CENTRAL COMMAND I
CENTRAL COMMAND I
The Central Command I system refers to all of our equipment manufactured utilizing a Curtis
speed control system. This system was used an all our equipment with a speed controller
from 1994 to 2002. In 2002 Central Command II was released and while some machines
were migrated to Central Command II others retained the Central Command I system.
IDENTIFICATION
This Central Command I system can be identified on scrubbers by
the presence of a red segmented down pressure gauge accompa-
nied by a Curtis Instruments Battery gauge. The model 4700 and
48 sweepers still use the Central Command I control system as
does the Model 200 burnisher.
