Use of additional P.P.E. safety items such as dust mask, 

non-skid safety shoes, hard hat, and hearing protection 

(used as appropriate for the conditions) will reduce the 

chance of personal injuries. The use of these items may also 

be required by local regulations or laws.

•  Do not handle pressurized hoses. Escaping oil under 

pressure can penetrate the skin. If oil is injected under the 

skin, see a doctor immediately.

•  Do not pressurize disconnected couplers.
•  Use hydraulic cylinders only in a coupled system. It is 

acceptable to use a cylinder with a disconnected coupler 

only if the load is mechanically supported by the cylinder 

lock nut, and all hydraulic pressure is completely relieved.

•  When holding loads, be certain that the lock nut is turned 

down firmly against the cylinder base so that the load is 

mechanically supported. Also be sure that all hydraulic 

pressure is completely relieved.

•  Do not remove or disable the pump relief valve.
•  Do not remove or disable the cylinder relief valve (if equipped).
•  The system operating pressure must not exceed the pressure 

rating of the lowest rated component in the system.

•  Install pressure gauge(s) in the system to monitor operating 

pressure. It is your window to see what is happening in the system.

•  Never set a relief valve to a higher pressure than the 

maximum rated pressure of the pump and cylinder. If ratings 

are different, relief valve setting should not exceed the 

setting of the lowest rated component (pump or cylinder).

•  The HCRL-Series cylinders are designed for a maximum 

working pressure of 10150 psi [700 bar]. Do not connect a 

pump with a higher pressure rating to these cylinders.

•  Do not exceed equipment ratings. Never attempt to lift a 

load weighing more than the rated capacity of the cylinder. 

Overloading may cause equipment failure and possible 

personal injury.

•  Be sure setup is stable before lifting load. Cylinders should 

be located on a firm and level surface capable of supporting 

the full load.

•  Where applicable, use a cylinder base plate to provide 

added stability. If desired, the cylinder can be bolted to the 

base plate, using the bolt holes in the bottom of the cylinder 

base.

•  Do not weld, drill or otherwise modify a cylinder to attach a 

base plate or other support unless approved in writing by 

Enerpac Engineering Department. Use only the provided 

bolt holes.

•  Always perform a visual inspection of the cylinder before 

placing it into operation. If any problems are found, do not 

use the cylinder. Have the cylinder repaired and tested 

before it is returned to service.

•  Never use a cylinder that is leaking oil. Do not use a cylinder 

that is damaged, altered or in need of repair.

•  Always lift the cylinder using a hoist, crane or other suitable 

lifting device of sufficient rated capacity. Use only the 

supplied cylinder lifting eyes to attach the cylinder to the 

lifting device. Replace any missing or damaged lifting eyes.

•  Allow only trained and experienced personnel to supervise 

and perform lifting and lowering procedures.

•  Be certain that no persons are working on or near any 

cylinders before lifting or lowering of the load begins. Alert all 

personnel in advance that lifting or lowering is about to occur.

•  Use suitable cribbing of rigid construction to hold loads.
•  Never use a hydraulic cylinder as a shim or spacer in any 

lifting or pressing application.

•  Be certain that the load is centered and covers the entire 

plunger saddle surface. Avoid situations where loads are not 

directly centered on the plunger saddle. The load may slip or 

fall, causing potential danger.

•  Lift only dead weight loads. Avoid lifting live weight loads.
•  Be especially careful when lifting loads such as partially filled 

storage tanks, in which the center of gravity could move or 

shift during lifting. Be aware that the distribution of some 

loads can change quickly and without warning.

•  Do not use the cylinder to lift people. Do not allow people to 

be on top of the load during lifting or lowering.

•  Keep all personnel clear of the work area while lifting or 

lowering is in progress. To avoid personal injury, keep hands 

and feet away from cylinder and load during operation.

•  Maintain communication with the operator at all times during 

lifting or lowering to avoid accidents. Use hand signals, two-

way radios or other appropriate forms of communication (as 

required by applicable laws and regulations) if the load is not 

visible to the operator.

•  Operate pump and valve as required to ensure that the load 

is lifted and lowered evenly and at a controlled rate.

•  Closely watch the load at all times during lifting and lowering. 

Stop lifting or lowering immediately if the load becomes 

unstable or appears to be lifting or lowering unevenly.

•  Stay clear of loads supported only by hydraulics. As required, 

follow the lifted load with cribbing.

•  Never allow persons to work under or near the load while the 

load is being supported hydraulically. After the load has been 

raised or lowered, it always must be blocked mechanically 

by the cylinder lock nut or via suitable cribbing.

•  Always be certain that hydraulic pressure is fully relieved 

and that the load is fully removed from the cylinder(s) before 

disconnecting hydraulic hoses, loosening hydraulic fittings, 

or performing any cylinder disassembly or repair procedures.

  CAUTION

Failure to observe and comply with the following 

precautions could result in minor or moderate personal 

injury. Property damage could also occur.

•  Be careful to avoid damaging hydraulic hoses. Avoid sharp 

bends and kinks when routing hydraulic hoses. Do not 

exceed the minimum bend radius specified by the hose 

manufacturer. Using a bent or kinked hose will cause severe 

back-pressure. Sharp bends and kinks will internally damage 

the hose, leading to premature hose failure.

•  Do not drop heavy objects on hoses. A sharp impact may 

cause internal damage to hose wire strands. Applying 

pressure to a damaged hose may cause it to rupture.

•  Do not lift hydraulic equipment by the hoses or couplers. 

Use the cylinder lifting eyes and appropriately rated lifting 

equipment.

•  Keep hydraulic equipment away from flames and heat. 

Excessive heat will soften packings and seals, resulting in 

fluid leaks. Heat also weakens hose materials and packings.

•  For optimum performance, do not expose hydraulic 

equipment to temperatures of 150˚F [65˚C] or higher. Protect 

all hydraulic equipment from weld spatter.

•  Immediately replace worn or damaged parts with genuine 

Enerpac parts. Enerpac parts are designed to fit properly 

and to withstand high loads. Non-Enerpac parts may break 

or cause the product to malfunction.

 

NOTICE

•  Hydraulic equipment must only be serviced by a qualified 

hydraulic technician. For repair service, contact the Enerpac 

Authorized Service Center in your area.

•  To help ensure proper operation and best performance, use 

of Enerpac oil is strongly recommended.
