This service manual provides specifications in both Metric
(SI)
and
U.S.
Customary systems of measurement. The first
specification
is
given in the measuring system perceived by us to be the preferred system when servicing a particular
c
o
mp
o
n
e
n
t,
while the second specification (given in parenthesis) is the converted measurement. For instance, a specifica
t
ion of
"0.28
mm
(0.011
inch)" would indicate that we feel the preferred measurement is the metric system of measure
ment and the
U.S.
Customary equivalent of
0.28
mm is
0.011.
