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. 9): the jack should be labeled at all times as shown in the
diagram. Replace any label that is damaged or not easily readable.
