WARNING
Spring brake chambers contain a loaded compression spring and
must be handled with extreme care. Be careful not to drop the spring

from the front or back. During removal and installation, do not use
an impact wrench on the release tool or strike any part of the unit for
any reason. Do not attempt to dismantle the spring brake chamber,
and replace the entire unit if any structural damage is evident. Failure
to comply may result in damage to equipment or possible injury or
death to personnel. Seek medical attention in the event of an injury.
