B. HYDROSTATIC DRIVE SYSTEM
ACE: AUTOMATICALLY CONTROLLED ENGINE-
1. Speed ranges are selected by a red (decrease speed range) and green (increase speed range) electronic
switch mounted on the hydrostat handle (fig. 4.40-1, item A). The lower the setting, the higher the torque,
but the lower the speed.
2. Increase the engine one bump to gain RPM of 1800 with the throttle switch (fig. 4.40-2). More RPM will be
gained as you move the hydrostatic handle forward.
3. To move forward, slowly push the hydrostatic lever forward. The farther the control lever is moved, the
faster the sprayer will travel and the RPM ‘s will increase (fig. 4.40-3). To stop, slowly pull the lever to the
“N” neutral position.
4. To reverse the machine, slowly pull the hydrostatic lever back. To stop, slowly push the lever to the “N”
neutral position.
5. Before turning off the engine, reduce engine speed and allow the engine to idle at least three minutes.
NOTE:
Machine will not shift down until highest
speed of desired range is met.
