FAQs

What is the main advantage of this cordless angle grinder?

The main advantage is the combination of strong, corded-equivalent power with the freedom and portability of cordless operation, making it ideal for various light-duty tasks without being tethered to a power source.

Can I use this grinder for heavy-duty applications?

This model is designed for light-duty cutting and grinding. For very heavy-duty industrial applications, a more powerful or corded model might be more suitable.

What safety features are included?

The grinder includes KickBack Control, Restart Protection, Soft Start, and Overload Protection to enhance user safety and tool longevity.

What is included in the GWS 18V-8 kit?

The kit typically includes the GWS 18V-8 cordless angle grinder, two GBA 4.0Ah batteries, a GAL 18V-40 charger, and an L-BOXX for storage and transport.

How long do the batteries typically last?

Runtime depends on the application and intensity of use. The 4.0Ah batteries provide optimized runtime for increased productivity in typical light-duty tasks.

What size cutting discs does it use?

The grinder is designed for 115mm diameter cutting and grinding discs.

Is the guard adjustable?

Yes, the protective guard is adjustable, allowing you to position it for optimal safety and to direct sparks and debris away from you.

Troubleshooting

Grinder won't turn on.

Ensure the battery is fully charged and correctly inserted. Check if the trigger lock is engaged. Inspect the battery contacts and the tool's internal connections for dirt or damage.

Reduced cutting or grinding performance.

Check the battery charge level; a low battery can cause reduced power. Ensure the correct type of disc is installed and is not excessively worn or damaged. Clean any dust or debris obstructing the tool's vents.

Tool stops unexpectedly during use.

This could be due to overload protection activating. Release the trigger, allow the tool to cool, and ensure you are not forcing the grinder too hard. Check for obstructions that might be causing the motor to strain. If KickBack Control activates, remove the obstruction and restart.

Overheating during operation.

Ensure the ventilation slots are clear of debris. Avoid prolonged use at maximum load without breaks. If overheating persists, allow the tool to cool down completely and check for any internal issues.

Setup, Compatibility & Care

Setup:

  1. Battery Installation: Ensure the GBA 4.0Ah battery is fully charged using the GAL 18V-40 charger. Slide the charged battery onto the grinder's battery port until it clicks securely into place.
