Instruction sheet for ESCO Model #10807
NOTE
PLEASE READ AND FOLLOW THIS INSTRUCTION BEFORE YOU USE ESCO CYLINDERS.
Carefully inspect all components for shipping damage, if shipping damage is found, please notify carrier at
once. The carrier, not ESCO, is responsible for any damage resulting from shipment.
1. 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 use when your action or lack of action may cause serious injury or even death.
WARNING indicates a potential danger that requires correct action to avoid personal injury.
IMPORTANT indicates correct action to prevent damage or equipment failure.
DANGER
The hydraulic equipment user must be a qualified operator familiar with correct training and use of
hydraulic equipment. Lack of knowledge in any of these areas can lead to equipment damage or
personal injury.
Please carefully inspect cylinders, couplers and hose before use hydraulic equipment, if you find any
damage on the couplers, hose, port threads and cylinders, please contact with your nearest
Authorized ESCO Service Center or Sales Office. These damages may cause equipment failure and
possible personal injury.
To avoid personal injury, please do not modify or weld hydraulic equipment without approbated by
ESCO.
Please never lift a load more than the capacity of the cylinders, overloading causes equipment failure
and possible personal injury.
The operating pressure of cylinders are designed for a max pressure of 700 bar (10,000 psi), please
do not use a pump or relief valve with a higher pressure rating to connect the cylinder. Higher pump or
relief valve may cause equipment failure and possible personal injury.
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, please never work under a load supported by hydraulic .
Please keep hands and feet away form cylinder and workplace during operation to avoid personal
injury.
Please do not put poor-balanced or off-center loads on cylinders. The incorrect load can result in
equipment failure and possible personal injury.

WARNING
Please wear safety glasses, safety cap and other necessary personal protective equipment when
operating hydraulic equipment
Use cylinders to lift loads should have solid lifting surface grounded for correct support on. Please
select steel or wood blocks that are capable of supporting the load.
Please install pressure gauges in the system to watch the operating pressure. The gauge must have
the same pressure rating as the pump and cylinder(s). The wrong gauges may result in personal
injury.
Please carefully inspect the cylinders and couplers before use cylinders or shift couplers. Never
connect the cylinders with damaged couplers or damaged port threads. The damaged coupler or
damaged port threads may cause equipment failure and possible personal injury.
Please shift couplers in a clean environment, prevent dust or other garbage into cylinder body or tube.
Dust or other garbage will damage the cylinder and result in equipment failure and possible personal
injury.
Cylinder must be placed on a stable base, please use ESCO cylinder base to improve stability.
Before removing or tightening hose or couplers, please release hydraulic pressure in system.
To seek hydraulic technical helps or repair service. Please contact the authorized ESCO Service
Center in your area. ESCO is not responsible for any injury and property damage. If you repair your
equipment in other hydraulic service centers which dose not authorized by ESCO.
Hydraulic cylinders must use special hydraulic oil or other approved hydraulic oil.
IMPORTANT
Please keep the cylinder clean all the time.
When the cylinder is not in use, please keep the piston rod fully return, remove hose and use rubber
cap to recover the coupler(s). If you use collar threads, please use the thread protector to recover the
collar threads.
Please do not drop heavy duty on hose.
Please do not lift and carry hydraulic cylinders by the hoses or couplers, use the handle or other safe
way.
Please use hydraulic equipment in normal temperature, do not use equipment in temperatures of
65 ℃ (150 ℉ ) or higher. Overheating will soften seals and weakens hose materials, resulting in oil
leaking or other equipment failure.
Before load, Please fix a saddle into piston rod. Saddle will protect the piston rod.
OPERATION
Before use cylinder, please visually check all units, to make sure there are no damage on cylinder, port
threads, couplers and hose. No oil leaking and shortage of parts. If you find any problem please contact
with your nearest authorized ESCO Service Center or Sales office.
2.1 Connection
Single Acting Cylinders
Please use a pump with a release valve or a 3-way valve and one hose to connect with Single Acting
Cylinder (Figure 1). After connected all parts, please fully hand-tighten all couplers. If not, oil will be
leaked between the pump and cylinder.

Double Acting Cylinders
Please use a pump with a 4-way valve and two hoses to connect with Double Acting Cylinder. After
connected all parts, please fully hand-tighten all couplers. If not, oil will be leaked between the pump and
cylinder.
Note: Double-acting cylinders must have both couplers connected and every coupler must be fully
hand-tightened
Figure 1 Figure 2
2.2 Bleeding Air from the cylinder
Air may accumulate within a cylinder during shipment or after prolonged use; this air can cause the piston
rod to respond “dithering.” Please follow the steps below to bleed the air from cylinder.
Single-acting cylinders:
Position the cylinder as figure 3 shows, so that the
piston rod is extended down and the cylinder lower
than the pump. Fully extend and retract the cylinder 1
or 2 times. It may be necessary to repeat the above
steps several times.
Double-acting cylinders:
Lay the cylinder as figure 4 shows, to make sure the
couplers facing up. Fully extend and retract the
cylinder1 or 2 times. It may be necessary to repeat
the above steps several times.
2.3 For single acting cylinders, please do not allow piston rod to rotate when installing adaptors or during
the work. Rotating piston rod may damage the return spring.
3. MAINTENANCE
3.1 Please always use clean oil or other approved hydraulic oil with these cylinders. Use other unapproved
oil or dirty oil will damage the cylinders.
3.2 Always keep cylinder clean, use thread protector and dust cap to protect collar thread and couplers.
3.3 After finish work, Cylinder must be fully retracted, cleaned and stored in ventilation, moist-proof,
corrosion-proof place.
