3. For accurate cut it is nece ssary to make a trial cut, measure the work and reset the angle until the correct
setting is achieved.
Cutting - Orbital or Straight
ig. 7
This jig saw is equipped with four cutting actions, one straight and three orbital. Orbital action has a more
aggressive blade motion and is designed for cutting in soft materials like wood or plastic. Orbital action provides
faster cut, but with a rougher 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, moves the orbital switch knob (8) between the four cutting positions: 0 , 1 , 2 , and 3 .
Position 0 is the straight cutting. Positions 1 , 2 and 3 are orbital cutting. The aggressiveness of the cut increase as
the knob is moved from one to three, with three being the most aggressive cut. ( See Fig. 7 )
OPERATION
Never use a blade unsuitable for the task and item to be cut.
Hold the saw in front of you with a firm grip on the handle.
Ensure that the saw blade is not touching anything and that the power cable is not in the way when starting the
saw.
Make sure that the item is clamped tight, and that the saw line is clearly marked.
Connect the vacuum extractor nozzle to an extractor system where possible.
Start the saw. Place the soleplate on the item, and let the saw blade touch the saw line.
Saw, but do not place more pressure on the blade than is necessary. Avoid lateral pressure on the blade.
Specia l notes on jig sawing
Place the soleplate on the item so the saw blade is vertical and correctly positioned in relation to the saw line
without touching it.
Start the saw and tilt it carefully while supporting it using the soleplate until the blade touches the item at the
saw line.
Let the blade work through the item, continuing to tip the saw downwards until the sole is flush to the item and
the blade is perpendicular to it. If necessary, drill a hole of suitable diameter in the item for use as starting point.
Sawing wood
Check that the item does not contain nails or other metal objects. Always wear a mask.
Sawing metal
We recommend lubricating the material and saw blade with cutting oil to protect the tool and avoid overheating.
Support the item with wooden blocks on either side.
Sawing plastic
Make a test cut first to check if the material can tolerate the heat generated by sawing.
Important!
Check all screws on the saw regularly, particularly those that hold the blade. Tighten if required. Check regularly
that the carbon brushes are in a good condition. If the carbon brushes are worn, they should be replaced.
