will get covered by ice during air expansion.
Therefore, when starting the compressed air motor, observe the following items (→Fig.1):
• Before connecting the motor to the compressed air supply, clean the compressed air line and the hose
by blowing out with low pressure to remove any dirt particles from the line. Wear safety goggles, hold
thelinetightanddonotstandintheareaoftheairow.
