b)
Never get your hand near the rotating saw blade. The saw blade can touch your
hand during a kickback.
c)
When sawing, always stand parallel to the saw blade. Do never stand directly
behind the blade as the saw will move in the plane of the blade in case of a kickback.
Never use the kickback area of the ring saw for cutting.
d)
Never use the kickback area (upper quadrant) of the saw blade for cutting. You
can avoid a kickback when you cut with the lower quadrant of the saw blade.
e)
Work carefully in the area of sharp edges, corners, etc. Avoid the swa blade
beeing kicked back from the work piece and beeing blocked. The rotating saw
blade tends to be blocked at corners and sharp edges or if it is rebounded. This
causes a loss of control or kickback.
f)
Avoid blocking of the blade by too high contact pressure. Avoid too deep cuts.
Overstressing of the saw blade increases wear and the liability for blocking and
therefore the possibility of a kickback or break of the abrasive body.
g)
If the saw blade is blocked or if you stop work shut off the machine and keep it
still until the saw blade has stopped completely. Never try to remove the running
saw blade out of the cut as long as the saw blade is still turning, otherwise this
may cause a kickback. Detect and eliminate the reasons for blocking.
h)
Do not switch on the ring saw as long as it is located in the workpiece. Only
begin to move the saw blade in the cut when the blade has reached full speed.
Otherwise the blade can be blocked, rebounds from the workpiece or causes a
kickback.
i)
Support slabs or big workpieces in order to reduce the risc of a kickback as a
result of a jammed saw blade. Big work pieces can bend under their own weight.
The work piece has to be supported at both sides of the saw blade both near the cut
and at the edge.
j)
Be very careful with "bag cuts" in existing walls or other non-visible areas. The
saw blade can cause a kickback when hitting a gas or water pipe, electric line or
another object.

Your TR40 is a full electrical ring saw which is only to be used for cutting masonry, stone and
concrete in industrial usage by trained personnel.
Water is absolutely required for cooling motor and saw blade. The ring saw blade always has to be
cooled with water in order to avoid overheating.
The ring saw blade consists of a metal ring that is equipped with segments of a sintered mixture of
diamond grains and metal powders.
The sawing process is introduced by dipping the saw blade into the material, which is to be cut. Move
the blade slowly forwards and backwards ober the work piece in order to execute the cut.
The machine may not be used for a different purpose or with a different tool.
