Switch on the jigsaw and allow
the blade to reach maximumb speed.
Slowly guide the jigsaw forward, building up speed as you go, with one hand on the handle and the other on the scrolling knob, keeping the shoe plate flat against the workpiece (fig b).
Do not force the jigsaw. Use only enough pressure to keep the blade cutting. Do not force the cutting, allow the blade and the saw to do the work.
Pocket & curve cutting | c |
In order to start a cut from the centre of the workpiece, you can either drill a hole and insert the blade into the hole then start cutting, or plunge cut (fig c).
When using the hole method, |
| ||
use a 10mm or larger drill to |
| ||
| |||
ensure that there is sufficient | d | ||
clearance for the blade (fig d). | |||
| |||
To plunge cut, proceed as |
| ||
follows. |
| ||
Tilt the tool on the front edge |
| ||
of the shoe plate (18) with the |
| ||
point of the blade just above the |
| ||
workpiece (fig e). |
| ||
| |||
Switch on, wait for the blade to |
|
| |
| e | ||
reach maximum speed, hold the |
| ||
|
| ||
front edge of the shoe plate (18) |
|
| |
securely against the workpiece |
|
| |
and slowly lower the rear of the |
|
| |
saw so that the blade penetrates |
|
| |
the workpiece. |
|
| |
When the shoe plate is flush |
|
|
with the surface of the workpiece, proceed with cutting in the normal manner.
When cutting tight curves, reduce the speed of the saw.
WARNING. Do not move the saw forward
along its cut until the blade has completely entered the material and the shoe comes to rest on its surface.
Metal cutting
NOTES.
•When cutting metal ALWAYS clamp down the metal workpiece.
•Be extremely careful to move the saw very slowly as you cut. Use slower speeds (Position 1 on the speed controller).
DO NOT twist, bend or force the blade.
•When cutting metals, a 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.
•If the saw jumps or bounces as you cut, change to a blade with finer teeth.
•If the blade begins to clog when cutting soft metal, change to a blade with coarser teeth.
•For easier cutting, lubricate
the blade with a stick of cuttingf
wax (if available) or cutting oil when cutting steel (fig f).
•Thin metal should be sandwiched between two pieces of wood or tightly clamped on a single piece of wood (wood on top of the
metal). Draw the cut lines or design on the top piece of wood.
•When cutting aluminum extrusion or angle iron, clamp the work in a bench vice and saw close to the vice jaws.
•When sawing tubing with a diameter larger than the blade is deep, cut through the wall of the tubing and then insert the blade into the cut, rotating the tube as you saw.
