4. Setup
4.1 Unpacking
Carefully remove the dust collector and all accessories from the packaging. Retain the packaging for future transport or storage.
4.2 Connecting the Dust Pipe
- Locate the dust pipe connection port(s) on the rear of the unit. The JT-26B features a "Y" type suction inlet, allowing for connection to two separate workstations simultaneously.
- Attach the provided dust pipe(s) securely to the inlet port(s).
- Connect the other end of the dust pipe(s) to your sandblaster, lathe, grinder, or workstation's dust extraction outlet.

4.3 Power Connection
- Ensure the dust collector's power switch is in the "OFF" position.
- Connect the power cord to the power inlet on the unit.
- Plug the power cord into a grounded electrical outlet that matches the specified voltage (220V or 110V).
5. Operating Instructions
5.1 Powering On/Off
To power on the unit, flip the main power switch to the "ON" position. To power off, flip the switch to "OFF".
5.2 Adjusting Suction Power
The JT-26B features voltage stepless regulation. Use the control knob on the external control box to adjust the suction power as needed for your application. Turn the knob clockwise to increase suction and counter-clockwise to decrease it.
5.3 Carbon Brush Monitoring System
This dust collector is equipped with an automatic time system for carbon brush abradability and a prewarning system. When the carbon brush wear approaches a critical point, the system will automatically trigger an alarm and cut off the power supply. This feature protects the motor from damage and extends its operational lifespan. When the alarm sounds, it indicates that the carbon brushes require inspection and potential replacement.
5.4 Dual Workstation Use
The "Y" type suction inlet allows two users to work simultaneously, connecting two separate dust-generating devices to the single dust collector.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your dust collector. Always disconnect the power before performing any maintenance.
6.1 Dust Bag Replacement
- Open the front door of the dust collector.
- Carefully remove the full dust bag.
- Install a new dust bag, ensuring it is properly seated and sealed within the compartment.
- Close the front door securely.

6.2 Filter Cleaning/Replacement
The internal filter should be regularly inspected and cleaned to maintain optimal suction. Depending on usage, the filter may need to be replaced periodically. Refer to the filter manufacturer's guidelines for cleaning and replacement intervals.
6.3 Carbon Brush Inspection/Replacement
When the prewarning system activates, it indicates that the carbon brushes are nearing the end of their service life. Disconnect power and consult a qualified technician or the manufacturer's support for carbon brush inspection and replacement to prevent motor damage.
6.4 General Cleaning
Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
