Milton Industries Test Equipment S1253 - Hand Held Compression Tester - Manual

WHY A SPARE VALVE CORE?
Any compression tester can develop leakage – usually when you are right
in the middle of an engine test. But with the exclusive Milton spare valve
core feature, you're back in business within two minutes. Unscrew gage
cover to remove valve core.
NOTE: This is not a standard tire valve. Replace with Milton No. 1251-2.
HOW TO USE YOUR NEW MILTON COMPRESSION TESTER
1) Run engine until completely warmed up.
2) Shut off engine, blow foreign matter from around spark plugs with air hose.
3) Remove spark plugs and gaskets.
4) Insert rubber nose piece of tester into spark plug hole. Hold firmly.
5) Crank engine four full compression strokes. Record pressure of each cylinder.
6) Consult manufactures specs on car being tested. Usually reading should not
vary more than 10% from cylinder to cylinder, (generally not more than 15 lbs.
on a high compression engine or more than 10 lbs. on a low compression
engine).
