When looking for a replacement blade, select one with dimensions close to the original blade. This information may not be printed on the blades packaging. If not, check the manufacturers catalog or website. Bosch offers an extensive line

of Premium-Quality Professional Saw Blades that match the requirements for this tool. You must select a blade with a kerf width of .092” or more and a plate (body) thickness .088” or less (Fig. 10).

!	WARNING	To reduce the risk of injury, do not use extra
		thin kerf saw blades. The kerf of the blade

must be wider than .092”. Extra thin kerf saw blades (less than

.092”) may cause the work piece to bind against the riving knife during cutting. It is recommended that the kerf of the replacement blade used on this saw be .092” or more.

!	WARNING	To reduce the risk of injury, do not use saw
		blades made with a thick body plate. If the

replacement saw blade's plate thickness is greater than .088”, the riving knife would not properly serve as an aid to reduce kickback. The replacement blade's plate thickness must be less than .088”.

!	WARNING	To reduce the risk of injury, do not use blade
		“dampeners,” “stabilizers,” or “stiffening

collars” on both sides of a replacement blade. These are metal plates positioned against the sides of the blade to reduce deflection that may occur when using thin saw blades. Use of these devices on both sides will prevent the blade from being properly aligned with the riving knife, which may bind the work piece during cutting. One “stabilizer” plate may be placed only against the outside of a thin replacement blade. These plates are not required with the supplied Bosch blade.

Changing the Blade

1.Turn elevation wheel clockwise until the blade is up as high as it will go, remove table insert 1 using finger hole (Fig. 11).

2.Lift up arbor lock lever 2 and slowly rotate blade by hand until lock fully engages saw arbor and stops rotation (Fig. 11). Loosen arbor nut 3 counter clockwise with the arbor wrench 4 provided (Fig. 12). Set wrench aside and continue to loosen arbor nut 3 by hand and remove arbor nut 3 and outer washer 5. Blade may now be removed or installed by sliding on or off arbor shaft 6.

3.Assemble inner washer 7 and new blade as shown in figure 13, making certain the TEETH OF THE BLADE ARE POINTING DOWN AT THE FRONT OF THE TABLE.

NOTE: The printing on different saw blades are not always on the same side.

4.Assemble outer washer 5, arbor nut 3 as shown in figure 13. While lifting up arbor lock lever 2 securely tighten arbor nut 3 clockwise with the wrench 4. (Fig. 12).

5.Position table insert in pocket of table so tabs 8 on table insert 1 are in slots in pocket of table and push down and secure in place.
