The device won’t hold a charge.
The battery dies quickly.
Faulty Batteries
Remove the battery and plug it into the charger. On the side of the charger, there is a light that will signify the status of the battery. If it’s flashing quickly, that means that the battery is too hot or cold to function. A slow flashing red means that the charge is pending. If it’s flashing red or green, then it is a damaged/faulty battery pack. Different chargers will vary. Check out this guide on how to replace a faulty battery.
Faulty Charger
Test the charger by using a voltage meter. If there is no reaction, replace the charger from a trusted purchasing source.
The clamp is no longer holding the blade.
The clamp will not hold onto the sawing mechanism.
Faulty Blade Clamping Mechanism
Check for debris inside the clamp slot to ensure that it’s clean. Dirt and debris can build up in the blade clamping mechanism, inhibiting it to hold onto the saw. You can clean the blade clamping mechanism by using a small brush to wipe out the debris. If there is no debris in the clamping mechanism, ensure that the blade itself is being installed correctly. If it’s clean and still not clamping, check this guide for replacement methods.
The trigger is stuck.
The trigger is stuck in a single position.
Sticky/Locked-up Trigger
Attempt compressing the trigger past its return point to see if it will bounce back. Next, try pulling on the trigger cover to see if you can return it to the starting position manually. If you still cannot get your trigger to return to its resting state, see this guide on methods to replace a locked-up trigger.
The unit’s motor doesn’t seem to be working.
The motor is not turning on.
Motor Locked Up
If there is clearly power going to the motor and it’s creating a humming noise, then the motor might be locked up. Open up the motor to check and see if the gears are stripped so that you can accurately assess what needs to be replaced. See this guide for further instructions on replacing the motor.
Gearbox Failure
If you can hear the motor running but it’s slow or has jerky movements, see troubleshooting section entitled “Gearbox Failure” below.
The gear is worn down and is making less contact with other gears.
The gearbox is failing.
Gearbox Failure
If you hear the motor running and the gears slipping, turn off the device and begin deconstructing it to isolate the problem. Visually inspect the gears to determine which ones need to be replaced. See this guide on how to replace the gearbox kit.
