Turn the saw off using the appropriate switch. Allow the saw's blade to come to a complete stop before you set it down on a flat work surface such as a garage floor.
Inspect the upper portion of the blade guard and locate its adjustment handle; the handle will be attached directly to the top or the back side of the blade guard.
Grasp the guard adjustment handle with one hand while holding the saw firmly down on the ground with the other hand. Place a tip of a boot through the lower portion of the handle for added stability.
Pull or push the blade adjustment handle in the direction you want the guard to turn. Watch the water outlet hose to make sure it doesn't get stretched to a breaking point.
Check the guard to make sure it's in the proper location and won't hinder you from making cuts before starting and operating the saw. If the guard is in the wrong location, stop the saw and repeat the steps above to make the proper adjustments.
