carefully before use.

• Never exceed the jack’s
rated capacity.

• Jack should only be used on
a solid level surface.

• Never work underneath the
vehicle without the use of
additional safety support
devices (Ex: Rated jack
stands).

• Do not disassemble.
Disassembly may result in
malfunction or injury.
