MAINTENANCE
A. Service Jack:
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 screw.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler hole. Reinstall the oil filler screw.
Changing oil
For best performance, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove oil filler 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 oil filler 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.
Cleaning
Periodically check 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.
B. Jack Stands:
Periodically inspect each stand. Ensure all parts move freely. Do not apply oil or grease to any portion of this
product. If rust appears, sand affected area and cover with suitable utility paint. Please note that there is no
replacement part applicable to this device.
Storage
Store stands in upright position and in a clean, dry area.

TROUBLESHOOTING
Symptom
Possible Causes
Corrective Action
Jack will not lift load
• Release valve not tightly closed
• Load is too heavy
• Ensure release valve tightly closed
• Consider higher capacity jack
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 screw to let pressurized air
escape. Reinstall oil filler screw
Will not lift to full extension
• Fluid level low
• Ensure proper fluid level
