period (free-wheeling effect).
•
Continuously ensure that you have a safe footing.
•
Hold the Certa Petrol Demolition Concrete Saw such that you will not
breathe in the exhaust gas. Do not work in closed rooms or deep holes or
ditches (danger of poisoning by fumes).
•
Warning:
Carbon monoxide produced during use can kill-do not use Certa Petrol
Demolition Concrete Sawter indoors-make sure there is proper ventilation when using
Certa Petrol Demolition Concrete Saw in trenches or other confined spaces.
•
Switch off the Certa Petrol Demolition Concrete Saw immediately if you observe any
changes in its operating behaviour.

Important:
After wet cutting, first turn off the water feed and then let the disc run at
least 30 seconds, to fling off the remaining water and prevent corrosion.
Kickback, lock-in and gyroscopic forces
•
When working with the Certa Petrol Demolition
Concrete Saw there is a danger of kickback and
lock-in.
•
Kickback occurs when the top of the cutting disc
is used for cutting.
15
•
This causes the Certa Petrol Demolition Concrete Saw to be thrown back toward the
user with great force and out of control.
Risk of Injury!
To prevent kickback, observe the following:
•
Never cut with the section of the cutting disc shown in Figure 15. Be especially careful
when reinserting the disc into cuts that have already been started!
•
Lock-in occurs when the cut narrows (crack or workpiece under stress).
•
This causes the Certa Petrol Demolition Concrete Saw to suddenly jump forward, out
of control and with great force.
Risk of injury!
•
Refuelling
•
Changing cut-off discs
•
Stopping work
•
