Husqvarna K 770 Manuel D'utilisation page 18

Special care should be taken when cutting in pipes. If
the pipe is not properly supported and the cut kept open
through out the cutting, the blade might be pinched. Be
especially alert when cutting a pipe with a belled end or
a pipe in a trench that, if not properly supported, may
sag and pinch the blade.
If the pipe is allowed to sag and close the cut, the blade
will be pinched in the kick back zone and a severe kick
back might develop. If the pipe is properly supported the
end of the pipe will move downward, the cut will open
and no pinching will occur.
1. Secure the pipe so it does not move or roll during
cutting.
2. Cut section "I" of the pipe.
III
3. Ensure that the cut opens to avoid pinching.
4. Move to side II and cut from section I to bottom of
the pipe.
5. Move to side III and cut the remaining part of the
pipe ending at the bottom.
To prevent a kickback
WARNING: Avoid situations where there is a
risk of kickback. Take care when using your

power cutter and make sure that the blade is
never pinched in the kickback zone.
WARNING: Be careful when you put the
blade in an existing cut.
WARNING: Make sure that the work piece
cannot move during a cutting operation.
WARNING: Only you and proper working
technique can eliminate kickback and its
dangers.
• Always support the work of piece so that the cut can
keep open when cutting through. When the cut is
open there is no kickback. If the cut is closed and
pinches the blade, there is a risk of kickback.
Basic working techniques
WARNING: Do not pull the product to one
side. This can prevent the free movement of
the cutting blade. The cutting blade can
break and cause injury to the operator or
bystanders.
WARNING: Do not grind with the side of the
cutting blade. The cutting blade can break
and cause injury to the operator or
bystanders. Only use the cutting edge.
WARNING: Make sure that the cutting blade
is installed correctly and does not show
signs of damage.
WARNING: Before cutting in an existing cut
made by a different blade, make a sure that
the slot is not thinner than your blade as that
can result in binding in the cutting slot and a
kickback.
WARNING: Cutting metal generates sparks
that can cause fire. Do not use the product
near flammable material or gases.
