Application responds slower than
normal
• Loose connection or coupler
• Restricted hydraulic line or fitting

• Clean and replace if damaged
• Replace application/connection
Application does not return fluid to
pump (i.e. cylinder will not retract)

plication
•
Secure load by other means

remove application, then drain fluid to
proper level
•
Secure load by other means
.
Depressurize
pump and hose,

• Ensure proper fluid level
MAINTENANCE
NOTICE:
Use only a good quality hydraulic jack fluid. 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.
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.
3. Use only good quality hydraulic fluid. We recommend BVA
FJZ01 or equivalent.
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 fill reservoir to within 3/4" (19mm) of
the opening.
4. Wipe up any spilled fluid and reinstall the air vent plug.
Changing Hydraulic Fluid
1. For best results, change fluid once a year.
2. Repeat step 2 on Adding Hydraulic Fluid, then pour used
fluid into a sealable container.
3. Dispose of fluid 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.
