Installing the Snowblower
Note: The following procedures are for models with an auxiliary hydraulic controller.
 |
Do not use an auxiliary override with this work tool. The work tool can be fully powered even if the arm bar is raised and the operator has exited the cab. Severe injury or death could occur. Do not exit the cab until the work tool and the host machine have been shutdown and the parking brake is engaged. |
 |
|
Improper attachment of work tools could result in injury or death. Do not operate this machine until you have positive indication that the coupler pins are fully engaged. To check for engagement: 1. Keep the work tool close to the ground. 2. While the lift arms are fully lowered, visually inspect the quick coupler to ensure that the coupler pins are fully extended through the corresponding holes of the work tool mounting bracket. |

Note: The controls for the rotation of the discharge chute and the deflector are located on the control device for the Snowblower. The control device for the Snowblower requires a 12 volt receptacle which must be installed by your Caterpillar dealer. If your machine is not equipped with a receptacle, contact your Caterpillar dealer for installation. Refer to Special Instruction, REHS1182, "Providing a Power Source to the Control Device for Snowblowers", Special Instruction, REHS2413, "Providing a Power Source to the Control Device for Snowblowers (B-Series SSL/MTL)", or Special Instruction, REHS2795, "Providing a Power Source to the Control Device for Snowblowers (904B Compact Wheel Loader)" for the correct procedure.

The 12 volt receptacle will be located on the right side or left side of the machine. | |
Note: If the machine is not equipped with a cab that is enclosed, Caterpillar recommends the use of a flying object guard. If the machine is equipped with an enclosed cab, operate the machine with the cab door in the CLOSED position.
- Position the Snowblower on a level surface. Move the hydraulic lines for the Snowblower and the electrical lines for the Snowblower away from the mounting bracket.
- Disengage the coupler pins on the quick coupler of the host machine. Refer to the Operation and Maintenance Manual of the host machine for details on disengaging the coupler pins.
- Enter the host machine.
- Close the cab door, if equipped.
- Fasten the seat belt.
- Lower the armrest, if equipped.
- Start the engine.

- Route the hydraulic lines and the electrical lines for the control device for the Snowblower through the hose guide on the host machine. Ensure that the quick connect couplers for the hydraulic hoses are clean on the work tool and the machine. Connect the auxiliary hydraulic lines to the host machine. Twist the collars of the quick connect couplers for one quarter of a turn in order to secure the hydraulic connections.
Note: It is necessary to release the hydraulic system pressure of the host machine before you connect the hydraulic lines of the work tool to the machine. Refer to the Operation and Maintenance Manual of the host machine for details.
