2. Dismounting the 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.
