• Inspect all parts of the electrical system for damage, wear or contamination that could
constitute a hazard, in compliance with all local codes and regulatory standards that are
relevant for the geographical region.
CAUTION: Be sure to use appropriate cleaning methods for each type of electrical
component, as specified by codes and standards. Improper cleaning
can damage components.
• Keep a written record of all Periodic Inspections.
If any deficiency is detected during the inspection, correct it before using the lifter. If
necessary, return the lifter to Powr-Grip or an authorized dealer for repair (see LIMITED
WARRANTY).
Infrequent Use
If a lifter is used less than 1 day in a 2-week period, perform the Periodic Inspection each time
before using the lifter .

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. 7 Employ the following method to test with an actual
load:
1) Place a test load with appropriate L

HARACTERISTICS
(see INTENDED USE) on a stable
support. Make sure the load is oriented in the upright position. 8
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
