! WARNING

Failure to comply with the following warnings

may

result in personal injury as well as

property damage.

•

Study, understand, and follow all instructions

provided with and on this device before use.

• The user must be a qualied operator familiar

with the correct operation, maintenance, and use of

cylinders.

Wear protective gear when

operating hydraulic equipment.

This device is NOT suitable for use as support

device! As the load is lifted, use blocking and

cribbing to guard against a falling load.

Stay

clear of a lifted load before it is properly

supported

Never rely on hydraulic pressure to support a load.

Crush Hazard. Keep hands and feet

away from cylinder and workpiece

during operation.

•

Do not exceed rated capacity of the cylinder or

any equipment in the system. The cylinder is

designed for a max. pressure of 10,000 psi.

•

Do not connect a cylinder to a pump with higher

pressure rating.

• Do not subject cylinder to a shock loads, a load

dropped suddenly, causing the system pressure to

exceed rated pressure.

The system operating pressure must not exceed

the pressure rating of the lowest rated component

the system. Install a pressure gauge or other load

measuring instrument to monitor the operating pressure. Burst

hazard exists if hose, connection or any other component in

the system exceed its rated pressure.

Avoid damaging hydraulic hose. Do not allow

hose to kink, twist, curl, crush, cut or bend so

tightly that uid ow within the hose is blocked or

reduced. Periodically inspect the hose for wear.

Do not pull, position or move cylinder setup by

the hose. Use carrying handle or other means

of safe transport.

Do not handle pressurized hoses. Never attempt

to grasp a leaking pressurized hose. Ensure to

release the system pressure before disconnecting

hydraulic hose or connections.

Hydraulic uid can ignite and burn. Keep

hydraulic equipment away from ames and

heat.

Excessive heat will soften seals, resulting in

uid leaks. Heat also weakens hose materials.

Cylinder must be on a stable base which is able

to support the load while pushing or lifting. Use

shims, friction material or constrains to prevent

slippage of the base or load. Ensure cylinder is fully engaged

into/onto adapters, extension accessories.

Center load on cylinder. Distribute load evenly

across the entire saddle surface. Do not

off-center loads on a cylinder. The load can tip

or the cylinder can “kick out”.

Never try to disassemble a hydraulic cylinder,

refer repairs to qualied, authorized personal.

Contact BVA Hydraulics tech service for authorized

service center.

Do not subject hose to sharp objects or

heavy impact.

Hose material or seals must not come in

contact with corrosive materials such as

battery acid, creosote-impregnated objects

and wet paint. Never paint a coupler or hose.

•

No alteration shall be made to the cylinder.

•

Use only factory authorized fasteners,

accessories and hydraulic uid.

Heavy

INSTALLATION

IMPORTANT! Use an approved, high-grade pipe sealant to

seal all hydraulic connections.

Remove the dust cover and rubber plug from coupler

2. Inspect all threads and ttings for signs of wear or damage,

and replace as needed. Clean all threads and ttings.

3. Connect hydraulic hose from hydraulic pump to the cylinder

coupler. Ensure that there are no uid leaks.

4. Install in-line pressure gauge.

5. Check for leaks in system and have repaired by qualied

personnel.

Note: The use of cylinder attachments or extensions reduces

the cylinder capacity by at least 50% per attachment/

extension.

Before operating the pump, tighten all hose

connections with proper tools. Do not overtighten.

Connections should only be tightened securely and leak-

free. Overtightening can cause premature thread failure or

high pressure ttings to burst.

Before repairs are made, depressurize cylinder.

Tips for hydraulic hoses & uid transmission lines:

• Avoid short runs of straight line tubing. Straight line runs

do not provide for expansion and contraction due to

pressure and/or temperature changes.

• Reduce stress in tube lines. Long tubing runs should be

supported by brackets or clips.
