Maintenance Tips

• Clean after every use – Remove grinding dust and debris; keep cooling air openings clear so the engine and components stay cool. Avoid pressure washers.

• Inspect diamond tools – Check grinding discs before and after use; tighten or replace when worn to maintain performance.

• Dust extraction connection – Use with a compatible dust extractor for cleaner grinding and reduced airborne silica.

• Secure fasteners & safety features – Ensure all guards, handles and emergency controls are intact before starting.

• Store dry & covered – Keep the grinder in a dry place when idle to prevent corrosion and protect fuel system components.
