work practices and respiratory
protection to reduce exposure to
respirable crystalline silica or other
potentially harmful substances.
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 leave
small ridges that hold the part that is to
be separated in position. Break these
ridges later.
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.
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
N Mark cutting line (A).
N Work along the cutting line. When
making corrections, do not tilt the
diamond abrasive chain, always
withdraw the bar and reposition it.
Cutting Round and Hollow Bodies
N Secure pipes, round bodies, etc.
against rolling away.
N Mark a cutting line - when
determining the cutting line, avoid
reinforcement, especially in the
direction of the severing cut.
N Make the plunge cut very carefully.
N Feed with bar completely through
the wall of the workpiece along the
cutting line – for small corrections of
direction, do not tilt the diamond
abrasive chain, but always position
it anew instead – if necessary, use
wedges and if necessary, leave
