NOTES: If the blade clamp collar resists rotation to remove a blade, A Fig. 3 7 work the blade up and down while rotating the clamp (in a counterclockwise direction). If the blade breaks leaving nothing to grasp (to pull it from the clamp), it may be necessary to use another blade as a tool to aid in removing the broken piece (see Fig. 4). While holding the release collar in the open position, use the tip of another blade to “hook” the broken piece and pull it from the clamp. (A thin, fine-toothed, metal- cutting blade works best.) Periodically clean the blade clamp with dry compressed air. DO NOT lubricate the blade clamp. Lubricant can attract contamination. Wear safety glasses while using compressed air. MODEL 738 Disconnect saw from power source before installing or removing blades. 1. Use hex wrench (supplied with Model 738), to loosen blade clamp screw (A) Fig. 5, by turning counterclockwise three to four turns. 2. Insert the blade into the blade clamp until it bottoms, (A) Fig. 6. When the blade is properly positioned: the hole in the blade shank will align with the hole (B) Fig. 7, in the backside of blade clamp. 3. Firmly tighten clamp screw. 4. To remove blade, loosen blade clamp three to four turns and pull blade from clamp.

TO PREVENT ACCIDENTAL ELECTRICAL SHOCK THE SAW MUST BE HELD AS SHOWN IN FIG. 8, AND HAVE THE RUBBER FRONT HOUSING COVER PROPERLY INSTALLED AND NOT DAMAGED. Fig. 8 TO START AND STOP SAW 1. Make sure power circuit voltage is the same as shown on the specification plate on the saw. Connect saw to power circuit. 2. Hold saw firmly. Squeeze trigger switch (A) Fig. 9, to start motor. Release trigger to stop motor. A Fig. 9 VARIABLE SPEED The saw is equipped with a variable speed control (0 to 2600 SPM). As the switch trigger is squeezed, the speed of the saw blade increases. The lower speeds are recommended for most metal cutting, while the higher speeds are recommended for wood. A few practice cuts at various speeds (on scrap material), will aid you in choosing the best speed for obtaining the desired results on your application. 9 DUAL BLADE MOTION (Model 737 only) Model 737 has dual blade motion: you have a choice of straight reciprocating motion, as shown in Fig. 10, or orbital motion as shown in Fig. 11. Straight reciprocating motion should be used for all metal cutting operations, and for wood cutting applications where finish is more important than speed. Orbital motion is used for fast cutting of wood. To set saw for straight reciprocating motion: rotate knob (A) Fig. 10, clockwise so that the bar is vertical (arrow pointing to I), as shown in Fig. 10. To set saw for orbital motion: rotate knob (A) Fig. 11, counterclockwise so that the bar is horizontal (arrow pointing to II), as shown in Fig. 11. >> << A Fig. 10 A Fig. 11 PIVOTING GUIDE SHOE The shoe (A) Fig. 12, serves as a rest while making a cut. It is pivoted so the saw may be gradually raised to a position perpendicular to the work as the saw is moved toward the operator. Do not operate the TIGER SAW® with the guide shoe removed. A Fig. 12 10 OPERATIONS BEFORE YOU START TO WORK Select the blade best suited for the material to be cut (see ACCESSORIES). For greatest economy, use the shortest blade suitable for the thickness of the material to be cut. Be sure the material to be cut is rigid. Small work pieces should be securely clamped in a bench vise or with clamps to the work table. As the work progresses in scroll or curved cut-out pieces, the material may be readjusted to accommodate the movement of the saw. If the work is large enough, it may be held only by hand across saw horses. The saw cuts freely with only slight feed pressure. Forcing the saw will not make it cut faster. SAWING WOOD The TIGER SAW® is used much the same as a hand saw in that it is moved toward the operator during the cutting operation. However, since the blade cuts on the up-stroke instead of the down-stroke as in the case of the hand saw, the good or finish side of the work should face down during the cutting operation. PLUNGE CUTS The TIGER SAW® can be used for plunge cutting wood, plywood, wallboard, and plastic materials. DO NOT attempt to plunge cut metal. Clearly mark line of cut on the work. Grasp front housing with one hand and rear handle with the other hand. To start cut, rest saw on shoe bracket, align blade with the marked line of cut, (blade NOT touching work), as shown in Fig. 13. Start saw. Using bracket as a pivot point, roll saw forward by raising rear handle, as shown in Fig. 14. When blade has cut through the work, continue raising the rear handle until saw is perpendicular to the work surface. Keep saw in this position and move blade along line of cut. SA...
