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.

(see INTENDED USE) on a stable
support. Make sure the load is oriented in the upright position. 9
2) Apply the vacuum pads to the load as previously directed.
3) When the vacuum level registers above 16" Hg [-54 kPa] on the vacuum gauge, turn off or
disconnect the power source (as appropriate).
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,
