lubricate metal while cutting • Higher speeds are recommended for cutting wood • Use correct blade for certain material to insure no burn marks • Flexibility in the blades allow a flush cut along walls and floors by applying pressure to the blade and bending it flush to surface
    • SAWZALL J. Snively | A. Berta JIGS & ACCESSORIES Although the Sawzall is a great tool there is always ways to improve performance. There are a couple of jigs/clamps available so that when there is need for a straight cut you can place the saw blade into this jig that clamps on to the surface of a pipe, you are about to cut and makes a straighter cut. It is call the pipe clamp system. There are also numerous blades you can have for all types of cutting: • All purpose blades for general use to cut wood, nail embedded wood, composite material, plastic, ferrous and non ferrous metals, cast iron range from 4” to 12” and have 8 to 14 teeth per inch • Ice Hardened blades recommended for nail embedded wood range from 6” to 9” length and have 8 to 24 teeth per inch
    • SAWZALL J. Snively | A. Berta JIGS & ACCESSORIES • Ice Hardened Torch blades recommended for metal range from 6” to 9” length and have 10 to 18 teeth per inch • Metal cutting blades recommended for Conduits, tubing, channels, pipe, rubber, fiber, trim range 4” to 12” length and have 14 to 24 teeth per inch • Plaster cutting blades recommended for plaster, plaster with metal lath, plasterboard. It cuts on both forward and backward strokes are 5” length and have 6 teeth per inch • Pruning blade recommended for pruning trees, smooth sawing green wood range from 9” to 12” length and have 5 teeth per inch • Scroll cutting blades recommended for scroll cutting wood. Contours, nail embedded wood, plastics range are 3 5/8” length and have 10 to 18 teeth per inch • Tungsten-carbide blade come with a grit type between medium to coarse grit recommended for hardwood flooring, cast iron, stainless steel, fiberglass materials (polyesters, epoxies, melamine’s), ceramic tile, stone, carbon, brick, clay pipe, marble, plaster. Chalkboard range from 3 ½” to 9” length and there are no teeth just a grit type on cutting edge of blade
