responsibility of the product user to consult a body/frame repair technical manual
for full instructions.
Maintain labels and nameplates on the Auto Body/Frame Repair Kit. These
carry important information. If unreadable or missing, contact Harbor Freight Tools
for a replacement.

Stay clear of an Hydraulic Ram when using the tool. Position your body as far
away from the Ram as is practical when the Ram is under a load. It is possible
for a Ram to slip under a load, possibly resulting in serious injury and/or property
damage.
Industrial applications must follow OSHA requirements.
Before working on a vehicle, always set the parking brake and block the tires.
Never attempt a repair while the engine is running or the vehicle is moving.
Avoid off-center loads. If the Hydraulic Pump (not included) unit seems unusually hard to pump, immediately stop the operation. Adjust the Hydraulic Ram unit
to eliminate or diminish an off-center load.
For technical questions, please call 1-800-444-3353.
