AIR BLEEDING PROCEDURE FOR BLAZER 9000 

Step #1 Fill the power unit reservoir with Dexron III Mercon Automatic Transmission Fluid or equivalent, 
approximately 7.5 quarts to start with, check all connections for proper security and clearances around and 
under both of the lifting surfaces, example,…. binding, chafing, and pinching.

.

Step #2  Prior to connecting the hydraulic hoses to the cylinders, press and hold the green “lifting” button on 
the power unit, this will flow fluid through the hydraulic lines/hoses, flushing any foreign material along with 
any air from the system and allow you to inspect for possible leaks. Cycle the pump until clear fluid is coming 
out of both lift pad hydraulic hoses + approximately 1 quart

Step #3  You will need to manually raise each lifting pad to the 

KLJKHVW

 safety lock setting, making sure that it 

is securely latched into the latch bar on the base plate.

Step #4  Press and hold the green “lifting” button until both pads are elevated enough to clear the first set of 
locks, then release.

.  Depress and hold the air lock release button, this should 

raise the locks out of the latch bar on both left & right side base plates, simultaneously depressing the red 
lowering button, the pads should begin to lower within a few moments. Allow the pads to lower all the way to 
bottom. Duplicate this process numerous times, 5 to 6 cycles, increasing the lifting height by one extra lock 
per cycle.  Each completed operation should facilitate a more even pad elevation and smoother equipment 
function. Some installations may require more or less cycles to accomplish this stage of the bleeding process.

Step #5.   Once you have both lifting services raising/lowering evenly and smoothly you now are ready to put a 
load on the system to complete the bleeding process. As in Step #1 an inspection around and under each lifting 
surface for possible leaks and clearances is required. A mid-size vehicle of approximately 4500 + lbs will be 
needed to finish this process.

. Stage the vehicle for lifting, utilizing necessary adapters as required, announce the lift operation, 

and then when all is clear depress the green “lifting” button. Raise the vehicle until the tires are clear of the 
floor surface, at this point you will release the green button and depress the lock release button,

. Now you can depress the red “down” button allowing 

the vehicle to lower down. Make sure that for each cycle you allow the pads to bottom out before starting up 
again. Continue this process for a few cycles until the vehicle is coming up and going down level/smooth.  

         Note: Do not adjust any valves on the power unit pump without prior contact and instructions to do so
