Failure to comply with the following warnings may
result in personal injury as well as property
damage.
• Study, understand, and follow all instructions
provided with and on this device before use.
• Theusermustbeaqualiedoperatorfamiliarwith
the correct operation, maintenance, and use of cylinders.
Wear protective gear when operating
hydraulicequipment.
This device is NOT suitable for use as support
device! As the load is lifted, use blocking and cribbing
to guard against a falling load. Stay clear of a lifted
load before it is properly supported. Never rely on
hydraulic pressure to support a load.
Crush Hazard. Keep hands and feet away
from cylinder and workpiece during
operation.
• Do not exceed rated capacity of the cylinder or
any equipment in the system.The cylinder is
designed for a max. pressure of 10,000 psi.
•Do not connect a cylinder to a pump with higher pressure rating.
•Do not subject cylinder to a shock loads, a load dropped
suddenly, causing the system pressure to exceed rated
pressure.
Thesystemoperatingpressuremustnotexceedthe
pressure rating of the lowest rated component
the system. Install a pressure gauge or other load
measuring instrument to monitor the operating pressure. Burst
hazard exists if hose, connection or any other component in the
system exceed its rated pressure.
Avoid damaging hydraulic hose. Do not allow hose
to kink, twist, curl, crush, cut or bend so tightly that
uid ow within the hose is blocked or reduced.
Periodically inspect the hose for wear.
Do not pull, position or move cylinder setup by the
hose. Use carrying handle or other means of safe
transport.
Do not handle pressurized hoses. Never attempt to
grasp a leaking pressurized hose. Ensure to release
the system pressure before disconnecting hydraulic
hose or connections.
Hydraulic uid can ignite and burn. Keep
hydraulic
equipment away from ames and heat.
Excessive
heat will soften seals, resulting in uid leaks. Heat
also weakens hose materials.
Cylinder must be on a stable base which is able
to support the load while pushing or lifting. Use shims,
friction material or constrains to prevent slippage
of the base or load. Ensure cylinder is fully engaged
into/onto adapters, extension accessories.
Center load on cylinder. Distribute load evenly across
the entire saddle surface. Do not off-center loads on
a cylinder.The load can tip or the cylinder can
“kick out”.
Never try to disassemble a hydraulic cylinder, refer
repairstoqualied,authorizedpersonal.ContactWilliams
tech service for authorized service center.
Do not subject hose to sharp objects or heavy
impact.
Hose material or seals must not come in contact with
corrosive materials such as battery acid, creosote-
impregnated objects and wet paint. Never paint a
coupler or hose.
•
No alteration shall be made to the cylinder.
•
Use only factory authorized fasteners, accessories
andhydraulicuid.

INSTALLATION
NOTICE: Use an approved, high-grade pipe sealant to seal all
hydraulic connections.
1.
Remove the dust cover and rubber plug from coupler
.
2. Inspectallthreadsandttingsforsignsofwearordamage,and
replaceasneeded.Cleanallthreadsandttings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler.Ensurethattherearenouidleaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
NOTICE: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/extension.
WARNING: Before operating the pump, tighten all hose
connections with proper tools. Do not overtighten. Connections
should only be tightened securely and leak-free. Overtightening can
cause premature thread failure or high pressure ttings to burst.
WARNING: Before repairs are made, depressurize cylinder.
Tipsforhydraulichoses&uidtransmissionlines:
•Avoidshortrunsofstraightlinetubing.Straightlinerunsdonot
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.

OPERATION
Operate the hydraulic pump to advance and retract the cylinder.
Do not continue pumping when cylinder is fully extended. Internal
pressure will build up and may damage the seal of the cylinder.
WARNING: NEVER rely on hydraulic pressure alone to
secure a load! NEVER allow personnel to work or pass under
a load until the load is secured by cribbing, blocking, or other
mechanical means.
WARNING: To help prevent material fatigue if the cylinder
is to be used in a continuous application, the load should not
exceed 85% of the rated capacity.
WARNING:
Your cylinder, hose(s), couplings and pump all must
be rated for the same maximum operating pressure, correctly
connected and compatible with the hydraulic uid used. An
improperly matched system can cause the system to fail.
WARNING: All personnel must be clear before lowering load.
MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged
components immediately with Williams Replacement Parts only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3. Always use clean, approved hydraulic uid and change as
recommended or sooner if the uid becomes contaminated
(never exceed 400 hours). Follow pump manufacturers
instructionsforchangingandaddinghydraulicuid.Useonly
goodqualityhydraulicuid.WerecommendMobilDTE13Mor
equivalent when using with hand pump or air pump; Williams
Oil (F01) or equivalent when using with electric pump. Never
usebrakeuid,transmissionuid,turbineoil,motoroil,alcohol,
glycerin etc. Use of other than good quality hydraulic oil will void
warranty and damage the cylinder, pump, hose etc.
4. Use an approved, high-grade pipe thread sealant to seal all
hydraulicconnections.Teontapecanbeusedifonlyonelayer
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
owofuidandadverselyaffectfunction.
Lubrication & Cleaning
Keep cylinder clean at all times.
1. Any exposed threads (male or female) must be cleaned and
lubricated regularly, and protected from damage. Lubricate with
light machine oil.
2. If a cylinder or ram has been exposed to rain, snow, sand,
airborne abrasive, or any corrosive environment, it must be
cleaned, lubricated, and protected immediately after exposure.
Dailycleanexposedramwithcleanclothdampenedwithlight
machine oil. Protect exposed ram from the elements at all times.
3. Keep the hydraulic system as free of dirt as possible. When
not in use, couplers must be sealed with dust covers. All hose
connections must be free of dirt and grime. Any equipment
attached to the cylinder must be kept clean.
Storage
Cylinders should be stored vertically with ram plunger fully retracted
in a dry, protected area, not exposed to corrosive vapor, dust or
other harmful elements. When a cylinder has not been used for
a period of 4 months, it should be connected to a pump and fully
extended and then retracted a minimum of 5 times. This cycle will
lubricate the cylinder wall, reducing the possibility of corrosion and
damage thereof.
How to remove faulty coupler:
If cylinder does not retract,
1. Secure load by other means.
2. Depressurizepumpandhose.
3. Remove the cylinder from application.
4. Disconnectandreplacewithnewcoupler.
