swing speed valve. This valve allows the operator to

valve mounted on the swing motor inside the crane
frame. The valve has an adjustment screw with a lock
collar. Loosen the lock collar when adjusting the speed,
then tighten the lock collar to maintain swing speed limit
setting. Turning the knob counterclockwire reduces the
rotation speed. The adjustment dial allows the maxi-
mum swing speed to be reduced as follows:
