6Do not use dull or damaged blade.Unsharpened or improperly set blades pro-duce narrow kerf causing excessive friction,blade binding and KICKBACK. Keep bladesharp and clean. Gum and wood pitch hard-ened on blades slows saw and increasespotential for kickback. Keep blade clean byfirst removing it from tool, then cleaning itwith gum and pitch remover, hot water or ker-osene. Never use gasoline.Blade depth and bevel adjusting lockinglevers must be tight and secure beforemaking cut. If blade adjustment shifts whilecutting, it will cause binding and KICKBACK.Use extra caution when making a “PocketCut” into existing walls or other blindareas. The protruding blade may cut objectsthat can cause KICKBACK. For pocket cuts,retract lower guard using Retracting Lever.ALWAYS hold the tool firmly with bothhands. NEVER place your hand or fingersbehind the saw. If kickback occurs, the sawcould easily jump backwards over your hand,leading to serious personal injury.Never force the saw. Forcing the saw cancause uneven cuts, loss of accuracy, andpossible kickback.Push the saw forward at a speed so that theblade cuts without slowing.12.
