Corker Maintenance

  1. Top Plate---covers the jaws
  2. Cork Pusher--moves the cork from the Tube to the jaws
  3. Cork Descent Tube- brings cork from the hopper
  4. Cork pushing Pin--drives the cork into the bottle
  5. Clamp--holds cork tube
  6. Back Plate--please note bolt just to the right of the '6'.

ALERT: BOTTLE HEIGHT ADJUSTMENT
Be sure the top of your bottle is 3/4" or less from the bottom of the white cone.
The Bottle Height is critical to operation of the corker. The most common misadjustment is having the bottle too low. This can cause the following problems which may be wrongfully attributed to another alignment element.

Brief explanation of operation.

The Cork Pusher (2) moves cork from the Tube (3) and drops the cork into the Jaws. This requires proper alignment of several elements. Here is the proper order of adjustments.

  1. Be sure the hole in the top plate is aligned with the iris of the jaws. If necessary, loosen the 6 bolts holding the top plate and move the plate to center the hole. Then secure tightly. [As a rule of thumb, the top plate should be recessed about 1/8" from the front plate.]
  2. The gap between the bottom of the Cork Descent Tube and top of Cork Pusher should be 1/4" or less. The Cork Descent Tube can be moved by carefully twisting and pulling it. Try to avoid removing the Clamp if possible. [Please note that if you are using 2" cork, the gap may need to be more than 1/4". See below.]
  3. The Cork Descent Tube must be positioned in the horizontal plane in order that the cork falls cleaning into the Cork Pusher during a cycle. Loosen Bolt # 6 to move the back plate to position the Cork Descent Tube. Please note that a moving the Top Plate (step 1) MAY necessitate moving the back plate. This is because the top plate position determines the position of the Cork Pusher which in turn dictates the position of the Cork Descent Tube.

Problems and Solutions
Please note that proper operation requires regular cleaning of the top plate and cork pusher. This may require wiping the surface free of cork dust every 2-4 hours of operation. Also, be sure to lubricate the pivot point fo the cork pusher as well as the jaws after every 8-16 hours of use.

  1. Cork does not fall cleaning into jaws on every cycle (it hangs up on lip of jaws). Move the top plate to align the hole with the jaws.
  2. Cork is dragged under the Cork Descent Tube. Cork descent tube is too high above the Cork Pusher. Lower to ~1/4" gap
  3. Cork does not drop into Cork Pusher on each cycle. The Cork Descent Tube is too far back. Loosen Back Plate Bolt (6) and move back plate forward.

Lubricating the jaws.
Push the Cork Pusher back and use a small brush to grease each of the four seams of the jaws. Run the machine ~8 times without cork (this pulls the grease into the jaws). Then run about 6 cork through the machine to remove excess grease.

Annual Lubrication: Essentially, lubricate everything that moves every year. Remove the back plate of the machine as well as the front plate (behind bottle stand). Use a good lubricant (does not need to be food grade) to lubricate all moving parts.

Machines with Vacuum or Gas have a solenoid valve. This valve can stick if the machine is not in use. Tap on the valve to help it move and then it will be fine. It is a good idea to put a couple of drops of light oil (sewing machine oil) into the valve occasionally.

2" Cork. You may need to raise the Cork Descent Tube to use 2" cork. If the Cork Descent Tube is too low, the top of the 2" cork may be caught by the tube. If this is the case, raise the Cork Descent Tube. Raise it the minimum amount required in order to avoid Problem #2 above (dragging the cork under the Cork Descent Tube.)
