12. 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 materials, use a wood plate to protect the
workpiece as shown in Fig. 35.
When cutting aluminum materials, coat the saw blade with cutting
oil (non-combustible) to achieve smooth cutting and a fine finish.

13. How to use the dust bag (Standard accessory)
(1) When the dust bag has become full of sawdust, dust will be
blown out of the dust bag when the saw blade rotates.
Check the dust bag periodically and empty it before it becomes
full.
(2) During bevel and compound cutting, attach the dust bag at a
right angle to the base surface as shown in Fig. 36.
Fig. 36
CAUTION: Empty the dust bag frequently to prevent the duct and the safety cover from becom-
ing clogged.
Sawdust will accumulate more quickly than normal during bevel cutting.
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. 37-a and Fig. 37-b)
(1) Press in spindle lock and loosen bolt with 10mm box wrench.
Since the bolt is left-hand threaded, loosen by turning it to the right as shown in Fig. 37-b.
NOTE: If the spindle lock cannot be easily pressed in to lock the spindle, turn the bolt with 10mm
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 and washer (C)
