Power Supply
The power supply is AC110V or 220V 50/60Hz single phase. Make sure your line voltage is compatible with your pump.
The wrong voltage connection or voltage drop of your line will cause burning or heating.
1. BE CAREFUL ABOUT VOLTAGE DROP WHEN USED WITH AN ELECTRIC GENERATOR.
2. When the power supply is disconnected, ALWAYS GRASP THE POWER PLUG AND PULL IT OUT. Disconnect by
grasping the cord and pulling it out will cause breaking of a wire or a short circuit.
3. When a supplement cord is used, use only three-wire grounded cords of such sufficient gauge as 1.25mm2or more
with a maximum length of 10M. This will help to avoid voltage drop or damage of the solenoid valves or the electric
motor.
CAUTION
!
!
Using the Pump
Be Sure to Take Appropriate Safety Measures
When hydraulic equipment is operated, protect yourself with a personal safeguard, working clothes and shoes, safety
glasses, etc.
Always Check Pressure Limitations of the Hydraulic Circuit
Always confirm in advance that maximum permissible working pressure of a hydraulic pump is lower than the pressure
rating of the lowest rated component connected in the system.
1. 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.
2. DO NOT OPERATE PUMP BY THE SIDE OF AN ELECTRIC WELDER.
3. DO NOT PLACE THE PUMP ON EARTHED MATERIALS OR EQUIPMENT.
WARNING
!
1. DO NOT USE PUMP IN THE RAIN OR ON/IN WET AND DUSTY PLACES.
2. DO NOT EXPOSE HYDRAULIC SYSTEM TO THE DIRECT RAYS OF THE SUN. Be careful with unacceptable rise in
hydraulic oil temperature, which can cause trouble in hydraulic equipment.
3. In the case pumps are used outdoors in extremely cold regions, exchange oil for hydraulic oil with the proper viscosity.
Increased viscosity due to a drop in oil temperature may cause equipment to function improperly.
CAUTION
!
Cautions When Installing Pump
Install a pump unit for better balance
Since the reservoirs of totally enclosed rubber structures are used in these series of pumps, the pumps can be placed for
use in any position (slanted, inverted, or perpendicular). However, the pumps should be installed on stable places. When
a pump is used aslant, make sure it is firmly affixed to prevent sliding which may result in damage or personal injury.
Prepare a suitable working environment
Make sure all system components are protected from external sources of damage such as excessive heat, flame, moving
machine parts, sharp edges, or corrosive chemicals.

Instructions Before Use
1. Inspection of all components for shipping damage or oil leakage. If any shipping damage is found, notify carrier at
once. Shipping damage is not covered by warranty. The carrier is responsible for all repair or replacement costs
resulting from damage in shipment.
2. Oil feeding plugs (Code No.5) are always shut tightly when in shipment and even in use because
the tanks are completely enclosed. Use them together with quick couplers with check valves.
3. Check your power supply. Power supply is AC110V or 220V 50/60Hz single phase. Make sure
that a grounded outlet or a plug adapter with a grounding attachment must be used.
4. Check hydraulic oil. Always check oil level before operation with the connected cylinders fully
retracted (extend if pull cylinders). In case oil is added with cylinders fully extended and then
cylinders are retracted, the returned oil will overflow in the reservoirs causing generation of high pressure in the
reservoirs. Verify required oil volume in a reservoir as follows:
a) Retract the connected cylinder fully.
b) Pull power plug out.
c) Turn oil feeding plug counterclockwise and remove it.
d) Clean the oil gauge of the removed oil feeding plug with a piece of cloth and put it in the oil feeding port again to
check oil level. BE CAREFUL WITH THE O-RING.

Pressure and Piping
1. Composition of hydraulic equipment system. When a pump, high pressure hose(s), cylinder, valve,
or couplings are connected together, always check product limitations regarding pressure ratings
and load capacities. The system operating pressure must not exceed the pressure rating of the lowest rated compo-
nent in the system.
2. Pressure gauges. Always install or prepare a pressure gauge in-line from the pump in order to monitor pressure.
3. Piping. Use wrapping of teflon tape on hose fittings, valves and couplers. Make sure all hose
connections are tight - use proper tools to tighten connections with reference to the following table.
DO NOT OVERTIGHTEN CONNECTIONS.
*Make sure that tape does not shed into the hydraulic system causing damage. Trim loose ends.

Oil Exchange
The frequency of oil change depends upon general working conditions, severity of use, and overall
cleanliness. 300 hours (working time) of use or about 3 months is considered as a standard change
interval. Periodically compare samples of the reservoir oil with new oil. Inspect oil color for contaminants or differences.
Remove oil feeding plug and tilt the pump to drain out old oil. Be careful that impurities such as dust do not enter into
the reservoir and that new oil is filled up to the gauge level mark indicated in the pump. Precautions for oil change are:
a) Reatract all cylinders fully to the return position.
b) Do not fill with even a small quantity of replensihment of different kinds of oil.
c) Be careful that impurities or foreign matter do not enter into new oil.
Oil Safety Notes
When oil enters into the eyes, wash it away fully with clean water and consult a doctor immediately
In case oil enters into an open wound, wash it away with soapy water and quickly consult a doctor.

e) It is OK if the reservoir is filled with oil reaching to the upper bound of the oil gauge. Replenish of oil is short
(See Maintenence section) for hydraulic oil details.
f) Replace the oil feeding plug and screw it in by turning counterclockwise.
Operation
When using a pump with an opened type, turn the oil supply cork twice counterclockwise at the time of use.
NOTE: TURN CLOCKWISE AT THE TIME OF CONVEYANCE AND FASTEN THE OIL SUPPLY CORK. When using a pump
with a sealed type, use it with the oil supply cork fastened.
1. Close the release valve lever by turning clockwise and depress the "ON" switch to advance the plunger.
2. To retract the plunger, turn the valve lever counterclockwise to open the valve.
Maintenance
Hydraulic Oil
Use only ZINKO hydraulic oil or an approved high grade oil (ISO #32, viscosity: 32 cSt @40oC) with these pumps.
Oil Temperature
Aptitude temperature for use of hydraulic oil is maximum 55oC. If the color of the temperature seal attached to the tank
has changed and indicated "55" as shown below, an unacceptable rise in oil temperature has occured. STOP WORKING
IMMEDATELY to decrease the oil's temperature. Installation of an oil coller may be appropriate.

Relief Valve Adjustment
Range of standard pressure adjustment available is from 58.8 to 68.6MPa. Loosen lock screw on the high pressure relief
valve and turn the adjusting screw a few turns counterclockwise to decrease pressure setting to a lower desired pressure.
Clockwise rotation of the adjusting screw will increase pressure. After setting pressure, replace the lock screw. NOTE: A
different kind of spring is needed to adjust and set at a lowe pressure than standard. Consult a ZINKO authorized dealer.
WARNING
!
6mm
Carbon Brushes
Always check the wearing condition of the carbon brushes. When the carbon brushes have been worn
down and replacing them is necessary, the motor will stop automatically. Replace when a brush has
been worn down to 6mm in length as shown below, or working time of the motor is 500 hours or more (NOTE: Carbon
brush replacement times may depending on the conditions of use). Use only ZINKO approved brushes with these pumps
to extend the life of the unit(s). When they have been worn down the spring exerts insufficient pressure to hold brush
against the commutator.
How To Change
1) Disconnect the power supply.
2) Remove rubber caps on two places and loosen (Code No. 1-21).
3) Remove fitting screws inside with a screwdriver so the
carbon brush can be taken out.
4) Replace brushes with new ones and reattach the screws
and rubber caps.
Bleeding Air From the System
Reservoirs of ZPE-35RH series pumps are made of totally enclosed rubber tanks and tank covers.
Rubber tanks are filled with oil making no room for air accumulation. However, in case a new cylinder
and/or new hose is connected with the pump or oil is exchanged, air may accumulate in the hydraulic system. This air
will prevent the pump from delivering oil or cause the cylinder to respond in an unstable or slow manner. Be careful with
air accumulation in the system. To remove air:
a) Make sure the tank is full with oil. Open the oil supply cork on the upper part of the pump, check the quantity of oil
and carry out until full.
b) When oil does not come out or pressure does not rise when a return valve is opened, push the button on the operation
switch about 10 times and perform air omission of the pump.
c) Air may accumulate in the pump (rubber tank) when hydraulic equipment is connected. Always check and confirm that
the oil tank is full before use.
CAUTION
!
Quick Couplers
Connections
Make sure that all couplers are connected properly. Incomplete coupling connections might cause partial or complete
blockage of oil flow resulting in trouble of hydraulic system.
Handling
If the coupler becomes damaged, stop operating the pump. The damaged coupler can cause a serious
accident. DO NOT DISCONNECT COUPLER SETS, they are under pressure.
WARNING
!
High Pressure Hoses
1. Hose Installation. Install hoses leaving something in the reserve because high pressure hoses expand
and contract more or less when full pressure is applied. Be careful that the hoses do not rub against
other soild materials. Never allow the hoses to kink, twist, curl or bend so tightly that oil flow within hoses are blocked
or restricted. DO NOT CLAMP THE HOSES. Clamping the hoses can cause problems.
Hose Handling
Never drop heavy things against the hoses. This can cause bursting of the hoses resulting in serious
accident or injury. Do not subject the hoses to any potential hazard (fire, extreme heat or cold, heavy
impact, or sharp surfaces), which may rupture or weaken the hoses. Never pull hoses to move or lift equipment connect-
ed with hoses.
Should a hose ever burst or rupture, STOP OPERATING THE PUMP IMMEDIATELY before attempting to remedy the
situation. Never attempt to grasp a leaking hose under pressure with your hands. The force of the escaping hydraulic
fluid could cause serious permanent injury.
