PRODUCT DESCRIPTION
Williams Single Acting Cylinder is designed for rated
capacity pushing, spreading and pressing jobs. A wide
variety of applications exist for this category of product.
Special skill, knowledge and training may be required for
a specic task and the product may not be suitable for all
the jobs described above.
NEVER use hydraulic cylinder as a support device!
Always check connections before using. Alteration of these
products is strictly prohibited. Use only those adapters and
attachments provided and approved by the manufacturer.
WARNING: To reduce the risk of personal injury and/
or property damage, ensure that the rated working pressure of
each pressurized attachment be equal to or greater than the rated
working pressure developed by the hydraulic pump.
Unsuitable applications would include applications that call for
a device to move, level or support persons, animals, hazardous
materials, mobile homes/dwellings in general, mirrors and/or plate
glass, and/or to connect/secure hatches, components, etc. between
bulkheads. The user ultimately must make the decision regarding
suitability of the product for any given task and therefore accept
responsibility for that decision. Immediately after lifting, loads must
be supported by appropriate mechanical means.

!WARNING
• Study, understand, and follow all instructions
provided with and on this device before use.
• The user must be a qualied operator familiar
with the correct operation, maintenance, and use of
cylinders.
Wear personal protective
equipment when operating
hydraulic equipment.
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.
The system operating pressure must not exceed
the 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 repairs to qualied, authorized personal.
Contact Williams tech service.
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.
Heavy
INSTALLATION
IMPORTANT! Use an approved, high-grade pipe sealant to
seal all hydraulic connections.
1.
Remove the dust cover and rubber plug from coupler .
2. Inspect all threads and ttings for signs of wear or damage,
and replace as needed. Clean all threads and ttings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no uid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualied
personnel.
Note: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/
extension.
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.
Before repairs are made, depressurize cylinder.
Tips for hydraulic hoses & uid 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.
!
!
Failure to heed these and all warning, safety
messages provided with and on this device may
result in personal injury as well as
property damage.
No alteration shall be made to the cylinder.
Use only factory authorized fasteners,
accessories and hydraulic uid.

BEFORE USE
1. Before using this product, read the owner's manual
completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards
associated with its use.
2. Verify that the product and the application are compatible.
If in doubt, contact tech service @ [phone].
3. Inspect before each use. Do not use if bent, broken, leaking
or damaged components are noted.
4. Replace worn or damaged parts and assemblies with
Williams authorized replacement parts only. Lubricate as
instructed in Maintenance Section.
5. Ensure method of conrming load is accurate and working
properly. Have gauge or load cell accuracy veried by
qualied personnel on a yearly basis.
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.
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.
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.
All personnel must be clear before lowering load.
MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged
components immediately with Williams authorized
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
instructions for changing and adding hydraulic uid. Use
only good quality hydraulic uid. We recommend Mobil
DTE13M or equivalent when using with hand pump or air
pump; DTE 15Ml or equivalent when using with electric
pump. Never use brake uid, transmission uid, turbine
oil, motor oil, 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
hydraulic connections. Teon 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 ow of uid and adversely affect function.
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. Daily clean exposed ram with clean cloth
dampened with light 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. Depressurize pump and hose.
3. Remove the cylinder from application.
4. Disconnect and replace with new coupler.
Important: Do not attempt to grasp with pliers or wrench
without rst wrapping the jaws of such tool with rags or
similar padding.
How to bleed air from system:
1. Place pump at a higher elevation than the hose and
cylinder as shown in gure 2 below.
2. Operate pump to fully extend and retract the cylinder 2 or
3 times. The objective is to force the air bubbles up hill
and back to the pump reservoir.
3. Follow pump instruction manual to bleed the air from
pump reservoir. On most pumps, air can escape by
opening the oil ller plug/screw.
