Williams Hydraulic Spreaders are designed for rated capacity
pushing and spreading. A wide variety of applications exist
for this category of product.
Special skill, knowledge and training may be required for
a specic task and the product may not be suitable for all
the jobs described above. 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.
PRODUCT DESCRIPTION
NEVER rely upon a hydraulic spreader as a support
device! Immediately after lifting, loads must be
supported by appropriate mechanical means.
Always check connections before using. Alteration
of these products is strictly prohibited. Use only
those adapters and attachments provided and approved
by the manufacturer.
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.

GENERAL SAFETY INFORMATION
1. Ensure that both spreader jaws fully engage the load
and that the load is centered on the serrated portion of
each spreader jaw before pressurizing spreader. Do not
load off center.
2.
Always monitor the hyraulic pressure pressure developed
in the spreader ram by using an inline pressure gauge.
These spreaders are designed to develop 10,000 psi
at rated capacity.
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.

Do not pull, position or move ram 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.
Ram 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 ram is
fully engaged into/onto adapters, extension
accessories.
Center load on ram. Distribute load evenly across
the entire saddle surface. Do not off-center loads
on a ram. The load can tip or the ram can “kick out”.
Never try to disassemble a hydraulic ram, refer
repairs to qualied, authorized personal. Contact
Williams 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 ram.
•
Use only factory authorized fasteners, accessories
and hydraulic uid.
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.
• The user must be a qualied operator familiar
with the correct operation, maintenance, and
use of rams.
Wear protective gear 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 ram and workpiece during
operation.
•
Do not exceed rated capacity of the ram or
any
equipment in the system. The ram is
designed for
a max. pressure of 10,000 psi.
•
Do not connect a ram to a pump with higher pressure rating.
• Do not subject ram 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.

OPERATION
ALWAYS monitor pressure, load or position using
suitable equipment. Pressure may be monitored by means
of an optional manifold and gauge. Load may be monitored
by means of a load cell and digital indicator.
Note: Any attachment that is not loaded centrally, as through
the centerline of the ram, is considered to be “offset”.
When
extension tubes and/or offset attachments are used, the
rated capacity is always reduced by 50% for each tube or
offset attachment connected.
1. Pump may be used in horizontal and vertical position as
illustrated on gure 2 below.
Changing Hydraulic Oil
For best performance and increased system life, replace the
complete uid supply at least once per year.
1. With ram fully lowered, remove the oil ller screw from the
pump reservoir as above.
2. Lay the pump on its side and drain the uid into a suit-
able container.
Note: Dispose of hydraulic uid in accordance with local
regulations.
3. Set pump in its level upright position.
4. Fill with good quality jack oil to within 3/8" of the oil ller
screw hole opening. Reinstall oil ller screw.
Lubrication
A coating of light lubricating oil to pivot points and hinges
will help to prevent rust and assure that pump assemblies
move freely.
Cleaning
Periodically check the pump piston and ram for signs of rust
or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sandpaper or abrasive material on these
surfaces!
Storage
When not in use, store with the pump piston and ram fully
retracted.
How to remove faulty coupler:
If ram does not retract,:
1. Secure load by other means.
2. Depressurize pump and hose
3. Remove the ram from application.
4. Disconnect and replace with new coupler.
Important: Do not attempt to grasp ram 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 ram
as shown in gure 3 below.
2. Operate pump to fully extend and retract the ram 2 or 3
times. The objective is to force the air bubbles up hill and
back to the pump reservoir.
3. To bleed the air from pump reservoir, simply open the oil
ller screw. Re-install after bleeding.
!
2. Locate and close release valve by turning it clockwise until
rmly closed. (Do not over tighten)
3. Operate by pumping handle. This will send uid from the
pump reservoir into the high pressure hose assembly and
into the ram assembly.
4. Continue pumping until ram reaches desired position.
NEVER operate pump with release valve closed and
disconnected from application. If operated in this condition,
the hose and connections become pressurized. This
increases burst hazard. Damage may occur to pump and
its components.
5. To Release Pressure on work piece: Slowly, carefully turn
the release valve counter-clockwise until ram retracts
to desired position. Never turn release valve more than
1/2 full turn. The ram return system is spring loaded and
the release valve system is metered, allowing controlled
retraction of the ram.
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. Use only good quality hydraulic uid. We recommend
Williams 8H1G or equivalent. 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 pump, hose, and application.
Adding Hydraulic Oil
1. With ram fully lowered, set pump unit in its normal, level
position. Locate and remove oil ller screw.
2. Fill until oil is within 3/8" of the oil ller screw hole opening,
re-install oil ller screw.
