INSPECTION AND ADJUSTMENT
12-2-3. Adjustment of potentiometer 1 voltage
when reverse switch operates
The moment that reverse switch turns ON/OFF can be
monitored on water spray indicator lamp in combination
meter. Water spray mode selector switch must be placed in
“AUTO”, and water spray timer switch must be turned OFF
(placed in “ ”).
①
Set starter switch to ON.
②
Move F-R lever (2) in reverse direction.
③
Adjust with nut (9) of reverse switch (3) so that water
spray indicator lamp in combination meter illuminates
when voltage reaches a value 0.080 V lower than mid-
value measured in 9-2-1.
Example:
Mid-value : 2.500 V
Voltage when reverse switch
operates
: 2.500 + 0.080 = 2.580 V
(NOTICE)
Acceptable range for voltage when reverse switch
operates is 2.575 to 2.585 V.
Reverse switch must be installed with its centerline
aligned with centerline of F-R lever cam.
④
After adjustments are made, make sure about following
points.
F-R lever cam must not push in reverse switch until
it bottoms when F-R lever is moved toward reverse
position.
F-R lever must automatically return to neutral when
F-R lever is released at a position slightly beyond
reverse switch operating point. If lever does not return
automatically, make an adjustment by loosening disc
spring tension adjusting nut (5) and tightening screw
(7). F-R lever operating force must not deviate from
standard value.
