CHEDULE
Perform these tests when placing the lifter in service
initially
and
each time following a repair or
modification
. Correct any deficiency and retest before using the lifter.
Operational Tests
• Perform the V
ACUUM
T
EST
to follow.
• Test all features and functions of the lifter (see OPERATING FEATURES, OPERATION and
MAINTENANCE).
Load Test
Prove that the lifter can lift 100% of its Maximum Load Capacity (see SPECIFICATIONS), using an
actual load or an equivalent simulation.
9
Employ the following method to test with an actual
load:
1) Place a test load with appropriate L
OAD
C
HARACTERISTICS
(see INTENDED USE) on a stable
support. Make sure the load is oriented in the upright position.
10
2) Apply the vacuum pads to the load as previously directed.
3) After the vacuum pump stops running, disconnect the electrical connector uniting the battery
with the vacuum generating system.
Note: After the test is completed, move the valve handle to the “RELEASE” position (power
off
) before reconnecting the battery.
4) Raise the load a minimal distance, to assure that it is supported by the lifter.
5) Hold the load for 5 minutes. The load must not slip or fall during this time period. If it does,
conduct a V
ACUUM

and inspect each vacuum pad as indicated under V

: Inspection (see sections to follow). Correct any deficiency that is found and
retest the lifter.
Note: See MAINTENANCE topics to follow for additional directions about inspecting and testing
specific lifter components.

CHEDULE
Unless specified elsewhere in this
INSTRUCTIONS
manual, the lifter does not require
maintenance on a routine basis. Instead, maintenance must be performed whenever a
deficiency is indicated by routine inspections or tests. Any maintenance warranted must be
performed before resuming normal operation of the lifter.

ASME Standard B30.20 requires the lifter to be tested to 125% of its Load Capacity.
10
Flat Lifters are exempt from this requirement.
