DISCONNECT S ERVICES
WARNING!
WORKING WITH THE ELECTRICAL AND AIR SERVICES REQUIRED FOR VMC
CAN BE EXTREMELY HAZARDOUS. MAKE SURE THAT PRESSURE HAS BEEN
REMOVED FROM THE AIR LINE BEFORE YOU DISCONNECT IT FROM THE
MACHINE. SIMILARLY, THE ELECTRICAL POWER MUST BE OFF AND STEPS
MUST BE TAKEN TO ENSURE THAT IT WILL NOT BE TURNED BACK ON
WHILE YOU ARE WORKING WITH IT. IN MOST CASES THIS MEANS TURNING
OFF A CIRCUIT BREAKER IN A PANEL AND THEN LOCKING THE PANEL DOOR.
HOWEVER, IF YOUR CONNECTION IS DIFFERENT OR YOU ARE NOT SURE
HOW TO DO THIS, CHECK WITH THE APPROPRIATE PERSONNEL IN YOUR
ORGANIZATION OR OTHERWISE OBTAIN THE NECESSARY HELP BEFORE
YOU CONTINUE.
1. Disconnect the air supply line at the pressure regulator (below the electrical panel on the back of
the machine).
2. Turn off the electrical power to the machine at its source (see the caution at the beginning of this
section).
3. Set the main switch on the machine (upper right of the electrical panel on the back of the machine)
to OFF.
4. Release the three latches along the edge of the panel door and open the door.
5. Using a screwdriver to release the terminals, disconnect the three electrical leads to the terminals
behind the main switch and the adjacent ground-bus connection. Pull the wires out of the top of the
panel box and secure them safely.
6. Remove the air-filter screen mounted toward the bottom on the outside of the panel door (lift it up
and then pull the bottom edge out). Clean it with compressed air if necessary.
7. Place the air-filter screen, along with the manuals and other documentation, inside the panel at the
bottom left.
8. Set the main switch to OFF (rotate the shaft that engages the handle on the panel door counter-
clockwise as far as it will go and then let it snap into the OFF position). Also, set the main switch
handle on the panel door to OFF. (Both the handle and the switch must be set to OFF before the
door can be closed). Close the door and lock the latches.
