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.
Do not remove air chamber prior to compressing brake spring with caging bolt. The brake spring is
under pressure. Failure to cage the chamber could cause serious injury or death to personnel.
Do not attempt to disassemble brake chambers. Brake chambers contain springs under pressure.
Attempting to disassemble brake chambers could result in serious injury or death to personnel.
Equipment may be damaged by foreign matter if hoses, tubes, and connectors are not
plugged and capped when removed.
Tag and mark all air lines, fittings and connector prior to removal.
Cap and plug air lines and connectors after removal.
