BEFORE USE
Read all instructions carefully before attempting to assemble
or operate this pump. Most malfunctions in new equipment
are the result of improper operation and/or improper set-up
assembly.
Visually inspect all components for shipping damage. Do not
use if any damage is found.
Note: E-Pump is shipped without hydraulic oil filled. Add oil
before starting motor and operation.
Familiarize yourself with the specification and illustrations in
this owner manual. Use service parts drawing as reference
of location and assembly.
!
Electrical Connections:
1. Compare motor nameplate against power availability
to prevent motor burnout or dangerous electrical
overloading.
2. The motor is wired for 110 volts unless otherwise specified,
and are supplied with a plug and 3 prong cordset.
Motor, connections and remote pendant switch are
energized components containing line voltage!
Ensure supply is grounded and GFI protected!
Hydraulic Connections:
1. Make sure to use the hydraulic oil specified by the
manufacturer. Check and make sure the oil level in
reservoir is at about 2” from top of reservoir plate, with
cylinders retracted and motor off.
2. There are two oil output ports on this pump. CONNECT
HYDRAULIC CONNECTION TO ONE OIL PORT ONLY.
Connect to either one of the oil ouput ports and make
sure the other port is plugged and tighten properly.
3. Use of pressure gauge is strongly recommended. Attach
a pressure gauge between the pump and cylinder to
monitor pressure on cylinder.
4. Make sure coupler, hose, valve, gauge are tightened
securely to prevent accidental removal of components
while in use. Hoses must not be kinked or twisted.
Note: When the valve is in RELEASE position, the
cylinder advances when the pump is running and
retracts when the motor is stopped.
When the valve is in the HOLD position, the cylinder
advances when the pump is running and, holds when
the motor is stopped. The cylinder can be retracted
by moving the flipper control valve to the RELEASE
position.
Note: To ensure smooth operation, bleed air from the system
by fully advancing and retracting the cylinder several times.
Note: Do not continue to operate pump after cylinder plunger
is fully extended or retracted.
Note: Always secure threaded port connections with non-
hardening pipe thread compound. Take care not to introduce
compound into port orifices.
5. Do not exceed the rated capacity of the equipment
connected to the pump. Use larger capacity cylinders if
necessary. To reduce system component stress, material
fatigue, and the risk of personal injury and property
damage, never load a hydraulic application (cylinder,
spreader, etc.) more than 80% of its rated capacity.
The pump’s maximum working pressure is 10,000 psi. Make
sure that all hydraulic equipment such as cylinders, hoses,
coupler, etc. used with this pump are rated at 10,000 psi or
greater.
