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.
