(counterclockwise).
F.
Remove the outer washer
30
and the
saw blade
29
from the blade shaft

ATTACHING THE BLADE
G.
Make sure the replacement saw blade
29
and washers
28
and
30
are clean. Place
the saw blade
29
on to the inner washer
28
. Make sure the saw blade teeth and
arrow
29a
on the blade point in the
same direction as the arrow
15a
on the
blade guard

.
H.
Mount the outer washer
30
and screw
the blade stud
25
into the blade shaft
27
turning
in
rotation

J.
Pivot the depth lock lever

toward the
front. When doing this, the saw retracts
back to the starting position.
VARI-TORQUE CLUTCH
This clutching action is provided by the
friction of the outer washer
30
against the
blade
29
and permits the blade shaft
27
to
turn when the blade encounters excessive
resistance. When the blade stud
25
is
properly tightened (as described in step I
of “Attaching The Blade”), the blade will

to kickback.

slippage occurs, tighten the blade stud a
fraction of a turn more (less than 1/8 turn).
