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 qualified operator familiar
with the correct operation, maintenance, and
use of rams.
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 ram and workpiece during
operation.
• Do not exceed rated capacity of the ram or any
equipment in the system. The ram is designed for
a max. pressure of 10,000 psi.
• Do not connect a ram to a pump with higher
pressure rating.
• Do not subject ram 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
fluid flow within the hose is blocked or reduced.
Periodically inspect the hose for wear.

Do not pull, position or move ram 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.
Ram 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 ram is
fully engaged into/onto adapters, extension
Center load on ram. Distribute load evenly across
the entire saddle surface. Do not off-center loads
on a ram. The load can tip or the ram can "kick out".
Never try to disassemble a hydraulic ram, refer
repairs to qualified, authorized personal. Contact
Williams 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 ram.
• Use only factory authorized fasteners, accessories
and hydraulic fluid.
