Frequently Asked Questions

1. How long does the 4.0Ah battery take to charge? With the included 4A fast charger, the 4.0Ah battery typically reaches a full charge in approximately 60 minutes.

2. Can I use 125 mm discs with this grinder? This model is specifically designed for 115 mm discs. Using larger discs is not recommended as it requires removing the safety guard, which is a significant safety hazard.

3. Does the "Brushless" motor really make a difference? Yes. Brushless motors are more efficient because they don't lose energy through friction. This results in longer battery life and a cooler-running motor that lasts years longer than brushed equivalents.
