OPERATION
Operate the hydraulic pump to advance and retract the cylinder. Do not continue pumping when cylinder is fully
extended or retracted. Internal pressure will build up and may damage the seal of the cylinder.
WARNING: To help prevent material fatigue if the cylinder is to be used in a continuous application, the load
!
should not exceed 85% of the rated capacity.
! WARNING:Your cylinder, hose(s), couplings and pump all must be rated for the same maximum operating
pressure, correctly connected and compatible with the hydraulic fluid used. An improperly matched system
can cause the system to fail.
!
WARNING: All personnel must be clear before lowering load.
MAINTENANCE
1. Inspect hoses & connections daily. Replace damaged components immediately with Omega replacement parts only.
2. Tighten connections as needed. Use pipe thread sealing compound when servicing connections.
3. Always use clean, approved hydraulic fluid and change as recommended or sooner if the fluid becomes
contaminated (never exceed 400 hours). Follow pump manufacturers instructions for changing and adding
hydraulic fluid. Use only good quality hydraulic fluid. We recommend using a premium hydraulic fluid when using
with hand pump or air pump; BVA Hydraulics Oil (F01) or equivalent when using with electric pump. NEVER use
brake fluid, transmission fluid, turbine oil, motor oil, alcohol, glycerin etc. Use of other than good quality hydraulic
oil will void warranty and damage the cylinder, pump, hose etc.
4. Use an approved, high-grade pipe thread sealant 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 and obstruct the flow of fluid and adversely affect function.
Lubrication & Cleaning
Keep cylinder clean at all times.
1. Any exposed threads (male or female) must be cleaned and lubricated regularly, and protected from damage.
Lubricate with light machine oil.
2. If a cylinder or ram has been exposed to rain, snow, sand, airborne abrasive, or any corrosive environment, it
must be cleaned, lubricated, and protected immediately after exposure. Daily clean exposed ram with clean cloth
dampened with light machine oil. Protect exposed ram from the elements at all times.
3. Keep the hydraulic system as free of dirt as possible. When not in use, couplers must be sealed with dust covers.
All hose connections must be free of dirt and grime. Any equipment attached to the cylinder must be kept clean.
Storage
Cylinders should be stored with ram plunger fully retracted in a dry, protected area, not exposed to corrosive vapor,
dust or other harmful elements. When a cylinder has not been used for a period of 4 months, it should be connected
to a pump and fully extended and then retracted a minimum of 5 times. This cycle will lubricate the cylinder wall,
reducing the possibility of corrosion and damage thereof.
How to remove faulty coupler:
If cylinder does not retract,
1. Secure load by other means.
2. Depressurize cylinder, pump, and hose, then remove cylinder from application.
3. Disconnect and replace with new coupler.
Important: Do not attempt to grasp with pliers or wrench without first 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 cylinder as
shown in figure 2.
2. Operate pump to fully extend and retract the cylinder two or three
times. The objective is to force the air bubbles up hill and back to
the pump reservoir.
3. Follow pump instructions to bleed the air from pump reservoir. On
most pumps, air can escape by opening the oil filler cap.
