Background

The front door of the Lotem should open and close easily. There should also be 3 millimeters of clearance between the bottom of the door and the top of the upper front panel. If the door does not open easily, or if there is too little clearance, the front door locking assemblies must be adjusted.

Procedure

1. Open the front door.
2. Remove the right and left upper front side panels.
3. Remove the upper front panel.
4. Adjust the arm of right and the left locking assembly:
   1. Open the adjusting nut (shown below) by turning it 360° twice—it should move toward the center of the machine.
   2. Close the locking hex nut (shown below) by turning it—it should move toward the outside of the machine.



5. Adjust the position of the right and left roller plate:
   1. From inside the chassis, loosen the two plate securing screws (shown below from inside the machine) and press the plate downward as far as it will go.
      Note: Notice the semi-circular notch on the top of the roller plate.

   

   2. Close the front door and, using a flashlight, inspect the area of the semi-circular notch on the plate.
   3. Move the plate until the front door locking roller (shown in the picture below) is centered in the semi-circular notch and 2.5 mm away from its edges, as shown in the following drawing.

   

   

   4. Hold the plate in place and tighten the two plate securing screws.
6. Place the upper front panel back on the Lotem. Do not secure it in place.
7. Close the front door and, using a feeler gauge, verify that there is at least 3 mm clearance between the bottom of the front door and the top of the upper front panel at any given point. If there is not enough clearance, adjust the position of the right and left locking assemblies:
   1. Open the front door and remove the upper front panel.
   2. Use a pen or pencil to trace the shape of the locking assembly on the chassis (as represented by the dotted line in the picture below).
      Note: Do not use an erasable marker.

   

   3. From inside the chassis, loosen the four locking assembly securing screws (circled in the picture below)—do not remove them.

   

   4. Raise the locking assembly 1 mm.
      Tip: Use the line you drew in step b as a reference—the bottom of the assembly should be 1 mm above the line you drew, and the side of the assembly should be aligned to it, as shown below.

   

   5. From inside the chassis, tighten the four locking assembly securing screws.
   6. Repeat steps a through e on the other side.
   7. Repeat steps 6 and 7. If the door does still not close properly, check the roller plate to verify whether the newer version, which has a larger semi-circular notch, is installed (shown below).

   

   If the newer plate is not installed, remove the older plate, install the newer one, and repeat steps 5 through 7.

8. Secure the upper front panel in place using the four screws and lock washers that you previously removed.
9. Replace the right and left upper front side panels and close the front door.
10. From the PC controller, open the front door and verify that it opens properly.
