ATTACHING THE BLADE
Disconnect battery pack
from tool before making
any assembly, adjustments or changing
accessories. Such preventive safety mea-
sures reduce the risk of starting the tool acci-
dentally.
1. Turn BLADE STUD with wrench provided
counter-clockwise and remove BLADE
STUD and OUTER WASHER. If the shaft
moves while attempting to loosen the blade
stud press the shaft lock button (Fig. 2).
2. For easier blade change adjust depth of cut
to MINIMUM (see DEPTH ADJUSTMENT
on page 11). Make sure the saw teeth and
arrow on the blade point in the same direc-
tion 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 (See page 11).
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. Press shaft lock
button to lock shaft and TIGHTEN BLADE
STUD CLOCKWISE 1/8 TURN (45°) WITH
THE WRENCH PROVIDED.
See Fig. 2 for complete blade assembly order.
Do not use wrenches with longer handles,
since it may lead to over tightening of the
blade stud.
Only use 5-3/8” metal
cutting blades recom-
mended in this manual. Do not use abrasive
wheels. Using blades not recommended in this
manual can result in a hazardous situation.
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.
