MAINTENANCE
Important: 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.
We recommend Mobil DTE 13M or equivalent.
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 Mobil
DTE 13M or equivalent.
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hose 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.

OPERATION
To reduce the risk of personal injury and/or property
damage, hydraulic connections must be securely fastened
before building pressure in the system. Release all system
pressure before loosening any hydraulic connection in the
system.
Always monitor pressure, load or position using
suitable equipment. Pressure may be monitored by means of
an optional manifold and gauge. Load may be monitored by
means of a load cell and digital indicator. Correct application
position can only be determined by the operator of the
equipment.
1. Air connection: Remove plug from first or second air input
port (refer to figure 1) and connect to adequate air supply.
Install hex plug on unused air input port to prevent air
leakage.
2. Hydraulic connection: Remove manifold plug from oil
output port and connect to suitable application using 3/8
NPT connection.
3. To operate pump, press and hold on the advance button of
the remote control until desired pressure, load or position
is reached. Always monitor pressure, load or position
using suitable equipment. Pressure may be monitored by
means of an optional manifold and gauge (contact BVA
Hydraulics). Load may be monitored by means of a load
cell and digital indicator. Correct application position can
only be determined by the operator of the equipment.
4. To retract application, simply press the retract button on
the remote control.
Note: Both air input ports use a 1/4 NPT air nipple (not
included). It is recommended to install an inline air filter and
dryer upstream from the pump to provide clean, lubricated air.
