SWITCHING ON AND OFF
- To switch the tool on, depress the variable speed switch (1). The tool speed depends
on how far you depress the switch.
- For continuous operation, press the lock-on button (3) and release the variable speed
switch. This option is available only at full speed.
- To switch the tool off, release the variable speed switch.
To switch the tool off when in continuous operation, press
the variable speed switch once more and release it.
SPEED CONTROL DIAL
By rotating the speed control dial (2), the maximum
speed- or strokes-per-minute at which the blade will cut is
adjusted. Rotating the dial in the direction shown in figure
E will increase speed. To decrease speed, rotate dial in
opposite direction.
CUTTING ACTION – ORBITAL OR STRAIGHT (FIGURE F)
CAUTION:
Check that the tool is not locked on before connecting it to a power supply.
If the trigger switch is locked on when the tool is connected to the power supply, it will start
immediately. Damage to your tool or personal injury may result.
This jig saw is equipped with four cutting actions, three orbital and one straight. Orbital
action has a more aggressive blade motion and is designed for cutting in soft materials
like wood or plastic. Orbital action provides a faster cut, but with a less smooth cut across
the material. In orbital action, the blade moves forward
during the cutting stroke in addition to the up and down
motion.
NOTE: Metal or hardwoods should never be cut in orbital
action.
To adjust the cutting action:
- Move the cutting action lever (8) between the four
cutting positions: 0, 1, 2, and 3.
- Position 0 is straight cutting.
- Positions 1, 2, and 3 are orbital cutting.
- The aggressiveness of the cut increases as the lever
is adjusted from one to three, with three being the most
aggressive cut.
Hints for optimum use
Sawing laminates
As the saw blade cuts on the upward stroke, splintering may occur on the surface
closest to the shoe plate.
- Use a fine-tooth saw blade.
- Saw from the back surface of the workpiece.
- To minimize splintering, clamp a piece of scrap wood or hardboard to both sides of the
workpiece and saw through this sandwich.
Sawing metal
- Be aware that sawing metal takes much more time than sawing wood.
- Use a saw blade suitable for sawing metal.
- When cutting thin metal, clamp a piece of scrap wood to the back surface of the
workpiece and cut through this sandwich.
- Spread a film of oil along the intended line of cut for
easier operation and longer blade life. For cutting
aluminum, kerosene is preferred.
RIP / CIRCLE CUTTING (FIGURE G, H)
Ripping and circle cutting without a pencil line are easily
done with the rip fence / circle guide (not included -
available at extra cost).
Using the screw supplied with the accessory guide,
position as shown in figure G and thread the screw into
the shoe to clamp the fence securely.
When ripping, position as shown in figure G and slide
the rip fence under the screw from either side of the saw.
