Battery Cables
To minimize voltage drop, increase the gauge size of the battery cables
as the length of the positive and ground cables increase. Low voltage will
cause the motor to run higher amps causing damage to other electrical
components.

Bleed Cycle Instructions
- Remove the breather cap to view the hydraulic fluid while operating the hydraulic power unit
- Press the up button on the remote pendant and run hydraulic jack or hoist cylinder 1/3 of the
way up. You may see fluid returning into the reservoir. If you see air pockets or aeration of the
fluid, stop and allow the fluid to settle and continue to raise 1/3 way up.
- Once 1/3 of the way up, press the down button to return fully seated position of the hydraulic
jack or hoist cylinder.
- Make sure the fluid level does not drop below the half full level of the reservoir while running the
power unit
- Press the up button again on the remote pendant and run hydraulic jack or hoist cylinder 2/3 of
the way up. Once 2/3 of the way up is reached, press down button on the remote pendant to a
fully seated position again.
-
Again make sure the fluid level doesn’t drop below the half full level of the reservoir
- Press the up button again on the remote pendant and run hydraulic jack or hoist cylinder to full
stroke
- While running and if you see any air pockets or aeration of the fluid in the reservoir, stop and let
the fluid settle, then continue to raise the hydraulic jack or the hoist cylinder
- You may have to repeat this process more than once to completely purge all the air out of the
system
