To adjust the blade tension, first ensure the bandsaw is turned off and unplugged. Use the tension adjustment knob located on the upper wheel housing. Turn the knob clockwise to increase tension and counterclockwise to decrease it. Refer to the tension gauge for optimal settings.
It is recommended to clean the bandsaw after each use, check the blade tension and alignment weekly, lubricate moving parts monthly, and inspect the electrical components bi-annually.
First, ensure the power cord is properly plugged in and the power switch is on. Check the fuse or circuit breaker for any issues. Inspect the power switch and wiring connections, and verify that the motor overload protection hasn't tripped.
For cutting metal, use a bi-metal blade with 14-18 TPI (teeth per inch). Ensure the blade size matches the bandsaw specifications, typically 2500mm in length for the CBS250B model.
To change the blade, turn off and unplug the bandsaw. Release the blade tension, open the wheel covers, and carefully remove the old blade. Install the new blade, ensuring it's properly seated on the wheels, then adjust the tension and close the covers.
Blade drifting can result from improper tension, misalignment, or a dull blade. Check and adjust the blade tension, ensure the blade guides and bearings are aligned, and replace or sharpen the blade if necessary.
Always wear appropriate personal protective equipment, such as safety glasses and gloves. Ensure the work area is clean, keep hands away from the blade, and never operate the bandsaw without the blade guards in place.
To align the blade guides, loosen the guide adjustment screws, position the guides so they are just behind the blade teeth, and re-tighten the screws. Make sure the guides are parallel to the blade and evenly spaced.
Unusual noises may be caused by loose parts, worn bearings, or improper blade tension. Inspect the bandsaw for loose components, check the bearings for wear, and ensure the blade is correctly tensioned.
To improve cutting accuracy, ensure the blade is sharp and properly tensioned, align the blade guides correctly, and use a fence or miter gauge for straight cuts. Regularly check the table alignment and adjust as necessary.
