Funzionalità principali
Built-In Pump with an Integrated Work Light
Smoke Starts in About 5 Seconds
The detector starts producing smoke quickly after power-on. Allow the test line to fill with smoke, then inspect for escaping smoke to locate leaks.
Low-Pressure Leak Detection
Supports low-pressure checks on EVAP, intake, exhaust, fuel-tank, vehicle-sealing, and common line-fitting areas.
Pompa dell'aria integrata
No extra air pump is required. The built-in air pump lets the unit operate without a separate shop-air supply.
Lightweight Hook Design
The compact body and hook design make it easy to position the unit near the test area, transport it, and store it after use.
Overheat and Low-Temperature Protection
Overheat protection turns off power when the unit exceeds 75°C, and the unit can operate at temperatures down to -20°C.

Istruzioni per l’uso:
Add Oil, Connect, Power, Inspect, and Retest
Add Testing Oil
For first use, fill 10–15 mL baby oil or liquid paraffin into the detector. Do not overfill.
Connect the Test Line
Access the system to be tested, position the smoke leak detector securely, then disconnect the line you want to test and connect it to the detector.
Connect 12V DC Power
Connect the smoke leak detector to a 12V DC battery, then turn on the power switch to start the detector.
Individua la perdita
After smoke fills the test line, inspect for escaping smoke to locate leaks. Use a headlamp if extra visibility is needed.
Confirm and Retest
Confirm any visible escape path against the system layout, repair the verified leak, and repeat the same controlled test. Continue with the vehicle procedure if no smoke is visible or the fault is intermittent or functional.
Sicurezza e compatibilità
Confirm System Pressure and Keep Ignition Sources Away
12V Power and Built-In Air Pump
Connect SDT106 to a 12V DC battery before use. The built-in air pump provides the test airflow, so you do not need an external compressor.
Use Visible Smoke Within the Low-Pressure Limit
SDT106 outputs less than 12 psi and less than 5 L/min. Because it has no pressure gauge, flow meter, or flow adjustment, use visible smoke to locate permitted low-pressure leaks and stay within the service limits for the system you are testing.
Testing Oil Is Not Included
Testing oil is not included. Use liquid paraffin or baby oil and add 10–15 mL before first use.
Limit Continuous Use to 8 Minutes
Do not run SDT106 continuously for more than 8 minutes. Let the unit rest between test cycles.
75°C Overheat Protection
Automatic overheat protection shuts off power if the internal temperature exceeds 75°C. Let the unit cool before using it again.
Operating Temperature and Hot Surfaces
SDT106 supports operation down to -20°C. The round metal housing can become hot during use, so avoid touching hot surfaces directly.
Follow the Service Limits for the System
Do not introduce smoke into any component or system excluded by the vehicle or component service procedure. SDT106 is for permitted low-pressure smoke testing, not high-pressure system testing.
Use Smoke to Locate the Leak
Use visible smoke to locate the leak area, then repair and retest. If no smoke appears, recheck isolation, flow, and the test setup before continuing.
Never Refill While Running
Do not refill testing oil while SDT106 is running.
No Pressure Gauge Provided
Do not estimate test pressure from the unit because SDT106 has no pressure gauge.
Stay Within Low-Pressure Limits
Keep the test within the low-pressure range allowed by the vehicle or component service procedure.

Eccellente.
Excellent. Everything arrived complete. Everything works. I tried it to find a jerk on a cold engine and rich mixture, and the smoke generator immediately showed a leak from under the throttle valve gasket. Quick and convenient, so you don’t have to look at half the car.

Add 20 ml of smoke oil, connected to the battery power, immediately out of the smoke, the airbag can be connected to the air intake hose, and then the smoke conduit is connected, the smoke quickly from the location where there is a leak out, very convenient.
