Blade Falls Out While Cutting
The cutting blade falls out of the tool while cutting material.
Dirt Inside The Blade Holder
Dirt inside of the blade holder can cause the blade to not seat correctly in the holder. This will cause the blade to fall out during use. Clean the holder with water to remove all the dirt and grime. Once clean, place a few drops of oil in the blade opening of the holder. Reinstall blade and make sure the blade is securely held by the holder.
Incorrect Size Blade
Some manufacturers’ blades say that they are universal but may not be the proper shape for the holder. Try using a different blade. If that still does not fix the problem try using a Ridgid name brand blade.
Blade Holder Is Broken
If cleaning the holder and a new bald does not fix the problem the blade holder is faulty. The holder will need to be replaced. Refer to blade holder replacement guide.
Motor Spinning But No Blade Movement
The motor is spinning inside of the housing, but the blade is not moving.
Check to see if the case is starting to come apart. If it is the screws may be tightened to fix the problem, but if the screws are stripped a new housing may be needed.
Broken Or Loose Drive Arm
The housing will need to be taken apart to have access to the drive arm of the ring gear. This gear should be driven by the motor. If the ring gear is turning and the drive arm is either broken or unattached this will cause the blade not to move. If this is the case either the broken arm will have to be replaced or the attachment point of the ring gear will need to be fixed.
Ring and Pinion Gear Is Worn
The housing will need to be taken off to have access to the ring and pinion gear. When checking the gears make sure that the pinion gear (off the motor) and the ring gear (attached to the drive arm) have good teeth and are making contact with each other. If the gears are not making good contact or the teeth are worn down, the gears may need to be replaced.
Safety Switch Will Not Unlock
The safety switch will not move.
Dirt or Debris In Switch
Visually inspect the safety switch to check for any dirt or debris that could be preventing it from unlocking. Sometimes with use the tool can get dirt into the switch which will jam the moving parts of the switch.
Broken Safety Switch
Visually inspect the locking mechanism for any damage. Over time and with heavy use the switch can break and fail. If the switch is damaged the switch will need to be replaced.
Battery Will Not Lock Into Place
The battery will not lock into the tool.
Debris Stuck In The Battery Lock
Sometimes debris can fall onto the battery lock while using the saw. This can cause the battery lock to jam. Clean any debris that is found in the battery lock. Once clean check to see if the lock is fully functional.
Debris Stuck In The Battery Slot
Debris can also fall into the battery slot easily. Inspecting the battery slot on the saw for any debris that may have fallen in the slot while the saw was being used. Dust or debris could ultimately prevent the securing of the battery into place. The debris can prevent the contacts on the battery from making proper contact with the tool.
Damaged Or Broken Battery
Inspect the battery to see if it looks broken or damaged. This could cause the battery to not be able to lock in correctly. If the battery is broken or damaged the battery will need to be replaced with a new one.
Damage Or Broken Battery Slot
Inspect the battery slot on the saw to determine whether it looks damaged or broken. If it is broken the battery slot will need to be replaced.
Saw Does Nothing When Trigger Is Pushed
When the trigger is pushed the saw does not run.
Battery Is Not Locked Into Place
Sometimes the battery may look like it is fully in the battery holder, but it is not fully locked into place. Make sure the battery is fully locked into the housing. This will ensure that the battery contacts will be fully engaged with the tool.
Battery Is Uncharged
A dead battery will cause the tool no to function. Make sure that you have fully charged battery.
Batteries wear out over time and lose their ability to hold a charge. Most charging stations have a way to tell you when you have a bad battery. If your charging station does not have this feature, try using a different fully charged battery.
Battery Contacts Are Damaged Or Debris Is Stuck In The Holder
Check and make sure that there is no dirt or debris on the battery’s contacts. Sometime debris can damage the contacts of the battery and the battery holder. If cleaning the contacts does not work then, the battery holder may need to be replaced. To complete this task, you can use this repair guide.
Trigger And Safety Switches Are Not Fully Functional
Check and see if the triggers have full movement and feel smooth. Sometimes the trigger can become jammed with dirt and will need to be cleaned to remove the problem.
Broken Or Loose Drive Arm
If the motor is still spinning when the trigger is pushed, then there is a drive issue from the motor to the blade. The housing will have to be taken apart to assess the issue that is present. See this repair guide for the instruction.
If None Of The Above Topics Fix The Problem
If all previous conditions have been checked and are in order, then the saw must be taken apart to inspect all of the internal components for damage. It is also possible that there is a problem with the motor.
