The bucket must be in the roll back position and the bottom of the bucket must not be more than 305 to 457 mm (12 to 18 inches) off the surface.

Adjust the position of the bucket so that the front edge is lower than the back. Bucket teeth will help you dig in this type of operation. Move the machine into the digging area with the transmission in 1st gear and the engine speed at full throttle. Lower the bucket to the ground. When the bucket is at the correct depth, level the bucket and continue to move forward. TRIM THIS EDGE

When the bucket is full, roll the bucket back. There is lost time when you push material in front of the bucket.

Stock Piles Make sure the bottom of the bucket is level. Move the machine forward and down shift just as the bucket makes with the material. When the speed of the machine starts to decrease, push in the downshift button on the transmission control lever or the loader control lever or push the left brake pedal, raise the loader and roll back the bucket.

Loading Trucks Be very careful when you load trucks. Raise the load and move the machine toward the side of the truck. Use the right brake pedal to slow the machine and use the left brake pedal to stop the machine. As you move the load toward the truck, use the loader height control to automatically position the bucket at the correct height. After you dump the load, use the returnto-dig to position the bucket for the next cycle (see bucket height control and return-to-dig in this manual for adjustment). NOTE: Push down the left side of the Declutch Switch and the left brake pedal to get maximum power for the loader (see declutch switch in this manual).

WARNING: When you operate the machine, keep the loader bucket as low as possible. This low position gives better balance and permits you to see more clearly. If the bucket is full and you move the machine over ground that is rough or surfaces that can cause the machine to slide, always operate at slow speed. If you do not use this procedure, the machine can go out of control and roll-over. SA041 78
