With the jack installed in the vertical position, remove the flush mounted fill plug from the top of the
reservoir and discard. Replace with breather cap. Failure to do so will cause the jack to
operate erratically.
To raise and lower the jack, simply push and hold the rocker switch in the up or down position. The
jack will hold a position by releasing the switch at any time. There is no need to take the weight off
the jack when storing the trailer, as the positive check valves in the system will not allow the jack to
bleed down.
*Note: When the jack is fully retracted, the fluid level in the reservoir should be approximately one
inch below the fill cap. If fluid needs to be added, use Dexron III automatic transmission fluid (the
same as used for a GM automobile).
The keyed switch must be in the off position and the key must be removed when the jack is not in
use and/or when the trailer is in transit. If unit is not supplied with a keyed switch, the +12v
battery lead must be fed through a power disconnect switch to fully isolate the system during
inactivity or travel. The minimum switch rating must be 100 ampere DC.
With any hydraulic application, holding any position on a cylinder must be done with safety in
mind. Failure in the system may cause the jack to retract or extend on its own. When working
under or near the trailer, always use jack stand of appropriate rating to support the weight of the
trailer.
Manual Override – Hand Pump - Pump # 2142 & 3126, 3170
The following procedure gives step-by-step instructions on how to operate the manual override to
either extend or retract the jacks.
Your AM series Single Leg Jack is available with a Manual Override, depending on the specific
unit ordered. If your unit is equipped with the Override Hand Pump, it is operated as follows:
To Extend your Jack:
1. Install a handle in the hand pump. Pump the handle to extend the jack. You may have to
pump 10-20 times before you build enough pressure and the jack begins to extend.
To Retract your Jack:
1. Locate the red knurled knob on the directional valve. Pull it out and turn ¼ turn. The knob
will remain in the "out" position. Do not use anything other than your fingers to manually
shift the directional valve.
2. Install a handle in the hand pump. Pump the handle to retract the jack. You may have to
pump 10-20 times before you build enough pressure and the jack begins to retract. Return
the directional valve to the normal position.
Caution: Following manual override operation, failure to return all valves to normal position
may result in one or more jacks drifting down from their retracted (stowed) position. For
directional valves, rotate the red knob until it "snaps" back to the normal position.
