Check Operation of Interlock Switches
CAUTION
Do not disconnect interlock switches. They are
for the operator’s protection. Check the opera-
tion of the interlock switches daily for proper op-
eration. Replace any malfunctioning switches
before operating the machine.
Interlock switch operation is described in the Traction
Unit Operator’s Manual. The Groundsmaster 3280−D
and Groundsmaster 3320 are equipped with a Standard
Control Module which monitors interlock switch opera-
tion. Information on this Module is described in the Trac-
tion Unit Operator’s Manual and in the Component
Testing section of this Chapter. Testing of individual in-
terlock switches is included in the Component Testing
section of this Chapter.
