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 in

.
Ram Area of Model 50040 is: 0.998 in

Ram Area of Model 50100 is: 2.411 in

You can refer to Load-Pressure correlation chart on
page 9.
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.
Wear protective clothing and safety
goggles to reduce the risk of injection.
To avoid crushing and related
injuries:
NEVER work on, under or around
a lifted load before it is properly
supported by appropriate
mechanical means such as jack
stands. Never rely on hydraulic
pressure alone to support load.
! WARNING
! DANGER
• If oil leakage is detected, discontinue use of
the ram immediately and contact your nearest
Omega authorized Service Center. The ram
could develop excessive pressure and cause the
ram, hose or coupler to burst, which could cause
serious injury or death.
! WARNING
• 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 ller screw unless ram is fully
retracted.
• Do not wear sandals and jewelry when
operating this equipment.
• Do not use as a vehicle lifting device or vehicle
support.
• 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 attacment connected.
• 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.
OPERATION
Note: Inspect before each use for evidence of uid
leaks, damaged hydraulic fittings, bent or broken
attachments and missing parts.
1. Locate and close release valve by turning it clockwise
until rmly closed. (Do not over tighten)
2. Operate by pumping handle. This will send uid
from the pump reservoir into the high pressure hose
assembly and into the ram assembly.
3. Continue pumping until ram reaches desired
position.
Note: Pump may be used in horizontal and vertical
position as illustrated (See gure. 2).
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 of a full turn. The
ram return system is spring loaded and the release
valve system is metered, allowing controlled retraction
of the ram.
