Follow These Steps to Change Your DeWalt Angle Grinder Blade
Now that you’re equipped with the right tools and an understanding of your angle grinder, let’s move on to the step-by-step process of changing the blade.
Step 1: Prepare and Disconnect
Before you begin, ensure that your angle grinder is turned off and unplugged from the electrical outlet. Safety should always be your top priority.
Step 2: Engage Spindle Lock
Locate the spindle lock on your grinder. Press the spindle lock button while simultaneously turning the blade until you hear a click. This action will lock the spindle in place, preventing any movement during the blade removal process.
Step 3: Remove the Arbor Nut
Using the wrench, turn the arbor nut counterclockwise to loosen it. Some angle grinder models may require you to hold the wrench in one hand while holding the handle of the grinder with the other to maintain stability.
Step 4: Take Off the Blade
Once the arbor nut is loose, carefully remove it along with the flange that holds the blade in place. Gently lift the old blade off the spindle and set it aside.
Step 5: Install the New Blade
Take your new blade and place it onto the spindle, ensuring that it is positioned correctly with the direction of rotation indicated on the blade aligned with the grinder’s housing. Replace the flange and carefully screw on the arbor nut by hand to secure the blade in place initially.
Step 6: Tighten the Arbor Nut
Using the wrench, tighten the arbor nut firmly but avoid overtightening, as this could damage the blade or the grinder.
Step 7: Release Spindle Lock
Press the spindle lock button again to disengage it. Spin the blade manually to ensure that it rotates freely and that everything is in place.
Step 8: Safety Check
Before plugging the grinder back in, double-check to ensure all components are installed securely. Make sure there is no visible damage to the blade, the flange, or the arbor nut.
Step 9: Restore Power and Test
Once you have completed these steps, plug your angle grinder back into the electrical outlet. Turn it on briefly at low speed to ensure it operates smoothly and without vibration. If everything sounds good, you are ready to tackle your project.
