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 bolt is not sufficiently tightened, the bolt can
get loose, the blade can come off, and the safety cover can get damaged, resulting in
injuries.
Also, check that the bolts are properly tightened before plugging the power plug into
the receptacle.
* If the bolts are attached or detached using tools other than the 10mm box wrench
(standard accessory), excessive or improperly tightening occurs, resulting in injury.
1. Mounting the saw blade (Fig. 51-a, Fig. 51-b and Fig. 51-c)
(1) Use the accessory 10mm box wrench to loosen the 6mm bolt fastening the spindle cover and then

box wrench (standard accessory) while applying pressure on the spindle lock.
The saw blade spindle is locked when the spindle lock is pressed inward.

When mounting the saw blade, confirm that the rotation indicator mark on the saw
blade and the rotation direction of the gear case(see Fig. 1) are properly matched.
* A dust guide is installed inside behind the gear case.
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 bolt so it does not come loose during operation.
Confirm the bolt has been properly tightened before the power tool is started.
Never attempt to install saw blades larger than 10" (255mm) in diameter.
Always install saw blades that are 10" (255mm) in diameter or less.
