WARNINGS
One terminal of an electric plug is ground (earth) terminal.
To prevent electric shock, ensure that the power socket
satisfies the requirements for appropriate ground
installation specified by local standards in each country.
Ensure that wiring at the electric plug and electric outlet is
correct before connecting.
Tighten the cap nut of the coupler (S-1, 2, 5) by hand
completely until the head of the nut is flush with the lip of
the hose coupler. Cylinders will not operate smoothly if a gap is left as shown in the diagram
below. When using double acting cylinders, should the pull or retract side coupler not be
completely closed, excessive pressure will be generated in the retract or pull side of the
cylinder just by a normal pressure on the push cylinder side. This will cause damage to the
coupler, cylinder and/or high pressure hose and may also result in a serious bodily injury.
Do not place hands or other body parts near areas where hydraulic oil is being dispersed as
high pressure oil may penetrate the skin and cause serious injury.
If oil contacts an eye, thoroughly flush the eye with clean water immediately for at least 15
minutes and consult a doctor. Also, if oil contacts the skin, wash thoroughly with water and
soap.
Do not set the pressure switch to the setting mode during operation of the pump. The motor
stops when the setting mode is activated and restarts if
□
E button is pressed. These
procedures lead to malfunction may cause any accident or injury.
In case of EMP-5TK, do not use a self-sealed quick coupler, and be sure to use a low pressure
rubber hose with a union to reduce resistance at return route piping from a directional control
valve mounted externally. A directional control valve may be damaged if a self-sealed quick
coupler is clogged, resulting in a bodily injury.
Do not grip a pressurized high pressure hose with a hand. If it breaks while being gripped,
high-pressure hydraulic oil spouts out instantaneously and may penetrate the skin, causing
serious injury.
The high pressure hose is a consumable item. Even if the hose appears to be in good
condition, it is possible internal damage such as pin holes or scars have occurred. Riken
recommends periodic replacement based upon how frequently hoses have been used
combined with specific application conditions, even if the life span has not fully expired.
CAUTIONS
Use ISO VG32 hydraulic working oil (RIKEN POWER OIL) only. Phosphoric ester, water-glycol,
and w/o emulsion oil should not be used; if any of them is used, the packing seals will
deteriorate and the equipment will fail due to corrosion or others. Consult RIKEN or RIKEN’s
authorized agents if these kinds of unapproved oils are used. Ensure
that the oil level is lower
than the maximum level line of the oil gauge when adding oil to the oil tank.
Do not use the high pressure safety valve as a relief valve. Install a separate relief valve if it is
necessary to perform continuous relief.
Ensure to screw 4 eye bolts (Hanging bolt) into the application thoroughly before hanging the
pump.
When an air relief valve (SV-1000) is installed and air release is performed, hydraulic oil will
come out of the discharge holes of the air release valve. Use a cloth or other suitable material
to prevent dispersion of the oil.
Waste oil generated by the pump is classified as an “Industrial Waste Product”. Consult the
local regulatory agencies and dispose of the oil through a licensed industrial waste collection
agency or industrial waste processing agency.
