2. intrOductiOn
designed to detect a variety of common engine faults including: worn piston rings, worn valves, cylinder head cracks and blown head gaskets.
twin gauge manifold shows percentage of cylinder leakage and cylinder pressure. suitable for use on any petrol engine with 14, 12 or 10mm spark
plugs.
3. air suPPly
the recommended hook-up is shown below.
3.1.
ensure that the air valve regulator is in the “off” position before connecting to the air supply.
3.2.
You will require an air pressure of 45 to 100psi.
Warning!
ensure the air supply is clean and does not exceed the pressure quoted. too high an air pressure and/or unclean air
will shorten the life of the tester due to excessive wear and may be dangerous, causing damage and/or personal injury.
3.3.
drain the compressor air tank daily. Water in the air line will damage the tester.
3.4.
clean compressor air inlet filter weekly.
3.5.
line pressure should be increased to compensate for unusually long air hoses (over 8 metres). the minimum bore for hose and
fittings is 1/4”.
3.6.
Keep hoses away from heat, oil and sharp edges. check hoses for wear and make certain that all connections are secure.

OPeratiOn
OVerVieW.
once the leakage tester has been connected to one of the cylinders compressed air is fed into that particular cylinder
through the built in pressure regulator. diagnosis is made by observing the amount of leakage that is indicated on the cylinder leakage
gauge and by listening for leakage at various points of the cars system.
