Assembly
ATTACHING THE BLADE
Disconnect battery pack
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.
