    Cleaning the Machine

    Maintenance Service IntervalMaintenance Procedure
    After each use
  • Clean the machine.
    		•

    Important: Do not use brackish or reclaimed water to clean the machine.

    • After daily use, thoroughly wash the machine with a garden hose (without a nozzle) to avoid contamination and seal and bearing damage due to excessive water pressure.

      Note: Use a brush to help remove thick layered, dried, or compacted dirt and debris.

    • Use a mild detergent to clean the covers.

    • Inspect the machine for damage, leaking oil, and component wear.

    • After cleaning the machine, grease all drive lines and roller bearings; refer to Greasing the Attachment.

    Installing the Fraise Blades

    For the replacement of the fraise blades, it is necessary to point the fraise blades facing to the left or the right to obtain a correct overlap (Figure 36).

    To clarify the correct position, certain rotor plates have a notch cut into them.

    Note: Ensure the knife edge rests against the rotor plate.

    • Install the fraise blades with a notch facing to the left side of the machine.

    • Install the fraise blades without a notch facing to the right side of the machine.

    Installing Optional Scarifying Knives

    This machine is equipped with fraise knives but you can also use it with scarifying knives for scarifying the subsoil.

    You can set the distance between the scarifying knives at the following 4 positions:

    • 25 mm (1 inch)

    • 50 mm (2 inches)

    • 75 mm (3 inches)

    • 100 mm (4 inches)

    In order to avoid imbalance, weights are used for the spacing of 50 mm (2 inches), 75 mm (3 inches), and 100 mm (4 inches).

    Use the tables below to select the spacing. The letter W in the tables indicates where the weights are installed and the letter S indicates where the knives are installed.

    Note: If there is no letter in the table cell, this indicates that nothing is installed at that position.

    Storage

    Storage Safety

    • Before adjusting, cleaning, storing, or repairing the machine, park the it on a level surface; engage the parking brake of the traction unit; shut off the engine; remove the key; and wait for all movement to stop before leaving the traction unit.

    • Store the machine on the front and rear rollers positioned on a firm, level surface so that it does not sink or roll away.

    • Store the machine away from areas of human activity.

    • Do not allow children to play on or around the stored machine.

    Preparing the Machine for Storage

    Important: Do not use brackish or reclaimed water to clean the machine.

    When the machine is stored for a long period, perform the following procedure:

    1. Clean off any dirt or grease that may have accumulated on the machine or any of the moving parts.

    2. Clean accumulated soil from the knives.

    3. Open the hood and clean out the inside of the machine.

    4. Lubricate all grease fittings.

    5. Support the PTO driveshaft in the stored position with the tether to prevent damage, or remove the PTO and store it under the hood to minimize corrosion.

    6. Touch up any scratches on the painted surfaces.

    7. Replace any missing or damaged decals.

    8. Store the machine inside a dry, secure building. Inside storage reduces maintenance, gives a longer working life, and increases the residual value of the machine. If inside storage is not available, cover the machine with a heavy sheet or tarpaulin and secure it tightly.
