ATTACHING THE BLADE
Disconnect the plug from
W RNING
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting the
tool accidentally.
1. HD5687, HD5687M: Press the lock button
and turn wrench until lock button engages. Saw
shaft is now locked. Continue to depress button,
turn wrench counter-clockwise and remove
BLADE STUD and OUTER WASHER (Fig. 2).
5 5 8 7 : 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, strike the
wrench counter-clockwise to jar BLADE STUD
loose (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 (5587: To lock shaft
hold the saw securely by the upper guard with
blade teeth imbedded in scrap wood).
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.
