Maintenance Instructions
ADJUSTMENTS/ELECTRICAL SYSTEM
Adjusting the Grass-Pak
®
Switch
3. If adjustment is required, hold the Grass-Pak
®
switch mount bracket firmly, grasp the switch and
bracket and bend it down. Adjustments should
be done in very small increments checking the
measurement each time until the recommended
measurement is achieved. This measurement is
applicable to all catcher box sizes.
NOTE: It will not be possible to adjust the switch to
give a signal at the precise instant the catcher is full
for a wide variety of mowing conditions. For exam-
ple, wet heavy grass will fill the catcher differently
than dry fluffy grass, causing the signal to come on
a little sooner or later than usual. Primarily, the
switch should be adjusted to give the “full” signal with
a little advance warning before overfilling and
clogging of the grass delivery chute begins (regard-
less of mowing conditions).
ELECTRICAL SYSTEM
For troubleshooting, refer to Wiring Diagram.
IMPORTANT: For Model MTEFI, an illuminated En-
gine Service Light on the control panel means that a
fault has been detected in the electrical/fuel system.
Contact an authorized Kohler Service Dealer to di-
agnose the fault.
IMPORTANT: Disconnect both battery cables be-
fore unplugging any wiring connectors or making re-
pairs on the electrical system.
IMPORTANT: Disconnect the battery cables before
unplugging and removing the instrument panel.
Circuit Breakers
A master circuit breaker is mounted on a bracket be-
hind the battery. The circuit breaker may have either
the manual or automatic reset function -- both types
have been used. See Circuit Breaker Location
