1. Product Overview
The PanaVise 309 Portable General-Purpose Vise Combo is designed for versatile workholding tasks. This combo includes the Model 366 wide-opening head, Model 305 low-profile base, and Model 308 five lb. weighted base mount. It is engineered to provide stability and portability, allowing for use in various locations.
The wide-opening vise head accommodates a diverse range of objects, including circuit boards, coils, tuners, PC boards, carburetors, water pumps, and other large items. By reversing the jaw pads, the vise can securely hold delicate cylindrical objects. The low-profile base facilitates working closer to the bench surface and offers precise control through a single knob, enabling movement across three planes: 90° tilt, 360° turn, and 360° rotation. The cast-iron base mount enhances stability and portability.

2. Setup Instructions
The PanaVise 309 combo typically arrives partially assembled. Follow these steps for complete setup:
- Unpack Components: Carefully remove all components from the packaging. Verify that you have the Model 366 vise head, Model 305 low-profile base, and Model 308 weighted base mount.
- Attach Base to Mount: Place the Model 305 low-profile base onto the Model 308 weighted base mount. Align the screw holes. Secure the base to the mount using the provided screws and a suitable screwdriver. Ensure all screws are tightened firmly but do not overtighten.
- Install Vise Head: Insert the stem of the Model 366 vise head into the receptacle on the Model 305 low-profile base. Tighten the adjustment knob on the base to secure the vise head in place.
- Adjust Jaw Pads: The Model 366 vise head comes with ribbed, neoprene jaw pads. These can be reversed to accommodate different object shapes. For flat objects, use the ribbed side. For delicate cylindrical objects, reverse the pads to utilize the V-groove side.

3. Operating Instructions
The PanaVise 309 offers flexible workholding capabilities. Follow these guidelines for effective operation:
3.1 Securing Workpieces
- Opening/Closing Jaws: Turn the handle on the vise head to open or close the jaws. Place your workpiece between the jaw pads.
- Tightening: Turn the handle clockwise to tighten the jaws around the workpiece. Apply sufficient pressure to hold the object securely without causing damage. The neoprene pads provide a firm grip and insulation.
- Holding Cylindrical Objects: If working with delicate cylindrical objects, ensure the jaw pads are reversed to expose the V-groove side. This provides a more stable and secure hold.

3.2 Adjusting Vise Position (3-Plane Movement)
The Model 305 low-profile base allows for precise positioning of your workpiece:
- Loosen Adjustment Knob: Locate the single adjustment knob on the side of the Model 305 base. Turn it counter-clockwise to loosen the ball joint mechanism.
- Tilt (90°): Tilt the vise head forward or backward up to 90 degrees to achieve the desired angle.
- Turn (360°): Rotate the entire vise head horizontally 360 degrees around the base.
- Rotation (360°): Rotate the vise head itself 360 degrees along its axis.
- Secure Position: Once the desired position is achieved, turn the adjustment knob clockwise to firmly lock the vise head in place.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your PanaVise 309.
- Cleaning: After each use, wipe down the vise with a clean, dry cloth to remove dust, debris, and any metal shavings. For stubborn grime, a mild cleaner can be used, ensuring to dry thoroughly afterward.
- Lubrication: Periodically apply a light machine oil or silicone spray to the screw mechanism of the vise jaws and the ball joint of the base. This will ensure smooth operation and prevent corrosion. Avoid over-lubricating the jaw pads.
- Inspection: Regularly inspect all screws and fasteners for tightness. Check the neoprene jaw pads for wear or damage. Replace worn pads to maintain optimal grip.
- Storage: Store the vise in a dry environment to prevent rust and corrosion.
5. Troubleshooting
Refer to the following common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Vise jaws are stiff or difficult to turn. | Lack of lubrication; accumulation of debris. | Clean the screw mechanism and apply a light machine oil. |
| Workpiece slips in jaws. | Jaws not tightened sufficiently; worn or dirty jaw pads; incorrect pad orientation for cylindrical objects. | Ensure jaws are tightened properly. Clean or replace worn jaw pads. Reverse pads for V-groove if holding cylindrical items. |
| Vise head does not hold position after adjustment. | Adjustment knob on base is not tightened enough. | Tighten the adjustment knob firmly clockwise to secure the ball joint. |
| Base feels unstable. | Base not properly secured to the weighted mount; uneven work surface. | Check that the base is securely fastened to the weighted mount. Ensure the work surface is flat and stable. |
