How long does the 4.0Ah battery last?

With the included 4.0Ah battery, the Ryobi R18AG7 can deliver up to 80 cuts of 13mm threaded bar on a single charge. Actual runtime will vary depending on the intensity and duration of the task.

Is this grinder suitable for prolonged, heavy-duty use?

While the brushless motor offers excellent durability, for extremely prolonged or heavy-duty continuous use, consider having a spare charged battery on hand to minimize downtime.

How do I activate the anti-kickback feature?

Can I use this grinder for cutting metal and masonry?

Yes, with the appropriate cutting discs for metal or masonry, this grinder can be used for such applications. Always ensure the disc is rated for the material you are cutting and wear appropriate safety equipment.

What is included in the kit?

Troubleshooting

Tool does not start

Ensure the battery is properly inserted and charged. Check if the lock-on switch is engaged correctly. Verify that the safety features are not preventing operation.

Reduced power or speed

The battery may be low on charge; replace with a fully charged battery. Clean any dust or debris from the motor vents. Check the disc for excessive wear or damage, which can increase load.

Tool shuts down unexpectedly

This could be the anti-kickback feature engaging due to a jam. Carefully assess the situation, clear any obstruction, and restart the tool. If the issue persists, check the battery connection.

Excessive vibration

Ensure the grinding or cutting disc is correctly mounted and balanced. Check for any damage to the disc. If vibration persists, consider if the workpiece is securely clamped.
