WARNING
• Should a hydraulic hose ever rupture, burst or
need to be disconnected, immediately shut off the
pump and release all pressure. Never attempt to
grasp a leaking pressurized hose with your
hands. The force of escaping hydraulic fluid can
inflict injury.
• Do not subject the hose to potential hazard such
as fire, sharp objects, extreme heat or cold, or
heavy impact.
• Do not allow the hose to kink, twist, curl, crush,
cut or bend so tightly that the fluid flow within the
hose is blocked or reduced. Periodically inspect
the hose for wear, because any of these
conditions can damage the hose and possibly
result in personal injury.
• Do not pull, position or move setup by the hose.
Doing so can damage the hose and possibly
cause personal injury.
• Hose material and coupler seals must be
compatible with hydraulic fluid used. Hoses also
must not come in contact with corrosive materials
such as battery acid, creosote-impregnated
objects and wet paint. Hose deterioration due to
corrosive material can result in personal injury.
Never paint a coupler or hose.
• The user must be a qualified operator familiar with
the correct operation, maintenance, and use of
rams. Lack of knowledge in any of these areas
can lead to personal injury.
• Use only approved accessories and approved
hydraulic fluid.
• Do not exceed the rated capacity of the ram.
• Inspect each ram and coupler before each use to
prevent unsafe conditions from developing.
• Do not use rams if they are damaged, altered or
in poor condition.
• Do not use rams with bent or damaged coupler or
damaged threads.
• Under certain conditions, the use of an extension
with a hydraulic ram may not be advisable and
could present a dangerous condition.
• Avoid pinch points or crush points that can be
created by the load or parts of ram.
• To help prevent material fatigue if the ram is to
be used in a continuous application, the load
should not exceed 85% of the rated capacity.
• Ram must be on a stable base which is able
to support the load while pushing or lifting.
SAFETY INSTRUCTIONS (cont.)

WARNING
• Ensure ram is fully engaged into/onto adapters,
extension accessories.
• To help prevent personal injury, use shims, friction
material or constraints to prevent slippage of the
base or load.
• Do not off-center loads on a ram. The load can tip
or the ram can "kick out" and cause personal
injury.
• As the load is lifted, use blocking and cribbing to
guard against a falling load.
• Never allow personnel to work on, under or around
a load before it is properly supported by appropri-
ate mechanical means. Never rely on hydraulic
pressure alone to support load.
• All personnel must be clear before lowering.
• Never try to disassemble a hydraulic cylinder,
Refer repairs to qualified, authorized personnel.
Center loads on ram
IMPORTANT
• Keep ram clean at all times.
• When the ram is not in use, keep the piston(s)
fully retracted.
• Use an approved, high-grade pipe thread sealant
to seal all hydraulic connections. Teflon tape can
be used if only one layer of tape is used and it is
applied carefully (two threads back) to prevent the
tape from being introduced into hydraulic system.
A piece of tape could travel through the system
and obstruct the flow of fluid and adversely affect
function.
• Never attach ANY component not authorized by
Sears.
KNOW YOUR SYSTEM
Your ram, hose(s), couplings and pump all must be
rated for the same maximum operating pressure,
correctly connected and compatible with the
hydraulic fluid used. An improperly matched system
can cause the system to fail and possibly cause
serious injury. If you are in doubt, consult Sears.
