MACHINE OPERATIONS AND CONTROLS

The operation speed is determined by the terrain, ground condition, load volume, type of load, and how large
the jobsite is.
Keep the engine speed almost maximum during the operation. Use the 1st or 2nd in the speed range for opera-
tion.
Use the 3rd or 4th in the speed range when traveling without load.
