Removal Procedure
- Park the machine on a hard, level surface. Lower the scraper bowl to the ground and engage the parking brake. Chock the wheels in order to prevent the machine from moving.
- Put identification marks on all lines, hoses, wires, and tubes for installation purposes. Plug all lines, hoses and tubes. This helps prevent fluid loss and contamination of the oil system.
 |
At operating temperature the implement hydraulic oil tank is hot and under pressure. Hot oil can cause burns. To prevent possible injury, release the pressure in the implement hydraulic system before hydraulic lines or components are disconnected or removed. |
