English 10. Adjusting the swing cutting operation Two cutting systems can be selected with this unit. The first is straight cutting, in which the saw blade is moved linearly, and the second is the swing cutting, in which the saw blade is swung like a pendulum. (Fig. 14, Fig. 15) (1) Straight cutting You can perform straight cutting by setting the change lever widthwise. Straight cutting should normally be performed when cutting hard materials such as metal, etc. (Fig. 14) (2) Swing cutting You can perform swing cutting by setting the change lever lengthways. Swing cutting should normally be performed when cutting soft materials such as wood, etc. Swing cutting is efficient since the saw blade forcibly bites into the material. (Fig. 15) Straight Cutting Change Lever Fig. 14 Change Lever Swing Cutting Fig. 15 CAUTION: ⅜ Even for soft materials, you should perform straight cutting if you wish to make curved or clean cuts. ⅜ Dust and dirt accumulated on the change lever section can degrade the function of the change lever. Periodically clean the change lever section. HOW TO USE THE RECIPROCATING SAW CAUTION: ⅜ Avoid carrying it plugged to the outlet with your finger on the switch. A sudden startup can result in an unexpected injury. ⅜ Be careful not to let sawdust, earth, moisture, etc., enter the inside of the machine through the plunger section during operation. If sawdust and the like accumulate in the plunger section, always clean it before use. ⅜ Do not remove the front cover (refer to Fig. 2). Be sure to hold the body from the top of the front cover. ⅜ During use, press the base against the material while cutting. Vibration can damage the saw blade if the base is not pressed firmly against the workpiece. Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade. 14
