ELECTRICAL MAINTENANCE
Have a qualified electrician do maintenance and trou-
bleshooting work. Be sure to disconnect the unit from the
input power supply before any work is done.
--------------------------------------------------------------------
Circuit protection is available on machines with a Low/High
mode switch. Machines built after April, 1999 are reset by
switching the main power switch. Machines with a Low/High
mode switch built before April, 1999 use a separate circuit
breaker.
First switch the main power switch off, then on again. If opera-
tion is not restored, check input power. If input power is avail-
able, disconnect from input power and reset circuit breaker by
first removing rear cover and then resetting breaker.
Check brushes after 1000 hours of run time. Brushes worn to
3/8" long should be replaced. There are two brushes required
per motor; two motors per X-Tractor 1GC.
A. Removal of Rear Cover:
1. Remove the canister and case front assembly.
2. Using an adjustable wrench, hold the compressed air fitting at
the rear of the machine. Rotate the cleaning device inside the
machine to loosen the fitting. Leaving the cleaning device in
the machine, unscrew the fitting from the cleaning device and
set aside.
3. Using a Phillips head screwdriver, remove the screws that
hold the rear cover to the case sides along the perimeter. It is
not necessary to remove the screws from the face of the rear
cover.
