or before machine shutdown，please use PP material to clean the barrel.
★Prior to move the carriage forward，be sure to close the mold.
2.5 Hydraulic unit
★Do not set pressure over the maximum system operation pressure according to machine
specification.
★Power off machine and wait for no residual hydraulic pressure before disassemble any
hydraulic or mechanical parts.
★When damage is found on the high pressure hose，replace it immediately；otherwise，
when the high pressure hose is ruptured，the high pressure hydraulic oil will erupt thus
causing injury to the personnel.
★The operation temperature of hydraulic oil is 35℃-50℃，continuous operation between 20
℃-55℃ is allowed；however，when the temperature is below 20℃，please perform oil
pre-heat process to heat up the temperature，oil temperature less than 20℃ will make the
system very unstable.
★When the hydraulic hose or valve is found loose，please tighten them up immediately thus
preventing oil leakage or other problems.
2.6 Electrical unit
★Turn the power off before opening the control cabinet to prevent electrical shock.
★Turn the power off before removing the barrel guard.
★Turn the power off before replacing the heater band.
★Turn the power off before wiring the circuits in the terminal box of heater band.
★Make sure the machine has been properly and independently grounded(earthed)，phase N
shall not be in connection with grounding G.
★Make sure no water accumulated in the machine to prevent the water from getting into the
electrical control cabinet and result in electric leakage or damage on the machine.
