Bolt-On Mounting Instructions
(Illustration shown is for a 3" or 4" high trailer frame. If trailer has a 5" frame, mount bracket
rotated 90 degrees)
1. Place the jack against the trailer tongue and position the mounting straps (A) on the opposite side of the tongue. Place the straps
so the flat side is against the tongue. Make sure the holes in the bracket and straps are in line.
2. Insert the four bolts (B) through the bracket and straps (two bolts on the top of the tongue and two below the tongue). Position
the jack so that the top bolts rest directly on the top of the tongue and the bottom bolts are as close to the tongue as possible.
The gap between the mounting bolts and the trailer tongue is not to exceed 1/16".
3. Secure with locknuts (C). Torque the nuts to 25 ft-lbs.
4. Check for clearance of handle swing, trailer light cables, and coupler clearance.
MOUNTING INSTRUCTIONS

Before mounting your trailer jack, check for interference from recessed ball mounts, trailer coupler, hitch or hitch plates and/or vehicle bumper. Rotate the
jack handle to check that the swing is not obstructed. If the jack is of the swing-away or swivel design, check the unit in both vertical and horizontal
positions. When the swing-away jack is in the horizontal or storage position, there should not be any interference from structural members of the trailer or trailer coupler. On all
jacks check that proper ground clearance has been achieved and will not contact the towing vehicle when in a tight turn. If the jack is not installed correctly, any interference (steep
inclines, angled turns etc.) may cause non-repairable damage to the jack and/or trailer. After installation is complete, check that jack operation has not been impaired in any way.
ASSEMBLY INSTRUCTIONS
OPERATING INSTRUCTIONS
MAINTENANCE
Handle Assembly:
Place one spacer over the
3/8" x 4.25" bolt. Lightly grease split tube spacer. Then
place the bolt and tube spacer assembly through the split
tube spacer. Then place the bolt and spacers through the roller.
Insert the bolt through the handle. Install the 3/8" locknut onto the
bolt and tighten. Adjust the nut so that the bolt no longer turns
freely. A minimum of two full bolt threads must be visibly
extended through the nut.
Rotate the jack handle clockwise to raise, or counter-clockwise to lower the
jack.
NOTE:
If the caster wheel does not have ground contact, it is necessary
to keep the caster from rotating when cranking the jack handle.
Swing-Away Swivel Jack Operation
This style jack is designed to be swiveled into a horizontal or storage position.
In both the vertical and horizontal positions, the plunger must be securely in
positioned in the mating hole in the mounting bracket. To place the jack into the
horizontal position allow about 2" of ground clearance beneath the footplate or
caster wheel. Pull the plunger pin out of the opening and swivel the jack. Rotate
either left or right until the plunger pin snaps into the proper mounting bracket
hole.
NOTE:
To avoid damaging the handle while trailering in the horizontal
position, secure the handle to the jack with a bungee cord or a rope.
To return jack to the vertical position, pull the plunger pin out of the hole and
rotate to the vertical or lifting position. At this point, the jack can be pulled or
pushed until the plunger pin snaps into the mating hole in the mounting bracket.
Drop Leg Operation for Added Height
1. Make sure the jack is in the up position and the trailer tongue weight is
supported by the tow vehicle. 2. While holding the foot plate with one hand,
pull the pin to release the drop leg. 3. Lower the foot plate to the desired height
(or to the ground) and replace the pin to secure the drop leg.
The internal gearing and bearings of the jack must
be kept lubricated. Using a needle nose applicator,
pump a small amount of automotive grease through
the lubrication opening. The lubrication opening can
be found on the side of the jack tube, right above
the support plate. Rotate the jack handle to
distribute the grease evenly. Lightly grease the inner
tube of the jack using the same type of grease. A
light weight oil must be applied to the handle unit at
both sides of the tube. The axle bolt and nut
assembly of the caster wheel must also be
lubricated with the same light weight oil.
