BVA Hydraulics P1201, P1201S, P2301, P2301M, P4301 - Manual (Page 6)

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 Mobil
DTE 13M or equivalent. Never use brake fluid, 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
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” (6mm) 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 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 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 thoroughly
3. Store in clean, dry environment. Avoid temperature
extremes.
4. Shield pump with a protective cover.
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 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.
