OPERATIONAL PERFORMANCE TEST / Wheel Loader Test BUCKET LEVELNESS Summary: Left and right inclinations of the bucket are checked in order to prevent uneven wear of the cutting edge of the bucket. Preparation: 1. Place the unloaded base machine on a horizontal bed on rhe ground. (In case a bed is not available, place it on a horizontal flat concrete on the ground. Deal with the measurement values as guide lines.) 2. Adjust the tire air pressure to the designated value. 3. Have the bucket bottom contact the ground hori- zontally. Measurement: 1. Have the bucket bottom float slightly above the bed. 2.
Measure the vertical distance from the bed and the bottom face of the cutting edge on the left and right ends, and confirm the difference. 3. Make measurement three times, and determine the measurement value by obtaining their mean values.
