2. Dismounting the blade

Blade

(1)Turn on and off the switching trigger several times so that the lever can jump out of the front cover completely. Thereafter, turn off the switch and remove the battery. (Fig. 9)

CAUTION: Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident.

(2)After you have pushed the lever in the direction of the arrow mark shown in Fig. 10, turn the blade so it faces downward. The blade should fall out by itself. If the blade doesn’t fall out, pull it out by hand.

CAUTION: Never touch the saw blade immediately after use. The metal is hot and can easily burn your skin.

WHEN THE BLADE IS BROKEN

Even when the saw blade is broken and remains inside the small slit of the plunger, it should fall out if you push the lever in the direction of the arrow mark, and face the blade downward. If it doesn’t fall out itself, take it out using the procedures explained below.

(1)If a part of the broken saw blade is sticking out of the small slit of the plunger, pull out the protruding part and take the blade out.

(2)If the broken saw blade is hidden inside the small slit, hook the broken blade using a tip of another saw blade and take it out. (Fig. 15)

MAINTENANCE AND INSPECTION OF SAW BLADE MOUNT

(1)After use, blow away sawdust, earth, sand, moisture, etc., with air or brush them away with a brush, etc., to ensure that the blade mount can function smoothly.

(2)As shown in Fig. 16, carry out lubrication around the blade holder on a periodic basis by use of

cutting fluid, etc.

NOTE:

Continued use of the tool without cleaning and lubricating the area where the saw blade is installed can result in some slack movement of the lever due to accumulated sawdust and chips.
