APPENDIX E

JACKS AND STANDS

E-1. Daily Inspection. The following items shall be inspected daily or before use:

a. Check for proper marking, i.e., rated load (sustaining and lifting, if appropriate).

b. Check for cleanliness and proper lubrication.

c. Check for broken, cracked or distorted mechanical parts or housings, loose bolts or rivets, and

other evidence of mishandling.

d. Check for hydraulic leaks; worn, bent, or damaged screw threads; cracked or broken rack

teeth; scored or damaged ram; improperly functioning swivel heads and caps; improper engagement

or extreme wear of pawl and rack, as appropriate to type of jack.

e. Check that handle is free from grease and oil.

f. Other items as specified in technical manuals or manufacturer's instructions, which may affect

operation.

E-2. Periodic Inspection. Complete inspection of jacks and stands shall be performed every 6

months. Periodic inspections shall include the items of E-1 above, requirements of any applicable

technical manual, manufacturers recommendations, and the following:

a. Check for corrosion of metal parts.

b. Jack should be disassembled for cleaning and examination for internal wear or damage if

external appearance indicates there may be internal difficulty.

E-3. Tests. When required by paragraph 4a, perform a functional test to determine operability of

the equipment. Functional testing shall consist of lifting a characteristic load (determined locally),

holding it at an appropriate height for one minute, maneuvering it in a manner which will simulate the

operation of the lifting device in the working environment, and lowering it to its original position. For

lifting devices used to handle hazardous materials, conduct the function test as above, using an inert

item equal in weight to or heavier than (not to exceed the manufacturers load rating of the device) the

heaviest item normally lifted by the devices as its characteristic load. A visual inspection will be

performed prior to and after functional test is performed. Record pretest and post-test findings,

actions taken, and test date in the end item's historical records.
