5. Setup and Assembly

5.1. Attaching the Side Handle

1. Loosen the side handle clamp by rotating it counter-clockwise.
2. Slide the side handle onto the front barrel of the rotary hammer.
3. Adjust the handle to a comfortable and secure position.
4. Tighten the clamp by rotating it clockwise until the handle is firmly secured.

5.2. Installing the Depth Gauge

1. Insert the depth gauge rod through the hole in the side handle clamp.
2. Adjust the depth gauge to the desired drilling depth. The distance from the tip of the drill bit to the end of the depth gauge indicates the drilling depth.
3. Secure the depth gauge by tightening the clamp on the side handle.

5.3. Inserting SDS Drill Bits

1. Clean the shank of the SDS drill bit.
2. Pull back the chuck collar on the rotary hammer.

6. Operating Instructions

6.1. Selecting Operating Mode

The Chicago Electric 3-in-1 SDS Rotary Hammer offers three operating modes:

• Drill Mode (Rotation Only): For drilling into wood, metal, and plastics without hammering action.
• Hammer Drill Mode (Rotation with Hammering): For drilling into concrete, brick, and masonry. This is the primary mode for hard materials.
• Chisel Mode (Hammering Only): For light chipping, chiseling, or breaking applications (e.g., removing tiles). The rotation is disengaged in this mode.

To select a mode, rotate the mode selector switch to the desired icon. Ensure the tool is unplugged before changing modes.

6.2. General Operation

1. Ensure the correct drill bit or chisel is securely installed for your task.
2. Set the depth gauge if a specific drilling depth is required.
3. Connect the power cord to a suitable electrical outlet.
4. Hold the tool firmly with both hands, using the main handle and the side handle.
5. Position the drill bit at the desired drilling point.
6. Press the variable speed trigger to start the tool. Begin with a slow speed for better control, then increase as needed.
7. Apply steady, even pressure. Do not force the tool; let the tool do the work.
8. When finished, release the trigger and wait for the bit to stop rotating before setting the tool down.
9. Unplug the tool from the power outlet after use.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your rotary hammer. Always unplug the tool before performing any maintenance.
