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 = lbs force, P = pressure in PSI, and A = effective ram area in in².
Ram Area of 50364 is: 0.998 in²
Ram Area 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.
! DANGER !
• If oil leakage is detected, discontinue use of the
ram immediately and contact your nearest Sears.
The ram could develop excessive pressure and
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.

WARNING
SAFETY INSTRUCTIONS (cont.)
To avoid crushing and
related injuries:
NEVER work on, under
or around a load
supported only by ram.
ALWAYS use
adequately mechanical
support such as rated
jack stands.
!
• All WARNING statements must be carefully observed
to help prevent personal injury.
• 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
this equipment.
• Do not use as a vehicle lifting device or as a
vehicle support.
• 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
offset atachments.
• Monitor pressure and load at all times.
• Always verify load with calibrated load cell and
indicator, known good pressure gauge or equivalent
devices.
• Do not modify this device.
• Failure to heed these markings may result in
personal injury and/or property damage.
Hydraulic Hoses and Fluid 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. Before
operating the pump, all hose connections must be
tightened with the proper tools. Do not overtighten.
Connections should only be tightened securely
and leak-free. Overtightening can cause premature
thread failure or high pressure fittings to burst.
