Inadmissible work procedures
Working with swivel force
• Do not use the swivel force of the upper carriage to tear down walls or
to create level surfaces.
• Never ram the attachment into the ground when swiveling the upper
carriage.
➥ This can damage the machine or the attachment.
Working with travel force
• Never ram the attachment into the ground to dig when traveling.
➥ This can damage the machine or the attachment.
Retracting the attachment
• When retracting the attachment, ensure that it does not touch the
stabilizer blade.
Avoid impact during operation to avoid damage to the excavator
bucket and machine components.
• Do not suddenly drop the bucket to increase penetration, break
material, or compact material.
➥ Working this way can greatly reduce the machine’s service life.
