Assembly
Warning! Before attempting any of the following
operations, make sure that the tool is switched off
and unplugged and that the saw blade has stopped.
Used saw blades may be hot.
Fitting the saw blade (fig. A)
Hold the saw blade (7) as shown, with the teeth
u
facing forward.
Push the locking lever (3) away from the shoe plate (4).
u
Insert the shank of the saw blade into the blade holder (8)
u
as far as it will go.
Adjust the saw blade support roller (17) as
u
described above.
Release the locking lever (3).
u
Connecting a vacuum cleaner to the tool (fig. B)
Slide the vacuum nozzle (9) into the dust extration
u
outlet (5).
Use
@
Adjusting the shoe plate for bevel cuts (fig. C)
Warning! Never use the tool when the saw shoe
plate is loose or removed.
The shoe plate (4) can be set to a left or right bevel angle
of 45°.
Loosen the screws (10). Some models have one screw.
u
Pull the shoe (4) forward, rotate the shoe to the left or
u
right and push it back into the 45° location.
Push the shoe (4) back, rotate to the right and pull it back
u
into the 45° location.
Tighten the screw.
u
To reset the shoe plate (4) for 90° cuts:
Loosen the screw (10).
u
Pull the shoe (4) forward, rotate to the centre and push it
u
back into the 0° location.
Tighten the screw.
u
Variable speed control
Use a high speed for wood, medium speed for aluminium
u
and PVC and low speed for metals other than aluminium.
Switching on and off
To switch the tool on, press the variable speed switch. The
u
speed depends on how far you depress the switch.
For continuous operation, press the lock-on button (2) and
u
press the variable speed switch. This option is available
only at full speed.
To switch the tool off, release the variable speed switch.
u
To switch the tool off, when in continuous operation, press
the variable speed switch once more and release it.
How to Use the Sightline® Feature (fig. D)
Use a pencil to mark the cutting line.
u
Position the jig saw over the line (11).
u
Viewing from directly above the jig saw, the line of cut can be
followed easily.
(original instructions)
Cutting mode
Pendulum stroke or action provides a more aggressive blade
motion and is designed for cutting soft materials such as wood
or plastic. It provides a faster cut, but with a less smooth cut
across the material. Your jig saw has a Pendulum Stroke dial.
Use of this dial is explained in the next section.
Note: Never use pendulum action to cut metal.
Pendulum Stroke dial (fig. E)
This unit has four cutting modes with increasing amounts of
pendulum action:
Position 0: metal and aluminium and sheet metal (no
u
pendulum action).
Position 1: for laminates, hard wood, work tops.
u
Position 2: for plywood and PVC/Plastics.
u
Position 3: for soft wood and fast cutting.
u
To adjust the pendulum action:
Rotate the Pendulum Stroke dial (6) to the
u
required position.
Sawing
Hold the tool firmly with both hands while cutting.
The shoe plate (4) should be held firmly against the material
being cut. This will help prevent the saw from jumping, reduce
vibration and minimise blade breakage.
Let the blade run freely for a few seconds before starting
u
the cut.
Apply only a gentle pressure to the tool while performing
u
the cut.
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 is sitting on the presentation surface
either use a saw blade that cuts on the downward stroke or:
Use a fine-tooth saw blade.
u
Saw from the back surface of the workpiece.
u
To minimise splintering, clamp a piece of scrap wood or
u
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.
Use a saw blade suitable for sawing metal.
u
When cutting thin sheet metal, clamp a piece of scrap
u
wood to the back surface of the workpiece and cut through
this sandwich.
Spread a film of oil along the intended line of cut.
u
Rip Fence
Ripping and circle cutting without a pencil line are easily done
with a rip fence and circle guide (available as an optional extra
- part number X43005-XJ).
