Husqvarna AR19B Owners Manual - Page 33

MAINTENANCE Cam lock for the handle Only applies to model AR19. 1. The cam lock (3) on the handle should lock if you press it with moderate force using your hand. The frame of handle (2) should be properly affixed to the machine. 2. Check the locking nut on the cam rod (1). If the nut is easy to turn by hand when the cam is released, it will no longer properly affix the handle and must be replaced for the lock to continue functioning safely. Adjustment Put the handle in working position and slowly tighten the locking nuts on the cam rod (1/4 turn at a time) until the cam lock functions with moderate manual pressure. IMPORTANT INFORMATION Excessive adjustment of the locking nut can damage the cam rod. Always replace nuts that become easy to turn so that the handle does not come loose. For the cam mechanism to operate easily, the edge of the cam should be lubricated with a small amount of grease. 8011-120 English - 31
