Cooling

Risk of burning when touching hot surfaces
There is a risk of burning when touching hot surfaces immediately after the motor has been
operational.
•
Danger to life when the cooling system bursts
The motor will overheat if it is operated without cooling. When cooling water enters the hot
motor, this immediately and suddenly generates hot steam that escapes under high
pressure. This can cause the cooling water system to burst, resulting in death, severe injury
and material damage.
•
•
Risk of burns when hot cooling water escapes
There is a risk of burns caused by escaping hot cooling water and steam if you open the
cooling circuit of a motor that was previously in operation.
