WARNING:

MISUSE or failure to follow the safety rules stated in

this instruction manual may cause serious personal

injury.

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 reposi-

tion as shown in the figure which allows you to make five-

way adjustment. To secure the shoe, push the shoe but-

ton 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 & 5)

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.
