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 uid. We recommend
Mobil DTE 13M or equivalent. Never use brake uid,
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.
Adding Hydraulic Fluid (refer to Fig. 3)
1. Depressurize and disconnect hydraulic hose from
application.
2. With pump in its upright, horizontal position, remove oil
ller screw located at the rear end cap.
3. Add appropriate hydraulic uid until level with oil ller
hole.
4. Wipe up any spilled fluid and reinstall the oil filler
screw.

TROUBLESHOOTING GUIDE
The following information is intended as an aid in determining if problem exists. Pumps should be repaired only by authorized
BVA Service 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 application
• Tighten all connections
• Contact service center
Application does not extend,
move or respond to pressurized
uid
• 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 uid, 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 tting
• Application/connection leaking
• Tighten connection or coupler
• Clean and replace if damaged
• Replace application/connection
Application does not return uid to
pump (i.e. cylinder will not retract)
• Malfunctioning coupler, damaged
application
• Reservoir overlled
• 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
uid to proper level.
Poor performance • Fluid level in pump is low • Ensure proper uid level
Paint contains lead!
DO NOT sand or grind painted surface!

Changing Hydraulic Fluid
For best results, change uid once a year.
1. Remove ller screw and drain used uid into a sealable
container.
2. Dispose of uid in accordance with local regulations.
3. Fill with a good quality hydraulic oil as recommended above.
Reinstall vented oil ller 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 thoroughly
3. Store in clean, dry environment. Avoid temperature
extremes.
4. Shield pump with a protective cover.
