11. When using the Side Drive Unit or the optional right rear drive wheel, the Rear
Drive switch (left or right) may be in one of two positions:
1. ON: drive is on and drives with the front wheel.
2. OFF: drive is off and free wheels. (For use during turns)
12. If the engine is lugging or the exhaust is exceptionally black, check the position
of the vibrator pots. It is recommended that all three vibrator pots be set at
approximately the same position. Unused vibrators should be turned off. This
reduces the hydraulic load on the engine.
13. If automatic controls cause frequent and / or large corrections, recheck grade.
Grade should be flat within 1/2" for the entire run.
14. If the grade is uneven the height cylinder could be given a sudden signal to lowĆ
er the machine a large amount (e.g. coming out of a pothole or running over
a large bump.) If the machine is not able to react fast enough, this will cause the
rear wheel to lift off the ground and may result in a loss of hydraulic power to
the steering circuit. If the rear wheel is lifted off the ground by the automatic
height control, adjust the height trim pot to reposition the wheel at grade. Then,
slowly turn the trim pot back at the original grade. If this occurs repeatedly, enĆ
sure that the grade is within specifications and there are no dips or waves.
15. To prevent the rear wheel from lifting of the ground adjust the auto height limit
switch. The switch location and adjusting procedures are outlined on page 31.
16. If the vibrator output seems low or if the travel speed seems slow, check the hyĆ
draulic pump suction hoses (from filters to pumps) for kinks.
