CAUTION
Be absolutely sure to keep the switch turned off and
the power cord unplugged to prevent any accident.
(2) After you have pushed the lever in the direction of
the arrow mark shown in Fig. 2, 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. 7)

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. 8, 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. Under the
circumstances, pull a rubber cap provided on the lever
in the direction of an arrow mark as shown in Fig. 9
and remove the rubber cap from the lever. Then, clean
up the inside of the blade holder with air and the like
and carry out sufficient lubrication. The rubber cap
can be fitted on if it is pressed firmly onto the lever.
