o
Failre to read and understand this manual before using or servicing a trailer
stabilizing jack is misuse. Any person who will use or maintain this product must be familiar with all instructions and warning in this manual.
o
DO NOT perform maintenance on or repair a loaded (in use) jack.
o
DO NOT use this product unless all labels (see "Label placement diagram on p.
8) are in place and legible.
o
DO NOT use a stabilizing jack if it is damaged.
o
ONLY use the stabilizing jack on compacted, improved surfaces (i.e. concrete) that are even and level. This product will not stabilize trailers parked on
uneven or sloped ground.
o
DO NOT use a stabilizing jack to support trailers. This jack designed to stabilize trailers that are supported by landing gear (trailer dolly jack).
NEVER use a stabilizing jack without deployed landing gear in normal condition.
o
ONLY qualified maintenance personnel should maintain and repair this product. Improperly maintained stabilizing jacks might become unsafe to use.
o
DO NOT modify a trailer stabilizing jack in any way without first obtaining
written authorization from VESTIL. Unauthorized modifications automatically void the Limited Warranty (see p. 10) and might make the product unsafe to use.
o
H-LO-J-BEAM only: when necessary, replace oil with a mineral-based hydraulic oil of viscosity grade of 75 SUS at 100°F (ISO 15 cSt @ 40°C).

TRAILER STABILIZING JACKS, MANUAL Rev. 0917
USE INSTRUCTIONS TRAILER STABILIZING JACK (ALL MODELS)
Review OSHA standard 29 CFR 1910.178 “Powered Industrial Trucks” before using trailer stabilizing jacks. The
following provisions are relevent to the use of stabilizing jacks
* 29 CFR 1910.178(k)(1) -- “The brakes of highway trucks shall be set and wheel chocks placed under the rear wheels
to prevent the trucks from rolling while they are boarded with powered industrial trucks.
* 29 CFR 1910.178(k)(3) -- “Fixed jacks may be necessary to support a semitrailer and prevent upending during the
loading or unloading when the trailer is not coupled to a tractor”
* 29 CFR 1910.178(m)(7) -- “Brakes shall be set and wheel blocks shall be in place to prevent movement of trucks,
trailers, or railroad cars while loading or unloading. Fixed jacks may be necessary to support a semitrailer during loading or unloading when the trailer is not coupled to a tractor. The flooring of trucks, trailers, and railroad cars shall be checked for breaks and weakness before they are driven onto."
Use and Operation:
The standard model trailer stabilizing jack is intended to be used to support the ends of a semitrailer that is parked against a loading dock and not connected to a truck’s fifth-wheel. The semitrailer must be situated on a flat, stable, improved (preferably concrete) surface.
The load rating in pounds is shown on the information label located on the side of the jack (see Label placement diagram on p. 8). Two ratings appear on the label: 1) a static rating = how much weight the jack will stabilize; and 2) a lifting rating = how much weight the screw mechanism of the jack can lift.
NOTE: The need to use trailer stabilizing jacks, the number necessary, and the exact placement of jacks under the
semitrailer must be determined by a qualified persons responsible for the loading or unloading of the trailer.
The following is a list (not all-inclusive) of circumstances under which use of a trailer jack is recommended:
To reduce the risk of the semitrailer’s landing gear failure.
To reduce the risk that the front of the semitrailer might tend to tip up when a fork truck enters the rear of
the semitrailer, such as with trailers having axles that are further away from the dock than is typical.
The heavier the fork truck and load, the more likely it is that a trailer stabilizing jack(s) will be needed.
Shorter semitrailers are more likely to need two jacks -- one under each corner of the nose end.
WARNING
operator and bystanders. Before installing stabilizing jacks beneath a semitrailer:
1) It must be entirely and stably supported by its landing gear.
2) The trailer wheels must be properly immobilized to resist creep or roll.
3) The surface on which the jack(s) will be used must be even, level, compacted and improved (concrete) to prevent the jack from sinking into the ground.
4) Confirm that the underside of the trailer is sound where the stabilizing jack(s) will contact it. If the point of contact is unsound, the jack might break through the trailer.
5) DO NOT exceed the load ratings!
mechanism (the same handle used for moving the jack around is used for the ratchet), models SP-TOP, SJ-35, and SJ-35-EF utilize handles that are affixed to the screw hub, model CJ-BEAM uses a dual-shaft (for two speeds) hand
crank mechanism, and model H-LO-J-BEAM utilizes a hydraulic jack.
Tip the stabilizing jack onto its wheels and roll it under the hitch-end (front) of the semitrailer. If using a single jack, place it on the centerline of the trailer’s width. When using two jacks, place one under each front corner.

To raise and lower the top cap: models BFSJ-2748, LO-J-BEAM, LO-J, HI-J, and SP-TOP-R all utilize a ratcheting
NOTE: Additional stabilizing jacks might be required under the rear corners of the semitrailer if the distance from the rear axle to the back end of the semitrailer is more than ¼ of the overall length of the trailer.
Adjust the height of the jack so that the top cap of the jack presses firmly against the underside of the semitrailer frame. However, the trailer landing gear must at all times remain in solid contact with the ground in order to provide
support for the front end of the trailer
Jacks must be removed before backing a tractor underneath the semitrailer. To remove a trailer jack, lower the top cap so that it no longer contacts the bottom of the trailer; then tip the jack backwards and roll it out from under the trailer.

INSPECTIONS & MAINTENANCE (ALL MODELS)
Only qualified individuals trained to inspect and maintain stabilizing jacks should perform inspections and
maintenance.
Inspect the jack as described in parts A and B below.
WARNING: If damage is evident, or if any problems are discovered during an inspection, immediately tag the
jack "Out of service" and remove it from service UNTIL it is restored to normal operating condition.
(A) Each day inspect the jack for the following conditions:
1.) Visible damage to the screw, base, or screw hub.
2.) Free movement of the top cap.
3.) Oil leaks (H-LO-J-BEAM only).
(B) At least once per month, inspect the following components. DO NOT use the jack until it is restored to normal operating condition.:
1.) Screw threads
a. Determine if threads are adequately greased: apply a standard bearing grease to the screw threads. Fully extend the screw & apply grease liberally to the threads; then wind the screw into the jack to coat
the threads. In colder climates, synthetic grease will reduce the amount of effort required to install the jack but is optional. Remove grease from the frame and handles before returning the jack to service.
b. Inspect threads for severe wear or damage: if the screw wobbles inside the screw hub, the screw assembly is significantly worn and should be replaced before returning the jack to service.
3.) Screw adjustment mechanism - the mechanism should operate smoothly.
4.) Jack frame: examine the jack for cracked welds or metal fatigue.
5.) Wheels, axles, or wheel bearings: inspect for looseness, excessive wear, or damage.
6.) Handle grips: damaged, loose, or missing Install adhesive to the inside of the grips and reinstall them if they
become loose.
7.) Hydraulic oil (H-LO-J-BEAM only): the oil level should be just below the fill hole of the reservoir with the jack in the lowered position. Replace the oil with hydraulic oil of viscosity grade 70 to 85 SUS at 100°F, (ISO 15 at 40°C).
8.) Labels (see "Label placement diagram" on p. 8): the jack should be labeled at all times as shown in the
diagram. Replace any label that is damaged or not easily readable.
The following requirements are from OSHA standard 1910.244 titled, “Hand and Portable Powered Tools and Other Hand-Held Equipment”:
1910.244(a) -- Jacks -
1910.244(a)(1) -- Loading and marking.
