Assembly

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

Note: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the end of this manual.

1. Take a Post and face the ratchet edge toward the front of the Base. The Pawl is on the front.
2. Use a hex wrench (sold separately) to loosen the Screw (5) so that it doesn’t interfere with the Post sliding into the slot. Lift the Handle and lower the Post into the Base. Make sure it is completely lowered. See Figure A. CAUTION! Be alert to pinching hazard when lowering the Post.
3. To secure the Post, tighten the Screw (5) shown in Figure 2. WARNING! Before using the Jack Stands, make sure the Post cannot be pulled up and out of the Base.
4. Repeat Steps 1 through 3 with the other Jack Stand.

Operating Instructions

CAUTION
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.
WARNING!
Use as matched pair to support one end of a vehicle only.

Supporting a Vehicle

1. Make sure the vehicle does not exceed the capacity of the Jack Stands. Note: Check that the weight is evenly distributed between the Jack Stands. You must evenly distribute the weight or the Jack Stands may fail, causing severe injury or death. Only apply the load vertically.
   WARNING! If a vehicle drops on the Jack Stands (even if it is under the weight capacity limit), the principle
   of “dynamic loading” takes affect. The force of the weight falling may cause the Jack Stands to fail. A vehicle weighing much less than the Jack capacity may cause the Jack Stands to fail if dropped on them.
   Note: Do not move the Handle when the Jack Stands are supporting a vehicle. The shear pin is designed to shear in the event the user attempts to move the Handle while supporting weight. If the pin shears, do not use the Jack Stands again until the shear pin is replaced by a qualified technician.

2. Examine Jack Stands for cracks or damage before each use. Do not use if even a minor crack, bend, or other damage/deformation appears. Discard Jack Stand if damaged or deformed.

3. Raise the Handle on each Jack Stand to completely lower the Post.

4. If your are raising only one end of the vehicle, block the tires that remain on the ground.

5. Following the instructions in your floor jack manual, raise your vehicle to just above the minimum height of your Jack Stands.

6. Slide your Jack Stands to the proper position points referred to in the vehicle owner’s manual. Make sure the Jack Stands are on the same point on each side of the vehicle. Move the Handle up, and raise the Jack Stands until they are just below the jack contact point on the vehicle. Center the load on the Saddle of the Post. Release the Handle so that ratchet catches on the Pawl. Gently lower the vehicle with the floor jack. It may drop down a very small amount until the ratchet catches on the Pawl. Repeat on other side.
   WARNING! Set both the Jack Stands to the same height.

7. Determine if the vehicle is stable. If not, raise the vehicle and reposition the Jack Stands.

Removing the Jack Stands

1. Raise the vehicle with a floor jack to take the load off of the Jack Stands.
2. Raise the Handle on the Jack Stands and lower the Posts.
3. Remove the Jack Stands. Use the floor jack to safely lower the vehicle to the ground.

WARNING! Do not use Jack Stands as a permanent stand for the vehicle. Use them only while making repairs, then immediately lower vehicle to the ground.

Maintenance and Servicing

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

1. Periodically clean the bottom of the Bases and top of Posts of any dirt, grease, or debris.
2. Before each use, inspect the general condition of the Jack. Check for broken, cracked, or bent parts, loose or missing parts, and any condition that may affect the proper operation of the product. Do not use damaged equipment. Discard Jack Stand if damaged or deformed.
