NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight. Variable Speed Trigger Switch (Fig. A, E) Lock-Off Button and Trigger Switch Your saw is equipped with a lock-off button 2 . To lock the trigger switch, press the lock-off button on the left. Always lock the trigger switch 1 when carrying or storing the tool to eliminate unintentional starting. To unlock the trigger switch, press the lock-off button on the right. Pull the trigger switch to turn the motor ON. Releasing the trigger switch turns the motor OFF. WARNING: This tool has no provision to lock the switch in the ON position, and should never be locked ON by any other means. The variable speed trigger switch will give you added versatility. The further the trigger is depressed the higher the speed of the saw. CAUTION: Use of very slow speed is recommended only for beginning a cut. Prolonged use at very slow speed may damage your saw. Fig. E English Flush Cutting (Fig. F) The compact design of the reciproc­ ating saw motor housing and shoe permit close cutting to floors, corners and other difficult areas. 1. To maximize flush cutting capabilities, insert the blade shaft into the blade clamp with the teeth of the blade facing up. 2. Turn the saw upside down so you are as close to the work surface as possible. Fig. F 2 1 Cutting (Fig. A, B, D) The blade 10 should extend past the shoe 4 and the thickness of the workpiece throughout the cut. Select the blade best suitable for the material to be cut and use the shortest blade suitable for the thickness of the material. Do not use jigsaw blades with this tool. NOTE: Before cutting any type of material, be sure it is firmly anchored or clamped to prevent slipping. • Place blade 10 and shoe 4 lightly against work to be cut. • Switch on saw motor and allow it to obtain maximum speed before applying pressure. • Always hold saw as shown in Figure D. Whenever possible, the shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and will minimize blade breakage. Wood Cutting (Fig. D, G) 1. Before cutting any type of wood, be sure the workpiece is firmly anchored or clamped to prevent slipping. 2. Place blade and shoe firmly against work to be cut. 3. Switch on saw motor before starting the cut. 4. Always hold saw as shown in Figure D while cutting. Whenever possible, the shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and minimize blade breakage. Fig. G Metal Cutting (Fig. H) 1. Use a finer blade for ferrous metals and a coarse blade for non-ferrous materials. 2. In thin gauge sheet metals it is best to clamp wood to the underside of the sheet. This will ensure a clean cut without excess vibration or tearing of metal. 3. Avoid forcing cutting blade as this reduces blade life and causes costly blade breakage. 9
