ATTACHING THE BLADE
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 (Fig. 2) and turn
wrench until lock button en gages. Saw shaft
is now locked. Continue to depress button,
turn wrench clockwise and remove BLADE
BOLT and OUTER WASHER (Fig. 3).
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 BOLT finger tight, then TIGHTEN
BLADE BOLT 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
bolt.
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 BOLT 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 bolt a fraction of a turn more
(less than 1/8 turn). OVERTIGHTENING THE
BLADE BOLT NULLIFIES THE EFFECTIVE-
NESS OF THE CLUTCH.
