Switch action
► Fig.4: 1. Switch trigger 2. Lock button
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: 1. Adjusting dial
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.
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 the 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 tighten-
ing 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
insulation 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 positon
► Fig.6: 1. Blade clamp sleeve 2. Released position
3. Fixed position
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp lever 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: 1. Blade
NOTE:
• If you do not insert the saw blade deep enough,
the saw blade may be ejected unexpectedly
during operation. This can be extremely
dangerous.
If the lever is positioned inside the tool, switch on the
tool just a second to let the blade out as shown in the
figure.
Switch off and unplug the tool from the mains.
To remove the saw blade, rotate the blade clamp
lever in the direction of the arrow fully. The saw blade
is removed and the blade clamp lever is fixed at the
released position
► Fig.8: 1. Blade clamp lever
NOTE:
• Keep hands and fingers away from the lever
during the switching operation. Failure to do so
may cause personal injuries.
• If you remove the saw blade without rotating
the blade clamp lever fully, the lever may not be
locked in the released position
rotate the blade clamp lever fully again, then
make sure that the blade clamp lever locked at
the released position
