7. Dismounting the blade
CAUTION
Never touch the saw blade immediately after use.
The blade is hot and can easily burn your skin.
(1) Turn off the switch and disconnect the plug from the
receptacle.
(2) After pivoting the lever, point the blade downward.
The blade fall out on its own. If the blade fails to fall
out, pull it out by hand.
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
when the lever is pivoted and the blade is pointed
downward. If the blade fails to fall out on its own, take
it out by using the procedures described 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. 5)

WARNING
To avoid injury and damage, do not operate the
saw without the base in place. The plunger may
strike against the workpiece and damage the
reciprocating mechanism.

This unit has a built-in electronic control circuit that
makes it possible to adjust the variable speed of the
saw blade either both by pulling a switching trigger or
turning a dial. (Fig. 9)
