1. Prior to removing spark plugs, clean area around spark plugs using compressed air to free loose debris
that could fall into the cylinder upon spark plug removal.
2. Remove all spark plug wires and spark plugs from engine.
3. Remove air cleaner or intake tube, oil ller cap, radiator cap and dipstick. This will assist in locating
source of excessive leak.

5. Turn the regulator knob fully counter-clockwise. Connect the leakdown tester to a compressed air source.
6. Set the air compressor’s regulator to 7 psi to 100 psi. Never operate tool with more than 100 psi inlet
pressure or damage to the tool can result.
7. Turn the regulator knob clockwise until the cylinder leakage gauge reads “0” at the end of the yellow band.
8. Hand screw the adapter hose into the spark plug hole of the cylinder to be tested. Connect the male end
of the adapter hose to the female coupler of the extension hose.
