Operation
Fill with fluid to the top of the reservoir. Replace the plug.
Note: Filling the reservoir when the trailer is in the raised
position will overfill the system and will cause an overflow
when the trailer is lowered.
To adjust the bypass, loosen the jam nut, rotate the set
screw, then tighten the jam nut. Generally, the proper set -
ting is for the set screw to be flush with the jam nut. If the
trailer will not raise, rotate the set screw “in” one full turn.
If the hydraulic handle will not stroke, rotate the set screw
“out” one full turn.
If air is in the system, it is necessary to “bleed” the air for
the hydraulic system to work properly. Loosen the hose
fitting slightly at the cylinder and allow the air to escape.
When pure hydraulic fluid flows from the fitting, retighten
the fitting. If necessary, stroke the pump to force fluid
through the system.

Filling the Tank
Connect the 2” quick couple fitting at the rear of the trailer
to the fill hose from the source. Open the 2” valve and start
the flow. When the tank is full, close the 2” valve.
Note: Ball valves are open when the valve handle is parallel
to the flow and closed when the valve handle is perpen -
dicular to the flow.
