Jack service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a jack, use only identical replacement parts - refer to the Parts List on
page 8 and Assembly Diagram on page 9 of this manual. Follow instructions in the “In-
spection, Maintenance, And Cleaning” section of this manual. Use of unauthorized parts
or failure to follow maintenance instructions may create a risk of injury.
WARNING! Do not exceed the maximum lift capacity for the Bottle Jack as stated on
the product label and the specifications table. Overloading the Jack could cause serious personal injury and/or property damage.
The Bottle Jack is designed for intermittent use only. Do not use the Jack to support a
vehicle over extended periods of time. The duration of the lifting job should be kept as short
as possible. Always use jack stands to support a vehicle over an extended period of time.
Maintain labels and nameplates on the Bottle Jack. These carry important information. If
unreadable or missing, contact Harbor Freight Tools for a replacement.
Prior to using the Bottle Jack, make sure to read and understand all warnings, safety
precautions, and instructions as outlined in the manufacturer’s instruction manual for
the vehicle (or object) you will lift.
When lifting only one wheel, make sure to support the load immediately with one jack
stand (not included) placed under the side of the vehicle being lifted. Align the saddle of
the jack stand directly under the vehicle’s seam or recommended lifting point.

When lifting the entire front end or rear end of a vehicle, make sure to support the load
immediately with two jack stands. Align the saddles of the jack stands directly under the
vehicle’s frame or recommended lifting points. Also make sure the jack stands are adjusted
at the same height.
Make sure the Bottle Jack is used only on a dry, oil/grease free, flat, level, solid surface
capable of supporting the weight of the vehicle being lifted and any additional tools
and equipment.
WARNING! Do not work under the vehicle without properly supporting the vehicle with
jack stands. Make sure the load and jack stands are stable before getting under a vehicle.
Use the Bottle Jack only on vehicles whose frames have lifting points (on its seam or
frame) capable of aligning with the Saddle of the Jack.
This bottle jack is not intended for roadside use. This jack requires a flat, stable surface
to safely lift a load.
Do not use the Bottle Jack with the vehicle’s engine running. Make sure to place the
vehicle’s transmission in “Park” (if automatic) or “1st Gear” (if manual). Then set the emergency
brake, and block the tires opposite the tire being lifted.
Industrial applications must follow OSHA requirements.
Always keep hands, fingers, and feet away from all moving parts of the Bottle Jack when
applying or releasing a load. Remain clear of the vehicle being raised or lowered. People
and animals should be kept at a safe distance when using the Jack.
