Inspection – before each use
8.1
Visual inspection of the jack must be made before each
use of the jack. The jack should be immediately removed
from service if any of the following conditions are detected
or observed:
The lift pad or extended lift pad is cracked, chipped, or
shows signs of excessive wear.
The ram or extension screw shows signs of damage
such as bends, twists, cracks, chips, corrosion, misuse,
or excessive wear.
The jack's controls or wheels do not operate smoothly
or freely.
An oil leak is observed.
Any abnormal condition or sign of damage that
suggests the jack will not work properly.
Inspection – periodic
8.2
The jack owner (or a knowledgeable person appointed by
the owner) must give the jack a more thorough inspection
weekly (if it is used on a daily basis) or monthly (if used
less frequently). In addition to a visual inspection (as
described above), the inspector should also operate and
move the jack to assist in identifying any problems that
might exist. The jack must be removed from service and
repaired if the jack appears damaged, if it is badly worn, or
if it operates abnormally.
Inspect lift pad and extended lift pad and remove jack
from service if either lift pad is cracked, chipped, or
shows signs of excessive wear.
Raise and lower the ram to ensure it moves smoothly
through its full range. Inspect the ram and extension
screw for damage such as bends, twists, cracks, chips,
corrosion, misuse, or excessive wear.
Raise and lower the ram and extension screw to ensure
that all controls operate smoothly and freely.
Move the jack forward and backward on its wheels to
ensure that the wheels rotate smoothly and freely.
Inspect for oil leaks. If oil leaks occur, refer to the
"Troubleshooting" section of this manual.
