c) Use the maximum cutting depth of the blade if
the wall is thinner than the maximum depth of the
blade. The cutting surface is decreased and the
pressure of the blade segments is increased.
Also do this when overcutting can not be done,
because the wedge remaining after sawing
becomes smaller. (A) = Overcutting distance, (B)
= Cutting surface.

d) When overcutting cannot be done, use a hand
cutter to cut the wedge. Speak to your local
Husqvarna dealer to get information about a
hand cutter.
6. Remove the blade from the sawing groove after
each cut.
CAUTION: Do not let the blade
rotate without pressure in the
sawing groove. This causes the
blade to become blunt.
7. Stop the motor and the water flow.
To cut concrete blocks
WARNING: Concrete blocks are very heavy
and can cause serious injury. Make sure
that the concrete block to be cut is attached
safely before operation.
1. Examine the dimensions of the concrete block to be
cut and make sure that it is safe to lift and remove.
2. Divide a large concrete block into smaller parts if it is
necessary. It is not necessary to move the rail or the
wall supports. You can cut on the 2 sides of the rail.

WARNING: Do not attach the wall
supports to the concrete block that
is to be cut.
Note: In the corners, the same holes can be
used for vertical and horizontal cuts.
4. Cut the concrete block in the sequence that follows.
The illustration shows the work procedure when you
divide a concrete block into 3 sections.

a) Do the horizontal cuts first. Start from the bottom
(A), (B), (C), (D).
b) Do the 2 vertical cuts (E).
5. Install wedge anchors after each cut. Install 2 wedge
anchors on the sawing side and 1 wedge anchor on
the other side of the concrete block.
6. When you make the last cut, attach the rail on a
stable wall. Use the included plastic wedges.
