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.
Scraping
Set the tool to 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.
Sanding
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 o.
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.
Using attachments
WARNING!
Detach the battery pack from the tool
before performing any assembly,
adjustments, or changing accessories. Such
preventive safety measures reduce the risk of
starting the tool accidentally.
Depth gauge (See gure N)
The depth gauge allows you to control the
depth of the plunge cuts. This is especially
helpful when plunge cutting an opening in
drywall where you don’t want to accidentally
damage objects or surfaces behind the drywall.
To use the depth gauge:
■
Insert it into the attachment collar and set
the distance “X” between the tip of the
plunge blade and the tip of the depth
gauge.
■
If the blade is installed at an angle, loosen
the collar locking bolt and rotate the collar
around the neck of the tool until the depth
gauge is parallel to the blade. Tighten the
collar locking bolt.
■
The bent tip of the depth gauge can be
positioned either above the blade or to
the side based on your preference and
situation.
■
Tighten the locking knob. This will be your
depth of cut.
Edge guide (See gure O, P)
The edge guide O-3 is used to make thru
cuts parallel to a straight edge or a piece
of plywood temporarily secured to the
workpiece with screws or clamps O-1. Make
sure that the clamps do not interfere with the
free movement of the tool throughout the
entire length of the cut.
To use the edge guide:
■
Insert it into the attachment collar and position
it at an angle to the blade (see gure O).
■
Loosen the collar locking bolt and rotate
the collar around the neck to make sure
that blade is fully engaged into the
workpiece throughout the complete
stroke (oscillation) of the blade. If either
edge of the blade travels outside of the
workpiece, the tool may jump causing
loss of control and damage to the
workpiece. Tighten the collar locking bolt
(see gure O).
■
Press the right edge of the edge guide
against the straight edge O-2 and start the
tool. Continue cutting along the straight
edge (see gure O).
The edge guide can also function as the
depth gauge when using a segment blade
P-1(not included with the tool).
■
With the segment blade installed, move
the edge guide do desired distance “X”
away from the tips of the segment blade
teeth (see gure P).
■
Tighten the locking knob (see gure P).
