Kickback
The word kickback is used to describe a sudden reaction that causes the chain saw to be
kicked uncontrollable into the direction of the user or away from the user depending on the
direction of rotation. Kickback is caused by blocking of the chain. This uncontrollable
movement can cause damages on material and personal injury. A kickback is the result of an
incorrect or improper use of the chain saw.
a)
Always hold the machine in a firm grip with both hands. Bring your body and
arms in a position in which you can control the rebound forces. The operator can
control the rebound and reaction forces by appropriate precautions.
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.

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.
