SAFETY INSTRUCTIONS (cont.)
© Sears, Roebuck and Co.4
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 xA, where F = lbs force, P = pressure in PSI, andA = effective ram area in in².
RamArea of 50364 is: 0.998 in²
RamArea of 50347 is: 2.431 in²
4. 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.
• If oil leakage is detected, discontinue use of the
ram immediately and contact your nearest Sears.
Theramcould develop excessive pressureand
cause the ram, hose or coupler to burst which
could cause serious injury or death.
• When loading a ram, always insure that coupler,
port, and adapter threads have not been dam-
aged. Failure to do so could cause serious injury
or death.
• Avoid off-center loads. Loading off center may
damage the ram and cause loss of load which
may cause serious injury or death.
• Control the load at all times. Do not drop the
load. Threads may shear and cause loss of the
load, which may cause serious injury or death.
•All WARNINGstatements mustbecarefullyobserved
tohelp prevent personalinjury.
•Do not exceed rated capacity.
• Use only on hard, level surfaces capable of
sustaining rated capacity loads.
•Do not open oil filler screw unless ram is fully
retracted.
•Wear protective clothing and safety goggles to
reduce the risk of injection.
•Do not wear sandals and jewelry when operating
thisequipment.
•Do not use as a vehicle lifting device or as a
vehiclesupport.
•When extension tubes and/or offset attachments
are used, the rated capacity is always reduced by
50% for each tube or attachment connected.
•Any attachment that is not loaded centrally, as
through the centerline of the ram, is considered to
be "offset". See parts section for identification of
offsetatachments.
• Monitor pressure and load at all times.
• Always verify load with calibrated load cell and
indicator,known good pressuregaugeor equivalent
devices.
•Do not modify this device.
•Failure to heed these markings may result in
personalinjury and/or propertydamage.
Hydraulic Hoses and Fluid Transmission Lines
• Avoid short runs of straight line tubing. Straight
lineruns do notprovide 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. Before
operating the pump, all hose connections must be
tightened with the proper tools. Do not overtighten.
Connections should only be tightened securely
andleak-free.Overtighteningcancausepremature
thread failure or high pressure fittings to burst.
! DANGER !
Toavoidcrushingand
relatedinjuries:
NEVERworkon, under
oraround a load
supported only by ram.
ALWAYS use
adequatelymechanical
support such as rated
jack stands.

!
• Should a hydraulic hose ever rupture, burst or
need to be disconnected, immediately shut off the
pump and release all pressure. Never attempt to
grasp a leaking pressurized hose with your
hands.The forceofescaping hydraulic fluidcan
inflict injury.
•Do not subject the hose to potential hazard such
as fire, sharp objects, extreme heat or cold, or
heavyimpact.
•Do not allow the hose to kink, twist, curl, crush,
cut or bend so tightly that the fluid flow within the
hose is blocked or reduced. Periodically inspect
the hose for wear, because any of these
conditions can damage the hose and possibly
result in personal injury.
•Do not pull, position or move setup by the hose.
Doing so can damage the hose and possibly
causepersonal injury.
•Hose material and coupler seals must be
compatible with hydraulic fluid used. Hoses also
must not come in contact with corrosive materials
suchas battery acid,creosote-impregnated
objects and wet paint. Hose deterioration due to
corrosive material can result in personal injury.
Neverpainta coupler or hose.
•Theusermust be a qualified operatorfamiliar with
thecorrect operation, maintenance, anduseof
rams. Lack of knowledge in any of these areas
can lead to personal injury.
•Useonlyapprovedaccessoriesandapproved
hydraulicfluid.
•Do not exceed the rated capacity of the ram.
•Inspect each ram and coupler before each use to
preventunsafeconditions from developing.
•Do not use rams if they are damaged, altered or
inpoor condition.
•Do not use rams with bent or damaged coupler or
damagedthreads.
•Under certain conditions, the use of an extension
with a hydraulic ram may not be advisable and
couldpresent a dangerouscondition.
•Avoid pinch points or crush points that can be
created by the load or parts of ram.
•To help prevent material fatigue if the ram is to
be used in a continuous application, the load
should not exceed 85% of the rated capacity.
•Ram must be on a stable base which is able
to support the load while pushing or lifting.
•Ensure ram is fully engaged into/onto adapters,
extension accessories.
•Tohelp prevent personalinjury, useshims,friction
materialor constraints topreventslippage of the
base or load.
•Do not off-center loads on a ram. The load can tip
or the ram can "kick out" and cause personal
injury.
•As the load is lifted, use blocking and cribbing to
guardagainsta falling load.
•Neverallowpersonnel to work on, underor around
a load before it is properly supported by appropri-
ate mechanical means. Never rely on hydraulic
pressurealoneto support load.
•Allpersonnel must beclearbefore lowering.
•Never try to disassemble a hydraulic cylinder,
Referrepairstoqualified,authorizedpersonnel.
IMPORTANT
•Keep ram clean at all times.
•When the ram is not in use, keep the piston(s)
fullyretracted.
•Useanapproved, high-grade pipe threadsealant
to seal all hydraulic connections. Teflon 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
andobstructthe flow of fluidand adverselyaffect
function.
•Never attach ANY component not authorized by
Sears.
KNOW YOUR SYSTEM
Your ram, hose(s), couplings and pump all must be
ratedforthesame maximum operating pressure,
correctly connected and compatible with the
hydraulic fluid used.An improperly matched system
can cause the system to fail and possibly cause
serious injury. If you are in doubt, consult Sears.

Note: Inspectbefore each usefor evidenceoffluid leaks, damagedhydraulic fittings,bentor broken attach-
ments and missing parts.
1. Locate and close release valve by turning it clockwise until firmly closed. (Do not over tighten)
2. Operate by pumping handle. This will send fluid from the pump reservoir into the high pressure hose assembly
and into the ram assembly.
3.Continue pumping untilramreaches desired height.
Note: Pump may be used in horizontal and vertical position as illustrated (See figure 2).
OPERATION
To Release Pressure on work piece:
Slowly, carefully turn the release valve counterclockwise until ram retracts to desired position. Never turn
release valve more than 1/2 full turn. The ram return system is spring loaded, allowing controlled retraction
ofthe ram.
Figure 2 - Horizontal and Vertical Position
MAINTENANCE
Important: Use only a good grade hydraulic oil. We recommend Mobil DTE13M.Avoid mixing different types of
fluid andNever use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause
failure of the pump and the potential for sudden and immediate loss of load.
Adding oil
1. With ram fully lowered, set pump unit in its normal, level position. Locate and remove oil filler screw (see
Figure1).
2. Fill until oil is within 3/8" (6 mm) of the hole opening, reinstall oil filler screw.
Changing oil
For best performance and increased system life, replace the complete fluid supply at least once per year.
1.Withram fully lowered,remove theoil fillerscrew fromthepumpreservoir as above.
2. Lay the pump on its side and drain the fluid into a suitable container.
Note: Dispose of hydraulic fluid in accordance with local regulations.
3. Set pump in its level upright position.
4. Fill with good quality hydraulic oil to within 3/8" of the oil filler screw hole opening. Reinstall oil filler screw.
Lubrication
A periodic coating of light lubricating oil to pivot points and hinges will help to prevent rust and assure that pump
assembliesmovefreely.
Cleaning
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an
oily cloth.
Note: Neverusesandpaper or abrasive materialon these surfaces!
Storage
When not in use, store with the pump piston and ram fully retracted.
