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 premium jack oil.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.
2.
Fill with oil until just below the rim of oil filler hole. Reinstall the oil filler plug.
Changing oil
For best performance, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove oil filler plug.
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 just below the rim of oil filler hole. Reinstall the oil filler plug.
Lubrication
1. A periodic coating of light lubricating oil to pivot points will help to prevent rust and assure that pump assemblies
move freely.
2. Air pump should be internally lubricated before each use. Use good quality air tool lubricant. If no inline oiler
is used, pour a teaspoon of air tool oil into the air control valve inlet. Operate the jack with air pressure to fully
distribute the oil inside the air motor.
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.
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
•
Refer to Bleeding/ Venting
Trapped Air instructions
Will not lift to full extension
• Fluid level low
• Ensure proper fluid level
