Operation; Metal Cutting - Dexter power NC750JS Manual De Uso

Pendulum lever
The pendulum lever has four positions. The first position selects normal cutting without pendulum action. The positions (1, 2 and3) cause the blade
to swing slightly backwards and forwards as it cuts. This pendulum action increases the efficiency of cutting, set the pendulum lever to one of the
three settings (1, 2 or 3) according to degree of pendulum action required.
Experiment on a piece of scrap material to determine the optimum pendulum action setting for the material of the work piece.
Recommendations (non-committal)
- No pendulum action for: cutting sheet metal, plastic sheets; very fine cutting edges
- Low pendulum action for: cutting hard wood, plastics; fine cutting edges on wood
- Max. Pendulum action for: cutting wood; if no fine cutting edges required
Turn on the laser
WARNING: Before proceeding to use the laser line system, ensure that the
Additional Safety Rules for Laser Lights section is read and fully understood.
Push the laser on/off switch down to turn on the laser. Push the laser on/off switch again to turn off the laser.
Always ensure the laser beam is aimed at a sturdy workpiece without reflective surfaces. i.e. wood or rough coated surfaces are acceptable. Bright
shiny reflective sheet steel or the like is not suitable for laser use as the reflective surface could direct the beam back to the operator.
General cutting
WARNING: Before cutting, secure and support the workpiece to a stable platform by using
clamps or another practical way.
Ensure that the blade is the correct type for the application and that the length extends through the workpiece on the upstroke of the cut.
1. Determine how the jigsaw is best configured for the job and make the required adjustment.
2. Switch on the jig saw and allow the blade to reach maximum speed.
3. Slowly guide the jig saw forward, building up speed as you go, keeping the shoe plate at against the workpiece.
NOTE: Do not force the jig saw. Use only enough pressure to keep the blade cutting. Do not
force the cutting, allow the blade and the saw to do the work.
NOTE: When cut 85mm thick wood, the length of the blade should be at least 150mm
long.

Metal cutting

1. When cutting metal ALWAYS clamp down the metal workpiece.
2. Be extremely careful to move the saw very slowly as you cut. Use slower speeds. DO NOT twist, bend or force the blade.
3. When cutting metals, suitable cooling/cutting oil must be used. Squirt the lubricant onto the blade or workpiece at regular intervals during
cutting in order to reduce wear on the blade.
