Frequently Asked Questions

Why won’t my scarifier start?

Check that the safety lock button and switch lever are both engaged. Also ensure the power cable is connected and the socket is working.

What cartridge should I use?

Use the raking cartridge for moss removal and the tine cartridge for deeper scarifying work.

How deep should I set the scarifier?

Start with a shallow setting and increase gradually depending on lawn condition. Avoid setting too deep on first pass.
