THE CHAIN.
2. Disengage the Safety Locks on both Columns using
the Single Point Release Handle near the power unit
or by pulling the two Manual Release Cables located
on each carriage (depending on model of 2 Post Lift

3. Using a bungee cord or someone’s help depress and secure the Lowering Valve
handle. Go to each cylinder and conrm that the silver ram is completely retracted
into the black outer sleeve. If it is not, then pull the chain or push down on the
pulley in order to fully collapse the cylinder.
4. At this point any air should be gone from the lift hydraulic system, if not, repeat the
above steps 1 through 3.
After doing this procedure the lift arms should travel up and down
smoothly and at a consistent speed during operation.
