To change the cutting action, press the stopper and turn
the lever to the desired cutting action position. Then,
release the stopper to lock the lever. Refer to the table to
select the appropriate cutting action.
Note:
Orbital action means that the saw blade moves up and
down, and back and forth at the same time. This
increases the efficiency of cutting.

CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop. For continuous opera-
tion, pull the switch trigger and then push in the lock but-
ton.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Speed adjusting dial (For JR3070CT)
The strokes per minute can be adjusted just by turning the
adjusting dial. This can be done even while the tool is run-
ning. The dial is marked 1 (lowest speed) to 6 (full speed).
Turn the adjusting dial without positive stops between 1
and 6 according to your work.
Refer to the table to select the proper speed for the work-
piece to be cut. However, the appropriate speed may dif-
fer with the type or thickness of the workpiece. In general,
higher speeds will allow you to cut workpieces faster but
the service life of the blade will be reduced.

CAUTION:
• If the tool is operated continuously at low speeds for a
long time, the motor will get overloaded and heated up.
• The speed adjusting dial can be turned only as far as 6
and back to 1. Do not force it past 6 or 1, or the speed
adjusting function may no longer work.
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Electronic speed control for obtaining constant speed.
Possible to get fine finish, because the rotating speed is
kept constant even under load condition.
Soft start feature
Safety and soft start because of suppressed starting
shock.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing saw blade
CAUTION:
• Always clean out all chips or foreign matter adhering to
the blade, blade clamp and/or slider. Failure to do so
may cause insufficient tightening of the blade, resulting
in a serious injury.
To install the saw blade, always make sure that the blade
clamp lever is in released position
cover before inserting the saw blade. If the blade clamp
lever is in fixed position, rotate the blade clamp lever in
the direction of the arrow so that it can be locked at the
released position . (Fig. 6)
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp sleeve rotates and the saw blade is
fixed. Make sure that the saw blade cannot be extracted
even though you try to pull it out. (Fig. 7)
