PROdUct deScRIPtIOn
This Service Jack is designed to lift, but not support, one end of a vehicle. Immediately after lifting, loads must be
supported by a pair of appropriately rated jack stands. This service jack has a unique feature that provides fast, no
load lifts to the jacking point, at which time it lifts in approximately 0.75 ~ 2" increments.
!
NEVER use hydraulic jack as stand-alone device. After lifting, immediately support the lifted vehicle with
a pair of appropriately rated jack stands. NEVER place ANY portion of your body beneath the vehicle when
lifting OR lowering!
