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 ap-
plication
• Secure load by other means.
Depressurize pump and hose,
remove coupler and/or application,
then renew or replace
Application does not fully extend (cyl-
inder or spreader)
• Reservoir overlled
• Fluid level in pump is low
• Secure load by other means.
Depressurize pump and hose,
remove application, then drain uid to
proper level
• Secure load by other means.
Depressurize pump and hose,
remove application, then ll uid to
proper level
Poor performance • Fluid level in pump is low • Ensure proper uid level

MAINTENANCE
NOTICE: Use premium quality hydraulic jack uid. Never use
brake uid, transmission uid, 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.
1. Inspect hoses and connections daily. Replace damaged
components immediately with BVA Hydraulics replacement
parts only.
2. Tighten connections as needed. Use non-hardening pipe
thread compound when servicing connections.
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hoses from
application.
2. With pump in upright, horizontal position, remove the air
vent plug located on the top plate of the reservoir.
3. Use a small funnel to ll reservoir to within 3/4" (19mm) of
the opening.
4. Wipe up any spilled uid and reinstall the air vent plug.
Changing Hydraulic Fluid
1. For best results, change uid once a year.
2. Repeat step 2 on Adding Hydraulic Fluid, then pour used
uid into a sealable container.
3. Dispose of uid in accordance with local regulations.
4. Fill with a good quality hydraulic jack oil as recommended
above. Reinstall air vent plug.
Lubrication
When pump is operated on daily basis, the manufacturer
recommends installing an inline oiler and air dryer. Use SAE
grade oil (5W to 30W).
Storage
1. When not in use, depressurize and disconnect hydraulic
hoses from application.
2. Wipe clean, thoroughly.
3. Store in clean, dry environment. Avoid temperature
extremes.
4. For transportation or long storage, replace the air vent plug
with shipping plug.
5. Shield pump with a protective cover.
