Figure 3: The DCS381 Reciprocating Saw features a 4-position blade clamp for versatile cutting applications, including flush cuts.

5. Operating Instructions

Always ensure the battery is fully charged and properly inserted into the tool before operation. Wear appropriate personal protective equipment.

5.1. DCD771 Drill/Driver

• Speed Selection: Use the speed selector switch (typically on top of the tool) to choose between low speed (0-450 rpm) for high torque applications and high speed (0-1500 rpm) for faster drilling.
• Torque Adjustment: Rotate the clutch collar to select the desired torque setting for fastening screws, preventing overtightening or stripping. Use the drill mode for drilling holes.
• Operation: Squeeze the trigger to start the drill. The harder you squeeze, the faster the drill operates. Release the trigger to stop.
• Forward/Reverse: Use the forward/reverse button near the trigger to change the rotation direction.

Figure 4: The DCD771 Drill/Driver features a two-speed transmission, offering 0-450 RPM for high torque and 0-1500 RPM for high speed applications.

5.2. DCS381 Reciprocating Saw

• Blade Installation: Ensure the blade is correctly installed and secured using the keyless blade clamp (refer to Section 4.2).
• Cutting: Hold the saw firmly with both hands. Place the shoe against the workpiece before starting the cut. Squeeze the trigger to begin cutting. Allow the blade to reach full speed before engaging the material.
• Pivoting Shoe: The pivoting shoe allows for greater control and depth of cut.

5.3. DCS393 Circular Saw

• Depth Adjustment: Adjust the depth of cut to be slightly deeper than the material being cut.
• Bevel Adjustment: The saw can make bevel cuts up to 45 degrees. Adjust the bevel angle as needed.
• Operation: Hold the saw firmly. Align the blade with your cut line. Depress the trigger to start the saw and allow the blade to reach full speed before entering the material. Guide the saw smoothly through the workpiece.
