WARNING
Ensure that air pressure in brake lines is drained to 0 psi (0 kPa) prior to replacing brake
chambers. If air pressure is not released, parts and lines could blow off and harm personnel.
Air tanks have more than 30 psi (207 kPa) pressure in them. Do not drain air tanks with any
part of body in air spray path. Skin embolisms and or debris in eyes can occur from released
pressure. Failure to comply may result in injury or death to personnel.
WARNING
Do not remove air chamber prior to compressing brake spring with caging bolt. The brake
spring is under extreme pressure. Failure to comply may result in injury or death to personnel.
WARNING
Do not attempt to disassemble brake chambers. Brake chambers contain springs under great
pressure. Failure to comply may result in injury or death to personnel.
CAUTION
Equipment may be damaged by foreign matter if hoses, tubes, and connectors are not
plugged and capped when removed.
