Product Introduction

Overview

The AUTOOL SDT205S is an automotive smoke leak detector specifically designed for automotive repair technicians. The SDT205S features dual testing modes: Air Mode and Smoke Mode. Air Mode allows technicians to determine if there is a leak through the pressure gauge without activating smoke. Smoke Mode is independently controlled by the smoke generator, enabling precise identification of the leak location once a leak is detected. Additionally, the visualized flowmeter effectively monitors and controls the smoke output flow, while the visualized pressure gauge accurately determines whether there is a pipeline leak.

AUTOOL SDT205S is suitable for all pipes of cars, motorcycles, snowmobiles, off-road vehicles, dune buggies, light trucks, and speedboats. It's recommended to use an automobile diagnosis tool to work with SDT205S to detect car engine problems more quickly.

Any other use is considered beyond the intended purpose of the equipment and is prohibited.

Working Theory

Low oxygen combustion
The AUTOOL smoke leak detector employs a forced combustion smoke generation method in a low oxygen environment. It is energized by a conductive column to the heating wire, which rapidly heats up to more than 300°C so that the mineral oil reaches the ignition point and enters the state of combustion. Due to the small intake of air flow, it is insufficient to provide sufficient oxygen to maintain full combustion, thus the combustion mainly occurs on the surface of the heating wire. Subject to high-temperature heating, the mineral oil retention object can continue to burn insufficiently around the heating wire, thus producing a large amount of smoke.

Operations Instruction

Preparation Before Use

• Place the detector on the mobile cart or under the hood.
• Open the filling cap and drain 10ml of test liquid into the filling port (A). NOTE: If the test oil is overfilled, please drain some oil out through the oil drain outlet (I).
• After completing the first two steps, start using the SDT205S.

Detail Operation During Use

• Connect the smoke hose to the smoke outlet (J) and the power cable to the power socket (K).
• Attach the power cable clips to a DC12V car battery. NOTE: Connect the red clip to the positive terminal (+) and the black clip to the negative terminal (-). To achieve the best performance from the smoke leak detector, the car battery should be fully charged in advance.
• NOTE: This device is only allowed to use a DC12V vehicle battery as its power source.
• Press the air mode switch (B) to start generating pressurized air.
• Press the smoke mode switch (C) to start generating smoke. NOTE: The smoke output can be controlled using the Smoke Flow Adjustment Valve (F).
• Press the smoke mode switch (C) again to stop smoke output.
• If the product is not used for a long time, it is recommended to pour out the remaining smoke oil for storage.

Operation Guidelines for Automobile Pipeline Inspection

• Turn off the engine ignition switch. NOTE: All leak detection of automobile piping systems must be performed with the engine turned off.
• Remove the air filter. For some vehicles, the throttle valve may also need to be removed.
• Clean the inner wall of the test interface and install the conical adapter onto the test pipeline.
• Attach the smoke pipe to the smoke outlet (J) of the machine and plug the power cord into the power interface (K) of the machine.
• The machine is powered by a DC12V car battery.
• Press the air mode switch (B); the conical head on the smoke pipe will output air pressure.
• Press the smoke mode switch (C) and wait for about 10 seconds. Once the smoke thickens, insert the conical head of the smoke pipe into the conical adapter.
• Wait for approximately 1-2 minutes. Use a strong flashlight to assist in locating the pipeline leak and assess the leakage situation.
• After completing the test, turn off both the air mode switch (B) and the smoke mode switch (C).
• NOTE: If only part of the system needs to be tested or if the system being tested has other openings that need to be sealed, a plug kit can be used, which can also be used to seal the intake manifold.

WARNING
When the internal temperature reaches 75°C, the detector will start self-protection function and stop working automatically.

Instruction of Smoke Leak Detector Pressure Gauge

The smoke leak detector pressure gauge has two main functions: one is for machine self-test, and the other is used for leak judgment. It can be used to initially determine the leakage of piping system through the change of pressure gauge pointer. If the pointer of the pressure gauge keeps still, which represents there is a relatively serious leak in the pipeline. The pressure gauge pointer will rise to a fixed pressure value only if the area of the piping system currently being tested is relatively small. And if there is a leak, the pressure gauge pointer will drop or become unstable. In this case, you can turn on the smoke switch to output smoke to locate the leak.

Airbag Adapter Instructions

Airbag adapters are suitable for non-circular connections. While for round and oval ports, please use the inlet tapered adapter for normal cases.

• Before using the airbag adapter, be sure to clean the inner wall of the intake manifold (or other test interfaces) to prevent sharp protrusions from piercing the airbag adapter.
• Put the air bag (Z) into the test port.
• Press the hand pump (X) until the bladder (Z) inflates and fully seals the test port.
• Connect the cone head on the smoke outlet pipe with the smoke guide pipe (Y), introduce gases and smoke into the duct to be tested.
• After the test is completed, turn the pressure relief valve (W) counter clockwise, take out the car air inlet adapter from the test port, clean and save it.

NOTE: Airbag adapter can not contact with corrosive oil.

About Smoke Test Oil

This product needs to use special test oil. It's recommended to purchase liquid paraffin or baby oil as test oil if you cannot find special test oil locally.

It is recommended to use the filling bottle with the capacity mark in the accessories of the packing to fill in new oil.

Too much test oil in the machine can affect smoke output; please discharge part of the liquid through the oil discharge port.

If the product is not used for a long time, it is recommended to drain out the remaining test oil for preservation.
