Toro Dingo 320-D Operator's Manual page 18

Move the speed selector lever to the slow (turtle) position
to set the auxiliary hydraulics to high speed and the
traction drive, loader arms, and attachment tilt to low
speed.
Warning
If you move the speed selector lever while the
traction unit is in motion, the traction unit will
either stop suddenly or accelerate quickly. If you
operate the traction unit with the speed selector
lever in an intermediate position, the traction unit
will operate erratically and may be damaged. You
could lose control of the traction unit and injure
bystanders or yourself.
Do not move the speed selector lever when the
traction unit is in motion.
Do not operate the traction unit when the speed
selector is in any intermediate position (i.e., any
position other than fully forward or fully
rearward).
Hour Meter
The hour meter displays the number of hours of operation
that have been logged on the traction unit.
After 50 hours and every 75 hours thereafter (that is at 50,
125, 200, etc.) the hour meter displays SVC on the lower
left side of the screen to remind you to change the oil and
perform the required maintenance. After every 400 hours
(400, 800, 1200, etc.), the hour meter displays SVC on the
lower right side of the screen to remind you to perform the
maintenance procedures based on a 400 hour schedule.
These reminders come on starting three hours prior to the
service interval time and flash at regular intervals for six
hours.
Flow Divider Control
The traction unit hydraulics (i.e., the traction drive, loader
arms, and attachment tilt) work on a separate hydraulic
circuit from the auxiliary hydraulics for powering
attachments; however, the two systems share the same
hydraulic pumps. Using the flow divider control (Fig.
14), you can vary the speed of the traction unit hydraulics
by diverting hydraulic flow to the auxiliary hydraulics
circuit. The flow divider allows you to divide the flow of
fluid in varying degrees to slow the traction unit. Thus,
the more hydraulic flow you divert to the auxiliary
hydraulics, the slower the traction unit hydraulics will
move.

3. 12 o'clock position
Move the flow divider control to the twelve o'clock
position to provide maximum speed to the traction unit
hydraulics.
Use this setting for fast operation of the traction unit.
Move the flow divider control between the twelve
o'clock and nine o'clock positions to slow the traction
unit hydraulics and fine tune the speed.
Use a setting in this range with attachments with
hydraulics where you need to both run the attachment
and move the traction unit hydraulics, such as the
auger, boring unit, hydraulic blade, and tiller.
Move the control to the nine o'clock position to
transfer all hydraulic flow to the auxiliary hydraulics
of the attachment.
In this setting, the traction unit hydraulics will not
work. Use this setting with hydraulic attachments that
do not required the traction unit hydraulics. There are
currently no attachments that require the nine o'clock
position; however, the trencher does work best if you
set it close to nine o'clock so that the traction unit will
creep slowly when trenching.
Note: The flow divider control can be fixed in place by
turning the knob on the control clockwise until it contacts
the dial (Fig. 14).
