! DANGER
TO AVOID ELECTROCUTION HAZARD:
• Do not operate this device in an explosive atmosphere or
in the presence of conductive liquids.
• Owner, Operator must read, understand and
follow all printed material provided with this
device before use.
• Connect ONLY to properly grounded electrical
source. Connect to GFI outlet ONLY! For use
in dry locations.
• Avoid the use of extension cords. If used, extension cord
lengths up to 25 ft shall be SJT-14X3 or heavier. For cords
up to 50 ft, use SJT-12X3 or heavier. For extension cord
lengths up to 100 ft, use SJT-10X3 or heavier. NEVER
use a 3 prong adapter.
OPERATION
Note: A dump valve with 2-way, 2-position is equipped on the
pump to use with Single-acting cylinders or applications.
1. Check oil level, add oil if necessary.
2. Make sure system fittings and connections are tight and
leak free.
3. Turn the flipper control valve counter-clockwise to HOLD
position.
4. Start the pump by pressing and holding the switch on
remote pendant. Oil advances the cylinder or application
when the unit is activated.
5. Always monitor the pressure, load and position.
6. Release the switch on remote pendant when desired
pressure, load or position is reached.
7. To retract the cylinder or application, turn the flipper control
valve clockwise to RELEASE position.
8. Depressurize all connections before disconnect.
MAINTENANCE
1. Keep areas around pump unobstructed in order to provide
good air flow around the motor and pump. Try keep the
motor and pump as clean as possible.
2. Inspect hoses and connections daily. Replace damaged
components immediately with BVA replacement parts
only.
3. Tighten connections as needed. Use non-hardening pipe
thread compound when servicing connections.
4. Check hydraulic oil level every 40 hours of operation. Add
hydraulic oil if necessary.
5. Completely change the hydraulic oil every 300 hours of
operation. Change the oil more frequently when pump is
used in an extremely dusty environment or when the oil
has been overheated. Use only good quality hydraulic oil.
We recommend Mobil DTE 15M or equivalent. To order
the oil, refer to service parts section.
Note: Use only a good quality hydraulic oil. Never use brake
fluid, transmission fluid, turbine oil, motor oil, alcohol, glycerin
etc. Use of other than recommended hydraulic oil, will void
warranty and damage the pump, hose, and application.
Adding Hydraulic Oil
1. Make sure electric motor is OFF.
2. Depressurize and disconnect hydraulic hose from
application.
3. Remove vent cap on the top plate of the reservoir.
4. Use a funnel to fill reservoir to about 2” from top of reservoir
plate.
5. Wipe up any spilled fluid and reinstall the vent cap.
Changing Hydraulic Oil
1. For best results, change hydraulic oil once a year.
2. Remove drain plug, tilt the pump then pour used fluid into
a sealable container.
3. Dispose the hydraulic oil in accordance with local
regulations.
4. Fill hydraulic oil, then reinstall vent cap.
Cleaning
Clean oil filter screen periodically with nonflammable solvent,
then blow dry before reassemble back to pump.
Storage
1. When not in use, depressurize and disconnect hydraulic
hoses from application.
2. Wipe clean, thoroughly.
3. Store in clean, dry environment. Avoid temperature
extremes.
4. For transportation or long term storage, shield pump with
a protective cover.
