1. Securely clamp the work.2. Mark the line of cut and grasp the tool withone hand on the handle and the otherplaced on the insulated rubber boot overthe front housing.Always operate the saw withthe insulated boot on the fronthousing. If you saw into a blind area wherelive wiring exists, you may be shocked orelectrocuted.3. Keep the saw footplate firmly against thework to minimize counter-force (jumping)and vibration.4. Squeeze the trigger to start the tool. Let thesaw reach full speed before starting the cut.Guide the saw so that the blade will movealong the marked line.SAWING TIPSFollowing a few simple tips will reduce thewear on the workpiece, the tool and theoperator.1. Blades cut on the draw or back stroke. Onfine work, such as paneling, fiberglass, etc.,place the good side of workpiece facingdown.2. Use the correct saw blade for the materialbeing cut and keep extra blades on hand touse when others become dull. Replacecracked or bent blades immediately.3. Select the appropriate stroke length andfootplate projection settings, as well as theappropriate cutting speed.4. To reduce the risk of injury, be sure theblade always extends beyond the footplateand work throughout the stroke. Bladesmay shatter if the front on the blade hits thework and/or the footplate.5. When cutting metal:- Use the 3/4” (19 mm) stroke length toachieve (less vibration, less heat, andlonger blade life).- Apply a lubricant for easier, smoother,faster cutting and longer blade life.- For non-ferrous metals, aluminum,bronze or brass, use a stick wax on theblade.- For ferrous metals, iron and steel, usemachine or cutting oil along the surfaceto be cut.6. When cutting thin metal, "sandwich" thematerial between two pieces of scrap wood.Clamp or put in a bench vise. One piece oflumber on top of the metal can be used withadequate clamping. Place your cut lines ordesign on the wood. Use the 3/4" (19 mm)stroke for reduced vibration in the material.7. Don’t force the cutting. Let the saw andblade do the work.To remove the footplate assembly forservicing (Fig. 7):1. Remove the blade.2. Press and hold footplate release button in.3. Pull the footplate assembly out as far as itwill go.4. Rotate it clockwise (as viewed from theback of the saw) about 90 degrees until itreleases.5. Pull footplate assembly completely out.To re-insert, reverse this process.Always use tool with thefootplate. Using tool withoutthe footplate will cause instability, expose theblade, and may damage the spindle.FIG. 7! WARNING!
