
Prevent trailer wheels from moving using wheel chocks while raising or lowering.

Keep body parts clear from under jack and tongue when applying and releasing load, or moving
trailer.

Release the Power Switch when the motor slows, or switches off, to prevent damage to the motor.
Wait 15 seconds for the motor to reset before operating the jack again.

Do not stack blocks under the jack’s foot to increase the height. Stacked blocks may become
unstable and fall.

When using the drop foot or drop leg, make certain the supplied pin is fully inserted through both
sides of the inner tube and the drop tube before using the jack.

If the trailer jack has a drop leg, never attempt to adjust the drop leg when there is any load on the
jack.

Park your trailer on a level surface and block all trailer wheels.

For nighttime hook-ups, flip the light switch ON to illuminate the work area.

Before operating the jack, attach the foot with the 3/8” safety lock pin provided.

Extend the jack by pushing the operating switch UP. The drop leg may also be used to quickly
extend the jack. Make sure to reattach the lock pin after adjusting the drop leg to the desired
level. Under heavy use, the internal circuit breaker may open, causing the motor to switch off. In
this case, release the operating switch and wait 15 seconds for the breaker to reset before
resuming operation.

Retract the jack by pushing the operating switch DOWN. The jack will stop automatically at the
end of the extension or retraction stroke. If you attempt to extend or retract the jack and it does
not respond, it may be at the end of the stroke. If the jack fails to respond, try operating it in the
opposite direction. If it will not operate in either direction then see the troubleshooting section.
After full retraction, you may need to raise the drop leg also. Make sure to reattach the lynch pin
after adjusting the drop leg to the desired level.

I f for any reason electric power is lost or you need to disconnect the jack from the power source,
remove the rubber lid on top of the plastic cover. Insert the manual crank handle into the access
hole on the top of the jack, engaging the drive screw. While holding the crank firmly in place,
rotate it counter-clockwise to extend the jack, and clockwise to retract it.

Over or under extending the jack by holding the switch too long WILL NOT cause damage on the
gears of the jack.

Automatic thermal protection equipped on the trailer jack can prevent damage from the motor
overheating.
After Each Use
⚠
WARNING
•
After use, wipe external surfaces of the jack with a clean cloth.
•
Keep all moving parts lightly lubricated to prevent corrosion.
