The Bauer 2144C-B is a 20V cordless rotary hammer designed for drilling and chiseling. Before using the tool, ensure the battery is fully charged and the work area is clear. Always wear appropriate personal protective equipment, including eye, ear, and respiratory protection. The tool features three distinct modes: Drill, Hammer/Drill, and Chisel. Always stop the motor before changing modes or bits.
Device overview
The tool consists of a variable speed trigger, directional switch, mode selector, auxiliary handle, and chuck sleeve. The auxiliary handle can be adjusted for better control, and the depth gauge allows for precise drilling depth.
Setup and preparation
- Charging: Charge the battery pack fully before the first use. Follow the instructions provided with your specific battery charger.
- Auxiliary Handle: Turn the handle counterclockwise to loosen the band, rotate to the desired position, and turn clockwise to secure.
- Depth Gauge: Press the depth gauge lock, insert the gauge to the desired depth, and release the lock.
- Bit Installation: Clean the loading end of the bit and lubricate it with grease. Pull back on the chuck, insert the bit, twist until it seats, and release the chuck. Ensure the bit is secure by pulling on it.
Operating modes
Use the Mode Selector to choose the function. Only adjust the mode when the motor is stopped.
- Drill: For standard drilling.
- Hammer/Drill: For drilling into masonry or concrete.
- Chisel Adjustment: Used to set the angle of the chisel bit.
- Chisel: For chiseling applications.
Maintenance and care
- Cleaning: Wipe external surfaces with a clean cloth after use.
- Lubrication: Lubricate the bit shank with grease before each installation to maintain the internal mechanism.
- Storage: Store the tool, battery, and charger in a dry, indoor area away from children and metal objects.
- Battery: Recycle or dispose of Li-Ion batteries properly. Do not incinerate or open.
Safety warnings
Always use the auxiliary handle to maintain control. When drilling, brace the tool properly. If the bit jams, release the trigger immediately. Be aware of hidden wiring when drilling into walls. Use NIOSH-approved respiratory protection when drilling concrete to prevent silicosis.
