The Bauer 7" Angle Grinder with Twist Handle, model 1962E-B, is a corded power tool designed for various operations including grinding, sanding, wire brushing, polishing, and abrasive cutting-off. It is intended for professional use and requires adherence to strict safety guidelines outlined in its comprehensive owner's manual.

Function Description:

This angle grinder is a versatile tool capable of performing multiple tasks by attaching different accessories. As a grinder, it can be used for surface grinding applications. With appropriate accessories, it transforms into a sander, a wire brush for cleaning and surface preparation, a polisher for finishing tasks, or an abrasive cut-off tool for slicing through various materials. The twist handle design likely offers ergonomic benefits, allowing for improved control and reduced operator fatigue during extended use. The tool is designed to be operated with both hands for maximum control and safety, especially when resisting kickback forces.

Important Technical Specifications:

Electrical Rating: 120VAC / 60Hz / 15A. This indicates it's a standard household voltage tool with a significant current draw, suggesting powerful performance.
No Load Speed: 8500/min (revolutions per minute). This high speed is crucial for effective grinding, sanding, and cutting operations.
Max. Accessory Diameter: 7" (180mm). This specifies the maximum size of grinding wheels, sanding discs, or other accessories that can be safely used with the tool.
Max. Accessory Thickness: 0.3". This limit ensures compatibility with standard abrasive wheels and prevents overloading the tool or accessory.
Arbor Hole Diameter: 5/8". This is the standard size for the mounting hole on accessories.
Spindle Thread: 5/8" - 11 TPI. This specifies the threading on the spindle for securely attaching threaded accessories and flanges.

Usage Features:

Auxiliary Handle: The tool is equipped with an auxiliary handle that can be installed in one of three positions (either side or on top of the gear housing). This feature is critical for maintaining a firm grip and control, especially to resist kickback and torque reactions during start-up and operation. The manual explicitly states not to operate the tool with one hand or without the auxiliary handle properly installed.
Wheel Guard: A robust wheel guard is a mandatory safety feature. It is securely attached to the gear housing and can be rotated to shield the operator during planned work. The guard helps protect against broken wheel fragments and accidental contact.
Spindle Lock Button: This button allows the user to lock the spindle, facilitating the safe and easy installation or removal of accessories. It is crucial not to depress the spindle lock during starting or operation.
Trigger and Trigger Lock: The tool is activated by a trigger. A trigger lock button is provided to engage continuous operation, reducing strain on the operator's hand during prolonged use. The manual advises ensuring the trigger is not locked on before plugging in the tool and to release the trigger or press and release the lock-on button to stop the tool.
Accessory Compatibility: The tool is designed to accept non-threaded grinding wheels, sanding discs, sanding flap discs, wire wheels, or wire cup brushes, provided they meet the specified diameter, thickness, arbor hole, and RPM ratings. Specific instructions are given for installing both non-threaded grinding wheels (using inner and outer flanges) and threaded accessories.
Workpiece and Work Area Setup: Emphasizes the importance of a clean, well-lit work area, securing workpieces with vises or clamps, and routing the power cord safely to prevent hazards.
Operating Angle: For optimal performance and smoother surfaces, the manual recommends applying the wheel to the work material at a 10° – 15° angle and allowing the tool to operate at full speed. Lighter pressure is advised if the tool bogs down.

Maintenance Features:

Regular Inspection: Before each use, the tool should be inspected for loose hardware, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, and any other condition that might affect its safe operation.
Cleaning: After use, external surfaces should be wiped with a clean cloth. Periodically, dust and grit should be blown out of the motor vents using dry compressed air, while wearing appropriate eye and breathing protection.
Accessory Handling and Storage: Accessories should be handled carefully to prevent damage. They should be stored in a dry place, above freezing temperatures, and protected from humidity. Damaged or dropped wheels must not be used.
Professional Servicing: Procedures not explicitly explained in the manual, such as replacing carbon brushes or addressing internal damage, must be performed only by a qualified technician. If the supply cord is damaged, it must be replaced by a qualified service technician.
Troubleshooting Guide: The manual includes a troubleshooting section to help diagnose common issues like the tool not starting, operating slowly, decreased performance, excessive noise, overheating, or ineffective grinding/sanding/brushing. Solutions range from checking power connections and accessory installation to seeking professional service.

The Bauer 7" Angle Grinder is a robust tool that, when used according to the provided safety warnings and instructions, can be a valuable asset for various material processing tasks. Its design prioritizes user safety through features like the wheel guard, auxiliary handle, and spindle lock, while its technical specifications indicate a powerful and efficient performance capability.
