Hold the blade steady. Fit the blade nut onto the spindle. Turn the nut by hand to start threading it.
Use a wrench or spanner to tighten the blade nut. Do not overtighten to avoid damage. Tighten firmly to keep the blade secure during use.
Final Checks
Check the blade to make sure it is tight and stable. A loose blade can cause accidents. Use a wrench to secure the blade firmly. The grinder should feel steady when you hold it.
