chological state and may lead to lack of attention and irritation.

Hazards due to hot surfaces
Surfaces of the low-pressure and high-pressure stage, attached parts and operating fluids
(lubricating oil) get hot during operation. The surface temperature depends on the efficacy
of the existing insulation. The temperature may rise to a level that can cause burns.

Danger of burns
Touching hot surfaces or contact with hot operating fluids can cause severe
burns.
Do not touch hot surfaces. Observe the warning plate on the low-pres-
u
sure and high-pressure stage.
Wear heat-resistant safety gloves and protective clothing.
u
Wait for the low-pressure and high-pressure stage to cool down before
u
carrying out any work.
