To prevent lock-in, observe the following:
•
When reinserting the disc into previous cuts,
have the Certa Petrol Demolition Concrete
Saw running at top speed. Always cut at top
speed.
•
Always support the workpiece so that the cut
is under tension
16
so that the cut does not
press together and jam the cutting disc as it
proceeds through the material.
•
When starting a cut, apply the disc to the workpiece with care. Do not just shove it into
the material.
•
Never cut more than one piece at a time! When cutting, make sure that no other
workpiece comes into contact.
•
Gyroscopic forces come into play when handling a Certa Petrol Demolition Concrete
Saw with a rapidly rotating composite wheel.
•
To prevent gyroscopic forces developing, note the following: Do not rotate the
machine
rapidly about its longitudinal axis!
•
Be warned” If gyroscopic forces are present, the saw will react in an uncontrolled
manner, and there is a danger that injuries may occur.
Working behaviour/Method of working
•
Check the integrity of the composite wheel both before and after fitting it to the
machine.
•
Before starting work, check the work area for any hazards (electrical wires, inflammable
substances) marks the work area (for example with warning signs or by cordoning off
the area).
•
When working with the Certa Petrol Demolition Concrete Saw, hold it firmly by the
front and rear handles. Never leave the Certa Petrol Demolition Concrete Saw
unattended!
