Throttle Control
The throttle (Fig. 19) is used to operate engine at various
speeds. Moving throttle forward increases engine
speed—FAST; backward decreases engine speed—SLOW.
The throttle regulates the speed of the coring head and
controls the ground speed of the traction unit.

Hour Meter/Tachometer
When the engine is off, the hour meter/tachometer
(Fig. 19) displays the number of hours of operation that
have been logged on the traction unit. When the engine is
running, it displays the speed of the engine in revolutions
per minute (rpm).
After the first 50 hours of operation and then after every
100 hours (e.g. 150, 250, 350, etc.) the screen displays
”CHG OIL” to remind you to change the engine oil. After
every 100 hours (e.g. 100, 200, 300, etc.), the screen
displays ”SVC” to remind you to perform the other
maintenance procedures based on a 100, 200, or 500 hour
schedule. These reminders come on starting three hours
prior to the service interval time and flash at regular
intervals for six hours.
Choke
To start a cold engine, close carburetor choke by moving
choke control (Fig. 19) fully forward. After engine starts,
regulate choke to keep engine running smoothly. As soon
as possible, open the choke by pulling it backward.
Manual Ground Follow Selector Switch
Rotate switch to down position to turn off the TrueCoret
feature (Fig. 19) Remove screw to access manual ground
switch.
System Reset
Press system reset switch (Fig. 19) to raise coring head if
system becomes disabled (i.e. engine out of fuel, etc.)
