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.
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.
