2. introDuction & sPecification
● Allows the technician to pinpoint all manner of system
leaks including air intake, cooling, evaporation, fuel,
exhaust and vacuum systems.
● Fast and simple to use, maximising earning potential.
● Features single button operation, flow control and
auto power-off.
● Uses mineral (baby) oil and workshop air supply to
generate smoke at low pressure whilst connected
to a vehicle.
● System is clean and quick to use and connects to a
12V vehicle battery.
● Four rubber cones included.
● Mineral oil NOT included.

3. oPeration
3.1 Before initial use, soak the fibreglass element/Wick in mineral (baby) oil. failure to carry this out will lead
to the fibreglass element burning out immediately. The fibreglass element is considered to be a
consumable item and is not covered by warranty.
3.2
Take top off Oil Filler ( see fig.1) and fill with mineral based baby oil (maximum: 75ml). The sight glass on
the right-hand side of the unit shows the oil level.
3.3 Connect to workshop air supply using the quick connector on the left-hand side of the unit (see fig.1).
the inlet air pressure needs to be regulated to no more than 14psi (1bar).
3.4 connect to 12V battery; green indicator light will show.
3.5 Press Heater Button on front of unit; red light will show indicating that the heater element is active. the
heater element is timed to operate for 4¾ minutes, after which time it will switch off automatically.
3.6 Do not remove the oil filler cap whilst the unit is operating or is connected to an air supply as this will
cause oil (which could be hot) to be forced from the filler neck.
3.7 from cold, the heater may need to be activated more than once to achieve the required temperature
necessary for vaporisation.
3.8
Once smoke is starting to issue from the hose it may be necessary to temporarily increase the air flow
using air flow control (see fig.1). This will clear any excess oil.
3.9 The required volume of smoke can be achieved by adjusting the air flow rate, using the air flow control
and gauge for reference.
3.10 the smoke produced can be used in many ways to indicate the presence of leaks in either pressure or
vacuum systems. When smoke is introduced into the locality of the suspected leak, it will be carried by
the flow of air either to or from the aperture, depending on the system. Observing the behaviour of the
smoke will pinpoint the problem.
3.11 Alternatively, smoke can be introduced into ducting by unfastening one end of the duct and plugging with a
suitable rubber cone from those included in the kit (see fig.2) . the hose from the machine can then be
coupled to the bush in the cone and the duct filled with smoke. Any leak will be displayed by a
jet of smoke coming from it.
3.12 the amount of smoke needed will vary with the capacity of the system being investigated.
3.13 if the smoke starts to dwindle, the heater element will need to be switched on for a further time.
