Sample Applications - Stihl GS 461 Manual De Instrucciones

Sample applications

Use diamond abrasive
chain only with water.
Connect concrete cutter
to water supply network
(min. 22 PSI (1.5 bar)).
The water introduced is used to cool the
diamond abrasive chain and rinse
material from the bar groove and the rest
of the cutting attachment, and for
binding dust.
If the water pressure or water volume is
too low, this leads to significantly
increased wear and irreparable damage
to the cutting attachment – risk of chain
breakage and/or increased dust
exposure!
Objects to be cut
Must be fully supported
–
Must be secured so they cannot roll
–
or slip off
Must be prevented from vibrating
–
Severed workpiece parts
With openings, recesses, etc., the
sequence of the cuts is important.
Always make the last cut so that the
diamond abrasive chain does not
become jammed and so that the
operator is not endangered by the
severed or separated part.
If necessary, use wedges and if
necessary, leave small ridges that hold
the part that is to be separated in
position. Break these ridges later.
GS 461
Before finally separating the part,
determine:
support or secure properly
–
how heavy the part is
–
how it can move after separation
–
whether it is under tension
–
When breaking out the part, do not
endanger bystanders.
Plunge-cutting
Begin cutting with the concrete cutter at
full throttle.
3.
2.
1.
1. Apply the lower portion of the guide
bar nose.
2. Swing slowly into the plunge-cutting
position.
3. Make the plunge cut very carefully.
WARNING
When making the plunge cut into
existing, narrower joints, proceed with
extreme care. The sides of the narrower
cut could pinch the chain in the upper
quadrant of the bar tip and lead to
reactive forces. See the section entitled
"Reactive Forces."
Cut in several passes
A
Mark cutting line (A).
N
Work along the cutting line. When
N
making corrections, do not tilt the
diamond abrasive chain, always
withdraw the bar and reposition it.
