Please note that the foreign matters may enter your eyes at the time of air blow.
● Please note that the oil will flow out from the pipe during decomposition. And please make sure that there
is no residual pressure in the pipe.
●
If the hydraulic oil in the pipe and cylinder came back to the tank, there is a risk of overflow from the tank.
Do not let the hydraulic oil in the cylinder flow to the tank. Please let the oil return to the oil pan.
