Center. For repair service, contact service center in your area.
Symptom
Possible Causes
Corrective Action
Erratic application action
• Air in the system.
• External leak.
• Internal hydraulic leak.
• Vent the system.
• Tighten all connections.
• Contact service center.
Application does not extend, move
or respond to pressurized fluid
• Overload condition.
• Release valve not closed.
• Loose couplers/connections.
• Faulty couplers/connections.
• Pump malfunction.
• Remedy overload condition.
• Ensure release valve closed.
• Tighten couplers/connections.
• Replace couplers/connections.
• Contact service center.
Application responds to pressurized
fluid, but system does not maintain
pressure
• Overload condition.
• Release valve not closed.
• Pump or valve malfunction.
• Application/connection leaking.
• Remedy overload condition.
• Ensure release valve closed.
• Contact Service Center.
• Replace application/connection.
Application responds slower than
normal
• Loose connection or coupler.
• Restricted hydraulic line or fitting.
• Application/connection leaking.
• Tighten connection or coupler.
• Clean and replace if damaged.
• Replace application/connection.
Application does not return fluid to
pump (i.e. cylinder will not retract)
• Malfunctioning coupler, damaged
application.
• Reservoir overfilled
• Secure load by other means. Open release
valve, depressurize pump and hose,
remove coupler and/or application, then
renew or replace.
• Secure load by other means. Open release
valve, depressurize pump and hose,
remove application, then drain fluid to
proper level.
Poor performance
• Fluid level in pump is low.
• Ensure proper fluid level.

MAINTENANCE
1. Inspect hoses and connections daily. Replace
damaged components immediately with BVA Hydraulics
Replacement Parts only.
2. Tighten connections as needed. Use pipe thread
sealing compound when servicing connections.
3. Use only good quality hydraulic fluid. We recommend
using premium hydraulic fluid.
Never
use brake
fluid, transmission fluid, turbine oil, motor oil, alcohol,
glycerine etc. Use of other than good quality hydraulic
oil will void warranty and damage the pump, hose, and
application.
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hose from
application.
2. With pump in its upright, horizontal position, remove
vented oil filler plug/screw located on top of the
reservoir.
3. Use a small funnel to fill reservoir to within 1/4” (6 mm)
of the opening.
4. Wipe up any spilled fluid and reinstall the vented oil
filler plug/screw.
Changing Hydraulic Fluid
For best results, change fluid once a year.
1. Remove vented oil filler plug/screw and drain used fluid
into a sealable container.
2. Dispose of fluid in accordance with local regulations.
3. Fill with a good quality hydraulic jack oil as
recommended above. Reinstall vented oil filler plug/
screw.
Lubrication
Use a light machine oil to lubricate pivot points, hinges etc.
Storage
1. When not in use, depressurize and disconnect hoses
from application.
2. Wipe clean, throughly
3. Pump should be stored where protected from the
elements, abrasive dust, and damage. Store in clean,
dry environment. Avoid temperature extremes.
4. Shield pump with a protective cover.
