Use the following procedure to access the hopper clean-out area:
1. Turn the main power off, remove the line fuses, and tag the machine as out of
service.
2. Unscrew the hopper clean-out interlock screw. Back the screw out as far as it will go.
When unscrewed, the interlock will be captive on the door to prevent loss.

hold the door with one hand to prevent it from falling.

provided in the upper lip of the door to prevent pinched fingers when the door
touches the rear panel.

2. Tighten the interlock screw as far as it will go.
