LED WORKLIGHT LED worklight illuminates the cutting area. ELECTRIC BRAKE To stop the reciprocating saw, release the trigger switch and allow the tool to come to a complete stop. The electric brake quickly stops the blade action. This feature engages automatically when you release the trigger switch. ASSEMBLY WARNING! If any part is broken or missing, do not attempt to plug in the power cord, attach the battery, or operate the saw until the broken or missing part is replaced.
OPERATION TO ATTACH BATTERY PACK (Fig. 2) CAUTION: When placing the battery pack on the tool, be sure that the raised rib on the battery pack aligns with the groove on the saw and the latches snap into place properly. Improper assembly of the battery pack can cause damage to internal components. Fig. 2 ATTACH DETACH 1. L ock the trigger switch in the “OFF” position. 2. A lign the raised rib on the battery pack with the grooves on the bottom of the saw, and then attach the battery pack to the saw.
BLADE SELECTION Fig. 4 In order to obtain the best performance from the saw, it is important to select the correct blade for the particular application and type of material to be cut. Blades with fewer teeth, such as those with 10 teeth per inch (TPI), are typically used for cutting wood, while blades with more teeth are LED worklight better for cutting metal or plastic. We recommend 14 TPI for plastics Fig. 5 and soft metals and 18 TPI for hard metals. INSTALLING A SAW BLADE (Fig. 5) 1.
General cutting (Fig. 6a and 6b) WARNING! Before attaching the battery pack on the tool, always check to determine that the switch performs properly and returns to the “OFF” position when released. WARNING! Hold the tool only by the plastic handle and the insulated grip area to help prevent electrical shock. When sawing into walls or floors you may encounter electrical wiring. Sawing into a “live” wire will cause electric shock. Fig. 6a Fig. 6b 1. M ake sure that the workpiece is firmly clamped. 2.
WARNING! Do not allow familiarity with the saw to make you careless. One careless fraction of asecond is enough to inflict serious injury. Fig. 7 NOTE: Cutting speeds should vary with the workpiece. Hard materials, such as metals, require lower speeds; for softer materials use higher speeds. PLUNGE CUTTING (Fig. 7) Your reciprocating saw is ideal for plunge cutting directly into surfaces that cannot be cut from an edge, such as walls or floors. WARNING! Do not plunge cut into metal surfaces. 1.
METAL CUTTING The saw can be used to cut metals, such as sheet steel, pipe, steel rods, aluminum, brass, and copper. Be careful not to twist or bend the saw blade. Do not force. The use of cutting oil is recommended when cutting soft metals and steel. Cutting oil will keep the blade cool, increase cutting action, and prolong blade life. WARNING! Never use gasoline, because normal sparking could ignite the fumes. 1.
