0.3 Safety Precautions
When evacuating toxic or inflammable gas, there may be danger of leaking
gas from parts besides inlet port. Practice cautionary steps when working
any kind of gases.
After evacuating toxic gases, the inside of pump and pump oil is
contaminated and toxic. Therefore, handle pump with care during
maintenance.
Do not overhaul or repair this pump.0nly authorized maintenance personnel
should handle this pump to avoid ignition, abnormal action, and electric
shock.
Switch off power before checking or repairing the pump to avoid any
problems (electric shock or personal injury) caused by suddenly starting
up.
Connect an electrical wire cord to ground potential terminal tightly to
avoid electric shock caused by mechanical trouble or electrical leakage.
Do not plug exhaust port or place any materials inside of exhaust port,
because it will reduce pumping speed during operation. Pump explosion,
oil level gauge bursting, or motor over loading are consequences of
excessive pressure inside the pump. This pump is not a compressor. The
maximum pressure inside this pump is 0.03 MPa (GAUGE).
