during bevel cutting.
SAW BLADE MOUNTING AND DISMOUNTING
WARNING
*To prevent an accident or personal injury, always turn
off the trigger switch and disconnect the power plug
from the receptacle before removing or installing a
saw blade.
If cutting work is done in a state where the 10 mm
bolt is not sufficiently tightened, the 10 mm bolt can
get loose, the blade can come off, and the lower guard
can get damaged, resulting in injuries.
Also, check that the 10 mm bolts are properly
tightened before plugging the power plug into the
receptacle.
* If the 10 mm bolts are attached or detached using tools
other than the 17 mm box wrench (standard
accessory), excessive or improperly tightening occurs,
resulting in injury.
1. Mounting the saw blade (Fig. 55-a, Fig. 55-b, Fig. 55-
c and Fig. 55-d)
(1) Use the Phillips screwdriver to loosen the 5 mm screw
fastening the spindle cover and then turn the spindle
cover.
(2) Press in spindle lock and loosen 10 mm bolt with 17
mm box wrench (standard accessory).
Since the 10 mm bolt is left-hand threaded, loosen by
turning it to the right as shown in Fig. 55-c.
NOTE
If the spindle lock cannot be easily pressed in to lock
the spindle, turn the 10 mm bolt with 17 mm box
wrench (standard accessory) while applying pressure
on the spindle lock.
The saw blade spindle is locked when the spindle lock
is pressed inward.
(3) Remove the bolt and washer (B)

WARNING
When mounting the saw blade, confirm that the
rotation indicator mark on the saw blade and the
rotation direction of the spindle cover (see Fig. 1) are
properly matched.
(5) Thoroughly clean washer (B) and the 10 mm bolt, and
install them onto the saw blade spindle.
(6) Press in the spindle lock and tighten the 10 mm bolt
by turning it to the left by 17 mm box wrench
(Standard accessories) as indicated in Fig. 55-c.
CAUTION
*A dust guide is installed inside behind the hinge.
When removing or installing the saw blade, do not
make contact with the dust guide. Contact may break
or chip saw blade tips.
* Confirm that the spindle lock has returned to the
retract position after installing or removing the saw
blade.
*Tighten the 10 mm bolt so it does not come loose
during operation.
Confirm the 10 mm bolt has been properly tightened
before the power tool is started.
2. Dismounting the saw blade
Dismount the saw blade by reversing the mounting
procedures described in paragraph 1 above.
The saw blade can easily be removed after lifting the
lower guard.
CAUTION
Never attempt to install saw blades larger than 305
