Tip For TL470 Model
Do not use the bucket as a breaker or pile driver. It is
better to excavate hard or rocky ground after breaking it
with other equipment. This will reduce damage to the
excavator.
Do not move the excavator while the bucket is in the
ground.
Dig only by moving the boom and arm toward the
excavator.
Do not back dig (digging by moving the boom and arm
away from the excavator). Damage to the quick coupler
and attachments can occur.
