The plunge saw blades are ideal for making
precise cuts in tight areas, close to edges or
flush to a surface. Set the tool to a medium
speed (3) for greater control when making the
initial plunge. After making the initial cut, the
speed can be increased for faster cutting.
When flush cutting, do not force the tool.
A strong vibration during the plunge cut is
an indicator that you are applying too much
pressure – let the speed of the tool do the work.
GROUT REMOVAL
Before starting, measure the grout line width
to pick the appropriate blade. Set the tool to a
medium to high speed (3 – 5). To remove the
grout, use a back-and-forth motion, making
several passes along the grout line. Do your
best to keep the grout blade aligned with the
grout line and do not apply too much side
pressure on the grout blade during the process.
Use the carbide grit line on the blade as an
indicator to monitor the plunge depth. Do not
plunge beyond the carbide grit line to avoid
damage to the backer board.
CUTTING
Set the tool to a low to medium speed (1 – 3).
Turn the tool on and place the scraper on the
area where material is to be removed. Begin
with light pressure. Excessive pressure can
damage the background surface.
After turning the tool on, allow it to reach its full
speed before contacting the workpiece with the
tool and remove it from the workpiece before
switching the tool off.
Sand with a continuous motion and light
pressure. Do not apply excessive pressure –
let the speed of the tool do the work. Work
with the complete surface of the sanding pad,
not only with the tip. The sanding pad should
occasionally be rotated to distribute the wear on
the sanding sheet and backing pad surface.
