(See Battery Maintenance, Page 6).
4. Verify batteries are charged.
5. Check that A.C. extension cord has been
disconnected from chassis outlet.
6. Check that all guardrails are in place and all
fasteners are properly tightened.
7. Carefully inspect the entire work platform for damage
such as cracked welds or structural members, loose
or missing parts, oil leaks, damaged cables or hoses,
loose connections and tire damage.
8. Move machine, if necessary, to unobstructed
area to allow for full elevation.
