BVA P350 - Maintenance; Troubleshooting Guide

OPERATION (con’t)
NOTICE: operate pump handle at slower speed during the high
ow 1st stage to ensure the pump delivers maximum oil volume.
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using
premiumhydraulicuid.Neverusebrakeuid,transmission
uid,turbineoil,motoroil,alcohol,glycerineetc.Useofother
than good quality hydraulic oil will void warranty and damage

Changing Hydraulic Fluid
For best results, change uid once a year.
1. Remove vented oil ller plug/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 jack oil as recommended above.
Reinstall vented oil ller 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. Lock handle into position using
the spring loaded locking pin mechanism.
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 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.
