OPTIONS, ATTACHMENTS 31.2 ADJUSTING LOAD MEASUREMENT POINTS To improve the position when measuring, perform the following operation. 1. Tilt the bucket fully back and raise the boom until the arm is in the horizontal position (boom height “H”). 2. Watch the indicator on the proximity switch, which is located on the right boom. Adjust the sensor plate as follows: A. With the bucket on the ground, the indicator should light up. B. With the boom horizontal (boom height H), the indicator light should be off. 3. After performing the calibration, load the bucket with a known weight. If the load displayed on the meter is too low, raise the boom height setting.
If the load displayed on the meter is too high, lower the boom height setting. Adjust the calibration again. REMARK The mounting position of the proximity switch and sensor plate is set, per the illustration at the right. WA450-3MC 5-18
