PLUNGE CUTTING
WARNING: Plunge cutting is a technique that must only be
used on soft building materials such as plasterboard etc. It is
not a suitable procedure for use on harder materials, and must
never be employed on metallic materials.
Note: This technique should not be attempted by
inexperienced operatives.
Note: Only dedicated plunge cutting blades must be used
when attempting a plunge cut.
Note: To reduce the risk of blade kickback when plunge cutting.
It is recommended to drill a pilot hole and plunge cut into the
hole as a starting point, giving you extra control and stability.
To plunge cut:
• Complete any/all marking out of the cutting lines using
a pencil, marker pen, etc, on the workpiece before
commencing operations.
• Hold the machine at an angle to the workpiece with the
bottom edge of the workpiece contact plate resting firmly
against the workpiece. (Fig. 10).
Note: The blade must not be in contact with the workpiece at this
stage. The operator must also be satisfied that the blade will not
contact the workpiece immediately the machine is switched on.
• Set stroke rate to its maximum setting.
• Switch the machine on.
• Very slowly rotate the machine using the bottom edge of
the workpiece contact plate as a fulcrum. Allow the blade
to very gradually ingress into the workpiece.
• When the contact plate is lying flat against the workpiece
continue cutting as normal.
• Adjust the stroke rate for optimum cutting performance.
FLUSH CUTTING
Flush cutting is cutting very close to a surface such as a floor,
wall or ceiling etc. This technique allows the operator to cut
off unwanted protruding material such as redundant joists,
brackets pipes, etc, from a building.
WARNING: The operator should ensure that any redundant
architectural objects etc, are not 'live' and it is safe to cut
through them.
Note: Flush cutting is only possible when using highly flexible
bi-metal blades.
