MAINTENANCE
Important:
Use
ONLY
good grade hydraulic jack oil.
Avoid mixing different types of fluid and
Never
use
brake fluid, turbine oil, transmission fluid, motor oil or
glycerin. Improper fluid can cause failure of the jack and
the potential for sudden and immediate loss of load. We
recommend Mobil DTE 13M.
Adding oil
1. With saddle fully lowered set jack in its upright, level
position. Locate and remove oil filler plug/screw.
2.
Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler hole. Reinstall the oil filler
plug/screw.
Changing oil
For best performance, replace the complete fluid supply
at least once per year.
1. With saddle fully lowered, remove the oil filler plug/
screw.
2. Lay the jack on its side and drain the fluid into a
suitable container.
Note:
Dispose of hydraulic fluid in accordance with
local regulations.
3. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler hole. Reinstall the oil filler
plug/screw.
Lubrication
A periodic coating of light lubricating oil to pivot points,
axles and hinges will help to prevent rust and assure
that wheels, casters and pump assemblies move freely.
To help ensure trouble free operation, an inline air dryer
and oiler is recommended.
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 the jack with saddle fully
lowered.
REPLACEMENT PARTS
(refer to page 6 thru12)
Not all components of the jack are replacement

TROUBLESHOOTING
Symptom
Possible Causes
Corrective Action
Jack will not lift load
• Release valve not tightly closed
• Overload condition
• Air pressure inadequate
• Ensure release valve tightly closed
• Remedy overload condition
•
Ensure adequate air pressure
Jack will lift, but not maintain
pressure
•
Release valve not tightly closed
• Hydraulic unit malfunction
•
Ensure release valve tightly closed
• Discontinue use, contact Omega
technical service
Jack will not lower after unloading
• Reservoir overfilled
• Linkages binding
• Fluid level low
• Drain fluid to proper level
• Clean and lubricate moving parts
• Ensure proper fluid level
Poor lift performance
• Fluid level low
•
Air trapped in system
• Ensure proper fluid level
•
With ram fully retracted, remove oil
filler plug/screw to let pressurized
air escape. Reinstall oil filler plug/
screw
Will not lift to full extension
• Fluid level low
• Ensure proper fluid level
