A - Lockout Valve Lever

Precutter knives are extremely sharp and can move without warning. To avoid serious injury, shut off all power and engage the knife cylinder lockout valve lever (A) in the locked position before servicing the knives or unclogging the baler. Prevent personal injury by wearing suitable gloves when handling knives.

Always keep precutter knives sharp. Sharp knives save power and provide higher capacity.

Sharpen knives every 10 hours of operation. Depending on crop conditions, a more frequent sharpening schedule is necessary.

  1. Remove knife from the machine. (See Remove and Install Precutter Knives in Preparing the Baler section.)

    B - Grinding Edge

    Clamp knife in a vise as shown.


  3. Knives are sharp. Prevent personal injury by wearing suitable gloves when handling knives.

    Protect eyes. Flying metal debris and sparks can cause serious injury. Always wear appropriate eye protection when sharpening knives.

    Avoid overheating metal during sharpening. To avoid overheating the cutting edge, keep the flap wheel moving along the edge of the knife and remove small amounts of material in each pass. If the steel is blued, it decreases the integrity of the blade leaving it brittle and a cutting edge that will not last.

    Sharpen knives using a flap wheel grinding disk (A) at a 12° ±2° angle.

  4. Maintain a maximum grinding edge (B) of 10 mm (0.5 in).

  5. To reinstall the knife (see Remove and Install Precutter Knives in Preparing the Baler section).
