Hydraulic Hoses and Fluid 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. Before operating
the pump, all hose connections must be tightened
with the proper tools. Do not overtighten. Connections
should only be tightened securely and leak-free.
Overtightening can cause premature thread failure or
high pressure fittings to burst.
• 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.
• 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 appropriate
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.
IMPORTANT
• Keep ram clean at all times.
• When the ram is not is 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
manufacturer.
• Never use other than factory provided and/or
authorized fasteners.
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 your nearest Porto-Power Blackhawk
Automotive Dealer.
