When in use the blade will rotate off-center effecting usability
An overlooked mistake whenever it comes to blades as it can be as simple as being out of line. Check blade before use and make sure the blade is straight or isn’t loose. Performing this task before plugging the device in for use will ensure the blade properly aligns within the machine.
The blade could be rotating off center because it’s not properly secured to the motor. After prolonged use, the blade can be knocked around and be pushed out of place. Therefore, checking the blade connection to the motor periodically will reduce unnecessary damage to the motor or blade being rotated off center.
The front does not come on when the button is pressed
The LED could not be working because the device is not plugged into the wall. Check to make sure your device is plugged into the wall. If this does not fix your problem your cord may need replacing. Check out our replacement guide for “Cord Replacement”.
The front-facing LED has burned out from overuse, or damage to the device and needs to be replaced. Check out our replacement guide for “LED Light” for instructions.
The blade of the device gets very hot after long use
The material that you are working with is not made for the type of blade or the tool itself. Materials that are too hard will heat the cause heat build up for the tool.
The tool is cutting the material but still getting hot. This can be from general overuse and can be fixed by setting the tool aside and letting it cool down. A dull blade could also be the cause, check blade and consider replacing it.
Grease is leaking from the head of the tool.
This could be due to an O-ring on the bottom section of the head being broke or stretched. If the O-ring is broken or stretched, it could cause grease to leak through and will need to be replaced.
The grease could be leaking if there is an issue with the internal rubber bearings. If these are damaged it could cause grease to leak out of the head. The head will also not function properly if there are issues with the internal rubber bearing. If this is the case then the bearings will need to be replaced.
One cause for grease leaking out of the head could be from a crack. The user should check the head for small cracks if grease is leaking out of the head. If a crack is found then the entire head of the tool will need to be replaced.
The torque of the motor seems to be decreased
Dust and other materials may have built up in the tool and are causing issues with the flow of electricity within the motor. Use compressed air to blow out the device.
Due to prolonged usage, the brushes may have worn down over time and are no longer providing strong electrical contact. Check out the brushes replacement guide.
Due to extreme, long term overloading the motor has worn down and is unable to produce a usable amount of power. Check out the motor replacement guide.
