MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. We recommend Mobil DTE 13M or equivalent.
Adding/ Changing Oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered remove cover plate, then oil ller plug.
2. Lay jack on its side and drain uid into a suitable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
3. Set jack in its upright, level position.
4. Fill with oil. Proper oil level is just below the rim of the opening. Reinstall the oil ller screw.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
wheels move freely and the pump functions smoothly. To help ensure trouble free operation, an inline air dryer and
oiler is recommended.
Cleaning
Periodically check the ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sandpaper or abrasive material on ram surfaces!
Storage
When not in use, store the jack with saddle fully lowered.

technical service
Jack will not lower after unloading • Reservoir overlled
• Linkages binding
• Drain uid to proper level
• Clean and lubricate moving parts
Poor lift performance • Fluid level low
• Air trapped in system
• Ensure proper uid level
• With ram fully retracted, remove oil
ller screw to let pressurized air
escape. Reinstall oil ller screw
Will not lift to full extension • Fluid level low • Ensure proper uid level
