Greensmaster Flex 18/21 Page 5 – 9 Electrical System
Operator Presence Switch (Optional)
The optional Operator Presence Kit for the Flex 18 and
Flex 21 uses a switch mounted on the equipment handle
that is operated by a bail. When the operator holds the
bail against the handle, the switch closes, allowing the
engine to run.
The common terminal and normally open terminal of the
switch are used for the operator presence system on the
Flex 18 and Flex 21 (Fig. 8). The normally closed termi-
nal is not used.
Testing
Using a multimeter, the operator presence switch can be
tested as follows:
1. With the bail released (away from the handle), there
should be no continuity between the two terminals used
on the Operator Presence Kit switch (Fig. 8).
2. With the bail held against the handle, there should be
continuity between the same two terminals.
Adjustment
1. Mount operator presence switch to allow switch
plunger to be depressed 0.080” (2.0 mm) when operator
presence bail is engaged.
2. Switch plunger should be fully extended when oper-
ator presence bail is released.
