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 bar. Do never stand directly behind the bar
as the saw will move in the plane of the bar in case of a kickback. Never use the kickback
area of the chain saw for cutting.
d) Never use the kickback area (upper quadrant) of the bar for cutting. You can avoid a
kickback when you cut with the lower quadrant of the bar.
e) Work carefully in the area of sharp edges, corners, etc. Avoid the chain 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.
e) Avoid blocking of the chain by too high contact pressure. Avoid too deep cuts.
Overstressing of the chain increases wear and the liability for blocking and therefore the
possibility of a kickback or break of the abrasive body.
f) If the chain is blocked or if you stop work shut off the machine and keep it still until
the chain has stopped completely. Never try to remove the running chain out of the
cut as long as the chain is still moving, otherwise this may cause a kickback. Detect
and eliminate the reasons for blocking.
g) Do not switch on the chain saw as long as it is located in the workpiece. Only begin
to move the chain in the cut when the chain has reached full speed. Otherwise the
chain can be blocked, rebounds from the workpiece or causes a kickback.
h) 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.
i) Be very careful with "bag cuts" in existing walls or other non-visible areas. The
chain can cause a kickback when hitting a gas or water pipe, electric line or another
objects.
3. T E C H N I C A L D E S C R I P T I O N
Your TK40 is a full electrical chain 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 the motor, bar and chain.
The diamond chain consists of different chain links (drive and cutting element). The cutting elements are
equipped with segments of a sintered mixture of diamond grains and metal powders.
The sawing process is initiated by dipping the bar with the diamond chain into the material to be
machined.
The machine may not be used for a different purpose or with a different tool.
