It also shows the folded configuration for easy storage and various height adjustments.
- Roller Head: Features two red rollers designed to allow pipes or other cylindrical materials to rotate freely, aiding in welding, cutting, or assembly tasks.
- Adjustable Shaft: The central vertical component that allows for height adjustment. It includes a 1-1/2-inch Acme fine adjustment thread for precise positioning.
- Quick-Action Lock Washer: A mechanism for fast and secure height adjustment, ensuring the shaft remains at the desired height.
- Patented Fall Guard™ Feature: Provides a 1-inch (2.5 cm) safety zone under the lock washer, preventing accidental drops during adjustment.
- Folding Base: A sturdy 1-inch square tube construction that folds for compact storage and easy transport.
- Rounded Foot Pads: Designed to provide stability and prevent damage to floor surfaces.
- Carrying Handle: Integrated for convenient portability when the unit is folded.
4. Setup
- Unfolding the Base: Place the folded jack stand on a flat, stable surface. Carefully unfold the three legs until they are fully extended and locked into position. Ensure the base is stable and does not wobble.
- Adjusting Height: Loosen the quick-action lock washer. Adjust the height of the shaft by sliding it up or down to the desired working height. For fine adjustments, use the Acme thread by rotating the shaft.
- Securing Height: Once the desired height is reached, firmly tighten the quick-action lock washer to secure the shaft in place. Ensure the patented Fall Guard™ feature is engaged correctly.
- Positioning: Place the jack stand in the desired location, ensuring it is directly under the material to be supported. For long materials, use multiple jack stands to distribute the load evenly.
5. Operating Instructions
- Loading Material: Carefully place the pipe or material onto the roller head. Ensure the material is centered and stable on the rollers.
- Material Rotation: The roller head allows for easy rotation of the material, which is beneficial for welding, cutting, or other fabrication processes. Apply gentle force to rotate the material as needed.
- Adjusting During Operation: If height adjustment is required during operation, ensure the material is temporarily secured or supported by other means before making adjustments. Always re-secure the lock washer after adjustment.
- Unloading Material: Carefully remove the material from the roller head once work is complete.
6. Maintenance
- Regular Inspection: Before each use, inspect the jack stand for any signs of damage, cracks, bends, or excessive wear on the frame, rollers, adjustment screw, and lock washer.
- Cleaning: Keep the jack stand clean and free from dirt, debris, and welding spatter. Wipe down surfaces with a damp cloth.
- Lubrication: Periodically apply a light lubricant to the Acme adjustment thread to ensure smooth operation.
- Storage: When not in use, fold the jack stand for compact storage. Store in a dry environment to prevent rust and corrosion.
- Component Replacement: If any part is damaged or excessively worn, replace it immediately with genuine Sumner parts. Do not attempt to repair damaged structural components.
