Caution when used
WARNING
■ Take safety measures.
When hydraulic equipment is operated, protect yourself with a personal safeguard,
working clothes and shoes, safety spectacles, etc.
■ Always check pressure limitations of hydraulic circuit.
Always confirm in advance that max. permissible working pressure of a hydraulic pump is
lower than the pressure rating of the lowest rated component connected in the system.
■ Be careful to avoid electric shock.
Do not pull power plug out with a wet hand. Use a grounded outlet or a plug adapter with
a grounding attachment in order to protect the operator from electric shock. Do not operate
the pump by the side of electric welder or do not place it on the earthed materials or
equipment.
CAUTION
■ Power supply is AC220V 50/60Hz single phase.
Make sure your line voltage must be the same as the voltage your pump is wired for.
Wrong voltage connection or voltage drop of your line shall cause burning or heating.
Be careful about voltage drop when used with an electric generator.
■ When the power supply is disconnected, always grasp the power plug and pull it out.
Disconnection by grasping the cord and pulling it out will cause breaking of a wire or a
short circuit.
■ When a supplement cord is used, use only three-wire grounded cords of such sufficient
gauge as 1.25mm
2
or more, its length of max. 10M, in order to avoid voltage drop or
damage of the solenoid valves or electric motors.
