GUARD 5V9029 - Caterpillar

The suspension system may drop the machine suddenly, leaving no clearance between the axle housing, main frame, tires and mud guards. Working in these areas can result in personal injury or death by crushing. Stay clear until the engine is stopped and the suspension is lowered to the service position.
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. Remove the breather filter cap only when the engine is stopped and the breather filter cap is cool enough to touch. Slowly loosen the breather filter cap to release any pressure in the hydraulic tank. Be cautious of hot hydraulic oil when any lines are disconnected in the hydraulic system.
Put identification on all lines, hoses, wires and tubes for installation purposes. Cap and plug all lines, hoses and tubes to prevent foreign material from entering the system.
