ATTACHING THE BLADE

Disconnect the plug from the
power source before making
WARNING
any assembly, adjustments or changing
accessories. Such preventive safety measures
reduce the risk of starting the tool accidentally.
Use only 8 1/4" blade rated
4700/min (RPM) or greater.
WARNING
Using blade not designed for the saw may result
in serious personal injury and property damage.
1. Press the lock button and turn wrench until
lock button en gages. Saw shaft is now locked.
Continue to depress button, turn wrench
clockwise and remove BLADE STUD and
OUTER WASHER (Fig. 2).
2. Make sure the saw teeth and arrow on the
blade point in the same direction as the arrow on
the lower guard.
3. 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.
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 ex cessive
resistance, thus reducing saw's tendency to
KICKBACK.
One setting may not be sufficient for cutting all
materials. If ex cessive 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.
