Maintenance
If you discover any damage, have all damaged parts repaired or replaced before using
your Trailer Jack.
1. Regularly inspect the Springs (17) and Swivel Handle (15) locking pins to be sure they
will properly engage and lock the Jack in both the up and down positions. Check all of
the Hardware Sets (19) regularly to ensure that they are tight and the Jack is firmly
attached to the trailer tongue.
2. Keep the Swivel Plate (6) lubricated with light grease. Inspect it regularly for damage.
3. Keep the crank mechanism (inside the Outer Tube (7)) and the top shaft of the Inner
Tube (8) lightly greased. Ensure that this mechanism functions smoothly.
4. Inspect the Tire (18) regularly for damage. Keep the tire filled to a cold pressure of 30
PSI. Keep the axle lightly lubricated.
5. Inspect the entire unit for corrosion which may be caused by exposure to salt water or
weather. Rinse thoroughly and re-lubricate promptly after being immersed in salt water.
6. Keep all moving parts lightly lubricated to prevent corrosion. If corrosion develops, you
may paint exterior parts of the Jack to help arrest and prevent further damage.
Using the Jack to Mount The Trailer to the Towing Vehicle.
WARNING: Do not attempt to lift the trailer tongue if it is too heavy for you. You may
need assistance for some parts of this operation. This procedure requires at
least 2 people to be present.
1. If the trailer tongue is resting on the ground, pull the Swivel Handle (15) allowing the
Trailer Jack to rotate downward.
Keep your fingers clear.
2. If you are able, lift the trailer tongue, while the Jack rotates into the lowered position. If
the Tongue is too heavy get assistance.
3. Pull the Swivel Handle (15) out, then reengage the pins, locking the Jack into the
lowered position.
4. Rotate the Handle (1) clockwise to raise the trailer to just above the level of the towing
vehicle’s hitch.
5. Have an assistant spot for you as you move the vehicle close to the trailer. Or, if on
smooth ground, roll the trailer to the vehicle.
6. Mount the trailer onto the towing vehicle’s hitch.
7. Turn the Handle (1) counterclockwise to raise the Jack slightly off the ground, transferring
the trailer weight onto the towing vehicle.
8. Pull out the Swivel Handle (15), and rotate the Jack into its upright position. Be sure
that the Swivel Handle locking pins are fully engaged and the wheel chocks are removed
before driving away.
