their own weight. Support must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
e)Do not use dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding, and kickback.
f)Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
g)Use extra caution when making a “Plunge Cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
Safety Instructions for Plunge-Type Saws
a)Check guard for proper closing before each use. Do not operate the saw if guard does not move freely and enclose the blade instantly. Never clamp or tie the guard with the blade exposed. If saw is accidentally dropped, guard may be bent. Check to make sure that guard moves freely and does not touch the blade or any other part, in all angles and depths of cut.
b)Check the operation and condition of the guard return spring. If the guard and the spring are not operating properly, they must be serviced before use. Guard may operate sluggishly due to damaged parts, gummy deposits, or a
c)Assure that the guide plate of the saw will not shift while performing the “plunge cut” when the blade bevel setting is not at 90°. Blade shifting sideways will cause binding and likely kickback.
d)Always observe that the guard is covering the blade before placing saw down on bench or floor. An unprotected,

coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.
Additional Safety Instructions for All Saws with Riving Knife
a)Use the appropriate riving knife for the blade being used. For the riving knife to work, it must be thicker than the body of the blade but thinner than the tooth set of the blade.
b)Adjust the riving knife as described in this instruction manual. Incorrect spacing, positioning and alignment can make the riving knife ineffective in preventing kickback.
c)Always use the riving knife except when plunge cutting. Riving knife must be replaced after plunge cutting. Riving knife causes interference during plunge cutting and can create kickback. Model DWS520 does not require removal of the riving knife because the riving knife retracts during a plunge cut.
d)For the riving knife to work, it must be engaged in the workpiece. The riving knife is ineffective in preventing kickback during short cuts.
e)Do not operate the saw if riving knife is bent. Even a light interference can slow the closing rate of a guard.
Additional Safety Instructions for Saws
•Wear ear protectors. Exposure to noise can cause hearing loss.
•Wear a dust mask. Exposure to dust particles can cause breathing difficulty and possible injury.
•Use only recommended blades. The saw is designed for use with
