Operation:
• Raise or lower boom to appropriate height and open grapple for loading material
from stockpile.
• Align telehandler with face of stockpile and drive slowly and smoothly into pile to

Equipment Damage Precautions
• Except for lifting or dumping a load, the boom must be fully retracted for all
bucket operations.
• Do not corner-load bucket. Distribute material evenly within the bucket. Bucket
capacity charts are for evenly distributed loads only.
• Do not use bucket as a lever to pry material. Excessive prying forces could
damage bucket or machine structure.
• Do not attempt to load material which is hard or frozen. This could cause severe
damage to quick attach or machine structure.
• Do not use bucket for "back dragging." This could cause severe damage to quick
attach.
