Before making any adjustments or when changing blades, always remove the plug from the power source first. Failure to observe this will lead to serious personal injury. Inserting and Removing Saw Blades: 1. Make sure saw is unplugged from power source. 2. Use the 3mm Allen® Wrench supplied to loosen the setscrew located in the slot on the left hand side of the saw (see Figure 3 for location of controls). While it is not required to remove the screw, it does need to be turned three or four times to allow blades to be exchanged. Please note the locating pin under the jaw clamp. (Figure 2). 3. Remove the blade and replace with blade that has appropriate shank profile (see Figure 1). Make sure the blade has the correct tooth count per inch for the job to be done. 4. Tighten the screw while ensuring the locating pin remains in the hole provided for it in the blade. Always check to see if the blade is secure after the setscrew is tight. Grasp the back side of the blade (the side without teeth) and gently try to move it side to side and back and forth. If the blade is found to be loose, remove the screw and reposition the blade. Blade Locating Pin Fig 1. Always use correct shank profile. Fig 2. Blade Clamp Assembly. Continuous Run Mode: The trigger switch can be locked by pressing the button on the side of the handle. Squeeze the trigger switch until it has reached the required position and depress the lock on the knob. This will make the tool run continuously. Press the trigger switch to disengage the lock (see Figure 3). H0799 Reciprocating Saw -5 OPERATION, CONT’D Choosing the Right Blade: The rule of thumb for choosing a blade for a given application is that the harder and/ or thinner the material, the more teeth per inch are required. A list of TPI and materials to be cut follows. TPI Material 24 Sheet Metal / Stainless 14 Metal / Wood w/ Nails 10.14 Soft Metals / Wood 10 Wood 6 Rough Cut Wood Choosing the Blade Speed: Blade speed is controlled by the thumb wheel on top of the saw, above the trigger (see Figure 3). The higher the number on the thumbwheel, the faster the saw reciprocates. Using the right blade and speed will allow faster cutting operation, longer blade life and will prolong the life of the saw. This will require practice on the part of the operator. If blade seems to dull quickly, replace and use slower blade speed. If cutting wood, most species allow faster speeds. NOTE: When cutting metal, a suitable coolant must be used (cutting oil); otherwise it will cause unnecessary wear on the blade. Stroke Length and Material Thickness: The length of stroke for the H0799 Reciprocating Saw is 13.16". When material thickness exceeds 13.16" the blade is unable to evacuate the chips being produced. Therefore, when cutting materials that are thicker than 13.16" it may be necessary to "clear the blade" occasionally. Simply let go of the trigger and allow the blade to come to a complete stop. Extract the blade from the cut and the chips should fall away. Insert the blade into the cut and continue cutting. Never extract or insert the blade into workpiece with the blade in motion. Serious personal injury will occur. Setscrew Lock Switch On/Off Blade Speed Thumbwheel Fig 3. Location of controls. Operating this equipment has the potential to propel debris into the air which can cause eye injury. Always wear safety glasses or goggles when operating equip- ment. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI). -6-H0799 Reciprocating Saw OPERATING TIPS AND Operating Guides and Tips Avoid overloading the saw. Always use sharp blades. Do not apply excessive pressure to the saw while using. If the speed drops abnormally, decrease pressure immediately. If the blade stops abruptly or becomes locked, release the trigger at once. Extract the blade and determine what occured to cause this and rectifiy. Ensure the safety of the workplace. Ensure the saw blade will not pass through bench or saw horse that workpiece may be on. Securely fix smaller objects to be cut in a vise or otherwise clamp to avoid injury. Do not attempt to hold workpiece by hand. Avoid blade pinch. Saw blades may become pinched while cutting a work- piece that is improperly supported, very thick workpieces or when several workpieces are loosely stacked. Know how to avoid these situations to minimize risk of damage to the saw, saw blade or personal injury. Inspect the saw before use. Run the saw before using to ensure all parts are running smoothly and there are no abnormal sounds or sparks. If any defect is found, have unit serviced. Know your worksite. Only cut as deep as necessary. Be extr...
