FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the shoe (Fig. 1 & 2)
When the blade loses its cutting efficiency in one place
along its cutting edge, reposition the shoe to utilize a
sharp, unused portion of its cutting edge. This will help to
lengthen the life of the blade. To reposition the shoe, push
the shoe button in the "A" direction with a click and
reposition as shown in the figure which allows you to
make five-way adjustment. To secure the shoe, push the
shoe button in the "B" direction with a click.
Selecting the cutting action (Fig. 3)
This tool can be operated with an orbital or a straight line
cutting action. The orbital cutting action thrusts the blade
forward on the cutting stroke and greatly increases cutting
speed.
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.

Switch action (Fig. 4)
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
operation, pull the switch trigger and then push in the lock
button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Speed adjusting dial (For JR3070CT)
(Fig. 5)
The strokes per minute can be adjusted just by turning the
adjusting dial. This can be done even while the tool is
running. 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
workpiece to be cut. However, the appropriate speed may
differ 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.

NOTE:
• If the tool is operated continuously at low speeds for a
long period of time, the operation life of the motor will
be reduced.
• 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.
