Once the cut has been finished, lift the tool from the work surface before switching off. If a
lot of dust has been created, keep switched on for a few seconds extra to allow the dust to
clear from within the tool.
10 CUT-OUTS
Plunge cutting may not be possible in some hard materials.
Choose a suitable saw blade for hard materials and change to it. Set the depth of cut (See
“Setting the Cutting Depth” section), plug in the mains supply and then place the metal
base plate (18) onto the work surface. Ensure that the front indication mark on the base
plate aligns with the start line (See
“Line Following” section).
Switch on the tool and wait for a moment for the blade to run up to speed. Next, plunge
the blade into the material slowly and gently, but firmly. Then push the tool forwards along
the line to be cut. (Never draw the tool backwards)
Once the finish line has been reached, lift the tool from the work surface before switching
off. If a lot of dust has been created, keep switched on for a few seconds extra to allow the
dust to clear from within the tool.
Cutting out tips:
If the cut is to be covered, for example by a vent cover, the corners can be overlapped to
ensure that the waste material is completely detached.
If the cut out is to be seen, do not overlap the corners. In this circumstance, as the cutting
blade is circular, the waste material will not be fully detached. The corners will therefore,
require finishing with a knife. If the material is thin and the back surface unimportant, the
waste material can just be pushed out.
Where there is access to the back surface of the material to be cut, the cut out can be
marked out with an over cutting allowance. The cut is then made from the back surface to
ensure perfect corners on the front surface. A table of over cutting allowances is shown in
the specifications section.
11 CUTTING PARTICULARLY TOUGH OR ABRASIVE MATERIALS
Learn to use the tool by cutting wood before attempting to cut anything tougher. When cutting
tougher material, such as metals, more force is required to hold the work piece and clamping
may be required.
Never cut materials that produce toxic dust or fumes such as PTFE or asbestos.
11.1
Sheet metal:
Always set the depth adjustment to at least 1 mm deeper than the material thickness to
avoid the blade riding up over the surface. Scrap material is required underneath the work
surface.
Remove burrs and rust as these impede the feed across the material.
Thick beeswax (furniture polish) applied to the base plate of the tool makes metal cutting
easier.
Only suitable for cutting brass, copper, lead, aluminium or galvanised mild steel.
Every 2 minutes of metal cutting should be followed by a rest of at least 3 minutes.
11.2
Ceramic tiles, slates etc:
Only use a blade specifically designed for this purpose.
Always use with a suitable vacuum cleaner or dust extractor connected as the dust can be
hazardous to the operator and prevent the guard operating correctly.
11.3
Plasterboard:
The plunge saw is only recommended for making occasional cut outs in plasterboard and
always us it with a suitable vacuum cleaner or dust extractor connected. The dust can
prevent the guard operating correctly.
