SAFETY
To avoid personal injury or property damage, please follow all safety
precautions. ESCO cannot be responsible for injury or damage resulting from
unsafe and incorrect products use or system operation, or lack of maintenance.
DANGER is only used when your action or lack of action may cause serious injury or even death.
WARNING indicates potential danger that requires correct action to avoid personal injury.
IMPORTANT indicates correct action to prevent damage or equipment failure.
DANGER
The hydraulic equipment operator must be a qualified operator must have correct training and
work experience with hydraulic equipment. Lack of knowledge in any of these areas can lead to
equipment damage or personal injury.
Carefully inspect cylinder, coupler, hose and hand pump before using hydraulic equipment, if you
find any damage, please contact with your nearest Authorized ESCO Service Center or Sales
office. Any damage can cause personal injury when you use the cylinder.
To avoid personal injury, please do not modify or weld hydraulic equipment without approval of
ESCO.
Please never lift a more than the rated capacity of the cylinder, overloading causes equipment
failure and serious personal injury.
The cylinder is a load lifting device, not a load holding device. After the load has been raised or
lowered, it must always be held mechanically, never work under a load supported by a hydraulic
unit.
Keep hands and feet away from cylinder and workplace during operation to avoid personal injury.
NEVER put unbalanced or off-center loads on cylinders. The incorrect load can result in
equipment failure and serious personal injury.
WARNING
Please wear safety glasses, helmet and other necessary personal protective equipment when
operating hydraulic equipment.
NEVER remove the plug or substitute a conventional pipe plug from the piston rod travel
restriction port (See Figure 1).
Load must be lifted on a solid lifting surface like steel or wood.
Please carefully inspect the cylinder and coupler before use. NEVER connect the cylinder with a

damaged coupler or damaged port threads. The damaged coupler or damaged port thread may
cause equipment failure and possible personal injury.
Change the coupler in a clean place; prevent dirt or other debris from getting into the body or
tube. Dirt or other debris will damage the cylinder and result in equipment failure and possible
personal injury.
Before removing or tightening hose or coupler, fully release the hydraulic pressure in the system.
Never handle pressurized hoses; escaping oil under high pressure can puncture the skin and
possibly cause serious injury. Seek medical aid immediately if injured.
Please use ESCO oil or other approved hydraulic oil.
For Hydraulic technical help or repair service, please contact the authorized ESCO Service
Center in your area. ESCO has no obligations under any warranty with respect to products that
have been repaired by unauthorized personnel, modified, or damaged through the misuse,
abuse, accident, neglect, or mishandling.
IMPORTANT
Please keep the cylinder clean at all times.
Keep hydraulic equipment away from flames and heat. Overheating will soften seals and
weaken hose material, resulting in oil leaking or other equipment failure. Do not use
equipment in temperatures of 65c (150f) or higher.
When the cylinder is not in use, please keep the piston rod fully retracted, remove hose
and use rubber cap to cover the coupler.
Please do not drop heavy duty on hose. (tehe)
Before load, please fix a saddle into piston rod, saddle will protect the piston rod.
DESCRIPTION
ESCO Aluminum Lock Nut Cylinders are Single-acting, low weight with a spring return and a stop ring for
stroke restriction. ESCO cylinders are provided with a fully threaded piston rod and a safety lock nut for
positive load holding operations.
CONNECTION
Before using any cylinder, please visually check all units to make sure there is no damage on the
cylinder, port threads, coupler or hose. Check for oil leaks and missing parts. If you find any problems,
please stop immediately and contact your nearest authorized ESCO Service Center or Sales office.
Use a pump with a release valve or 3-way valve and one hose to connect with the lock nut cylinder. After
all parts are connected, please hand-tighten all couplers. If all couplers are not fully tightened, oil will leak
during operation.

OPERATION Figure 2
A B C
4.1 Operate hydraulic pump to advance (see A in figure 2).
4.2 To hold the piston rod, clockwise rotate the Lock nut (see B in figure 2) until reach to the
top of cylinder (see C in figure 2)
4.3 To release the piston rod, Anticlockwise rotate the lock nut until reach to the top of
piston rod
4.4 After finish the work, release the pressure and fully return the piston rod, remove the
hose and cover the coupler by rubber cap.
IMPORTANT: ESCO Lock Nut Cylinder is load return. To reduce the wear and risk, please use
less than the full stroke, and use less than full capacity when possible. Do not allow piston rod to rotate
when installing adapters or during work, rotating piston rod could damage seals.
