   B - Lever

   C - 90° Angle

   IMPORTANT: Check slip clutch to be sure linings are not bonded to metal plates.

   Check clutch slippage using spring balance (A) and 3 m (10 ft) lever (B) attached to power shaft. Exert force at an angle of 90° (C).

   For proper force on lever for clutch slippage, refer to the following specifications:

   359 Baler:

   • 240—290 N (53—65 lb.)
   • 720—870 N·m (520—629 lb.-ft.)
   
   

   459 Baler:

   • 315—360 N (70—80 lb.)
   • 945—1080 N·m (683—781 lb.-ft.)

IMPORTANT: Excessive slippage will damage the slip clutch. A slip clutch adjusted too tight will not give any protection to the power train.
