By changing the position of the guide and
using the same straight edge as a
guide, it is possible to quickly and easily
make parallel cuts in the workpiece.
NOTE: When adjusting the cutting angle,
you can move the parallel guide lock
screw to the left or right.
DUST EXTRACTION
To improve dust extraction from the
working area, insert the dust extraction
adaptor (4) to the rear of the shoe plate,
and then connect to a dust extraction
system or a suitable vacuum cleaner.
(Fig.5)
WARNING: Do not use a dust extraction
system or a vacuum cleaner when
cutting metal. Sparks may ignite residual
wood dust.
VACUUM AND BLOWER
Slide the vacuum /blower selector (21)
back to blow dust and chips away from
the cutting area
Slide the selector forward while
connected to a dust extraction system
or household vacuum. (Fig.6)
ORBIT ADJUSTMENT
This jigsaw has orbital action whereby the blade roller guide (7) moves back
and forth to make the blade swing slightly as it cuts.
Orbit action increases the speed of cut but may result in a rougher finish to the
cut in some materials.
Set the orbit control lever (8) to one of the four settings according to the degree
of orbit action required. (Fig. 7)
0- No orbital action
Plug into the power source and run the saw under no-load to check that it runs
smoothly before using it to cut any materials.
CAUTION! The blade roller guide (7) supports the blade when cutting and
must at all times rest against the back edge of the blade. It should rotate freely.
ADJUSTING THE SHOE FOR ANGULAR CUTTING
CAUTION!
Always ensure that the jigsaw is switched off and the plug is re-
moved from the power source before making any adjustments.
Loosen the hex screw located on the underside of the tool using the hex key
(12). (Fig.2)
Move the shoe plate (5) backward so that
the teeth on the plate no longer engage
with the retaining teeth and the shoe can
be tilted to the left and right.
If the required angle is 15°, 30° or 45° to
the left or right or 0°, push the shoe plate
forward so that the teeth on the plate
mesh with the retaining teeth (Fig. 3)
Retighten the hex screw.
The angle selected can be read on the
cutting angle guide (9) on the shoe plate
(5).
For accurate work it may be necessary
to make a trial cut, measure the work
and reset the angle with the shoe plate
moved a little towards the rear so that
the metal prongs do not mesh with the
retaining teeth.
Repeat the trial cut and reset the angle setting until the correct setting
is achieved.
PARALLEL GUIDE
The parallel guide (15) fits into the shoe plate (5) and is locked in place by the
parallel guide lock screw (16). (Fig.4)
Use the parallel guide to guide the jigsaw along a straight line, which can be an
edge of a workpiece or a piece of straight timber clamped to the workpiece.
