At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.

1. Park the machine on a hard, level surface. Engage the parking brake and chock the wheels. Raise the dump body and install the body prop. Turn the disconnect switch to the OFF position.

2. Put identification marks on all lines, hoses, wires, and tubes for installation purposes. Plug all lines, hoses, and tubes to prevent fluid loss and contamination of the fluid system.
