Adjusting the grinding angle In order to provide a proper grind the angle of the grinding wheel to the work rest may need to be adjusted. Adjust the angle to the original angle of the blade as provided by the OEM. This is usually 30 degrees. 1. Unplug the grinder and remove the switch safety lock while checking and adjusting the angle. 2. Place the blade to be ground on the table plate so that the bottom, or the grass side of the blade, is flat against the table plate. 3.
