SPECIFIC SAFETY RULES
1.
WARNING! Do not exceed the maximum PSI capacity of each Hydraulic Ram in
this Kit. Also, do not operate a Ram beyond its maximum range of travel. Exceeding
the maximum PSI and travel capacity of a Ram can cause personal injury and/or
property damage.
IMPORTANT! Refer to the “Product Specifications” Table on page 2 of this
manual to determine the maximum PSI and range of travel for each Hydraulic Ram
included in this Kit.
2.
Prior to using the Auto Body/Frame Repair Kit, make sure to read
and understand all instructions and safety precautions as outlined
in the auto manufacturer’s manual. Make sure the Auto Body/Frame
Repair Kit is fully compatible with each specific vehicle. It is beyond the
scope of this manual to discuss body/frame repair guidelines, and instead is the
responsibility of the product user to consult a body/frame repair technical manual
for full instructions.
3.
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.
4.
Use the right product for the job. There are certain applications for which this
product was designed. Do not use this product for a purpose for which it was not
intended. Never use this item to raise or move a vehicle.
5.
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.
6.
Industrial applications must follow OSHA requirements.
7.
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.
8.
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.
SKU 94681
For technical questions, please call 1-800-444-3353.
Page 9.
Keep the Hose Couplers protected when the Hydraulic Rams are not in use.
Dust Caps are included for all Hose Couplers and should be screwed in when not
in use to keep the internal mechanisms of the Rams clean.
10.
WARNING! Prior to using the Auto Body/Frame Repair Kit, make sure to read
and understand all instructions and safety precautions as outlined in the Hydraulic
Pump (not included) manufacturer’s manual.
11.
The results you achieve with these tools will depend upon your skills and experience at using tools of this type. Harbor Freight Tools is not responsible
for damage to vehicles caused by misuse of these tools.
12.
WARNING! This product will exert thousands of pounds of force when in use
and can be dangerous. Use extreme caution when using this product.
13.
Use compressed hydraulic fluid only. Do not use any other power source or fluid
to operate this product.
14.
WARNING! The warnings and cautions discussed in this manual cannot cover
all possible conditions and situations that may occur. It must be understood by the

Refer to instructions provided with pump, hoses, and fittings for proper hydraulic
line purging, preparation, and connection procedures.
OPERATING INSTRUCTIONS
WARNING! Before starting work, read and thoroughly understand all warnings and precautions in this manual and all documentation provided with the hydraulic pump
and hoses used.
Product Overview:
The Auto Body/Frame Repair Kit is designed for bending frames and repairing
dents in vehicle body panels. In most cases, the Push and Pull Hydraulic Rams in
this Kit will only be capable of returning vehicle body and frame parts to their approximate, original position. Additional work may be required to completely repair
the vehicle part.
The Hydraulic Push Rams:
1.
Included in this Kit are five Hydraulic Push Rams. The larger Push Rams are used
in larger spaces where greater force is needed and where there is sufficient room
to operate. The smaller Push Rams are used in tighter spaces where less force is
required. (See Figure B.)
2.
The Push Rams require a solid, non-movable base directly across from the damaged area and in line with the direction the damaged area needs to be bent. When
positioning the Push Ram, place a block of wood or other material behind the base
of the Push Ram and on the side that is to be bent for protection and to spread the
Push Ram pressure over a greater area. (See Figure B.)

For technical questions, please call 1-800-444-3353.
Page 2.
The Hydraulic Pull Rams may be used in either horizontal or vertical positions.
The Hooks will turn to accept hooking from different angles. Hook one end of the
Pull Ram to the object to be moved and the other end of the Pull Ram to a stable,
unmovable base. A chain or strap may be used on either end to provide a hooking
surface. Make sure the chain or strap is rated to support the pulling weight.
