Lubrication; Corrective Action - Omega Lift Equipment 66150C Mode D'emploi

Bleeding/ Venting Trapped Air
1. Bleed air from ram: Place pump at a higher elevation than the hose and ram as shown in figure 4 below. The
objective is to float the air bubbles up hill and back to the reservoir where they belong. Close valve and extend
ram as far as possible. Open valve fully allowing oil and air to return to reservoir. Repeat this procedure two
or three times will do the trick.
2. Bleed air from pump: With ram fully retracted, remove oil filler screw to let pressurized air escape, then rein
stall oil filler screw.

Lubrication

A coating of light lubrication oil to pivot points, axles and hinges sections every 3 months, will help to prevent rust.
Rust prevention
Check cylinder every 3 months for any sign of rust or corrosion. Clean as needed and wipe with an oil saturated cloth.
Storage
When not in use, always leave the cylinder plunger fully retracted. Keep in dry, protected area, do not exposed to
corrosive vapor, dust or other harmful elements.
