Empire EMT-7R, Instruction & Parts Manual

Page: 32 / 46

BEFORE USE AND SET UP
1. Familiarize yourself with the specifications and
illustrations in this owners manual. Know your pump,
its limitations and how it operates before attempting to
use. Refer to specification chart on page 3 for details
of oil port thread size, usable oil capacity, and more.
If in doubt, contact BVA Hydraulics Technical Service
(888) 332-6419.
2. For model PA1500: Replace shipping plug
(red color) with air vent plug (black color)
before use.
3. Air Connection: Remove plastic cap, connect suitable
air supply to air input port. Air input port is designed to fit
the popular 1/4" NPT air nipple (not included). Ensure
that your air source can dedicate 7.8CFM @ 110~175 PSI
to each pump operated.
4. Hydraulic Connection: Clean all areas around the oil
port of pump and cylinder. Inspect all threads and fitting
for signs of wear or damage and replace as needed.
Clean all hose ends, couplers and union ends. Remove
the manifold plug, then connect oil output port to suitable
fittings and application/cylinder.
IMPORTANT : Always secure threaded port connections
with high grade, non-hardening pipe thread sealant. Teflon
tape can be used if only one layer of tape is used and it
is applied carefully, two threads back, to prevent the tape
from being introduced into hydraulic system, which could
cause jamming of precision-fit parts.
To reduce the risk of personal injury and/or property
damage, Hydraulic connections must be securely fastened
before building pressure in the system. Release all system
pressure before loosening any hydraulic connection in the
system.
OPERATION
Always monitor pressure, load or position using suitable
equipment. Pressure may be monitored by means of an
optional manifold and gauge. Load may be monitored by
means of a load cell and digital indicator. Correct application
position can only be determined by the operator of the
equipment.

For Models PA1500:
1. To extend the cylinder, depress on the foot pedal
until desired position is reached.
2. To hold the cylinder in position, release the foot pedal to
the half way detent to
deactivate the pump.
3.
T
o retract the cylinder, release foot pedal
Note:
Never operate a pump which is disconnected from
application. If operate in this condition, the hose and
connections will become pressurized. This increases burst
hazard. Damage may occur to pump and its components.
MAINTENANCE
Important:
Use only good quality hydraulic fluid.
Never
use
brake fluid, transmission fluid, turbine oil, motor oil, alcohol,
glycerin etc. Use of other than good quality hydraulic oil will
void warranty and damage the pump, hose, and application.
We recommend Mobil DTE 13M or equivalent.
1. Inspect hoses and connections daily. Replace damaged
components immediately.
2. Tighten connections as needed. Use non-hardening pipe
thread compound when servicing connections.
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hose from
application/ cylinder.
2. For Model PA1500:
With pump in its upright, horizontal position, remove the
air vent plug located on the top plate of the reservoir.
3. Use a small funnel to fill the oil to within 3/4" (19mm)
of the opening.
4. Wipe up any spilled fluid and reinstall the air vent plug/
reservoir cap.
Changing Hydraulic Fluid
1. For best results, change fluid once a year or every 300
hours of use.
2. Repeat # 2 above, then pour used fluid into a sealable
container.
3. Dispose of fluid in accordance with local regulations.
4. Fill with a good quality hydraulic fluid as recommended
above. Reinstall air vent plug/ reservoir cap.
Lubrication
When pump is operated on daily basis, the manufacturer
recommends installing an inline oiler and air dryer. Use SAE
grade oil (5W to 30W).
Storage
1. When not in use, depressurize and disconnect hydraulic
pump from application.
2. Wipe clean, thoroughly and store in clean, dry
environment. Avoid temperature extremes.
3. For transportation or long storage, replace the air vent
plug with shipping plug (for model PA1500).
