Bauer 2072C-B - User Manual

The Bauer 20V HYPERMAX™ LITHIUM 6-1/2" Cordless Circular Saw, model 2072C-B, is a portable power tool designed for cutting various materials, primarily wood. It operates on a 20V lithium-ion battery (sold separately), offering cordless convenience for a wide range of cutting tasks. The saw is intended for both professional and DIY use, providing the flexibility to work in locations without immediate access to power outlets.

Function Description:

The circular saw is designed to make straight cuts through workpieces. It features a rotating saw blade that, when powered by the motor, cuts through material. The saw includes a trigger for activation and a trigger lock for safety, preventing unintentional starting. An auxiliary handle provides additional grip and control, enhancing stability during operation. The saw's design incorporates both an upper guard and a lower guard to protect the user from the rotating blade. The lower guard is retractable, allowing the blade to enter the workpiece, and is designed to close automatically after the cut is complete. A work light is integrated to illuminate the cutting area, improving visibility in dimly lit conditions. The saw also features a vacuum port, allowing for connection to a dust extraction system to minimize sawdust and maintain a cleaner work environment.

Usage Features:

Before use, users must ensure the battery pack is fully charged and properly connected to the saw. The saw requires a 3.0 Amp Hour battery or greater for best results, which is sold separately. The saw blade is also sold separately, allowing users to choose the appropriate blade for their specific cutting needs. The saw's cutting depth can be adjusted using a depth lever and depth scale, enabling precise control over the cut depth. This adjustment is crucial to ensure that only a minimal portion of the blade teeth extends below the workpiece, reducing friction and kickback. The saw also allows for bevel adjustments, controlled by a bevel lock lever and bevel scale, to make angled cuts.

When operating the saw, users are instructed to maintain a firm grip with both hands—one on the main handle and the other on the auxiliary handle—to resist kickback forces. The saw should be aligned on the cut line with the larger part of the workpiece to the left of the saw blade. To start, the trigger lock must be pushed in and held, followed by pressing the trigger. It is essential to allow the blade to reach full speed before contacting the workpiece to ensure a clean and controlled cut. For cross-grain cuts, moving the saw slowly can help minimize tearing of wood fibers. The saw should not be used if the lower guard does not move freely or close instantly, as this indicates a potential safety hazard.

The manual emphasizes several safety precautions during use, such as keeping hands away from the cutting area and the blade, and not reaching underneath the workpiece. It also advises against holding the workpiece in hands or across the leg while cutting, stressing the importance of securing the workpiece to a stable platform. When ripping, a rip fence or straight edge guide should always be used to improve accuracy and reduce blade binding. The saw is designed to be used with blades that have correct size and shape arbor holes and are not damaged.

Maintenance Features:

Regular maintenance is crucial for the safe and efficient operation of the Bauer circular saw. Before each use, the tool should be inspected for any signs of damage, including leaking, swollen, or cracked battery packs, loose hardware, misalignment or binding of moving parts, or cracked/broken components. Any condition that may affect its safe operation should be addressed.

After each use, the external surfaces of the tool should be wiped clean with a clean cloth. It is particularly important to clean inside the upper guard, as sawdust accumulation can interfere with the lower guard's operation. The battery pack should be disconnected from the tool and stored in a dry, indoor area, out of reach of children and away from metal objects like paperclips or coins, to prevent accidental shorting.

The manual provides instructions for mounting and removing the saw blade, which is a common maintenance task. This involves holding down the spindle lock button while using the blade wrench to loosen or tighten the blade bolt and washer. Users are reminded to ensure the blade is installed with the directional arrow pointing correctly. If the saw experiences abnormal noise or vibration, or if the switch fails to turn the tool on or off, it indicates a need for professional service. The manual also includes a troubleshooting guide to help users identify and resolve common issues, such as the tool not starting, operating slowly, or exhibiting excessive noise. For technical questions or issues not covered in the manual, users are directed to contact technical support.
