SAW BLADE MOUNTING AND DISMOUNTING
WARNING: To prevent an accident or personal injury, always turn off the trigger switch and discon-
nect the power plug from the receptacle before removing or installing a saw blade.
1. Mounting the saw blade (Fig. 24-a, Fig. 24-b and Fig. 25)
(1) Press in spindle lock and loosen bolt (A) with 17 mm box wrench.
Since the bolt (A) is left-hand threaded, loosen by turning it to the right as shown in Fig. 24-b.
NOTE: If the spindle lock cannot be easily pressed in to lock the saw blade spindle, turn the bolt
(A) with 17 mm box wrench while applying pressure on the spindle lock.
The saw blade spindle is locked when the spindle lock is pressed inward.
(2) Remove the bolt (A) and washer (B)
Fig. 24-a Fig. 24-b
(3) Lift the safety cover and mount the saw blade.
WARNING: When mounting the saw blade, confirm that the rotation indicator mark on the saw
blade and the rotation direction of the saw cover (see Fig. 1) are properly matched.
5. Cutting easily - deformed materials, such as aluminum sash
Materials such as aluminum sash can easily deform when tight-
ened too much in a vise assembly. This will cause inefficient cut-
ting and possible overload of the motor. When cutting such mate-
rials, use a wood plate to protect the workpiece as shown in
Fig. 21.
When cutting the aluminum materials, coat the saw blade with cut-
ting oil (non - combustible) to achieve smooth cutting and a fine
finish.
6. Cutting bent or uneven materials
To cut an uneven workpiece such as the one shown in Fig. 22, use a wood plate between vise (B) and the
workpiece as shown in Fig. 23.
