ATTACHING THE BLADE

!Disconnect battery pack WARNING from tool before making

any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.

1.Turn BLADE STUD with wrench provided clockwise and remove BLADE STUD and OUTER WASHER (Fig. 2). If the shaft moves while attempting to loosen the blade stud press the lock button (Fig. 1).

2.Retract the lower guard all the way up into the upper guard. While retracting the lower guard, check operation and condition of the

LOWER GUARD SPRING.

3.Make sure the saw teeth and arrow on the blade point in the same direction as the arrow on the lower guard.

4.Slide blade through slot in the foot and mount it against the INNER WASHER on the shaft. Be sure the large diameter of the OUTER washer lays flush against the blade.

5.Reinstall OUTER WASHER and tighten BLADE STUD finger tight. The face of upper

guard has marks around it that will help you properly adjust the blade stud. Press lock button to lock shaft and TIGHTEN BLADE STUD COUNTER-CLOCKWISE TWO MARKS ON UPPER GUARD WITH THE WRENCH PROVIDED.

Do not use wrenches with longer handles, since it may lead to over tightening of the blade stud.

VARI-TORQUE CLUTCH

This clutching action is provided by the friction of the OUTER WASHER against the BLADE and permits the blade shaft to turn when the blade encounters excessive resistance. When the BLADE STUD is properly tightened (as described in No. 5 of Attaching The Blade), the blade will slip when it encounters excessive resistance, thus reducing saw’s tendency to

KICKBACK.

One setting may not be sufficient for cutting all materials. If excessive blade slippage occurs, tighten the blade stud one mark more.

OVERTIGHTENING THE BLADE STUD NULLIFIES THE EFFECTIVE-NESS OF THE CLUTCH.
