Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures
before beginning work.

Only qualified individuals trained to understand mechanical devices should attempt troubleshooting and repair of
this equipment
To ensure the proper operation of trailer jacks, regular safety inspections and maintenance must be performed.
Inspections should be conducted at regular intervals based on the frequency and severity of usage, and the jacks should
be serviced at least every two months.
Note: If damage is evident, or if any problems are observed based on the inspection items below, remove the
stabilizing jack from service immediately.
(A) Inspect daily for:
1.) Visible damage to the screw, base, or screw hub.
2.) Free movement of the jack’s top cap.
3.) Oil leaks (H-LO-J-BEAM only).
(B) Inspect monthly for:
1.) Adequate grease on the lifting screw threads.
A standard bearing grease should be used on the screw. (To grease the jack screw, adjust it out to its full
extended length and apply grease liberally to the threads. Once greased, run the screw back down into the
jack to coat the entire thread. In colder climates, synthetic grease will reduce the amount of effort required
to install the jack but is not required. Remove any excess grease that may be on the frame or handles.)
2.) Worn or damaged lifting screw threads. Wear of the screw assembly is characterized by movement (wobble) of
the screw in the screw hub.
3.) Smooth movement of the screw adjustment mechanism.
4.) Evidence of weld cracks or metal fatigue anywhere on the jack.
5.) Looseness, excessive wear, or damage to the wheels, axles, or wheel bearings (where applicable).
6.) Damaged, loose, or missing handle grip(s). Install adhesive to the inside of the grips and reinstall them if they
become loose.
7.) Proper oil level (H-LO-J-BEAM only). The oil level should be just below the reservoir’s fill hole with the jack in
the lowered position. Use a hydraulic oil having a viscosity grade of 70 to 85 SUS at 100°F, (ISO 15 at 40°C).
8.) All the information/safety/warning labels being in place and in good condition. Contact the manufacturer for
replacements if necessary.

1910.244(a)(1) -- Loading and marking.
1910.244(a)(1)(i) -- The operator shall make sure that the jack used has a rating sufficient to lift and sustain the
load.
1910.244(a)(1)(ii) -- The rated load shall be legibly and permanently marked in a prominent location on the jack by
casting, stamping, or other suitable means.
1910.244(a)(2) -- Operation and maintenance.
1910.244(a)(2)(i) -- In the absence of a firm foundation, the base of the jack shall be blocked. If there is a possibility
of slippage of the cap, a block shall be placed in between the cap and the load.
1910.244(a)(2)(ii) -- The operator shall watch the stop indicator, which shall be kept clean, in order to determine the
limit of travel. The indicated limit shall not be overrun.
1910.244(a)(2)(iii) -- After the load has been raised, it shall be cribbed, blocked, or otherwise secured at once.
1910.244(a)(2)(iv) -- Hydraulic jacks exposed to freezing temperatures shall be supplied with an adequate antifreeze
liquid.
1910.244(a)(2)(v) -- All jacks shall be properly lubricated at regular intervals.
1910.244(a)(2)(vi) -- Each jack shall be thoroughly inspected at times which depend upon the service conditions.
Inspections shall be not less frequent than the following:
1910.244(a)(2)(vi)(a) -- For constant or intermittent use at one locality, once every 6 months,
1910.244(a)(2)(vi)(b) -- For jacks sent out of shop for special work, when sent out and when returned,
1910.244(a)(2)(vi)(c) -- For a jack subjected to abnormal load or shock, immediately before and immediately
thereafter.
1910.244(a)(2)(vii) -- Repair or replacement parts shall be examined for possible defects.
1910.244(a)(2)(viii) -- Jacks which are out of order shall be tagged accordingly, and shall not be used until repairs are
made.
