   A - Spring Balance

   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:

   339 Baler:

   • 180—230 N (40—51 lb.)
   • 540—690 N·m (390—500 lb.-ft.)
   
   

   349 Baler:

   • 220—270 N (49—60 lb.)
   • 660—810 N·m (477—585 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.
