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 (F01 & F05), 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.
