WARNING
-
The owner must inspect, or appoint a
knowledgeable person to inspect the jack for signs of
corrosion and / or excessive wear. Visual inspection
should be made before each use of jack, checking for
abnormal conditions. Regular inspections should be
made weekly for daily use and monthly for intermittent
use. Each jack must be inspected immediately if
subjected to an abnormal load or shock. Any jack
which appears to be damaged in any way, is found to
be badly worn, or operates abnormally shall be
removed from service until necessary repairs are
made. Contact the manufacturer using the contact
information printed on the back cover of this manual.
12.1
Structural inspection
Equipment must be removed from service and inspected
for damage immediately if subjected to an abnormal
shock or load. Failure to heed this warning may result in
personal injury and / or property damage.
It is critical that each lift unit be inspected regularly for
any signs of wear or damage that might affect its ability
to perform lifts safely. Any lift unit that appears to be
damaged in any way, is found to be badly worn, or
operates abnormally must be removed from service
until necessary repairs are made. Contact the
manufacturer (using the contact information on the
back cover of this manual) if you need to have a lift unit
serviced or if you have any questions about how to
address any wear or damage observed on a lift unit.
The employer, owner, and/or manager are responsible
for maintaining the lift units in good, serviceable
condition. Employees must be trained on how to
inspect lift units. Before each use

Regular inspections should include the following:
To prevent serious injury or death from a falling vehicle,
all inspection and maintenance procedures must be
performed
after
the jack has been removed from
service. Position the lifts so you have clear access to all
sides of the lift for inspection and service.
Inspect the lifts for any cracks, chips, or signs of
excessive wear. Visually inspect the welds.
Raise and lower the lift through its full range (up and
down)—it should move smoothly. If the lift stutters
when raising or lowering (i.e., it moves in a jerky
fashion) the slide pads may need to be re-lubricated.
Refer to the “Periodic lubrication” section on page 22.
Inspect the slide pad contact surfaces on the base
post for damage, such as gouging, warping, etc.
All controls should operate smoothly and freely.
Inspect the down stop pawl to make certain it rotates
forward and backward freely. If the pawl does not
move freely, it may need to be greased. Refer to the
“Periodic Lubrication” section of this manual.
If any irregularities or problems are detected during an
inspection, the stand must be removed from service
immediately and repaired. Contact the manufacturer
using the contact information on the back cover of
this manual.
