While running the bed up view the hydraulic fluid through the breather cap opening, you may see the fluid returning into the tank. If you see any air pockets or aera- tion of the fluid, please stop and allow the fluid to settle and continue to raise 1/3 of the way up.

  2. b) Once you reach 1/3 of the way up, press the down button to return the trailer bed or deck to it fully seated position (down).

*Please insure that the fluid level does not drop below the half full level of the reservoir while running the power unit.* 2) Press the up button on the hand held remote pendant, to run the trailer bed up 2/3 of the way up.
