Vacuum port switch (Fig. F)
During normal use without the vacuum connected, the
vacuum port switch (11) must be slid toward the rear of the
tool . This will allow the internal motor fan to continuously
blow the sawdust away from the cutting mark. When the
vacuum is connected, the vacuum port switch must be
slid toward the front of the tool. This positions the internal
baffle to divert the sawdust through the vacuum port so it
can be evacuated by the workshop vacuum.
OPERATION
Warning! Never use the tool when the saw shoe plate is
loose or removed.
General cutting
Warning! Keep hands and fingers away from the space
between the motor housing and the blade clamp. Do not
reach underneath workpiece while the saw is running.
Rest the front of the sole plate on the workpiece and align
the cutting edge of the blade with the cutting line on your
workpiece (Fig. G). Make sure the power cord is out of
your way and not in the path the blade will follow. Start
your saw and move it toward the workpiece. Apply enough
downward pressure to keep the saw steady and only
enough forward pressure to keep the blade cutting freely.
Warning! Do not force the saw. Forcing the saw may
overheat the motor and break saw blades.
Bevel cutting
Bevel cutting angles may be adjusted from zero to 45°
either left or right. To adjust the bevel angle:
1. Loosen both sole plate pivot screws (12) until the sole
plate (13) can be rotated
Note: Use the 3 mm hex key supplied.
2. Bevel angles (15) are marked on a scale located on
the side of the sole plate
3. Slide the sole plate back. Align the edge of the motor
housing (16) with the desired angle mark (15) on the
side of the base, then slide the sole plate forward to
engage the notches (14) into the motor housing pin.
Note: Angle marks on the sides of the jigsaw base
are for reference only. Operator should use a
protractor to verify angles.
4. Once the desired bevel angle is obtained, lock the
sole plate by tightening the sole plate pivot screws.
5. Make a test cut in a scrap piece of material and
measure the bevel angle. Adjust bevel angle if necessary.
HINTS FOR OPTIMUM USE
Sawing laminates
When cutting laminates, splintering may occur which can
damage the presentation surface. The most common saw
blades cut on the upward stroke, therefore if the shoe plate
(Fig. H).
(Fig. I).
is sitting on the presentation surface either use a saw
blade that cuts on the downward stroke or:
f Use a fine-tooth saw blade.
f Saw from the back surface of the workpiece.
f To minimise splintering, clamp a piece of scrap wood
or hardboard to both sides of the workpiece and saw
through this sandwich.
Sawing metal
Warning! Do not use a vacuum when cutting metal.
Metal filings will be hot and may cause fire. Be aware that
sawing metal takes much more time than sawing wood.
f Use a saw blade suitable for sawing metal.
f When cutting thin sheet metal, clamp a piece of scrap
wood to the back surface of the workpiece and cut
through this sandwich.
f Spread a film of oil along the intended line of cut.
Plunge cutting
Warning! To avoid loss of control, broken blades or
damage to the workpiece, always use extreme caution
when making plunge cuts. It is not recommended to plunge
cut any material other than wood. Wherever possible, drill
a 3/8" (8 mm) or bigger pilot hole in the area to be cut out
and start cutting with the blade in the pilot hole. This will
avoid the need to plunge cut.
Note: Use only blades with 7 teeth per inch for plunge cutting.
1. To plunge cut an inside hole, clearly mark the cutting
line on the workpiece.
2. Set the bevel angle at 0° then lock the sole plate.
3. Tilt the saw forward so it rests on the front edge of the
sole plate and in a position so the blade will NOT touch
the workpiece when the switch is turned ON (Fig. J).
Note: Make sure the saw blade is inside the area to
be cut.
4. Start the saw and slowly lower the blade onto the
workpiece while making sure the front of the sole plate
remains in contact with the workpiece. Allow the blade
to cut through the wood.
5. Continue lowering the blade into the workpiece until the
sole plate rests flat on the workpiece. Continue sawing
toward the cutting line and complete the cut as required.
Metal cutting
Many types of metal can be cut with your jigsaw. When
cutting any kind of material, be careful not to twist or
bend the blades. Do not force the blade. If the blade
chatters or vibrates excessively, use a finer tooth blade.
If the blade heats excessively, reduce speed of cutting.
If the blade teeth become clogged when cutting soft
metals such as aluminum, use a coarser blade with fewer
teeth per inch. Clamp all work firmly and saw as close as
