NOTE: ______________________ __
Fully tighten the tool securing bolts, but
make sure the tool body is parallel with the
case. If necessary, one screw may be backed
out slightly to level tool body.
Use a soft hammer to tap on the case
half. Tap only on reinforced portions of
case. Do not tap on gasket mating sur-
face. Work slowly and carefully. Make
sure the case halves separate evenly. If
one end "hangs up", take pressure off
the push screw, realign and start over. If
the halves are reluctant to separate,
check for a remaining case screw or fit-
ting. Do not force.
