   consult a body/frame repair technical manual for full instructions.

4. Wear ANSI-approved safety goggles and heavy-duty work gloves during setup and use.

5. Stay clear of Rams during operation. Position body as far away as practical when Ram is under load. Ram can slip suddenly, causing injury.

6. Keep work area clean and well-lit.

7. Keep bystanders out of the work area.

8.  Do not use when tired or when under the influence of alcohol, drugs, or medication.

9.  This product is not a toy. Do not allow children to play with or near this item.

13.  Read and understand Hydraulic Pump instructions before use.

14.  Before working on a vehicle, set the parking brake and block the tires.

ASSEMBLY INSTRUCTIONS

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product.
Refer to instructions provided with pump, hoses, and fittings for proper hydraulic line purging, preparation, and connection procedures.

OPERATION INSTRUCTIONS

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product.
Note: 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.
Pushing

1.  Use the larger Push Rams where greater force is needed and where there is sufficient room to operate.
2.  Use the smaller Push Rams where less force is required.
3.  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.
   Note: 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.

Pulling

1. Use the larger Pull Ram where greater force is needed and where there is sufficient room to operate.
2.  Use the smaller Pull Ram where less force is required.
3.  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.
4.  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.
   Note: The Hydraulic Pull Rams may be used in either horizontal or vertical positions. The Hooks will turn to accept hooking from different angles.

INSPECTION, AND CLEANING MAINTENANCE,

Procedures not specifically explained in this manual must be performed only by a qualified technician.

WARNING
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.

1. BEFORE EACH USE, inspect the general condition of the tool. Check for:
