73) Lower  the  lift  to  the  floor  and  raise  the  lift 

approximately one foot. 

74) Start  with  Idler  side  first.  Slowly  and  carefully 

loosen the bleed plug on top of the cylinder just 
enough  to  allow  the  entrapped  air  to  escape. 
Repeat for power side. 

75) Raise lift 6 inches. Repeat the previous step until 

no air comes out of cylinder. 

76) Pressure  test  hydraulic  system.  Energize  power 

unit, raise lift to full rise and continue to run motor 
for additional 10 seconds. (NOTE: pressure relief 
will make a high pitch squeal sound for these 10 
seconds.) Check hydraulic system for leaks.  

77) Energize power unit again for 10 seconds. With a 

clean  rag,  wipe  down  both  cylinder  rods.  (The 
cylinders are shipped with a small amount of clear 
anti-corosive  lubricant  that  will  be  forced  out 
through the wiper when the lift reaches full rise.) 

If  lubricant  is  not  wiped  clean  from  the 
cylinder  rod,  the  cylinder  will  apear  to  be 
leaking

78) Raise  lift  and  ensure  carriages  lower  into  same 

lock position. 

79) Adjust  synchronizing  cables  so  the  tension  is 

equal  in  both  cables  and  carriages  are  firmly 
sitting on locks. 

80) Cycle  lift  to  ensure  that  locks  operate 

simultaneously.  Adjust if necessary.

81) Demonstrate the operation of the lift to the 

owner/operator/employer using a typical vehicle 
and review correct and safe lifting procedures 
using the 

Lifting It Right

 booklet as a guide. 

82) Return all provided literature (including this 

manual) to the literature pack envelope and 
deliver the envelope to the 
owner/operator/employer. 

83) Complete the online warranty registration (refer 

to the included warranty statement).
