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 qualied 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.
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 qualied, 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.

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. Inspect before each use. Do not use if bent, broken,
leaking or damaged components are noted.
3. Check to ensure that all parts of your kit are included
(see illustration and parts list).
4. Carefully remove the dust caps and plugs from hose
coupler and ram coupler.
5. Connect hose coupler to ram coupler, ensure that
there are no uid leaks.
6. Locate and open release valve. Close release
valve clockwise and pump handle until ram is fully
extended, then open release valve counter-clockwise
until ram has fully retracted.
7. With ram fully retracted and release valve open,
place pump in horizontal position. Open oil ller
screw (on reservoir body, near the back). This will
release air trapped within the reservoir. Re-tighten
the oil ller screw.
8. If using with air actuated units, an air source of at
least 7.8 CFM @ 110 psi is required.
GENERAL SAFETY INFORMATION
1. Ensure that attachments are fully engaged before
applying load.
2. Ensure that load is centrally applied to attachment or
ram saddle. Do not load off center.
3.
Always monitor the force applied to workpiece by
using a load cell and indicator or you may monitor
pressure developed in the ram by using an inline
pressure gauge, then calculate the applied force
using the formula:
F = P x A, where F = lb force, P = pressure in psi,
and A = effective ram area in in2.
Ram Area of Model 4M04T is: 0.998 in2
Ram Area of Model 4M10T is: 2.411 in2
Refer to Load-Pressure correlation chart on page 11.
If bowing or bending of ram or any attachment occurs
during use, "STOP", release pressure immediately
and reconsider application. Application may not
be compatible with product, a ram kit with a higher
capacity may be needed.
Figure 2 - Horizontal and Vertical position
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.
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 a good grade hydraulic oil. Avoid mixing
different types of uid and Never use brake uid,
turbine oil, transmission uid, motor oil or glycerin.
Improper uid can cause premature failure of the
ram and the potential for sudden and immediate
loss of load. We recommend Hein-Werner 8H1G
or equivalent.
Adding 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.
Changing 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
suitable 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.

Load - Pressure Correlation For Model 4M04T & 4M10T
Always monitor the force applied to workpiece by using a load cell and indicator or you may monitor pressure
developed in the ram by using an inline pressure gauge, then calculate the applied force using the formula:
F = P x A
For model 4M04T, A = 0.998 in² ;
For model B55115, A = 2.411 in²
Example1
Model 4M04T lifting 5,000 lb will require what
presure?
Pressure = 5,000 lb / 0.998 in² = 5,010 psi
where F = Force/ Load (lb);
P = Hydraulic working pressure (psi) and;
A = Ram effective area (in²)
Example2
Model 4M10T operating at 6,000 psi will generate
what force?
Force = 6,000 psi x 2.411 in2= 14,466 lb
