Troubleshooting Guide - BVA Hydraulics P1201 Manual De Instrucciones

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.
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
Erratic application action
Application does not extend, move
or respond to pressurized fluid
Application responds to pressurized
fluid, but system does not maintain
pressure
Application responds slower than
normal
Application does not return fluid to
pump (i.e. cylinder will not retract)
Poor performance

TROUBLESHOOTING GUIDE

Possible Causes
• Air in the system.
• External leak.
• Internal hydraulic leak.
• Overload condition.
• Release valve not closed.
• Loose couplers/connections.
• Faulty couplers/connections.
• Pump malfunction.
• Overload condition.
• Release valve not closed.
• Pump or valve malfunction.
• Application/connection leaking.
• Loose connection or coupler.
• Restricted hydraulic line or fitting.
• Application/connection leaking.
• Malfunctioning coupler, damaged
application.
• Reservoir overfilled
• Fluid level in pump is low.
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.
• Vent the system.
• Tighten all connections.
• Contact service center.
• Remedy overload condition.
• Ensure release valve closed.
• Tighten couplers/connections.
• Replace couplers/connections.
• Contact service center.
• Remedy overload condition.
• Ensure release valve closed.
• Contact Service Center.
• Replace application/connection.
• Tighten connection or coupler.
• Clean and replace if damaged.
• Replace application/connection.
• 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.
• Ensure proper fluid level.
