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.
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.

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

6. Adjusting the base
(1) Lift the front cover up as illustrated in Fig. 11 .
Fig. 11
(2) If a base setting screw is loosened with an attached
hexagonal bar wrench, you can adjust a base installing
position. (

(3) After adjusting the base installing position, tighten
the base setting screw with the attached hexagonal
bar wrench completely.
7. Adjusting the blade reciprocating speed
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. 14 )
Fig. 14
(1) If you pull the trigger further in, the speed of the blade
accelerates. Begin cutting at a low speed to ensure
the accuracy of your target cut position. Once you’ve
obtained a sufficient cutting depth, increase the
cutting speed.
(2) On the dial scale, “5” is the maximum speed and “1”
the minimum. The high speed is generally suitable
for soft materials such as wood, and the low speed is
suitable for hard materials such as metal. We
recommend that you use the following as a rough
guide in selecting the suitable speed for the materials
you are cutting.
