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. 8)

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. 9, 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. 10 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. At
this time, make certain that there
exists no clearance between the
blade holder and the rubber cap,
and furthermore ensure that the
saw-blade-installed area can
function smoothly.

Do not use any saw blade with a
worn-out blade hole. Otherwise, the
saw blade can come off, resulting
in personal injury. (Fig. 11)
