ATTACHING THE BLADE
!WARNING Disconnect the plug from the power source before
making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
1.Press the lock button and turn wrench until lock button engages. Saw shaft is now locked. Continue to depress button, turn wrench clockwise and remove BLADE STUD and OUTER WASHER (Fig. 2).
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 INNER and OUTER washers lay flush against the blade.
5.Reinstall OUTER WASHER. First tighten BLADE STUD finger tight, then TIGHTEN BLADE STUD 1/8 TURN (45˚) 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 a fraction of a turn more (less than 1/8 turn). OVERTIGHTENING THE BLADE STUD NULLIFIES THE EFFECTIVE- NESS OF THE CLUTCH.
