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.
