6.1 PURGING AIR FROM HYDRAULIC SYSTEM
During transportation air bubbles become trapped inside the jack
pump, reducing its efficiency. Bleed air out of the jack's hydraulic
system as follows:
Open release valve, then remove oil plug .
Operate pump handle rapidly for a minimum of 15 full strokes to force
air out.
Close release valve, replace oil plug.
Jack should now operate normally. If not, repeat purging procedure as
needed.
Should the jack fall over before use or be transported in any position
other than upright, it may be necessary to re-bleed the unit before use,
as advised above.
