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.

TROUBLESHOOTING
A system failure may or may not be the result of a pump malfunction. The following information is intended to be used as an
aid in determining if a problem exists. Pumps should be repaired only be repaired by authorized BVA Service Center.
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 Hydraulics
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 BVA hydraulic oil, Mobil DTE 15M or
equivalent. To order the oil, refer to service parts section.
Use
only
the manufacturers recommended hydraulic oil.
Use of other hydraulic oil may result in pump failure
and will void warranty.
Adding Hydraulic Oil
1. Make sure electric motor is OFF.
2. Depressurize and disconnect hydraulic hose from
application.
