10 Machine the valve seat by cranking
clockwise while turning the feed screw.
Never turn anticlockwise, as this could
damage the cutter. Lubricate with cutting oil
while machining.
11 When the surface of the valve seat has been
machined, reduce the cutting pressure by
turning 2-3 revolutions without any feed.
Continue turning while backing off the feed
screw. The valve seat cutter is now ready for
the next valve seat.
The valve seats can also be machined using
tools from kit 587
061.
