whether or not they constitute a hazard.
If such a determination is made, the jack
shall be removed from service until the
deficiency is corrected.
(1) Check for scored or damaged control
rod.
(2) Check for scored or damaged standard
and keys.
(3) Check for any abnormal conditions,
loose cotter pins, cap screws, and nuts.
(4) Inspect all visible components for
condition and security of all parts.
(5) Check for adequate lubrication. (Refer
to paragraph 2-9).
(6) Check for foreign substance which may
damage or interfere with proper
operation of the jack.
NOTE
A jack that has been idle for one year or
more shall be inspected in accordance with
Frequent Inspection (Table 2-1).
2-5. Periodic Inspection
Visual inspections by designated
qualified personnel, making records of apparent
external conditions, provide the basis for a
continuing evaluation.
a.
Normal service—one year
b. Severe service—before each use or
daily, whichever is less frequent, unless external
conditions indicate that disassembly should be
done to permit detailed inspection.
c.
Perform inspection in the same manner
as Frequent Inspections, except that records are
kept. A dated and signed inspection record shall
be kept on all Periodic Inspections. See Figure
2-1 for a typical “Inspector’s Record.”
NOTE
It is recommended that the Periodic
Inspection be performed by and Authorized
Warranty Service Center or appropriate trained
authorized individuals.
a.
During Periodic Inspection, if external
appearance indicates possible internal difficulty,
the jack shall be disassembled for cleaning and
examination for internal wear or damage.
See Table 2-1 for Minimum Inspection
Schedule.
2-6. Special Inspection Requirements
a. Air motor blades:
Motor blades should be inspected for
wear after each 100 jack lifting cycles. When
blades are worn to a thickness of 25/32 inch or
less, they should be replaced.
b.
Lifting Nut:
The jack’s lifting nut should be
inspected for wear after every 100 jack lifting
cycles. In applications where the jack is
exposed to dirt, dust, metal chips, or other
contaminants, the inspection frequency should
be increased.
WARNING
Failure to properly inspect and maintain the
lifting nut could result in a dropped load and
serious worker injury.
To inspect the lifting nut refer to Figures
4-1 through 4-8 and Figure 2-2, and proceed as
follows:
(1)
Fully extend the upright unloaded jack.
(2) Loosen the two screws and remove the
gage from the jack.
(3)
Clean grease from the hole which had
been covered by the gage.
(4)
Insert the slender end of the gage into
the hole.
(5)
If the thin tip of the gage can be made to
enter the space between the top flank of the
lifting nut thread and the bottom flank of the
lifting screw thread, the lifting nut is worn out.
(Refer to Figure 2-2).
(6)
Remove jack with worn out lifting nut
from service and ensure that it is properly
repaired before returning to service.
