Cutting
1. To help minimize blade deflection and thus provide
straighter cut lines, all wall sawing should be done
by using a step cutting procedure:
a. Start with a 24” diameter blade. (40” blade is
the largest blade recommended for the pilot
cut.)
b. The first pass should be 1 to 2 inches deep,
trailing the saw arm.
c. Subsequent passes, 3 to 4 inches deep.
d. Step up blade diameter in 6 inch increments
i.e. 24”, 30”, 36”.
e. Smaller diameter blades must cut sufficient
width for clearance for larger diameter blades.
2. On applications requiring a bottom horizontal cut,
this cut should be made first to prevent the
weight of the slab from pinching the saw blade. The
use of the proper metal straps will prevent the cut
portion from moving (Fig. B).
Mounting Track On Wall
1. Test drill several small holes 7/8 penetration on each
cut line, if steel reinforcement bar is present in the
wall to make sure that a bar does not lie in the plane
of the cut. If this occurs, the cut lines should be
moved to ensure that the blade does not cut the bars
longitudinally.
2. Set minimum 1/2” size anchors approximately 6
inches from the cut line (Fig. C). The distance
between anchors will depend on the track length
selected. Use 2 or 3 anchors for single length of
track. The choice of distance between anchors allows
the track to be moved longitudinally on the wall
without disturbing track mounting brackets.
3. Install the track mounting brackets on the anchors
with bolts so that the bracket edge is 3.6 inches
(91.44mm) from the cut line (Fig C). Do not tighten
down. (If preferred, install the brackets on the track
and attach the assembly to the anchors).
4. Level the brackets with the leveling screws so that
the tops of the brackets are parallel with the plane of
the wall.
5. Secure the track to the brackets with T-washers
and capscrews. Gear rack should be to the side of
the track nearest the cut line.
CAUTION
Make sure that the safety stops are at each
end of the track to prevent the saw from
running off the track.
6. Check to make sure the track is parallel to the wall
and the cut line. And that it does not have bends or
twists. Tighten the anchor bolts. When using two
interconnecting tracks, make sure the tracks are
aligned properly.
