Genesis Advanced Technologies GJS450 To remove the blade, Speed Adjustment Dial

English

To remove the blade:

1.Position the Chip Shield up to allow access to the Blade Collet.

2.Open the Blade Collet by rotating the (Spring Loaded) Collet Lever clockwise.

3.Pull the blade out from the Blade Collet.

4.Release the Collet Lever.

CAUTION: Always cut with the Chip Shield down and hold the base flush with the workpiece. Failure to do so may cause blade breakage, resulting in a serious injury.

SPEED ADJUSTMENT DIAL

Your jig saw is equipped with a speed adjusting dial located on the upper, forward portion of the saw's handle. Tool speed can be infinitely adjusted between 500 and 3,000 strokes per minute by rotating the adjusting dial. Speed indicators appear on the dial as the numbers 1 through 6: 1 is the slowest saw speed and number 6 represents the highest speed. Therefore, higher speed when the dial is rotated towards number 6 speed increases; lower speed is obtained when the dial is rotated in the direction of number 1. The speed adjusting dial can be operated while the saw is running or when the saw is not operating. The operator has the ability to preset the saw's speed by rotating the dial to the desired setting and then fully depressing the switch trigger, turning the saw on for use. Please note: regardless of pressure applied on the trigger, the tool will not operate any faster than the maximum speed setting selected. Be aware that when the jigsaw is operated at low speed the motor temperature will begin to rise due to the slower speed of the internal cooling fan. In such cases, it is necessary to occasionally run the tool at full speed for a few minutes to aid internal cooling to keep the motor operating at high efficiency.

The jig saw cutting speed (or stroke rate) required depends on the material being cut, the type of blade being used, and the feed rate used by the operator. The best speed for a particular application is largely based on operator experience or experimentation. However, as a general rule, slower speeds are for denser materials and faster speeds for soft materials. Saw blade life is also largely determined by the motor speed and the type of material being cut. The following chart is intended as a guideline only; test cuts in scrap should be performed first to determine the best speed setting.

The speed adjusting dial can be turned only as far as 6 and back to 1. Do not force it past 6 or 1, doing so may cause the speed adjusting function to no longer function properly.

SELECTING THE ORBITAL CUTTING ACTION

This jigsaw can be operated in the conventional straight line (up and down) mode or with an “orbital” cutting action. During orbital cutting, the blade is thrust forward on the upward (cutting) stroke, greatly increasing cutting speed. During the down stroke, the blade is cleared of accumulated debris, enhancing cutting efficiency and extending blade life by causing the blade to run cooler. The orbital action adjustment switch is located on the lower left hand portion of the motor housing near the chip deflector. The motor housing is marked: 0, I, II, III. The “0” designates the straight-line mode.

“I” through “III” designate increasing levels of orbital action. Just as with blade speed, selecting the proper orbital action is largely a matter of operator experience and experimentation on scrap. The chart shown below is intended as a guideline only.
