Pipe cutting
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 in the
kickback zone and cause a severe kickback. 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.
Before starting the cut the pipe must be secure so it does
not move or roll during cutting.
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.
Proper sequence cutting a pipe
1
First cut section I.
2
Move to side II and cut from section I to bottom of the
pipe.
3
Move to side III and cut the remaining part of the pipe
ending at the bottom.
How to aviod kickback
Avoiding kickback is simple.
•
The work piece must always be supported so that the
cut stays open when cutting through. When the cut
opens there is no kickback. If the cut closes and
pinches the blade there is always a risk of kickback.
•
Take care when inserting the blade in an existing cut.
•
Be alert to movement of the work piece or anything
else that can occur, which could cause the cut to close
and pinch the blade.
Transport and storage
•
Secure the equipment during transportation in order
to avoid transport damage and accidents.
•
Do not store or transport the power cutter with the
cutting blade fitted.
•
For transport and storage of cutting blades, see the
section "Cutting blades".
•
For transport and storage of fuel, see the section
"Fuel handling".
•
Store the equipment in a lockable area so that it is out
of reach of children and unauthorized persons.
