Component Descriptions
1. Cap Plug Kit is used to seal the intake ducting of
the engine being tested. The plugs range in size from
1-3/4" to 4-1/2", and may be used to seal either the
inside diameter of an opening, or flip them over and
seal the opening at the outside diameter.
2. EVAP Service Port Adapter (standard size)
connects directly to the factory service access port on
the vehicle when connecting to a vehicle's fuel vapor
recovery system.
3. Exhaust Cones taper in size from 1" to
3-1/2" with a 5/16" opening at the small
end of the cone to which a short section
of hose is connected. The supply nozzle
is inserted into the end of the attached
hose to introduce smoke into any system
with an opening that fits these dimensions.
The exhaust cones may also be used as
exhaust plugs when testing intake vacuum
systems.
4. Flow Meter with pointer-flag establishes a quick
PASS / FAIL when determining if the vehicle being
tested has a leak.
5. EVAP Service Port Adapter (small size) connects
to the factory service access port on some vehicles.
6. "ON" Indicator Light turns ON after pressing the
remote starter button, indicating the tester is ON.
(There is a five second self-diagnostic delay before
the light comes on.)
7. Power Indicator Light turns ON when connecting the
power leads to a battery, indicating a good contact.
8. Remote Starter & Power Cables are used to
operate the tester. The tester stays ON for five (5)
minutes after the remote button is pressed; press the
button again to turn the tester OFF.
9. Schrader Valve Removal / Installation Tool is
designed to work on many different kinds of vehicles.
10. Selector Switch is used to select the functions of the
tester as explained in this manual.
11. Spotlight helps locate smoke when searching for
leaks.
12. Smoke Diffuser is designed to slow the velocity of
the smoke exiting the supply hose. The diffuser allows
the operator to lay down a thick bed of smoke along
the door, sunroof, windshield, and window seams, so
any air disturbance caused by unwanted airflow may
be observed.

13. Supply Hose is used when confirming the integrity
of an EVAP system, when verifying any system for
leaks, or when introducing smoke into a system being
tested for leaks.
14. Hose (25 ft.) is used to deliver nitrogen to the EVAP
tester. Simply connect the 1/4" pipe thread to the
nitrogen regulator and the quick-disconnect fitting to
the EVAP tester.
Features Included But Not Shown Here
Drain / Fill Area (located on the top-back of the tester):
Much like a motor oil dipstick, there are low and high marks
engraved on the tester's dipstick. Remove the dipstick
to maintain the smoke solution level at the FULL mark,
and to drain and replace the smoke solution during yearly
maintenance service.
Smoke-Producing Solution: LeakMaster is shipped
with a full charge of smoke-producing solution – enough
to perform approximately 500 tests before needing a refill.
We recommend replacing the solution once a year (at the
minimum) to help keep the LeakMaster operating in a
like-new condition for many years to come.
Water Separator / Filter (on back of tester) ensures a
clean supply of nitrogen or air.
